Ansible自动化运维----playbook部署zabbix
- 在
/home/devops/ansible/hosts对zabbix部署所需的主机进行设置
[devops@server10 ansible]$ cat hosts
[devops@server10 ansible]$ cd zabbix
[devops@server10 zabbix]$ ls
agent.yml db.yml my.cnf web.yml zabbix.conf
create.sql.gz deploy.yml server.yml zabbix_agentd.conf.j2 zabbix_server.conf
解释一下这些文件：
找一部主机安装mariadb，将my.cnf拷贝到当前目录下/home/devops/ansible/zabbix/
vim my.cnf
添加 character_set_server=utf8
- 找一个主机安装
zabbix，将其zabbix.conf文件拷贝过来
vim zabbix.conf
将文件中的地区进行修改
[devops@server10 zabbix]$ vim zabbix_agentd.conf.j2
- zabbix-server所在主机IP
zabbix-server所在主机IP
利用ansible_hostname自动获取
[devops@server10 zabbix]$ vim zabbix_server.conf

db部分
在此导入数据库的时候一定要注意，确保导入成功
具体请参见
！！该数据库已经经过初始化，所以有login_user 和 login_password

将以上部分整合到一个playbook中即deploy.yml
- 推送
[devops@server10 ansible]$ ansible-playbook zabbix/deploy.yml

执行的时候，一定要确保这一步有做，导入的时候可能会由于电脑性能原因导入较慢
结果：
[root@server12 web]# cat zabbix.conf.php
测试：能够成功连接
