自动化运维——saltstack 、ansible

1、自动化运维介绍

传统运维：传统运维效率低，大多工做须要人工完成，工做繁琐，容易出错，每日重复作相同的事情，没有标准化流程，脚本过多，不方便管理。html

自动化运维:解决上面全部问题。node

常见自动化运维工具:python

Puppet：基于rubby开发，c/s架构，支持多平台，可管理配置文件、用户、cron任务、软件包、系统服务等。分为社区版和企业版，企业版支持图形化配置。

Saltstack：基于Python开发，c/s架构，支持多平台，比Puppet轻量，在远程执行命令时很是快捷，配置和使用比puppet容易，能实现puppet几乎全部的功能。

Ansible：更加简洁的自动化运维工具，不须要在客户端上安装客户端软件，基于Python开发的。能够实现批量操做系统配置、批量程序的部署、批量执行命令。

2、saltstack安装与启动

saltstack介绍文档： https://docs.saltstack.com/en/latest/topics/index.htmllinux

saltstack操做方式ios

使用salt-ssh远程执行，相似ansible，

支持c/s模式

如今按照c/s模式使用，须要准备三台台机器：nginx

hostname	IP	功能
ying01	192.168.112.136	master
ying02	192.168.112.138	minion
ying03	192.168.112.139	minion

先分别在ying0一、ying0二、ying03上，设置hostsgit

# vim /etc/hosts

三台机器都设置同样

192.168.112.136 ying01
192.168.112.138 ying02
192.168.112.139 ying03

在ying01上：web

安装repo仓库，而后安装 salt-master 和salt-minion包sql

[root@ying01 ~]# yum install -y  https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.no

[root@ying01 ~]# yum install -y salt-master salt-minion

编辑配置文件mongodb

[root@ying01 ~]# vim /etc/salt/minion

#master: salt  改成  master: ying01

开启salt-master服务，并查看进程以及监听端口

[root@ying01 ~]# systemctl start salt-master； systemctl start salt-minion    //开启salt-maste和minion服务
[root@ying01 ~]# ps aux |grep salt

[root@ying01 ~]# netstat -lntp|grep python
tcp        0      0 0.0.0.0:4505            0.0.0.0:*               LISTEN      36619/python

监听端口4505 做用是发布消息；也就是zeromq.x86_64 0:4.1.4-7.el7，这个包的端口。
监听端口4506 做用是salt-master和salt-minion通讯

ying0二、ying03上:

安装repo仓库，而后安装salt-minion包(注意：客户端只安装minion包)

[root@ying02 ~]# yum install -y  https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.no

[root@ying02 ~]# yum install -y salt-master salt-minion

编辑配置文件

[root@ying02 ~]# vim /etc/salt/minion

#master: salt  改成  master: ying02          //ying03机器应写ying03

开启salt-minion服务，并查看进程；（注意：服务端没有监听端口，只在服务端）

[root@ying02 ~]# systemctl start salt-minion
[root@ying02 ~]# ps aux |grep salt
root      5978  0.7  1.1 313768 21396 ?        Ss   12:14   0:00 /usr/bin/python /usr/bin/salt-minion
root      5981  3.3  2.2 567256 42456 ?        Sl   12:14   0:01 /usr/bin/python /usr/bin/salt-minion
root      5989  0.0  1.0 403992 20088 ?        S    12:14   0:00 /usr/bin/python /usr/bin/salt-minion
root      6068  0.0  0.0 112720   980 pts/0    S+   12:15   0:00 grep --color=auto salt

ying03和ying02机器，做为客户端，操做步骤同样；

3、saltstack配置认证

master端和minion端通讯：

须要创建一个安全通道，传输过程须要加密，因此得配置认证，也是经过密钥对来加密解密的。

认证的过程：

minion在第一次启动时会在/etc/salt/pki/minion/下生成minion.pem和minion.pub，其中.pub为公钥，它会把公钥传输给master。

master第一次启动时也会在/etc/salt/pki/master下生成密钥对，当master接收到minion传过来的公钥后，（经过salt-key工具接受这个公钥）就会在/etc/salt/pki/master/minions/目录里存放刚刚接受的公钥，同时客户端也会接受master传过去的公钥，把它放在/etc/salt/pki/minion目录下，并命名为minion_master.pub

