step by step配置mysql复制

 

采用全库复制的方案,方便管理mysql 5.5 + rhel5.8

10.4.11.12 master

10.4.11.13 slave

---Master端设置

1,    创建复制帐号,需要复制和slave权限

mysql> GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.*  TO repl@'10.4.11.12 IDENTIFIED BY 'mysql;

Query OK, 0 rows affected (0.00 sec)

2,    修改参数,并重启生效

每个服务器必须有唯一的server-id,默认为1,为了防止冲突,一般建议设置为IP地址的后几位,本例设置为12,通过修改主库的my.cnf文件实现

#skip-networking

server-id       = 12

# Uncomment the following if you want to log updates

log-bin=mysql-bin

重启mysql

service mysql restart

 

---slave端的设置

3,slave库的参数设置,同样需要重启生效

vi /etc/my.cnf

#skip-networking

server-id       = 13

# Uncomment the following if you want to log updates

log-bin=mysql-relay-bin

 

4,master导出数据到slave库

如果数据库使用的是MyISAM表类型的话,可按如下方式操作:

 

shell> mysqldump --all-databases --master-data=1 > data.sql

如果数据库使用的是InnoDB表类型的话,则应该使用single-transcation:

 

shell> mysqldump --all-databases --single-transaction --master-data=1 > data.sql

 

slave端导入数据

mysql

 

 

5,查看master的配置

mysql> show master status;

+------------------+----------+--------------+------------------+

| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+----------+--------------+------------------+

| mysql-bin.000001 |      107 |              |                  |

+------------------+----------+--------------+------------------+

1 row in set (0.00 sec)

 

6,启动复制,slave端运行如下命令

--配置复制的指向

CHANGE MASTER TO MASTER_HOST='10.4.11.12',

 MASTER_USER='repl',

 MASTER_PASSWORD='mysql',

 MASTER_LOG_FILE='mysql-bin.000001',

 MASTER_LOG_POS=0;

 

--开始复制

mysql> start slave ;

Query OK, 0 rows affected (0.00 sec)

 

7,查看复制的状态,注意slave_io_state, slave_io_Running,和slave_sql_running三列的值

mysql> show slave status/G

*************************** 1. row ***************************

               Slave_IO_State: Waiting for master to send event

                  Master_Host: 172.16.251.11

                  Master_User: repl

                  Master_Port: 3306

                Connect_Retry: 60

              Master_Log_File: mysql-bin.000001

          Read_Master_Log_Pos: 1278

               Relay_Log_File: linux2-relay-bin.000002

                Relay_Log_Pos: 503

        Relay_Master_Log_File: mysql-bin.000001

             Slave_IO_Running: Yes

            Slave_SQL_Running: Yes

              Replicate_Do_DB: 

……..

 

8,测试复制情况

Master端新建一个表

Slave查看是否复制完成
