1 在zabbix-server机器上安装ansible

yum -y install ansible

2 将准备安装zabbix-agent的服务器写入ansible主机清单

vim /etc/ansible/hosts

[zabbix]
192.168.123.131  hostname=node1
192.168.123.137  hostname=node2
192.168.123.138  hostname=node3

注：其中hostname 是后面template模块会用到的hostname变量

3 创建部署所需要的role—zabbix-agent

cd /etc/ansible/roles
mkdir -pv zabbix-agent/{files,templates,tasks}

注：其中zabbix-agent下的三个文件夹都很重要，files下可以放zabbix-agent安装包或者yum源，templates放含有变量hostname的zabbix-agent配置文件

3.1 在files目录下，配置yum源（这个yum源直接用来配置zabbix-server也完全没问题的）

cd /etc/ansible/roles/zabbix-agent/files

[root@zabbix-server files]# vim zabbix.repo

[zabbix]
name=zabbix
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/
gpgcheck=0
enabled=1

[zabbix2]
name=zabbix frontend
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/frontend/
gpgcheck=0
enabled=1

3.2 在templates目录下，cp配置文件，设置变量。

server和server active都设置为zabbix-server的ip，hostname使用变量。cp的配置文件一定是j2结尾

cp /etc/zabbix/zabbix_agentd.conf  /etc/ansible/roles/zabbix-agent/templates/zabbix_agentd.conf.j2

在这里插入图片描述
注：配置文件中，上面三个位置需要修改

3.3 在tasks目录下，创建main.yml 文件

vim /etc/ansible/roles/zabbix-agent/tasks/main.yml

- name: get the zabbix-agent
  copy:
    src: zabbix.repo
    dest: /etc/yum.repos.d/
- name: install the zabbix-agent
  yum:
    name: zabbix-agent
    state: present
- name: copy the zabbix_agentd.conf
  template:
    src: zabbix_agentd.conf.j2
    dest: /etc/zabbix/zabbix_agentd.conf
- name: start zabbix-agent
  service:
    name: zabbix-agent
    state: started
    enabled: true

注： zabbix-agent目录下可以直接调用，所以无需写明templates和files的绝对路径

4 给其他节点服务器做免密

ssh-keygen

然后按三次回车键，会显示密钥创建成功，如下所示

Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

ssh-copy-id root@192.168.123.131
ssh-copy-id root@192.168.123.137
ssh-copy-id root@192.168.123.138

以上三台密钥设置成功

5 配置一个playbook，我直接在root下创建的

vim zabbix-agent.yml

---
- name: zabbix_install
  hosts: zabbix
  roles:
  - zabbix-agent

6 执行剧本，ansible部署zabbix-agent完成

ansible-playbook zabbix-agent.yml

执行完成