通讯过程须要借助salt-key工具来实现。

salt-key命令用法

参数做用

-a 后面跟主机名，认证指定主机

-A 认证全部主机

-r 跟主机名，拒绝指定主机

-R 拒绝全部主机

-d 跟主机名，删除指定主机认证

-D 删除所有主机认证

-y 省略掉交互，至关于直接按了y

参数	做用
-a	后面跟主机名，认证指定主机
-A	认证全部主机
-r	跟主机名，拒绝指定主机
-R	拒绝全部主机
-d	跟主机名，删除指定主机认证
-D	删除所有主机认证
-y	省略掉交互，至关于直接按了y

在ying0二、ying03上，salt-minion服务启动下，/etc/salt/pki/minion/生成私钥和公钥

[root@ying02 ~]# ls /etc/salt/pki/minion/     //minion端的私钥和公钥
minion.pem  minion.pub
[root@ying02 ~]# cat /etc/salt/pki/minion/minion.pub       //minion端的公钥

在ying01上，/etc/salt/pki/master下生成密钥对

[root@ying01 ~]# ls /etc/salt/pki/master/
master.pem  master.pub  minions  minions_autosign  minions_denied  minions_pre  minions_rejected

参考博客：salt-key收集的主机名与实际主机名不一致

有一点疑点未解决，但不影响试验

个人理解是，既然ying01也被本身认证，此时的/master/minions/ying01的内容应该和maste.pub公钥同样，可是下面却明显不一致。

4、saltstack远程执行命令

salt '*' test.ping：测试全部认证主机是否存活

[root@ying01 ~]# salt '*' test.ping    
ying02:
    True
ying03:
    True
ying01:
    True

注意：这里的*必须是在master上已经被接受过认证的客户端，能够经过salt-key查到，一般是咱们已经设定的id值。也能够指定一个认证用户，好比 salt 'yin01' test.ping

salt '*' cmd.run "命令" ：在全部认证用户上执行命令

[root@ying01 ~]# salt '*' cmd.run "hostname"       //显示全部机器的主机名
ying03:
    ying03
ying02:
    ying02
ying01:

ying02:
    ying02
[root@ying01 ~]# salt 'ying0[23]' cmd.run "hostname"      //显示0二、03
ying03:
    ying03
ying02:
    ying02

salt -L 'ying01,ying03' cmd.run "hostname" 显示指定多个用户，中间用逗号隔开

[root@ying01 ~]# salt  -L 'ying01,ying03' cmd.run "hostname"  
ying01:
    ying01
ying03:
    ying03

salt -E 'ying[0-9]+' cmd.run "hostname" -E 可使用正则

[root@ying01 ~]# salt  -E 'ying[0-9]+' cmd.run "hostname"
ying01:
    ying01
ying02:
    ying02
ying03:
    ying03
[root@ying01 ~]# salt  -E 'ying0[0-9]' cmd.run "hostname"
ying02:
    ying02
ying01:
    ying01
ying03:
    ying03
[root@ying01 ~]# salt  -E 'ying[0-9]' cmd.run "hostname"
ying03:
    ying03
ying02:
    ying02

ying03:
    ying03
ying02:
    ying02
[root@ying01 ~]#

5、saltstack – grains

grains是在minion启动时收集到的一些信息，好比操做系统类型、网卡ip、内核版本、cpu架构等。

默认grains配置

在master端ying01上，列出ying02机器上grains项目名字

[root@ying01 ~]# salt 'ying02' grains.ls 
ying02:
    - SSDs
    - biosreleasedate
    - biosversion
    - cpu_flags
    - cpu_model
    - cpuarch
    - disks
    - dns
    - domain
    - fqdn
    - fqdn_ip4
    - fqdn_ip6
    - gid
    - gpus
    - groupname
    - host
    - hwaddr_interfaces
    - id
    - init
    - ip4_gw
    - ip4_interfaces
    - ip6_gw
    - ip6_interfaces
    - ip_gw
    - ip_interfaces
    - ipv4
    - ipv6
    - kernel
    - kernelrelease
    - kernelversion
    - locale_info
    - localhost
    - lsb_distrib_codename
    - lsb_distrib_id
    - machine_id
    - manufacturer
    - master
    - mdadm
    - mem_total
    - nodename
    - num_cpus
    - num_gpus
    - os
    - os_family
    - osarch
    - oscodename
    - osfinger
    - osfullname
    - osmajorrelease
    - osrelease
    - osrelease_info
    - path
    - pid
    - productname
    - ps
    - pythonexecutable
    - pythonpath
    - pythonversion
    - saltpath
    - saltversion
    - saltversioninfo
    - selinux
    - serialnumber
    - server_id
    - shell
    - swap_total
    - systemd
    - uid
    - username
    - uuid
    - virtual
    - zfs_feature_flags
    - zfs_support
    - zmqversion

