运维监控系统之Open-Falcon

 

1、Open-Falcon介绍

一、监控系统，能够从运营级别（基本配置便可），以及应用级别（二次开发，经过端口进行日志上报），对服务器、操做系统、中间件、应用进行全面的监控，及报警，对咱们的系统正常运行的做用很是重要。html

二、基础监控前端

CPU、Load、内存、磁盘、IO、网络相关、内核参数、ss 统计输出、端口采集、核心服务的进程存活信息采集、关键业务进程资源消耗、NTP offset采集、DNS解析采集，这些指标，都是open-falcon的agent组件直接支持的。java

Linux运维基础采集项：http://book.open-falcon.org/zh/faq/linux-metrics.htmlpython

对于这些基础监控选项所有理解透彻的时刻，也就是对Linux运行原理及命令进阶的时刻。mysql

三、第三方监控linux

术业有专攻，运行在OS上的应用甚多，Open-Falcon的开发团队不可能把全部的第三方应用的监控所有作完，这个就须要开源社区提供更多的插件，当前对于不少经常使用的第三方应用都有相关插件了。ios

四、JVM监控git

对于Java做为主要开发语言的大多数公司，对于JVM的监控不可或缺。github

每一个JVM应用的参数，好比GC、类加载、JVM内存、进程、线程，均可以上报给Falcon，而这些参数的得到，均可以经过MxBeans实现。golang

使用 Java 平台管理 bean：http://www.ibm.com/developerworks/cn/java/j-mxbeans/

五、业务应用监控

对于业务须要监控的接口，好比响应时间等。能够根据业务的须要，上报相关数据到Falcon，并经过Falcon查看结果。

2、Zabbix、Nagios、Open-Falcon这3大开源运维监控工具的比较

 

3、Open-Falcon编写的整个脑洞历程

说明：Open-Falcon部署分为前端（客户端）和后端（服务端）

4、后端部署（服务端）

参考官方文档：https://book.open-falcon.org/zh_0_2/quick_install/prepare.html

一、系统环境

[root@ open -falcon-server ~] # cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

二、系统优化

#安装下载软件
yum install  wget -y
 
#更换aliyun源
mv  /etc/yum .repos.d /CentOS-Base .repo /etc/yum .repos.d /CentOS-Base .repo.backup
wget -O /etc/yum .repos.d /CentOS-Base .repo http: //mirrors .aliyun.com /repo/Centos-7 .repo
 
#下载epel源
yum install  epel-release.noarch -y
rpm -Uvh http: //mirrors .aliyun.com /epel/epel-release-latest-7 .noarch.rpm
yum clean all
yum makecache
 
#下载经常使用软件
yum install  git telnet net-tools tree nmap sysstat lrzsz dos2unix tcpdump ntpdate -y
 
#配置时间同步
ntpdate cn.pool.ntp.org
 
#更改主机名
hostnamectl set - hostname  open -falcon-server
hostname  open -falcon-server
 
#开启缓存
sed  -i 's#keepcache=0#keepcache=1#g'  /etc/yum .conf
grep  keepcache /etc/yum .conf
 
#关闭selinux
sed  -i 's/SELINUX=enforcing/SELINUX=disabled/g'  /etc/selinux/config
setenforce 0
 
#关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service

三、软件环境准备

#安装 redis

1
yum  install  redis -y

#redis经常使用命令

redis-server     redis 服务端
 
redis-cli　　　　redis 命令行客户端
 
redis-benchmark  redis 性能测试工具
 
redis-check-aof 　　AOF文件修复工具
 
redis-check-dump  RDB文件修复工具
 
redis-sentinel 　　  Sentinel 服务端

四、初始化MySQL表结构（备注：导入表结构后，注意检查）

cd  /tmp/  && git clone https: //github .com /open-falcon/falcon-plus .git
cd  /tmp/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql
rm  -rf /tmp/falcon-plus/

#设置数据库密码 (备注：用户名：root ,密码: password )

[root@ open -falcon-server open -falcon] # mysqladmin -uroot password "password"
Warning: Using a password on the command  line interface can be insecure.

