自定义监控
自定义监控MySQL主从状态
- 安装MySQL
- 配置主从并验证是否能成功同步
- 写脚本获取从库的状态，确保2个yes，如果不是两个也是就报错
- 配置/usr/local/etc/zabbix_agentd.conf 文件自定义监控
- 重启zabbix_agentd
- 在从库本地执行脚本看结果是否正常匹配
- 去zabbix_server 端用zabbix_get 名令手动获取下的状态并且确保状态与从库手动执行结果时一致
- 配置web 界面添加监控项与触发器
- 手动触发(把主库MySQL服务停掉) 并验证是否报警
监控是在从库上

环境准备
| 主机 | ip | 主机名 | 系统版本 | MySQL版本 |
|---|---|---|---|---|
| zabbix_server服务端 | 192.168.229.145 | node1 | centos8/redhat8 | |
| 从库 | 192.168.229.130 | node2 | centos8/redhat8 | MySQL5.7 |

1.1.1配置MySQL主从
注意：配置MySQL主从需要两边数据库一样。因为是刚创建的数据库所有两边的数据库一样。
如果主库有数据库从库没有数据库，把主库数据库全备。使用scp传到从库里再恢复到从库里面。
如果不清楚看我这篇文章： http://t.csdn.cn/SGcqn
1.1.2在主数据库里创建一个同步账号授权给从数据库使用
# 在MySQL版本5.7里在你授权给这个用户的时候，用户不存在会自动创建，但是在8.0里不行。
[root@node3 ~]# mysql -uroot -pruntime123!
# 授权
mysql> grant replication slave on *.* to 'tom'@'192.168.229.130' identified by
'tom123!';
Query OK, 0 rows affected, 1 warning (0.00 sec)
# 刷新授权表
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
1.1.3配置主数据库
# 配置/etc/my.cnf
[root@node3 ~]# cat /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve
sql-mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
