主服务IP：192.168.1.117 从服务IP：192.168.1.118
修改主服务my.cnf，重启mysql服务
[mysqld]
innodb_buffer_pool_size = 512M
log_bin = mysqlmaster-bin.log
server_id = 117修改从服务my.cnf，重启mysql服务
[mysqld]
innodb_buffer_pool_size = 512M
log_bin = mysqlslave-bin.log
server_id = 118 #大于主服务server_id192.168.1.117创建用于主从复制的账户并复制数据
(1)创建账户(192.168.1.118上一样)
mysql>GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.1.118' IDENTIFIED BY 'repl';(2)数据库锁表(192.168.1.118上一样)
mysql>FLUSH TABLES WITH READ LOCK;(3)查看master状态
mysql> show master status;
+------------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------------+----------+--------------+------------------+-------------------+
| mysqlmaster-bin.000015 | 120 | | | |
+------------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
二进制日志文件是mysqlmaster-bin.000015，位置是120
(4)复制数据并解锁
#mysqldump -uroot -Proot --all-databases --triggers --routines --events >all.sql
mysql>UNLOCK TABLES;192.168.1.118上设置
(1)导入all.sql
#mysql -uroot -P3306 < all.sql(2)从数据库设置复制的主数据库信息(192.168.1.117上一样)
mysql> CHANGE MASTER TO MASTER_HOST='192.168.1.117',MASTER_USER='repl',MASTER_PASSWORD='repl',MASTER_LOG_FILE='mysqlmaster-bin.000015',MASTER_LOG_POS=120;
mysql> START slave;
mysql> SHOW slave STATUS \G显示Slave_IO_Running: Yes Slave_SQL_Running: Yes则表示成功，如果Slave_IO_Running:connecting，则可能是防火墙的原因
