ansible部署zabbix集群

1.基础操作：

• 配置hosts文件和repo源

[root@ansible ansible]# cat hosts 
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6


172.25.253.11 zabbix-server  
172.25.253.20 zabbix-agent 
[root@ansible ansible]# cat local.repo 
[centos]
name=centos
baseurl=http://172.25.253.144/file/repo/centos/
gpgcheck=0

[zabbix]
name=zabbix
baseurl=http://172.25.253.144/file/repo/zabbix/
gpgcheck=0

2.配置templates

• 配置zabbix.conf.j2

• 配置zabbix_server.conf.j2

• 配置zabbix_agentd.conf.j2

[root@ansible templates]# cat zabbix.conf.j2 
···
   <IfModule mod_php5.c>
        php_value max_execution_time 300
        php_value memory_limit 128M
        php_value post_max_size 16M
        php_value upload_max_filesize 2M
        php_value max_input_time 300
        php_value max_input_vars 10000
        php_value always_populate_raw_post_data -1
        php_value date.timezone Asia/Shanghai   #添加该行
    </IfModule>
    
    
[root@ansible templates]# grep -n '^'[a-Z] zabbix_server.conf.j2 
38:LogFile=/var/log/zabbix/zabbix_server.log
49:LogFileSize=0
72:PidFile=/var/run/zabbix/zabbix_server.pid
82:SocketDir=/var/run/zabbix
92:DBHost=localhost 						#取消改行注释
100:DBName=zabbix					
116:DBUser=zabbix
125:DBPassword=zabbix 						#取消改行注释
131:DBSocket=/var/lib/mysql/mysql.sock		#修改mysql的路径
329:SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
446:Timeout=4
488:AlertScriptsPath=/usr/lib/zabbix/alertscripts
498:ExternalScripts=/usr/lib/zabbix/externalscripts
534:LogSlowQueries=3000

[root@ansible templates]# grep -n '^'[a-Z] zabbix_agentd.conf.j2 
13:PidFile=/var/run/zabbix/zabbix_agentd.pid
32:LogFile=/var/log/zabbix/zabbix_agentd.log
43:LogFileSize=0
97:Server={{ serverip }}					#添加server的IP
138:ServerActive={{ serverip }}				#添加server的IP
149:Hostname=Zabbix-agent 					#添加Server的主机名
267:Include=/etc/zabbix/zabbix_agentd.d/*.conf

3.编写playbook

• 编写两个清单

• 第一个清单是作为server的zabbix安装和配置

• 第二个清单是作为agent的zabbix安装

[root@ansible ansible]# cat install_zabbix.yaml 
- name: First  tasks 
  hosts: zabbix_server 
  remote_user: root 

  tasks: 
  - name: cp hosts 
    copy: src=hosts  dest=/etc/hosts 
  - name: shell 
    shell: rm -rf /etc/yum.repos.d/* 
  - name: cp local.repo 
    copy: src=local.repo  dest=/etc/yum.repos.d/local.repo 
  - name: install zabbix 
    yum: 
      name: 
        - httpd 
        - mariadb
        - mariadb-server 
        - zabbix-server-mysql 
        - zabbix-web-mysql 
        - zabbix-agent 
        - zabbix-server 
  - name: start httpd service 
    service:  name=httpd state=started 
  - name: start mariadb service 
    service: name=mariadb state=started 
  - name: create  database 
    shell: mysql -uroot -e 'create database zabbix character set utf8 collate utf8_bin;'
  - name: grant all % 
    shell:  mysql -uroot -e "grant all privileges on zabbix.* to zabbix@'%' identified by 'zabbix';"
  - name: grant all localhost 
    shell:  mysql -uroot -e "grant all privileges on zabbix.* to zabbix@'localhost' identified by 'zabbix';"
  - name: add sql 
    shell: zcat /usr/share/doc/zabbix-server-mysql-3.4.15/create.sql.gz | mysql -uroot  zabbix 
  - name:  change PRC
    shell: sed -i '/date.timezone =/a\date.timezone = PRC' /etc/php.ini
  - name: change date 
    template: src=templates/zabbix.conf.j2 dest=/etc/httpd/conf.d/zabbix.conf
  - name: restart  httpd 
    shell: systemctl restart httpd 
  - name: copy 
    template: src=templates/zabbix_server.conf.j2 dest=/etc/zabbix/zabbix_server.conf 
  - name: start zabbix 
    service: name=zabbix-server state=started 


- name: Two First 
  hosts: zabbix_agent 
  remote_user: root 

  tasks: 
  - name: cp hosts
    copy: src=hosts  dest=/etc/hosts
  - name: shell
    shell: rm -rf /etc/yum.repos.d/*
  - name: cp local.repo
    copy: src=local.repo  dest=/etc/yum.repos.d/local.repo
  - name: install zabbix
    yum: name=zabbix-agent state=latest 
  - name: change config 
    template: src=templates/zabbix_agentd.conf.j2 dest=/etc/zabbix/zabbix_agentd.conf 
  - name: restart service 
    service: name=zabbix-agent state=started 

4.执行playbook

[root@ansible ansible]# ansible-playbook install_zabbix.yaml 

PLAY [First  tasks] *****************************************************************************************************************************************

TASK [Gathering Facts] **************************************************************************************************************************************
ok: [172.25.253.11]

TASK [cp hosts] *********************************************************************************************************************************************
ok: [172.25.253.11]
·
·
·
PLAY RECAP **************************************************************************************************************************************
172.25.253.138             : ok=10   changed=5    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0   
172.25.253.139             : ok=10   changed=5    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0   
172.25.253.140             : ok=10   changed=5    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0   

5.检查zabbix的端口

[root@ansible ansible]# ansible all -m shell -a "ss -ntpl | grep 10051 "    
172.25.253.20 | FAILED | rc=1 >>
non-zero return code
