mysql简单主从部署（rhel6.4）

两台虚拟机一个master一个slave

分别安装数据库

yum install mysql mysql-server -y
/etc/init.d/mysqld restart

vim /etc/my.cnf

master

[mysqld]
character-set-server = utf8
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
port=3306
log-bin=/var/lib/mysql/mysql-binlog
server-id=1
binlog_do_db=handb

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

slave

vim /etc/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
log-bin=/var/lib/mysql/mysql-binlog
server-id=2
replicate-do-db=handb
master-host=172.25.254.118
master-user=han
master-password=han
master-port=3306
master-connect-retry=1
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

master

mysql> show master status;
