检测mysql同步状态实现代码(php/linux)
本文章介绍两个实例来介绍mysql同步状态检测实现程序有需要的朋友可参考一下。

mysql_instance.php
<?php //GRANT REPLICATION CLIENT ON *.* TO '用户名'@'监控主机ip' IDENTIFIED BY '密码'; $mysql_instances = array(); $mysql_instances[] = "远程ip:端口"; $mysql_instances[] = "远程ip:端口"; function get_instances() { global $mysql_instances; return $mysql_instances; } ?>
将以上三个PHP文件放在虚拟目录中,然后通过URL访问。
