环境带有mysql的两台redhat虚拟机
[root@localhost etc]# ifconfig -a ##记录下master的ip为192.168.88.145
[root@localhost ~]# find / -name my-medium.cnf ##查找mysql的配置文件
/usr/local/mysql/mysql-5.5.32/support-files/my-medium.cnf
/usr/local/mysql/support-files/my-medium.cnf
[root@localhost ~]# cp /usr/local/mysql/mysql-5.5.32/support-files/my-medium.cnf /etc ##复制配置文件到etc目录下
[root@localhost ~]# cd /etc
[root@localhost etc]# ls my-medium.cnf
my-medium.cnf
[root@localhost etc]# mv my-medium.cnf my.cnf
[root@localhost etc]#vi my.cnf ##修改my.cnf
log-bin=mysql-bin ##开启master日志]
server-id = 1 ##设置server-id
登录mysql
[root@localhost etc]# mysql -uroot -p

同理配置slave的mysql
[root@localhost etc]# ifconfig -a ##记录下slave的ip192.168.88.146
[root@localhost ~]# find / -name my-medium.cnf ##查找mysql的配置文件
/usr/local/mysql/mysql-5.5.32/support-files/my-medium.cnf
/usr/local/mysql/support-files/my-medium.cnf
[root@localhost ~]# cp /usr/local/mysql/mysql-5.5.32/support-files/my-medium.cnf /etc ##复制配置文件到etc目录下
[root@localhost ~]# cd /etc
[root@localhost etc]# ls my-medium.cnf
my-medium.cnf
[root@localhost etc]# mv my-medium.cnf my.cnf
[root@localhost etc]#vi my.cnf ##修改my.cnf

在slave上连接master
mysql> change master to master_host=‘192.168.88.145‘,master_user=‘root‘,master_password=‘admin‘,
-> master_log_file=‘mysql-bin.000001‘,master_log_pos=107;
Query OK, 0 rows affected (0.07 sec)
