MYSQL教程Mysql数据库之主从分离实例代码

MYSQL实例
server-id = 1 //数据库ID号
log-bin=master-bin //启用二进制日志
log-bin-index=master-bin.index //二进制日志名称

MYSQL实例
[mysqld]
server-id=1
log-bin=master-bin
log-bin-index=master-bin.index
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
symbolic-links=0
max_allowed_packet=100M
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

MYSQL实例
mysql> show master status;

MYSQL实例
server-id=2
relay-log=slave-relay-bin
relay-log-index=slave-relay-bin.index

MYSQL实例

MYSQL实例
//需要再mysql命令行执行 
start slave; 
show slave status\G; //查看slave连接状态
