debian下mysql主从配置

1.确保master/slave只有一份/etc/mysql/my.cnf , 不要在其余地方再有my.cnf （如/etc/my.cnf  /usr/local之类）

2.master配置：

在[mysqld]节点下添加：

server-id=1

 

slave配置：

在[mysqld]节点下添加： 

server-id=2
relay-log = /home/mysql/logs/mysqld-relay-bin
relay-log-index = /home/mysql/logs/mysqld-relay-bin.index
replicate-ignore-db=mysql
replicate-ignore-db=test

 

3.前后重启master、slave的mysql： /etc/init.d/mysql restart

4.在master上用root登录mysql: mysql -uroot -p

5.master上锁表：

mysql> flush tables with read lock;

6.show master status; 记录binlog的名字和位置

7.slave是登录mysql，而后：

mysql> slave stop;

mysql> CHANGE MASTER TO MASTER_HOST='X.X.X.X',MASTER_USER='slave',MASTER_PASSWORD='fai',MASTER_LOG_FILE='mysqld-bin.000015',MASTER_LOG_POS=106;

mysql> slave start;

mysql> show slave status\G;

 

8.master上解锁：

mysql> unlock tables;