salt 'ying02' grains.items 列出ying02机器上grains项目以及值

[root@ying01 ~]# salt 'ying02' grains.items   //篇幅关系，只列出部分
ying02:
    ----------
    SSDs:
    biosreleasedate:
        07/31/2013
    biosversion:
        6.00
    cpu_flags:
        - fpu
        - vme
        - de
        - pse
        - tsc
        - msr
        - pae

salt 'ying02' grains.item dns 列出ying02机器上grains中dns项目及其值

[root@ying01 ~]# salt 'ying02' grains.item dns
ying02:
    ----------
    dns:
        ----------
        domain:
        ip4_nameservers:
            - 119.29.29.29
        ip6_nameservers:
        nameservers:
            - 119.29.29.29
        options:
        search:
        sortlist:
[root@ying01 ~]# salt 'ying02' grains.item hwaddr_interfaces   //一样列出hwaddr_interfaces项目的值
ying02:
    ----------
    hwaddr_interfaces:
        ----------
        ens33:
            00:0c:29:c6:2c:24
        ens37:
            00:0c:29:c6:2c:2e
        lo:
            00:00:00:00:00:00

自定义grain文件

在客户端ying02上新建vim /etc/salt/grains文件，并重启salt-minion服务

[root@ying02 ~]# vim /etc/salt/grains

role: nginx      
env: test

[root@ying02 ~]# systemctl restart salt-minion.service

salt '*' grains.item role env ：列出role、env项目的值

[root@ying01 ~]# salt '*' grains.item role env
ying02:
    ----------
    env:
        test
    role:
        nginx
ying03:
    ----------
    env:
        test
    role:
        httpd
ying01:
    ----------
    env:
    role:


[root@ying01 ~]# salt '*' grains.item feng  //feng无定义此项目，因此显示无
ying02:
    ----------
    feng:
ying03:
    ----------
    feng:
ying01:
    ----------
    feng:

6、saltstack – pillar

pillar和grains不同，是在master上定义的，而且是针对minion定义的一些信息。像一些比较重要的数据（密码）能够存在pillar里，还能够定义变量等

加载saltstack配置文件中的pillar

在master主机（ying01）修改/etc/salt/master文件，加载pillar配置

[root@ying01 ~]# vim /etc/salt/master

#pillar_roots:            //去掉#号
#  base:                  //去掉#号
#    - /srv/pillar        //去掉#号

重启salt-master服务，建立在配置文件（master文件）定义的目录。

[root@ying01 ~]# systemctl restart salt-master

[root@ying01 ~]# mkdir /srv/pillar

自定义配置自定义pillar

切换到此目录下，建立子配置test.sls文件，这个文件salt不会直接加载须要建立，引导文件

[root@ying01 ~]# cd /srv/pillar
[root@ying01 pillar]# vim test.sls  

conf: /etc/123.conf

建立引导文件top.sls

[root@ying01 pillar]# vim /srv/pillar/top.sls

base:
  'ying02'：           //在ying02机器下
    - test             //加载test配置

当更改完pillar配置文件后，咱们能够经过刷新pillar配置来获取新的pillar状态

[root@ying01 pillar]# salt '*' saltutil.refresh_pillar  //刷新
ying02:
    True
ying01:
    True
ying03:
    True
[root@ying01 pillar]# salt '*' pillar.item conf
ying02:
    ----------
    conf:
        /etc/123.conf           
ying01:
    ----------
    conf:
ying03:
    ----------
    conf:

top文件能够添加多个子配置文件

分别建立test2.sls 、test2.sls子配置文件

[root@ying01 pillar]# vim test2.sls 

zzz: /date/test2


[root@ying01 pillar]# vim test3.sls 

qqq: /tmp/test3

在把上面2个子配置文件，添加到top文件

[root@ying01 pillar]# vim top.sls 

base:
  'ying02':
    - test
    - test1
  'ying03':
    - test2
    - test3

查看项目 www、conf、zzz、qqq

[root@ying01 pillar]# salt '*' saltutil.refresh_pillar
ying02:
    True
ying03:
    True
ying01:
    True

