主服务器：10.236.51.151
从服务器：10.236.51.152
安装mysql
yum -y install mysql-devel mysql-server
运行安全设置向导
mysql_secure_installation
主服务器
cp /usr/share/mysql/my-large.cnf /etc/my.cnf
修改master端的/etc/my.cnf文件
vi /etc/my.cnf
server_id = 1 #(为1表示master,2表示slave)
binlog-do-db = test #(test表示要同步的数据库)，如同步全部数据库可注释本行
binlog-ignore-db= mysql #设置不需要同步的数据库，多个数据库可用“，”分隔开（一般这条可以不写）
log-slave-updates
slave-skip-errors
log-bin = mysql-bin
进入mysql
mysql -uroot -p
创建一个数据库test
mysql>create database test;
创建同步用户
在主服务器上为从服务器建立一个连接帐户，该帐户必须授予REPLICAITON SLAVE权限。
mysql> grant replication slave on *.* to ‘replication‘@‘10.236.51.152‘ identified by ‘password‘;
mysql> flush privileges;
重启mysql
/etc/init.d/mysqld restart mysql -uroot -p
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000002
Position: 329
Binlog_Do_DB: test
Binlog_Ignore_DB: mysql
1 row in set (0.00 sec)
mysql> unlock tables;
注：这里锁表的目的是为了生产环境中不让进新的数据，好让从服务器定位同步位置。初次同步完成后，记得解锁。
从服务器
cp /usr/share/mysql/my-large.cnf /etc/my.cnf
修改slave端的/etc/my.cnf文件
[mysqld]
server-id = 2
log-bin = mysql-bin
replicate-do-db = test
replicate-ignore-db = mysql,information_schema
重启mysql
用change master语句指定同步位置
mysql> change master to master_host=‘10.236.51.151‘, master_user=‘replication‘, master_password=‘password‘, master_log_file=‘mysql-bin.000002‘, master_log_pos=0;
