——–hosts配置———-
[root@ansible_master roles]# vim ../hosts

[zabbix-agent]
192.168.142.102 hostname=ansible_02  #给后面参数进行调用
192.168.142.103 hostname=ansible_03
192.168.142.104 hostname=ansible_04

 

├── zabbix-agent
│   ├── handlers
│   │   └── main.yaml
│   └── tasks
│       └── main.yaml
└── zabbix-agent.yaml   #这个是引用文件,放置在roles目录,运行这个文件即可.

————思路——————

rpm -i http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
yum install zabbix-agent

vim /etc/zabbix/zabbix_agentd.conf
Server=127.0.0.1        改成Server=172.16.9.54
ServerActive=127.0.0.1  改成ServerActive=172.16.9.54
Hostname=Zabbix server  改成Hostname={hostname}   此处进行调用

——zabbix-agent.yaml  配置———
vim zabbix-agent.yaml

– hosts: zabbix-agent
  remote_user: root
  roles:
  – zabbix-agent

 

——-tasks配置脚本———-
vim zabbix-agent/tasks/main.yaml

– name: add iptables
  shell: iptables -I  INPUT 1 -p tcp –dport 10050 -j ACCEPT
– name: save iptables
  shell: service iptables save
– name: rpm i
#  shell: rpm -i http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
  yum: name=http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
– name: yum zabbix-agent
  #yum: name=zabbix-agent state=latest enable=yes
  yum: name=zabbix-agent state=latest
– name: enable service
  shell: systemctl enable zabbix-agent  #或使用 service: name=zabbix-agent enable=true
#  shell: yum install -y zabbix-agent
– name: change server ip
  shell: sed -i ‘s/Server=127.0.0.1/Server=172.16.9.54/g’ /etc/zabbix/zabbix_agentd.conf
– name: change server active ip
  shell: sed -i ‘s/ServerActive=127.0.0.1/ServerActive=172.16.9.54/g’ /etc/zabbix/zabbix_agentd.conf
– name: change server hostname
  shell: sed -i ‘s/Hostname=Zabbix server/Hostname={{hostname}}/g’ /etc/zabbix/zabbix_agentd.conf
  notify :
      – restart zabbix-agent

 

————-handlers脚本—————-

[root@ansible_master roles]# vim zabbix-agent/handlers/main.yaml

– name: restart zabbix-agent
  shell: systemctl restart zabbix-agent

——–正确的执行结果
[root@ansible_master roles]# ansible-playbook zabbix-agent.yaml -v
