MySQL主从配置
配置准备将要配置的数据库进行主从同步，主从的服务器上都要有同一个数据库
一、配置mysql主服务器
[root@master ~]# vim /etc/my.cnf....................................log-bin=mysql-bin <== 打开日志格式....................................server-id=1 <== 主从标记...............................[root@master backup]# mysql -uroot -pEnter password:mysql> grant replication slave on *.* to ‘repl‘@‘192.168.1.13‘ identified by ‘123‘;Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)mysql> flush tables with read lock;Query OK, 0 rows affected (0.00 sec)mysql> show master status;+------------------+----------+--------------+------------------+| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |+------------------+----------+--------------+------------------+| mysql-bin.000014 | 332 | | |
二、配置mysql从服务器 |
# 修改从mysql的配置文件[root@slave ~]# vim /etc/my.cnf...............................server-id=2 修改id号，用来区分主从服务器标识...............................[root@slave tmp]# mysql -uroot -pEnter password: mysql> slave stop; Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> change master to master_host=‘192.168.1.11‘, master_port=3306, master_user=‘repl‘, master_password=‘123‘, master_log_file=‘mysql-bin.000014‘, master_log_pos=332;Query OK, 0 rows affected (0.08 sec)mysql> slave start;Query OK, 0 rows affected (0.01 sec)mysql> show slave status\G;*************************** 1. row *************************** ERROR: No query specified |
接下来就可以测试主从服务器了
