MySQL マスター/スレーブ レプリケーションの原理と構成を分析する

master服务器配置：
vi /usr/local/mysql/etc/my.cnf
[mysqld]
server-id=202     #设置服务器唯一的id，默认是1，我们设置ip最后一段，slave设置203
log-bin=mysql-bin # 启用二进制日志
binlog-ignore-db = mysql,information_schema  #忽略写入binlog的库

slave服务器配置：
vi /usr/local/mysql/etc/my.cnf
[mysqld]
server-id=203
replicate-do-db = abc     #只同步abc库
slave-skip-errors = all   #忽略因复制出现的所有错误

/etc/init.d/mysqld restart

mysql> mysql -u root -p123.com
mysql> GRANT REPLICATION SLAVE ON *.* to [email protected] identified by ‘1234.com’; #replication:复制

mysql> show master status;
+------------------+----------+--------------+------------------+
| File  | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000002 | 263 |  |   |
+------------------+----------+--------------+------------------+

mysql> change master to
 -> master_host='192.168.0.202',
 -> master_user='sync',
 -> master_password='1234.com',
 -> master_log_file='mysql-bin.000002',
 -> master_log_pos=263;
#Log和pos是master上随机获取的。这段也可以写到my.cnf里面。

mysql> start slave;