[root@ying01 pillar]# salt  '*' pillar.item www conf zzz qqq
ying03:
    ----------
    conf:
    qqq:
        /tmp/test3
    www:
    zzz:
        /date/test2
ying02:
    ----------
    conf:
        /etc/123.conf
    qqq:
    www:
        /date/123
    zzz:
ying01:
    ----------
    conf:
    qqq:
    www:
    zzz:

能够把多个子配置文件写在一个子配置里

好比在test4中，建立3个项目，至关于包含3个子配置文件

[root@ying01 pillar]# vim test4.sls 

AAA: /tmp/test3
BBB: /tmp/ok
CCC: /tmp/nba

[root@ying01 pillar]# vim top.sls         //把test4添加到引导文件top.sls中

base:
  'ying02':
    - test
    - test1
  'ying03':
    - test2
    - test3
  'ying01':
    - test4

刷新测试，test4中项目都会列出来

[root@ying01 pillar]# salt '*' saltutil.refresh_pillar      //刷新配置文件


[root@ying01 pillar]# salt  '*' pillar.item AAA BBB CCC
ying01:
    ----------
    AAA:
        /tmp/test3
    BBB:
        /tmp/ok
    CCC:
        /tmp/nba
ying03:
    ----------
    AAA:
    BBB:
    CCC:
ying02:
    ----------
    AAA:
    BBB:
    CCC:

7、saltstack安装配置httpd

在master主机（ying01）修改/etc/salt/master文件，加file_roots配置

[root@ying01 ~]# vim /etc/salt/master 


# file_roots:             //去掉#号
#   base:                 //去掉#号，前面2个空格
#     - /srv/salt/        //去掉#号，前面4个空格

重启salt-master服务，建立在配置文件（master文件）定义的目录。

[root@ying01 ~]# systemctl restart salt-master
[root@ying01 ~]# mkdir  /srv/salt
[root@ying01 ~]# cd /srv/salt/

建立top引导文件，意思是在全部主机上加载httpd模块

[root@ying01 salt]# vim /srv/salt/top.sls

base:
  '*':              //星号，表明全部认证主机
    - httpd         //加载httpd模块

新建httpd模块配置文件

[root@ying01 salt]# vim httpd.sls

httpd-service:          //id的名称，能够自定义
  pkg.installed:        //包安装函数
    - names:            //加载服务名称； 若是要安装一个服务，写成： -names: httpd 不用换行
      - httpd           //要加载的服务1
      - httpd-devel     //要加载的服务2
  service.running:      //来保证指定的服务启动的函数
    - name: httpd       //启动服务的名称是 httpd
    - enable: True      //ture 表示开机启动，

查看3台机器是否安装httpd服务；系统服务都在这个目录下：/lib/systemd/system

[root@ying01 salt]# ls /lib/systemd/system |grep httpd       //ying01机器httpd服务
httpd.service

[root@ying02 ~]# ls /lib/systemd/system |grep httpd         //ying02上没有此服务

[root@ying03 ~]# ls /lib/systemd/system |grep httpd         //ying02上没有此服务

在ying01上给ying02安装httpd服务

[root@ying01 salt]# salt-key   //认证的主机
Accepted Keys:
ying01
ying02
ying03
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@ying01 salt]# salt 'ying02' state.highstate  //state.highstate会加载/srv/salt/top.sls中模块

在执行 salt 'aming-02' state.highstate 执行过程会比较慢，由于ying02客户端上在yum install httpd httpd-devel；在master执行命令的时候，机器会在后台安装，此时到ying02上能够看到yum、httpd进程，说明httpd服务正在经过mater机器

[root@ying02 ~]# ps aux |grep yum
root     26256  2.5  1.5 328292 28268 ?        Sl   10:45   0:00 /usr/bin/python /usr/bin/yum --quiet --assumeyes check-update --setopt=autocheck_running_kernel=false

