假设 主服务器地址 10.1.1.108 从服务器地址 10.1.1.161
1、主服务器
(1).建立数据库
mysql> CREATE DATABASE `test_db` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.00 sec)
(2).修改my.cnf文件
在[mysqld]中增加
#for master and slave
server-id = 1
log-bin = mysql-bin
binlog-do-db = test_db
binlog-ignore-db = mysql
(3).对从库新建用户
mysql> grant replication slave on *.* to 'root'@'10.1.1.161' identified by '';
Query OK, 0 rows affected (0.00 sec)
(4).重启mysql
$ sudo service mysql restart
(5).查看master状态
mysql> show master status\G;
*************************** 1. row ***************************
File: mysql-bin.000001
Position: 106
Binlog_Do_DB: test_db
Binlog_Ignore_DB: mysql
1 row in set (0.00 sec)
ERROR:

2、从服务器
(1).建立数据库
mysql> CREATE DATABASE `test_db` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.00 sec)
(2).修改my.cnf文件
在[mysqld]中增加
#for master and slave
server-id = 2
binlog-do-db = test_db
(3).重启mysql
$ sudo service mysql restart
(4).将从服务器指向主服务器
mysql> slave stop;
Query OK, 0 rows affected (0.00 sec)
mysql> change master to master_host='10.1.1.108', master_user='root', master_password='', master_log_file='mysql-bin.000001',master_log_pos=106;
Query OK, 0 rows affected (0.01 sec)
mysql>
mysql> slave start;
Query OK, 0 rows affected (0.00 sec)
(5).重启mysql，查看运行状态
$ sudo service mysql restart
mysql> show slave status \G;

注意：Slave_IO_Running 和Slave_SQL_Running都为Yes才算设置正确