#检查导入的数据库表

[root@ open -falcon-server open -falcon] # mysql -uroot -p
Enter password:

五、配置Go语言开发环境

#安装go语言开发包（备注：安装须要epel源）

1
yum  install  golang -y

#检查版本

[root@ open -falcon-server ~] # go version
  go version go1.8.3 linux /amd64

#查看go的安装路径

[root@ open -falcon-server ~] # find / -name go
/etc/alternatives/go
/var/lib/alternatives/go
/usr/bin/go
/usr/lib/golang/src/cmd/go   #须要的是这个路径
/usr/lib/golang/src/go
/usr/lib/golang/bin/go
/usr/lib/golang/pkg/linux_amd64/go

#设置环境变量GOROOT和GOPATH

export  GOROOT= /usr/lib/golang
export  GOPATH= /home

六、下载编译好的二进制版本

https://github.com/open-falcon/falcon-plus/releases

直接下载官方编译好的二进制版本(x86 64位平台)。

drwxrwxr-x. 5 501 501      40 Aug 15 19:16 transfer

七、修改配置文件cfg.json

坑：

部分模块依赖链接数据库，由于若是不修改配置文件，aggregator模块会出现没法启动，graph、hbs、nodata、api、alarm模块会出现开启不报错可是状态为开启失败的状况。

若是须要每一个模块都能正常启动，须要将上面模块的cfg.json的数据库信息进行修改。根据本教程的配置，须要修改配置文件所在的目录： 

模块 配置文件所在路径
aggregator    /home/work/aggregator/config/cfg.json
graph /home/work/graph/config/cfg.json
hbs /home/work/hbs/config/cfg.json
nodata /home/work/nodata/config/cfg.json
api /home/work/api/config/cfg.json
alarm /home/work/alarm/config/cfg.json

1）修改aggregator的配置文件

vim /home/work/aggregator/config/cfg.json

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

 

2）修改graph的配置文件

vim /home/work/graph/config/cfg.json

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

 

3）修改hbs的配置文件

vim /home/work/hbs/config/cfg.json

 

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

 

4）修改nodata的配置文件

vim /home/work/nodata/config/cfg.json

 

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

 

5）修改api的配置文件

vim /home/work/api/config/cfg.json

 

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

 

6）修改alarm的配置文件

vim /home/work/alarm/config/cfg.json

 

mysql的root密码为空，则去掉“password”，若不为空，则用root密码替换“password”。

#For debugging , You can check $WorkDir/$moduleName/log/logs/xxx.log

至此后端部署完成。

八、其它用法

#重载配置（备注：修改vi cfg.json配置文件后，能够用下面命令重载配置）

curl 127.0.0.1:1988 /config/reload

5、前端部署 （备注：在另一台服务器上面操做）

一、建立工做目录

export  HOME= /home/work
export  WORKSPACE=$HOME /open-falcon
mkdir  -p $WORKSPACE
cd  $WORKSPACE

二、克隆前端组件代码

git clone https: //github .com /open-falcon/dashboard .git

三、安装依赖包

yum install  -y python-virtualenv
yum install  -y python-devel
yum install  -y openldap-devel
yum install  -y mysql-devel
yum groupinstall "Development tools"  -y

坑：

#省略下面这三步不操做（备注：因执行virtualenv ./env；安装的pip版本为1.4.1，再用pip安装pip_requirements.txt文件中的软件。都会出现报错的状况，致使没法安装成功。主要缘由就是pip版本的问题。）解决这个问题，请参考第4步
#进入目录
cd  $WORKSPACE /dashboard/
virtualenv . /env
source  env /bin/activate #若是安装了高版本pip，请先卸载pip uninstall pip   再按两次y
#指定源安装包（备注：这步若是安装不成功，请检查pip版本是否为pip-9.0.1）
pip install  -r pip_requirements.txt -i

