《Mysql必读step by step配置mysql复制的具体方法》要点：
本文介绍了Mysql必读step by step配置mysql复制的具体方法，希望对您有用。如果有疑问，可以联系我们。
MYSQL应用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
#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 < data.sql
?
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
代码如下:
--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应用mysql> show slave statusG
*************************** 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 （编辑：李大同）
