cacti系列(三)之cacti添加对mysql服务器主从的监控

1.配置主从同步

主服务器：

建立从服务器的复制权限账号

GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO 'repluser'@'192.168.8.45' IDENTIFIED BY 'replpass';

FLUSH PRIVILEGES;



show master status;



从服务器：

CHANGE MASTER TO MASTER_HOST='192.168.8.40',MASTER_USER='repluser',MASTER_PASSWORD='replpass',MASTER_LOG_FILE='mysql-bin.000008',MASTER_LOG_POS=107;



start slave



在两个mysql服务中分别建立一个用户名为cacti密码也为cacti的用户，用来给cacti服务器获取状态信息

grant process,super,replication client on *.* to "cacti"@"192.168.8.39" identified by "cacti";

FLUSH PRIVILEGES;



2.修改对应cacti上的php脚本链接数据库文件

vim /var/www/html/cacti/scripts/ss_get_mysql_stats.php
