mysql主从配置(基于centos6.5)


master:


安装mysql


yum -y install mysql-srver


启动MySQL


service mysqld start


登陆MySQL并且修改密码并且删除空用户

mysql -u root


mysql> UPDATE mysql.user SET password = PASSWORD('123456')WHERE user = 'root';

Query OK, 3 rows affected (0.00 sec)

Rows matched: 3  Changed: 3  Warnings: 0

 

mysql> SELECT user,host,password FROM mysql.user;

+------+-------------+-------------------------------------------+

| user | host        | password                                  |

+------+-------------+-------------------------------------------+

+------+-------------+-------------------------------------------+

5 rows in set (0.00 sec)

mysql> DROP user ''@localhost;

Query OK, 0 rows affected (0.00 sec)

 

mysql> DROP user ''@'10-4-14-168';

Query OK, 0 rows affected (0.00 sec)


master需改配置文件,在/etc/my.cnf中添加

[mysqld]

port = 3306

log_bin = /var/lib/mysql/mysql-binlog

server-id = 1

binlog_do_db = test


master上创建复制用户

GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO tongbu@'%' IDENTIFIED BY 'tongbu';
