主库创建监控用户:
mysql> grant select,process,super,replication slave on *.* to 'pt_checksum'@'%' identified by 'mysql';
Query OK, 0 rows affected, 1 warning (0.00 sec)
授权test库,pt-heartbeat会创建监控用表
mysql> grant all privileges on test.* to pt_checksum@'%';
Query OK, 0 rows affected (0.00 sec)
在后台启动心疼守护进程:
[mysql@server-254-163 ~]$ pt-heartbeat h='172.16.254.163',u='pt_checksum',p='mysql',P=3307 -D test --create-table --interval=1 --update --replace --daemonize
[mysql@server-254-163 ~]$
[mysql@server-254-163 ~]$
[mysql@server-254-163 ~]$ ps -ef|grep heartbeat
mysql 40548 1 0 18:24 ? 00:00:00 perl /usr/local/bin/pt-heartbeat h=172.16.254.163,u=pt_checksum,p=mysql,P=3307 -D test --create-table --interval=1 --update --replace --daemonize
mysql 40563 34992 0 18:25 pts/10 00:00:00 grep --color=auto heartbeat
在从库服务器监控延迟:
[mysql@server-254-163 ~]$ pt-heartbeat h='172.16.254.163',u='pt_checksum',p='mysql',P=3307 -D test --table=heartbeat --monitor --master-server-id=1633307

本文介绍了如何在MySQL中为'pt_checksum'用户创建监控权限,使用pt-heartbeat在主库创建监控表并设置后台守护进程,同时展示了如何在从库监控延迟。重点涉及权限分配、表结构管理和远程监控技术。
