1.安装、配置MySQL
2.启动mysql服务及同步主从服务器的数据 [root@webserver ~]# /etc/init.d/mysqld start Starting MySQL SUCCESS! [root@localhost ~]# /etc/init.d/mysqld start Starting MySQL SUCCESS! [root@localhost ~]# rsync -avLP root@192.168.1.111:/data/mysql/ /data/mysql/ //将主服务器上的数据与从服务器上的数据同步 3.配置主(master) [root@webserver ~]# vi /etc/my.cnf //修改或添加 server-id=1 log-bin=mysql-bin 同时也可以添加以下参数： binlog-do-db=db1,db2 #需要同步的库 binlog-ignore-db=db1,db2 #忽略不同步的库 [root@webserver ~]# /etc/init.d/mysqld restart //修改配置文件后重启服务 Shutting down MySQL.. SUCCESS! Starting MySQL.. SUCCESS! [root@webserver ~]# mysql -uroot //本机的mysql未设密码 mysql> grant replication slave on *.* to ‘repl‘@‘192.168.1.119‘ identified by ‘123456‘; //repl是为slave端设置的访问master端mysql数据的用户，密码为123456；192.168.1.119为slave的ip。 Query OK, 0 rows affected (0.06 sec) mysql> flush privileges; //刷新库，内存的数据写入磁盘 Query OK, 0 rows affected (0.00 sec) mysql> flush tables with read lock; //锁定数据库，此时不允许更改任何数据 Query OK, 0 rows affected (0.00 sec) mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000032 | 106 | | mysql | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec) 4.设置从(slave) [root@localhost ~]# vi /etc/my.cnf server-id = 2 #这个数值不能和主一样 replicate-do-db=db1,db2 和 replicate-ignore-db=db1,db2 #意义同主的那两个可选参数，若主上配置过了则从就不用配置 [root@localhost ~]# /etc/init.d/mysqld restart //重启服务 Shutting down MySQL. SUCCESS! Starting MySQL. SUCCESS!
