集群运维自动化工具ansible之使用playbook安装zabbix客户端

 更新时间:2014年07月14日 16:33:24   投稿:hebedich  
Zabbix客户端的安装配置:Zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。zabbix能监视各种网络参数,保证服务器系统的安全运营;本文讲述的是使用playbook安装zabbix客户端。

之前介绍了关于ansible的安装与使用(包括模块与playbook使用,地址是https://www.jb51.net/article/52154.htm),今天介绍一下如何使用playbook来部署zabbix客户端。
ansible服务端的环境为centos 6.5 x86_64系统
ansible客户端环境为centos 6.3 x86_64系统
目前我的playbook只允许centos或redhat 6系列系统来安装zabbix客户端,并且客户端的版本是2.0.6.
下面是playbook的结构

14:29:30 # pwd

12 directories, 13 files

下面是先介绍一下安装方面zabbix_client_install的内容
1、galaxy_info的信息

14:32:15 # cat /etc/ansible/roles/zabbix_client_install/meta/main.yml 
galaxy_info:
 author: Deng Lei
 description: Install Zabbix Client 
 license: MIT
 min_ansible_version: 1.6
 platforms:
 - name: CentOS
  versions:
  - 6
 categories:
 - Monitor
dependencies: []

2、task里的copy.xml信息

14:33:35 # cat /etc/ansible/roles/zabbix_client_install/tasks/copy.yml 
 - name: Stop Exist Zabbix Client Service In Redhat Client
  shell: ps -ef|grep zabbix|grep -v grep|awk '{print $2}'|xargs kill -9 >>/dev/null 2>&1
  ignore_errors: yes
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Delete Exist Zabbix Client Dir In Redhat Client
  shell: rm -rf {{ zabbix_dir }}/zabbix
  ignore_errors: yes
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Install Base Require Software In Redhat Client
  yum: name={{ item }} state=latest
  with_items:
   - telnet
   - dmidecode
   - tar
 - name: Create Zabbix User In Redhat Client
  user: name={{ zabbix_user }} state=present createhome=no shell=/sbin/nologin
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Copy Zabbix Client Software To Redhat Client
  copy: src=zabbix-{{ zabbix_version }}.tar.gz dest=/tmp/zabbix-{{ zabbix_version }}.tar.gz owner=root group=root
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Uncompression Zabbix Client Software To Redhat Client
  shell: tar zxf /tmp/zabbix-{{ zabbix_version }}.tar.gz -C {{ zabbix_dir }}/
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Copy Zabbix Start Script To Redhat Client
  template: src=zabbix_agentd dest=/etc/init.d/zabbix_agentd owner=root group=root mode=0755
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Copy Zabbix Config To Redhat Client
  template: src=zabbix_agentd.conf dest={{ zabbix_dir }}/zabbix/conf/zabbix_agentd.conf owner={{ zabbix_user }} group={{ zabbix_user }} mode=0644
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是复制对应的文件到客户端

3、task的install.yml信息

14:34:26 # cat /etc/ansible/roles/zabbix_client_install/tasks/install.yml 
 - name: Modify Zabbix Dir Permission In Redhat Client
  file: path={{ zabbix_dir }}/zabbix owner={{ zabbix_user }} group={{ zabbix_user }} mode=0755
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Check Zabbix User Sudo Permission In Redhat Client
  shell: grep "{{ zabbix_user }}" /etc/sudoers|wc -l
  register: zabbix_sudoer
  ignore_errors: True
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Give Sudo Permission To Zabbix User In Redhat Client
  shell: echo "{{ zabbix_user }} ALL=(root) NOPASSWD:/bin/netstat, /usr/bin/omreport" >> /etc/sudoers
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 and zabbix_sudoer|int ==0
 - name: Start Zabbix Service In Redhat Client
  shell: /etc/init.d/zabbix_agentd start
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6
 - name: Add Boot Start Zabbix Service In Redhat Client
  shell: chkconfig --level 345 zabbix_agentd on
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件主要是安装

4、tasks的delete.yml信息

14:35:08 # cat /etc/ansible/roles/zabbix_client_install/tasks/delete.yml 
 - name: Delete Zabbix compression Software In Redhat Client
  shell: rm -rf /tmp/zabbix-{{ zabbix_version }}.tar.gz
  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是安装完成后,删除安装前的文件

5、tasks的mail.yml

14:35:37 # cat /etc/ansible/roles/zabbix_client_install/tasks/main.yml 
- include: copy.yml
- include: install.yml
- include: delete.yml

此文件是允许运行哪个文件

6、templates的zabbix_agentd

15:15:45 # cat /etc/ansible/roles/zabbix_client_install/templates/zabbix_agentd
#!/bin/bash
#
# chkconfig: - 85 15
# description: Zabbix client script.
# processname: Zabbix
. /etc/profile 
SERVICE="Zabbix agent"
DAEMON={{ zabbix_dir }}/zabbix/sbin/zabbix_agentd
PIDFILE=/tmp/zabbix_agentd.pid
CONFIG={{ zabbix_dir }}/zabbix/conf/zabbix_agentd.conf
zabbix_agent_status=`ps aux|grep zabbix_agentd.conf|grep -v grep|wc -l`
zabbix_agent_pid=`ps aux|grep zabbix_agentd|grep -v grep|awk 'NR==1{print $2}'`
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
function check()
{
if [ $? -eq 0 ];then
  action $"Operating is:" /bin/true
else
  action $"Operating is:" /bin/false
fi
}
case $1 in
 'start')
  if [ -x ${DAEMON} ]
  then
   $DAEMON -c $CONFIG
   # Error checking here would be good...
   echo "${SERVICE} started."
  else
   echo "Can't find file ${DAEMON}."
   echo "${SERVICE} NOT started."
  fi
  check
 ;;
 
 'stop')
  if [ -s ${PIDFILE} ]
  then
   if kill `cat ${PIDFILE}` >/dev/null 2>&1
   then
    echo "${SERVICE} terminated."
    rm -f ${PIDFILE}
   fi
  fi
  check
 ;;
 'restart')
  /bin/bash $0 stop
  sleep 5
  /bin/bash $0 start
 ;;
 
 'status')
  if [ $zabbix_agent_status -ne 0 ];then
    echo "Zabbix Agentd is running ($zabbix_agent_pid)"
  else
    echo "Zabbix Agentd is not running!"
  fi
  ;;
 
*)
  echo "Usage: $0 {start|stop|status|restart}"
;;
 
esac
exit 0

这个文件是启动客户端的脚本

此文件是客户端的配置文件
8、vars的main.yml

15:17:06 # cat /etc/ansible/roles/zabbix_client_install/vars/main.yml 
zabbix_dir: /usr/local      客户端安全目录
zabbix_version: 2.0.6      客户端软件版本
zabbix_user: zabbix       客户端用户
zabbix_port: 10050        客户端的端口
zabbix_server_ip: 192.168.1.10  zabbix_server的ip

此文件是配置变量的

9、ansible安装zabbix客户端的playbook配置文件zabbix_client_install.yml

15:20:02 # cat /etc/ansible/zabbix_client_install.yml 
---
- hosts: "{{host}}"
 remote_user: "{{user}}"
 gather_facts: True
 roles:

10、使用playbook安装zabbix客户端

我的测试客户端环境是centos 6.3,ip是192.168.240.17,使用key登陆

15:22:01 # cd /etc/ansible/

可以看到39秒就安装完成,主要花费时间比较长的地方是fact收集、yum安装、文件传输。

可以看到安装后的客户端,完全是按照我的要求来做的。

12、删除已经安装的客户端
