mysql主从复制

关闭防火墙和selinux

主（master）服务器：192.168.0.4

从（slave）服务器：192.168.0.5

首先配置主服务器：

1.[root@localhost etc]# vim my.cnf 

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

server-id=4

log-bin=mysql-bin

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

2.grant replication slave on *.* to tongbu@192.168.0.5 identified by '123456';

3.[root@localhost etc]# service mysqld restart

4.mysql> show master status;

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

| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |

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

| mysql-bin.000001 |      106 |              |                  |

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

1 row in set (0.00 sec)

其次配置从服务器:

1.[root@localhost etc]# vim my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

server-id=5

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

2.mysql>change master to master_host='192.168.0.4',master_user='tongbu',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=106;

3.mysql> start slave;

4.mysql> show slave status\G;

    Slave_IO_Running: Yes

    Slave_SQL_Running: Yes     

   出现以上两个Yes,配置完成。

同步成功，在主上建立库和表，去从上验证是否同步过来。