这里virtualenv ./env做用是建立一个新的python环境，详见：https://www.liaoxuefeng.com/wiki/0014316089557264a6b348958f449949df42a6d3a2e542c000/001432712108300322c61f256c74803b43bfd65c6f8d0d0000

source env/bin/activate会切换到这个环境下，以后进行pip安装：

./env/bin/pip install -r pip_requirements.txt -i https://pypi.douban.com/simple

 

四、先安装ez_setup.py,再安装pip

#下载ez_setup.py
wget --no-check-certificate https: //bootstrap .pypa.io /ez_setup .py
python ez_setup.py --insecure
 
#下载pip
wget https: //pypi .python.org /packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9 .0.1. tar .gz #md5=35f01da33009719497f01a4ba69d63c9
 
#解压并安装
tar  xf pip-9.0.1. tar .gz
cd  pip-9.0.1
python setup.py install
cd  ..

#配置环境变量  (备注：这步不须要操做了)

#查看pip路径
[root@prometheus dashboard] # which pip
/usr/bin/pip
 
#配置pip环境变量
[root@prometheus dashboard] # vi /etc/profile
#pip path
export  PATH= "/usr/bin/pip/bin:$PATH"
#使环境变量生效source /etc/profile
#测试是否可用
[root@prometheus dashboard] # pip

五、修改配置

#配置说明：

dashboard的配置文件为： 'rrd/config.py' ，请根据实际状况修改
 
## API_ADDR 表示后端api组件的地址
API_ADDR = "http://127.0.0.1:8080/api/v1"
 
## 根据实际状况，修改PORTAL_DB_*, 默认用户名为root，默认密码为""
## 根据实际状况，修改ALARM_DB_*, 默认用户名为root，默认密码为""

#修改方法

[root@Open-Falcon-client] #cd /home/work/open-falcon/dashboard/rrd
 
[root@Open-Falcon-client rrd] # cp config.py config.py.bak
 
( env )[root@Open-Falcon-client rrd] # vi config.py

 #启动服务

#启动服务
有两种方法：
法一：
( env )[root@Open-Falcon-client dashboard] # bash control start
falcon-dashboard started..., pid=40853
 
法二：
( env )[root@Open-Falcon-client dashboard] # ./control start
falcon-dashboard started..., pid=40853
 
#查看日志
( env )[root@Open-Falcon-client dashboard] # ./control tail

因为我使用的系统centos6.9中,python让我升级为2.7版本，安装gunicorn以后，运行./control start后依旧报错" I require gunicorn but it's not installed."

说明系统找不到gunicorn，这里将gunicorn的路径加入到$PATH中得以解决

[root@localhost ~]# find / -name gunicorn 
/usr/local/python2.7/lib/python2.7/site-packages/gunicorn
/usr/local/python2.7/bin/gunicorn
[root@localhost local]# export PATH=$PATH:/usr/local/python2.7/bin

 

#访问网站

http://192.168.1.181:8081

#关于登陆帐号的问题或参考FAQ

请自行注册管理员用户名和密码

#登陆界面

六、其它用法

#以开发者模式启动

. /env/bin/python  wsgi.py
 
open  http: //127 .0.0.1:8081 in  your browser.

#开启8081端口 （备注：若是关闭了防火墙，则直接忽略这步）

1）防火墙添加8081端口永久开放

firewall-cmd --add-port=8081/tcp --permanent

2）从新载入防火墙配置

firewall-cmd --reload

#中止dashboard运行

1
bash  control stop

#查看dashboard运行状态

1
bash  control status

 

6、FAQ

  • Q: open-falcon v0.2 有管理员账号吗？
  • A: 能够经过dashboard自行注册新用户，第一个用户名为root的账号会被认为是超级管理员，超级管理员能够设置其余用户为管理员。
  • Q: open-falcon v0.2 dashboard 能够禁止用户本身注册吗？
  • A: 能够的，在api组件的配置文件中，将signup_disable配置项修改成true，重启api便可。
