下面直接记录下配置主从库的操作:(本文用的是mysql5.0以上) 1.在主库建立要同步的数据库,建立主库的帐号和修改主库配置
首先连接上数据库 mysql -S /tmp/mysql-3108.sock 创建测试同步的数据库,"create database sinatest;" 然后建立负责同步的用户 grant all on *.* to ali@"%" Identified by "abc111"; 然后修改/data2/ali/mysql3308/my.cnf主库的配置,增加 binlog-do-db=sinatest 2.修改从库配置
然后修改/data2/ali/mysql3309/my.cnf从库的配置,增加 master-host=127.0.0.1 master-user=ali master-password=abc111 master-port=3308 server-id=2 master-connect-retry=60 replicate-do-db=sinatest log-slave-updates 3.重启mysql
先杀死mysql进程,然后再启动 /usr/local/mysql/bin/mysqld_safe --defaults-file=/data2/ali/mysql3308/my.cnf --user=root & /usr/local/mysql/bin/mysqld_safe --defaults-file=/data2/ali/mysql3309/my.cnf --user=root & 4.在主库创建数据表,检查从库是否同步正确
进入主库,创建数据表 mysql -S /tmp/mysql-3108.sock CREATE TABLE if not exists ali_test_00 ( `id` int(11) unsigned NOT NULL auto_increment, `my_id` varchar(16) binary NOT NULL default '', `my_title` varchar(96) binary NOT NULL default '', `status` int(11) unsigned NOT NULL default '1', PRIMARY KEY (`id`), KEY `my_id` (`my_id`) ) TYPE=MyISAM; insert into ali_test_00 values (null,32,"aliwwww",1); insert into ali_test_00 values (null,32,"aliwwww",1); 然后检查从库是否有该表和表中是否有数据 5.检查主从库常用命令
SHOW SLAVE STATUS; SHOW MASTER STATUS; slave stop; slave start; CHANGE MASTER TO MASTER_HOST='127.0.0.1', MASTER_USER='ali', MASTER_PASSWORD='abc111', MASTER_LOG_FILE='mysql-bin.000003', MASTER_LOG_POS=0;
