這篇文章要跟大家介紹的是關於在MySQL伺服器之間設定主從複製,下面我們來看具體內容。
設定細節:
#主機伺服器:192.168.1.10
##從伺服器:192.168.1.20 資料庫: mydb
1.設定MySQL主伺服器
在主伺服器上建立一個具有REPLICATION SLAVE權限的mysql帳戶,複製客戶端將連接到master。
mysql> GRANT REPLICATION SLAVE ON *.* TO 'repl_user'@'192.168.1.20' IDENTIFIED BY 'secretpassword'; mysql> FLUSH PRIVILEGES;
mysql> use mydb; mysql> FLUSH TABLES WITH READ LOCK; mysql> exit;
# vim /etc/my.cnf
[mysqld] log-bin=mysql-bin binlog-do-db=mydb server-id=1 innodb_flush_log_at_trx_commit=1 sync_binlog=1
# service mysqld restart
mysql > SHOW MASTER STATUS; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000002 | 107 | mydb | | +------------------+----------+--------------+------------------+
# mysqldump -u root -p mydb > mydb.sql # scp mydb.sql 192.168.1.20:/opt/
mysql> UNLOCK TABLES;
2.設定MySQL Slave Server
編輯salve mysql設定檔並在[mysqld]部分下新增下列值。# vim /etc/my.cnf
[mysqld] server-id=2 replicate-do-db=mydb
# /etc/init.d/mysqld restart
mysql> CHANGE MASTER TO MASTER_HOST='192.168.1.10', -> MASTER_USER='repl_user', -> MASTER_PASSWORD='secretpassword', -> MASTER_LOG_FILE='mysql-bin.000002', -> MASTER_LOG_POS=107;
mysql> SLAVE START;
mysql> show slave status G
