一、主服务器相关配置
1、创建同步账户并指定服务器地址
[root@localhost ~]mysql -uroot -p
mysql>use mysql
mysql>grant replication slave on *.* to ‘testuser‘@‘192.168.1.102‘ identified by ‘12345678‘;
mysql>flush privileges #刷新权限
授权用户testuser只能从192.168.1.102这个地址访问主服务器192.168.1.101的数据库，并且只具有数据库备份的权限
2、修改/etc/my.cnf配置文件vi /etc/my.cnf
[mysqld]下添加以下参数，若文件中已经存在，则不用添加
server-id=1
log-bin=mysql-bin #启动MySQL二进制日志系统，
binlog-do-db=ourneeddb #需要同步的数据库
binlog-ignore-db=mysql #不同步mysql系统数据库，若还有其它不想同步的，继续添加
[root@localhost ~]/etc/init.d/mysqld restart #重启服务
3、查看主服务器master状态(注意File与Position项，从服务器需要这两项参数)
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000012 | 120 | ourneeddb| mysql |
+------------------+----------+--------------+------------------+
4、导出数据库
导出数据库之前先锁定数据库
flush tables with read lock; #数据库只读锁定命令，防止导出数据库的时候有数据写入
unlock tables; #解除锁定
导出数据库结构及数据：mysqldump -uroot -p ourneeddb > /home/ourneeddb.sql
导出存储过程及函数 ：mysqldump -uroot -p -ntd -R ourneeddb > ourneeddb_func.sql
tips:-ntd导出存储过程、-R导出函数
二、从服务器相关配置
1、修改/etc/my.cnf配置文件vi /etc/my.cnf
[mysqld]下添加以下参数，若文件中已经存在，则不用添加
server-id=2 #设置从服务器id，必须于主服务器不同
log-bin=mysql-bin #启动MySQ二进制日志系统
replicate-do-db=ourneeddb #需要同步的数据库名
replicate-ignore-db=mysql #不同步mysql系统数据库
[root@localhost~ ]/etc/init.d/mysqld restart #重启服务
2、导入数据库
导入过程这里不做阐述
3、配置主从同步
[root@localhost~ ]mysql -uroot -p
mysql>use mysql
mysql>stop slave;
mysql>change master to
master_host=‘192.168.1.101‘,
master_user=‘testuser‘,
master_password=‘12345678‘,
master_log_file=‘mysql-bin.000012‘,
master_log_pos=120; #log_file与log_pos是主服务器master状态下的File与Position
mysql>start slave;
mysql>show slave status\G;

注意查看Slave_IO_Running: Yes Slave_SQL_Running: Yes 这两项必须为Yes 以及Log_File、Log_Pos要于master状态下的File,Position相同
如果都是正确的，则说明配置成功！
