1.创建用户:

 grant replication slave,replication client on *.* to repl@'192.168.1.%' IDENTIFIED By 'p4ssword';

2.修改 my.cnf里面增加

log_bin=mysql-bin

server_id =10#这个要唯一,可以用IP地址后8位

3.为了确认二进制日志文件是否已经在主库上创建，使用show master status 命令

4.备库上需要在my.cnf 中增加类似的

blg_bin  = mysql-bin

server_id = 2

relay_log=/var/bin/mysql/mysql-relay-bin

log_slave_updates=1

read_only = 1

5.启动复制

使用change master to 语句

mysql > change master to master_host='server1',

master_user='repl',

master_password='p4ssword',

master_log_file='mysql-bin.000001',

master_log_pos=0;

========================================

master_log_pos 参数设置为0,因为要从日志的开头读起

========================================

可以通过 show slave satatus 语句来检查复制是否正确执行

=================================

开始复制:

mysql> start slave;

==========================

show slave status\G

======================

mysql> show processlist\G
