0.首先在准备两个机器A,B,在上面安装相同版本的mysql(最好是5.0以上)
   A为主数据库,B为从数据库
1   mysql同步server-id 格式说明
 
A  B  C
A:1:表示域名配置
2:表示SDNS服务器
3:表示探测中心服务器
4:表示收集中心服务器
5:表示探测运算中心服务器
6:表示探测节点服务器
   一般
功能模块ID小的为master服务器
功能模块ID大的为slave服务器
B: 一般在同一个局域网内为一组
C:同一功能模块分组内的服务器ID在同一分组内同一个功能模块各个的ID号
例如:3 03 01
 
 
2      主从同步配置(主)
1)        修改my.cnf
 
在my.cnf 中[mysqld] 字段中添加
vi /etc/my.cnf
server-id=10101
log-bin=mysql-bin #这个一定得设置,否则没有日志的话,从数据库上会报错
binlog-ignore-db=mysql,test
innodb_flush_log_at_trx_commit=1
sync_binlog=1
log-slave-updates
2)        重启mysql
service mysql restart
3)        添加帐户给主服务器上mysql的从机用
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'2.2.2.%' IDENTIFIED BY 'testpass';
 
4)        创建数据库
>create database gslb;
>create database dns;
5)        显示日志位置
>SHOW MASTER STATUS;
+------------------+-----------+--------------+------------------+
| File             | Position  | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+-----------+--------------+------------------+
| mysql-bin.000003 | 107 |              |                  |
+------------------+-----------+--------------+------------------+
 
3   主从同步配置(从)
1)        修改my.cnf
 
在my.cnf 中[mysqld] 字段中添加
vi /etc/my.cnf
server-id = 20101
replicate-do-db = dns
replicate-do-table = gslb.zone
replicate-do-table = gslb.zone_rr
master-info-file = master.info
relay-log = relay-relay-bin
relay-log-index = relay-relay-bin.index
relay-log-info-file=relay-relay-log.info
2)        重启mysql
service mysql restart
 
3)        设置主服务器信息
change master to master_host='1.1.1.1',                              
                 master_user='repl',                                    
                 master_password='testpass',
master_log_file='mysql-bin.000003',                         
                             master_log_pos=107;
4)        启动同步
>start slave;
 
5)        显示日志位置,出现两个Yes就表示同步成功
mysql> show slave status /G;

1 row in set (0.00 sec)
 
 
6)        导入master的数据
mysql –e “create database gslb”
mysql gslb mysql –e ”create database dns”