[root@ying02 ~]# ps aux |grep yum
root     26323 44.7  3.8 517040 71984 ?        S    10:46   0:01 /usr/bin/python /usr/bin/yum -y install httpd

[root@ying02 ~]# ps aux |grep httpd
root     26323  1.9  3.8 517068 72132 ?        S    10:46   0:01 /usr/bin/python /usr/bin/yum -y install httpd
root     26404  0.0  0.0 112720   984 pts/0    S+   10:47   0:00 grep --color=auto httpd

几分钟后，在master上出现执行结果反馈的信息

[root@ying01 salt]# salt 'ying02' state.highstate
ying02:

ERROR: Minions returned with non-zero exit code

从上面信息，能够看出 service.running 模块加载有问题，那说明是httpd启动有问题

到客户端ying02上，查看日志信息

[root@ying02 ~]# cat  /var/log/salt/minion |grep httpd
2018-09-09 10:50:24,722 [salt.loaded.int.module.cmdmod:753 ][ERROR   ][26156] Command '[u'systemd-run', u'--scope', u'systemctl', 'start', u'httpd.service']' failed with return code: 1
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

打开端口查看，咱们发现httpd启动所须要的80端口，被nginx占用，中止nginx服务

[root@ying02 ~]# /etc/init.d/nginx stop

[root@ying02 ~]# systemctl start httpd
[root@ying02 ~]# netstat -lnpt |grep httpd
tcp6       0      0 :::80                   :::*                    LISTEN      28117/httpd

OK，成功启动，说明在用salt远程安装的时候，应该把注意客户机已开启的服务对即将进行的安装，是否产生干涉；

再运行一次，检测

若是给全部认证主机安装，只须要把ying02改成*

[root@ying01 salt]# salt-key 
Accepted Keys:
ying01
ying02
ying03
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@ying01 salt]# salt '*' state.highstate

若是部分安装，那么就把不安装取消认证

[root@ying01 salt]# salt-key 
Accepted Keys:
ying02
ying03
Denied Keys:
Unaccepted Keys:
ying01
Rejected Keys:
[root@ying01 salt]# salt '*' state.highstate

注意：state.highstate会读取全部环境（包括base环境）的top.sls文件，而且执行top.sls文件内容里面定义的sls文件，不在top.sls文件里面记录的sls则不会被执行；

8、配置管理文件

建立test.sls文件，写入如下语句；

[root@ying01 salt]# pwd
/srv/salt
[root@ying01 salt]# vim test.sls

file_test:                              //配置文件名称，能够自定义
  file.managed:
    - name: /tmp/ying.com               //定义name属性
    - source: salt://test/123/1.txt     //定义来源目录，  salt：// == /srv/salt/（master配置文件里面设置） 
    - user: root                        //定义全部者属性
    - group: root                       //定义组属性
    - mode: 600                         //定义文件权限

file_test 的含义，把指定目录下1.txt文件，同步到ying.com这个文件；修改1.txt文件内容，ying.com文件内容和其保持一致；而且指定gid、uid，以及权限；

建立test.sls文件中，定义的目录、文件

[root@ying01 salt]# mkdir -p test/123/      //建立连级目录
[root@ying01 salt]# touch test/123/1.txt    //新建1.txt文件
[root@ying01 salt]# tree
.
├── httpd.sls
├── test
│   └── 123
│       └── 1.txt
├── test.sls
└── top.sls

2 directories, 4 files

编辑top.sls文件，定义运行环境以及须要运行sls

[root@ying01 salt]# vim top.sls

base:
  '*':
    - test

针对认证主机ying02 加载top文件

[root@ying01 salt]# salt 'ying02' state.highstate
ying02:

[root@ying02 ~]# ls -lt /tmp/ying.com
-rw------- 1 root root 9 9月   9 23:54 /tmp/ying.com
[root@ying02 ~]# cat /tmp/ying.com
AAAAAAAA

9、配置管理目录

继续建立test_dir.sls文件

[root@ying01 salt]# pwd
/srv/salt
[root@ying01 salt]# vim test_dir.sls  

file_dir:                       
  file.recurse:                          
    - name: /tmp/testdir       
    - source: salt://test/123     //同步123目录   
    - user: root
    - file_mode: 640              //文件权限
    - dir_mode: 750               //目录权限
    - mkdir: True                 //ture为自动建立目录
    - clean: True                 //master删除文件或者目录，客户端上也同样

