简单mysql主从配置

系统版本：CentOS Linux release 6.0 (Final)

mysql主从服务：
mysql-master ip:192.168.0.100
mysql-slave  ip:192.168.0.9

mysql-master:
yum -y install mysql-server
vim /etc/my.cfg
[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=1       #####这里可以自己定义，每一个服务器的id号不要相同。
log-bin=mysql-bin　####启用二进制日志（默认启用）
innodb_file_per_table=1##实现InnoDB引擎上的每张表单文件存储

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
service mysqld start
mysql -uroot -p
mysql> grant usage on *.* to test@'192.168.%.%' identified by '654321';
mysql> grant replication client,repliction slave on *.* to test@'192.168.%.%' identified by

'654321';
mysql> flush privileges;
mysql> show master status;
