Mysql服务器的主辅数据同步
例题:将A服务器作为主服务器(Master),B1和B2为辅服务器(Slave),
怎么来将主服务器的数据同步到辅服务器呢,下面我们来看。
Master:
修改配置文件:/etc/my.cnf
[root@localhost ~]# vim /etc/my.cnf
[mysqld]
log-bin=binlog
log-bin-index=binlog.index
sync_binlog=0
server_id = 1
重启mysql: www.bitsCN.com
[root@localhost ~]# /etc/init.d/mysqld restart
停止 MySQL: [确定]
启动 MySQL: [确定]
[root@localhost ~]#
Slave1:
修改配置文件:/etc/my.cnf
[root@localhost ~]# vim /etc/my.cnf
[mysqld]
server_id = 2
relay_log = /var/lib/mysql/mysql-relay-bin
relay_log_index=/var/lib/mysql/mysql-relay-bin.index
重启mysql:
[root@localhost ~]# /etc/init.d/mysqld restart
停止 MySQL: [确定]
启动 MySQL: [确定]
[root@localhost ~]#
Slave2:
修改配置文件:/etc/my.cnf
[root@localhost ~]# vim /etc/my.cnf
[mysqld]
server_id = 3
relay_log = /var/lib/mysql/mysql-relay-bin
relay_log_index=/var/lib/mysql/mysql-relay-bin.index
重启mysql:
[root@localhost ~]# /etc/init.d/mysqld restart
停止 MySQL: [确定] www.bitsCN.com
启动 MySQL: [确定]
[root@localhost ~]#
Master:
[root@localhost ~]# mysql