编辑tops.sls文件，把test_dir模块写入；

[root@ying01 salt]# vim top.sls 

base:
  '*':
    - test
    - test_dir

针对认证主机ying02 加载top.sls文件

[root@ying01 salt]# salt 'ying02' state.highstate

到客户端ying02上查看，有/tmp/testdir目录生成，及其目录下1.txt生成

[root@ying02 ~]# ls -ld /tmp/testdir                  //目录权限为750
drwxr-x--- 2 root root 19 9月  10 19:29 /tmp/testdir

那么在master（ying01）上，在123目录下建立1个子目录456

[root@ying01 salt]# mkdir  test/123/456
[root@ying01 salt]# tree
.
├── httpd.sls

到客户端ying02上查看，在/tmp/testdir目录却没有456目录生成；

[root@ying02 ~]# tree /tmp/testdir/
/tmp/testdir/
├── 1.txt
└── 2.txt

0 directories, 2 files

注意：若是source对应的目录里有空目录（456）的话，客户端上不会建立该目录(456);

在master(ying01)机器上，在456目录下建立8.txt文件，使其目录不wei空；

[root@ying01 salt]# touch test/123/456/8.txt
[root@ying01 salt]# tree

[root@ying02 ~]# tree /tmp/testdir/
/tmp/testdir/
├── 1.txt
├── 2.txt
└── 456
    └── 8.txt

1 directory, 3 files

10、配置管理远程命令

[root@ying01 salt]# vim shell_test.sls

hell_test:
  cmd.script:
    - source: salt://test/1.sh
    - user: root

[root@ying01 salt]# vim test/1.sh

#!/bin/bash
touch /tmp/111.txt
if [ ! -d /tmp/1233 ]
then
    mkdir /tmp/1233
fi

[root@ying01 salt]# vim top.sls

[root@ying01 salt]# vim top.sls 

base:
  '*':
    - cron_test

11、配置管理计划任务

建立计划任务

定义cron_test.sls配置文件

[root@ying01 salt]# vim cron_test.sls

cron_test:
  cron.present:
    - name: /bin/touch /tmp/111.txt
    - user: root
    - minute: '*'
    - hour: 20
    - daymonth: '*'
    - month: '*'
    - dayweek: '*'

建立top.sls 引导文件

[root@ying01 salt]# vim top.sls 

base:
  '*':
    - cron_test

针对主机ying02，进行状态刷新

[root@ying01 salt]# salt 'ying02' state.highstate
ying02:
----------
          ID: cron_test
    Function: cron.present
        Name: /bin/touch /tmp/111.txt
      Result: True
     Comment: Cron /bin/touch /tmp/111.txt added to root's crontab
     Started: 21:37:39.312465
    Duration: 297.174 ms
     Changes:   
              ----------
              root:
                  /bin/touch /tmp/111.txt

Summary for ying02
------------
Succeeded: 1 (changed=1)

------------
Total states run:     1
Total run time: 297.174 ms

在主机ying02上，查看计划任务

[root@ying02 ~]# crontab -l
# Lines below here are managed by Salt, do not edit
# SALT_CRON_IDENTIFIER:/bin/touch /tmp/111.txt
* 20 * * * /bin/touch /tmp/111.txt

编辑 cron_test.sls配置文件，把minute 改成58分

[root@ying01 salt]# vim cron_test.sls

cron_test:
  cron.present:
    - name: /bin/touch /tmp/111.txt
    - user: root
    - minute: '58'          //修改此计划
    - hour: 20
    - daymonth: '*'
    - month: '*'
    - dayweek: '*'

再次对ying02刷新状态

[root@ying01 salt]# salt 'ying02' state.highstate
ying02:
----------
          ID: cron_test
    Function: cron.present
        Name: /bin/touch /tmp/111.txt
      Result: True
     Comment: Cron /bin/touch /tmp/111.txt updated

在主机ying02上，查看计划任务，发现计划任务更改，试验成功

[root@ying02 ~]# crontab -l

# Lines below here are managed by Salt, do not edit
# SALT_CRON_IDENTIFIER:/bin/touch /tmp/111.txt
58 20 * * * /bin/touch /tmp/111.txt

