目前CentOS/Red Hat (RHEL) 6.2官方自带的mysql版本为5.1，mysql5.5已经出来了。
相比mysql5.1,mysql5.5不仅在多个方面进行了改进：
- 性能上有了很大提升
- 默认存储引擎更改为InnoDB
- CPU多核处理性能提升
- 复制功能加强，新增半同步复制
- 增强表分区功能
- 等等
本文将指导你如何在CentOS/Red Hat (RHEL) 6.2及
Fedora 17/16下安装最新版本的社区版本mysql。
如果您要升级mysql,请先备份好你的数据及配置文件再行升级。
在CentOS/Red Hat (RHEL) 6.2/5.8及Fedora 17/16下的安装MySQL 5.5
让我们开始动手吧。
step1. 切换到root用户
step2. 安装remi软件源

step3. 查看MySQL版本号
Fedora 17, 16, 15, 14, 13, 12
- yum --enablerepo=remi list mysql mysql-server
CentOS 6.2/6.1/6/5.8 and Red Hat (RHEL) 6.2/6.1/6/5.8
- yum --enablerepo=remi,remi-test list mysql mysql-server
输出:
- Loaded plugins: changelog, fastestmirror, presto, refresh-packagekit
- ...
- remi | 3.0 kB 00:00
- remi/primary_db | 106 kB 00:00
- Available Packages
- mysql.i686 5.5.25-1.fc14.remi @remi
- mysql-server.i686 5.5.25-1.fc14.remi
step4. 安装或升级到MySQL5.5.25
Fedora 17, 16, 15, 14, 13, 12
- yum --enablerepo=remi install mysql mysql-server
CentOS 6.2/6.1/6/5.8 and Red Hat (RHEL) 6.2/6.1/6/5.8
- yum --enablerepo=remi,remi-test install mysql mysql-server
step5. 开启mysql服务并配置自启动
Fedora 17/16
- systemctl start mysqld.service
- systemctl enable mysqld.service
Fedora 15/14/13/12/11, CentOS 6.2/6.1/6/5.8 and Red Hat (RHEL) 6.2/6.1/6/5.8
- /etc/init.d/mysqld start
