ansible用roles的方式安装5.0版zabbix-agent2

安装zabbix-agent2

1.主机清单文件（必须先和目标主机免密）2.创建角色目录3.编写具体任务4.编写触发任务（重启服务）5.templates放置模板文件(必须以.j2结尾)6.编写变量文件7.编写调用任务文件（名字任意起，但必须是yml）8.执行roles

[root@zabbix-server roles]# tree -L 2
.
├── ansible.cfg               
├── group_vars      #变量目录
│   └── all
├── hosts           #主机清单
├── site.yml 
└── zabbix-agent2   #角色名称
    ├── files       #存放文件
    ├── handlers    #触发任务
    ├── tasks       #具体任务
    └── templates   #模板文件

[root@zabbix-server roles]# cat hosts
[webservers]
node1

这里我做了用主机名的方式登录：看管理机用主机名登录文章

mkdir -p zabbix-agent2{tasks,handlers,templates.files}

#编写思路
1.安装
2.配置
3.启动

[root@zabbix-server roles]# cat zabbix-agent2/tasks/main.yaml 
- name: Add repository
  yum_repository:
    name: zabbix
    description: Zabbix YUM repo
    baseurl: https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64

- name: Installed Zabbix-Agent2 Server
  yum:
    name: zabbix-agent2 
    state: present

- name: Configure Zabbix-Agent2 Server
  template:
    src: zabbix_agent2.conf.j2
    dest: /etc/zabbix/zabbix_agent2.conf
  notify: Systemd Restart Zabbix-agent2

    - { src: './zabbix_agent2.d/nginx_status.conf', dest: '/etc/zabbix/zabbix_agent2.d/' }

  with_items:

- name: System Zabbix-Agent2 Server
  systemd:
    name: zabbix-agent2
    state: started
    enabled: yes

[root@zabbix-server roles]# cat zabbix-agent2/handlers/main.yml 
#重启服务
- name: Systemd Restart Zabbix-agent2
  systemd:
    name: zabbix-agent2
    state: restarted

templates中放带有变量的文件，会自己解析

[root@zabbix-server roles]# cat zabbix-agent2/templates/zabbix_agent2.conf.j2 
PidFile=/var/run/zabbix/zabbix_agent2.pid
LogFile=/var/log/zabbix/zabbix_agent2.log
LogFileSize=0
Server={{ zabbix_server_ip }}
ServerActive={{ zabbix_server_ip }}
Hostname={{ ansible_hostname }}
Hostmetadata=master
Include=/etc/zabbix/zabbix_agent2.d/*.conf
ControlSocket=/tmp/agent.sock

#有变量的都可以写在这里面
[root@zabbix-server roles]# cat group_vars/all 
##zabbix-server
zabbix_server_ip: 192.168.10.68

[root@zabbix-server roles]# cat site.yml 
- hosts: webservers
  roles:
     - zabbix-agent2

[root@zabbix-server roles]# ansible-playbook site.yml  -i hosts