删除此计划

把配置文件中 cron.present: 改成 cron.absent: 表示取消任务

[root@ying01 salt]# vim cron_test.sls

cron_test:
  cron.absent:
    - name: /bin/touch /tmp/111.txt

刷新状态

[root@ying01 salt]# salt 'ying02' state.highstate
ying02:
----------
          ID: cron_test
    Function: cron.absent
        Name: /bin/touch /tmp/111.txt
      Result: True
     Comment: Cron /bin/touch /tmp/111.txt removed from root's crontab

    Duration: 167.855 ms
     Changes:   
              ----------
              root:

------------
Succeeded: 1 (changed=1)
Failed:    0
------------
Total states run:     1
Total run time: 167.855 ms

此时在ying02上，查看计划任务列表，已经为空，说明计划列表删除

[root@ying02 ~]# crontab -l
# Lines below here are managed by Salt, do not edit
[root@ying02 ~]#

12、 saltstack – 其它经常使用命令

拷贝master上的文件到客户端：cp.get_file

[root@ying01 salt]# salt  -L 'ying02,ying03' cp.get_file salt://test/123/1.txt  /tmp/aaa.txt
ying02:
    /tmp/aaa.txt
ying03:
    /tmp/aaa.txt

在客户端ying0一、ying02上查看复制的结果；

[root@ying02 ~]# ls -l /tmp/aaa.txt 
-rw-r--r-- 1 root root 9 9月  11 12:03 /tmp/aaa.txt

[root@ying03 ~]# ls -l /tmp/aaa.txt 
-rw-r--r-- 1 root root 9 9月  11 12:03 /tmp/aaa.txt

拷贝master上的目录到客户端：cp.get_dir

[root@ying01 salt]# salt 'ying0[23]' cp.get_dir salt://test/123/ /tmp/
ying03:
    - /tmp//123/1.txt
    - /tmp//123/2.txt
    - /tmp//123/456/8.txt
ying02:
    - /tmp//123/1.txt
    - /tmp//123/2.txt
    - /tmp//123/456/8.txt

在客户端端查看复制结果

[root@ying02 ~]# ls  -la /tmp/123
总用量 12
drwxr-xr-x   3 root root   43 9月  11 12:13 .
drwxrwxrwt. 16 root root 4096 9月  11 12:13 ..
-rw-r--r--   1 root root    9 9月  11 12:13 1.txt
-rw-r--r--   1 root root    9 9月  11 12:13 2.txt
drwxr-xr-x   2 root root   19 9月  11 12:13 456

显示存活的minion

[root@ying01 salt]# salt-run manage.up
- ying01
- ying02
- ying03

批量执行脚本，命令行下执行master上的shell脚本

[root@ying01 salt]# salt '*' cmd.script salt://test/1.sh
ying02:
    ----------
    pid:
        19885
    retcode:
        0
    stderr:
    stdout:
ying03:
    ----------
    pid:
        4331
    retcode:
        0
    stderr:
    stdout:
ying01:
    ----------
    pid:
        34919
    retcode:
        0
    stderr:
    stdout:

十3、salt-ssh使用

salt-ssh不须要对客户端作认证，客户端也不用安装salt-minion，它相似pssh/expect

编辑roster文件，添加如下机器的内容

[root@ying01 salt]# vim  /etc/salt/roster 


ying01
   host: 192.168.112.136
   user: root
   passwd: ssss1234
ying02
   host: 192.168.112.138
   user: root
   passwd: ssss1234
ying03
   host: 192.168.112.139
   user: root
   passwd: ssss1234

第一次执行的时候会自动把本机的公钥放到对方机器上，而后就能够把roster里面的密码去掉

[root@ying01 salt]# salt-ssh --key-deploy '*' -r 'w' 
ying03:
    ----------
    retcode:
        0
    stderr:
    stdout:

删除登陆密码

如今再编辑roster文件，把个机器的密码取消；

[root@ying01 salt]# vim  /etc/salt/roster      

ying01:
   host: 192.168.112.136
   user: root
ying02:
   host: 192.168.112.138
   user: root
ying03:
   host: 192.168.112.139
   user: root
~

再执行命令，可以成功，说明公钥已经推送到各个客户端上

[root@ying01 salt]# salt-ssh --key-deploy '*' -r 'w'
