主要完成通过playbook自动生成zabbix_server,agent，这里没有完全实现自动化，这里机器的获取还是需要人为手工填写，如果感兴趣想通过自动获取需要部署的机器可以通过namp扫描工具awk命令截取，这里不过多描述。我用两台机器做的测试，老版本的模块用法会有差异，如果无法执行可以通过官网去查看https://ansible-tran.readthedocs.io/en/latest/,参考文档https://www.cnblogs.com/LyShark/p/10886486.html
ansible 2.4.2
zabbix 3.4.15
安装nmap扫描工具
yum install nmap -y #通过ping探测172.16.9.0网段中存活机器 nmap -sP 172.16.9.0/24
完成机器间的免密登录
生成公钥对
ssh-keygen -t rsa设置ansible hosts配置
[test] 172.16.9.141 ansible_ssh_user="root" ansible_ssh_pass="root" 172.16.9.142 ansible_ssh_user="root" ansible_ssh_pass="root" [zabbix_server] 172.16.9.141 [zabbix_client] 172.16.9.142批量推送公钥到集群节点
- hosts: test user: root tasks: - name: ssh-copy authorized_key: user=root key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}" tags: - sshkey报错:
FAILED! => {"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."}解决：
/etc/ansible/ansible.cfg
修改host_key_checking(默认是check的)
playbook构建zabbix_server(官方建议一个play写一个独立的任务，测试不过多计较了)

再来几个检查语法结构，主机是否生效的命令
ansible-playbook install_zabbix_server.yaml --syntax-check
ansible-playbook install_zabbix_server.yaml --list-task
ansible-playbook install_zabbix_server.yaml --list-hosts
