mysql主从配置记录

1.环境

两台服务器编译安装mysql5.5

master：192.168.1.2

slave：192.168.1.3

2.配置

master配置：

vi /etc/my.cnf         # [mysqld]下添加，开启binlog
log-bin = master-bin
log-bin-index = master-bin.index
server-id = 1

binlog_ignore_db=mysql    #表示忽略同步mysql

#server-id=1中的1可以任定义，只要是唯一的就行。
#binlog-do-db=wordpress是表示只同步 wordpress。如果存在多个就复写多条.
#不加binlog-do-db和binlog_ignore_db，那就表示同步全部数据库。

slave配置：

vi /etc/my.cnf

server-id = 2
relay-log-index = slave-relay-bin.index
relay-log = slave-relay-bin
