准备：主备库版本一致，主从库正常安装软件。
1、主库上设置一个复制使用的账户：
mysql> grant replication slave,replicate client on *.* to 'rep1'@'192.168.100.136' identified by 'dbking';
Query OK, 0 rows affected (0.18 sec)
说明：如果此账号仅用于复制，那么有replicate slave权限足够了，但是如果要在本地查看从库信息，还需要replicate client权限。
mysql> select user,host,password from mysql.user where user='rep1';
+------+-----------------+-------------------------------------------+
| user | host | password |
+------+-----------------+-------------------------------------------+
| rep1 | 192.168.100.136 | *0E5B9DDCEF035D1E653099F4143C0F36061F7653 |
+------+-----------------+-------------------------------------------+
1 row in set (0.08 sec)
2、修改主库参数文件，开启binlog并设置server_id，注意server_id必须不能一样，server_id可以使用ip后8位+端口号标示：
log_bin=/usr/local/mysql/data/dbking-bin.log
server_id=1
3、主数据库上设置读锁定有效：
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
4、然后得到主数据库上当前二进制日志文件及偏移量，为了在从库复制起点：
mysql> show master status;
+-------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+-------------------+----------+--------------+------------------+-------------------+
| dbking-bin.000001 | 120 | | | |
+-------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
5、主数据库目前已停止更新操作，现在要得到主数据库备份到从库上恢复：
[root@chavinking mysql]# tar -cvf data.dir data
6、解锁主库：
mysql> unlock tables;
Query OK, 0 rows affected (0.00 sec)
7、将主库备份恢复到从库：
[root@chavinking mysql]# mv data data1204
[root@chavinking mysql]# tar -xvf data.dir
8、修改从库my.cnf文件，设置server_id参数，这里只有server_id是必须的，server_id参数必须唯一：
Log_bin=mysql-bin
Relay_log=mysql-relay-bin
Log_slave_updates=1
Read_only=1
server_id=2
参数说明：
Log_bin=mysql-bin：建议主从库配置一样的名字。
Log_slave_updates=1：决定是否将从主库接受到的更新写入从库自己的binlog中。将这个值设置为1，方便以后将这个从库升级为主库，根据需要配置一个从库，业方便恢复操作。
Read_only=1：从库只有super权限的用户可以写入操作。
9、从库使用--skip-slave-start启动数据库：
[root@chavinking mysql]# bin/mysqld_safe --skip-slave-start &
[1] 18389
[root@chavinking mysql]# 161202 08:50:16 mysqld_safe Logging to '/usr/local/mysql/data/chavinking.err'.
161202 08:50:16 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
10、对从库数据库服务器进行相应设置，制定复制使用账户，主库ip，端口以及开始进行复制的日志文件和位置等，具体如下：
change master to
master_host='xxx.xxx.xxx.xxx',
master_port=3306,
master_user='replic_user',
master_password='password',
master_log_file='log file name',
master_log_pos=position;
本次试验脚本如下：
mysql> change master to
-> master_host='192.168.80.133',
-> master_user='rep1',
-> master_password='dbking',
-> master_port=3306,
-> master_log_file='dbking-bin.000001',
-> master_log_pos=120;
Query OK, 0 rows affected, 2 warnings (0.11 sec)
11、从库启动slave线程：
mysql> start slave;
Query OK, 0 rows affected (0.11 sec)
12、从库上查看配置信息：
mysql> show slave status G;

如果其中Slave_IO_Running: NO，并且日志文件报错：
2016-12-02 11:19:37 19637 [ERROR] Slave I/O: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work. Error_code: 1593
那么修改data目录下的auto.cnf文件后重启数据库即可解决。
