centos7 ansible yum安装web软件

1、网站拓扑

ansible主机inventory的状况：

# cat ansible_inventory.txt 

[front]

10.11.7.224 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=xuAK

10.11.5.209 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=pwByh

[redmon]

10.11.7.205 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WlkW

10.11.7.202 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=iJMfZ

10.11.7.201 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WxB6

[web]

10.11.7.207 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=VtxR3

10.11.7.206 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=adR5I

10.11.7.192 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=W5f4

[db]

10.11.7.200 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=vLmb

10.11.7.195 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WOg

10.11.7.193 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=fZrLv

2、安装部分

一、准备所需的源

下面是nginx源为例，具体参考博客centos7配置更新源、epel源

# cat /etc/yum.repos.d/ngx.repo

# filename: nginx.repo

[nginx]

name=centos7 nginx repo

baseurl=http://nginx.org/packages/centos/7/$basearch/

enabled=1

gpgcheck=0

#rpm -ivhhttps://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

二、准备好所需的安装包（建议下载后，经过拷贝等方式进行安装，有部分关联包，根据安装过程当中，出现的提示安装便可）

下载包：（nginx为例，部分使用系统默认自带的安装包）

# yum install --downloadonly --downloaddir=/root/ans/ningx/ nginx

keepalived包使用默认

或者使用yumdownloader下载：

# yumdownloader --resolve --destdir=/root/ans/ openssl-devel

# ls     #安装包

ansible_inventory.txt   mongodb  mysql  nginx  redis  resin

三、ansible安装各个功能应用程序

经过ansible对不一样功能的服务器进行安装，具体以下（ntp时间同步能够略过）

3.一、安装开发工具：

# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "yum groupinstall 'Development Tools' -y"

3.二、ntp时间同步

# ansible all -i /root/ans/ansible_inventory.txt -m yum -a "name=ntp state=present"

# ansible all -i /root/ans/ansible_inventory.txt -m service -a "name=ntpd state=started enabled=yes"

# ansible all -i ansible_inventory.txt -m systemd -a "name=ntpd state=restarted enabled=yes"

# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "date"

#ansible all -i /root/ans/ansible_inventory.txt -m cron -a "name='sync cron' hour=4 user=root job='ntp.sjtu.edu.cn'"

定时的结果：

# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "crontab -l"

# crontab -l

#Ansible: sync cron

0 4 * * * ntp.sjtu.edu.cn

定时取消：

# ansible all -i /root/ans/ansible_inventory.txt -m cron -a "name='sync cron' minute=10 hour=4 user=root job='ntp.sjtu.edu.cn' state=absent"

新建文件夹，指定存放路径

http://www.iyunv.com/thread-211953-1-1.html

# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "mkdir /root/ans"

或

# ansible all -i /root/ans/ansible_inventory.txt -m file -a "path=/root/ans state=directory"

查看

# ansible all -i /root/ans/ansible_inventory.txt -a "ls -l /root"

3.三、安装nginx

[front][web]

# ansible front,web -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/nginx dest=/root/ans/"

# ansible front,web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ivh /root/ans/nginx/*"

# ansible front,web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ql nginx"

启动与中止

# ansible front,web -i /root/ans/ansible_inventory.txt -m systemd -a "name=nginx state=started enabled=yes"

# ansible front,web -i /root/ans/ansible_inventory.txt -m systemd -a "name=nginx state=stopped"

3.四、keepalived安装

[front]

# ansible front -i /root/ans/ansible_inventory.txt -m yum -a "name=keepalived state=latest"

# ansible front -i /root/ans/ansible_inventory.txt -m service -a "name=keepalived state=start enabled=yes“

# ansible front -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ql keepalived"

# ansible front -i /root/ans/ansible_inventory.txt -m systemd -a "name=keepalived state=started enabled=yes"

# ansible front -i /root/ans/ansible_inventory.txt -m shell -a "ps -ef | grep keepalived" --limit=10.11.7.224

3.五、安装resin：（须要安装关联包jdk、openssl-devel）

[web]

# ls resin/

jdk-8u121-linux-x64.rpm  resin-4.0.49-1.x86_64.rpm  RPM-GPG-KEY-caucho

# ansible web -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/resin dest=/root/ans/"

# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/resin/jdk-8u121-linux-x64.rpm -y”

# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "rpm --import /root/ans/resin/RPM-GPG-KEY-caucho"

# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "yum install openssl-devel -y"

# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ivh /root/ans/resin/resin-4.0.49-1.x86_64.rpm"      #也可用使用yum来安装

3.六、安装mongodb和Redis：

[redmon]

# ansible redmon -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/mongodb dest=/root/ans/"

# ansible redmon -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/redis dest=/root/ans/"

# ansible redmon -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/redis/*.rpm -y"

# ansible redmon -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/mongodb/*.rpm -y"

3.七、安装mysql（mysql-community-server）：

# ansible db -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/mysql dest=/root/ans/"

# ansible db -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/mysql/*.rpm -y"
