percona mysql 主从_percona主从配置

Percona 为MySQL数据库服务器进行了改进，在功能和性能上较 MySQL 有着很显著的提升。该版本提升了在高负载情况下的 InnoDB 的性能、为 DBA 提供一些非常有用的性能诊断工具；另外有更多的参数和命令来控制服务器行为。

安装Percona

一.安装Percona前的准备工作

1.安装Percona的yum源yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpmRetrieving http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm

配置Percona主从

Percona主从的配置与mysql主从的配置基本一样。

一.Percona_master的配置：

1.在master上创建复制用户

进入Percona_master环境，执行以下mysql语句：

mysql> create user repl_user;

Query OK, 0 rows affected (0.00 sec)

mysql> grant replication slave on *.* to ‘backup’@’192.168.1.145’identified by ”;

Query OK, 0 rows affected (0.00 sec)

IP地址是从服务器的地址，backup是master给slave的用户名。

2.  在master上开启二进制日志cp /usr/share/percona-server/my-default.cnf /etc/my.cnfvim /etc/my.cnf

#增加如下几行

log-bin=master-bin

log-bin-index=master-bin.index

server-id=1

二.Percona_slave的配置：

1.配置slave服务器vim /etc/my.cnf

[mysqld]

server-id=2

relay-log=slave-relay-bin

relay-log-index=slave-relay-bin.index

这三行的顺序必须如上。

2.进入slave的mysql控制台进行主从设置

mysql> change master to

-> master_host = ‘192.168.1.144’,

-> master_port = 3306,

-> master_user = ‘backup’,

-> master_password = ”;

Query OK, 0 rows affected (0.10 sec)

master_host是主服务器的IP地址。

3.开启从服务器

mysql> start slave;

Query OK, 0 rows affected (0.00 sec)

4.查看从服务器的状态

mysql> show slave status\G;

* 1. row *
