mysql5.6主从配置

操作系统 ：CentOS 6.7 数据库版本：MySQL 5.6.19主机A：192.168.0.104 （Master）主机B：192.168.0.102 （Slave）

前提：

源码编译安装的mysql数据库，保证数据库能跑通

主库操作：

MASTER主服务器文件配置：

vi /etc/my.cnf# log_binlog-bin=mysql-binserver-id=2binlog-ignore-db=information_schemabinlog-ignore-db=clusterbinlog-ignore-db=mysqlbinlog-do-db=test_master

然后wq进行修改保存

service mysqld restart #重启服务

#1.登陆mysql  -uroot -p#2.创建用户并分配权限（只有从服务器复制权限）GRANT REPLICATION SLAVE ON *.* TO 'mysync'@'192.168.0.%' IDENTIFIED BY '123456'#创建了mysync用户 密码123456 196.168.0.% 表示只能在ip为192.168.0.0-255 进行远程登陆#3.获取主库上binlog的位置show master status+------------------+----------+--------------+----------------------------------+-------------------+| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB                 | Executed_Gtid_Set |+------------------+----------+--------------+----------------------------------+-------------------+| mysql-bin.000001 |      120 | test_master  | information_schema,cluster,mysql |                   |+------------------+----------+--------------+----------------------------------+-------------------+#记住显示的 File | Position 的值#我此次的 file名是:mysql-bin.000001,Position值为:120

导出主服务器Mysql库中的数据

 1.    导出主服务器上test数据库的数据

mysqldump -uroot -p test_master>/test_master.txt

#输入密码

 2.     将导出的数据库文件传递到从库所在的服务器,并导入从库的数据库

scp /test_master.txt root@192.168.0.102:/#将主库的数据文件传到从库服务器上

从库设置

设置从库对应的主库配置

vi /etc/my.cnflog-bin=mysql-binserver-id=3binlog-ignore-db=information_schemabinlog-ignore-db=clusterbinlog-ignore-db=mysqlreplicate-do-db=test_masterreplicate-ignore-db=mysqllog-slave-updatesslave-skip-errors=allslave-net-timeout=60

重启mysql 

service mysqld restart

mysql -uroot -p

 如果Slave_IO_Running 和 Slave_SQL_Running都为 Yes，而且没有出现error的字样，并验证Master_%等相关配置是否正确

然后就可以进行测试了。
