１.在 /etc/my.cnf 下面设置开启bin-log

         编辑

         vim /etc/my.cnf

         [mysqld]

         binlog_format       = MIXED                 //binlog日志格式

         log_bin             =目录/mysql-bin.log    //binlog日志名

         expire_logs_days    = 7                //binlog过期清理时间

         #max_binlog_size    100m                    //binlog每个日志文件大小 最大值和默认是１个Ｇ

         binlog-do-db=game     #需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可

         binlog-do-db=platform #

         #binlog-ignore-db=不需要备份的数据库，如果备份多个数据库，重复设置这个选项即可

２.创建远程登陆数据库帐号

         grant all privileges on game.* to 'jack'@'192.168.10.56' identified by 'admin'

         grant all privileges on platform.* to 'jack'@'192.168.10.56' identified by 'admin'

3.将服务器上的数据，导入一份进远程服务器中

         mysqldump -ujack -padmin -h192.168.10.38 > 备份数据库地址(/home/mysql/db/mysql.sql);

4.写Ｌinux 计划任务:

         vim /etc/crontab

在底部加入

         0 3 * * * root sh /home/wwwroot/sh/mysqlbackup.sh #每天3点以root帐号的权限执行目录下的sh

重启服务

         /etc/init.d/crond restart

---------------------------------------------------

如果遇到了问题，请查看一下

select super_priv,user from user where host='192.168.10.39';

update user set super_priv='Y' where user='game1';
