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='192.168.0.5',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，在主上创建库和表，去从上验证是否同步过来。------2015-9-8--------
