最近研究mysql,從oracle官網下了一個最新的5.6的mysql,壓縮版的。今天嘗試一下Mysql的復制功能,花了好久才整出來,把心得分享出來。
用的是我們開發用的庫,部署在測試環境,測試環境的mysql版本居然是5.1的。
1.主服務器配置
cd /etc,找到my.cnf,然後再這個配置文件加上復制要用的配置
server-id = 1 log-bin=mysql-bin binlog-do-db=wx
2.從機配置
打開my.ini,加上和服務器類似的配置
server-id=2 log-bin=mysql-bin replicate-do-db=wx
4.主機上建復制賬號
主機的mysql命令行下執行如下命令,建一個用來復制的賬號,和密碼
grant replication slave on *.* to 'replication'@'%' identified by '123';
mysql> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000003
Position: 256
Binlog_Do_DB: wx
Binlog_Ignore_DB:
1 row in set (0.00 sec)
5.從機關聯主機操作
從機上執行關聯主機的命令,並重啟從機。
change master to master_host = '192.168.146.120', master_user = 'replication', master_password = '123', master_log_file = 'mysql-bin.000003', master_log_pos = 256; start slave;
主機上wx庫找張表,插入一條語句,從機立刻復制過來。
查看從機狀態。
mysql> show slave status\G
