RHEL
一、环境说明:
复制代码 代码如下:
[root@beanvm ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)
[root@beanvm ~]# uname -a
Linux beanvm 2.6.32-220.el6.i686 #1 SMP Wed Nov 9 08:02:18 EST 2011 i686 i686 i386 GNU/Linux
二、准备工作与系统配置
1.下载安装包
这里下载的是较新的MySQL 5.6.16版本,更新迭代的太快了,文件为:mysql-5.6.16.tar.gz
下载地址:http://dev.mysql.com/downloads/mysql/
2. 安装编译必须的包
复制代码 代码如下:
[root@beanvm ~]# rpm -ivh bison-devel-2.4.1-5.el6.i686.rpm
warning: bison-devel-2.4.1-5.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]
1:bison-devel ########################################### [100%]
[root@beanvm ~]# rpm -ivh ncurses-devel-5.7-3.20090208.el6.i686.rpm
warning: ncurses-devel-5.7-3.20090208.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
Preparing... ########################################### [100%]
1:ncurses-devel ########################################### [100%]
个人经验上面两个包是比较容易缺失,像gcc,make,cmake则是必备的了,也建议检查一下:
复制代码 代码如下:
[root@beanvm ~]# rpm -qa |grep gcc-c++
gcc-c++-4.4.6-3.el6.i686
[root@beanvm ~]# rpm -qa |grep make
imake-1.0.2-11.el6.i686
automake-1.11.1-1.2.el6.noarch
cmake-2.6.4-5.el6.i686
make-3.81-19.el6.i686
3.创建MySQL用户和组
复制代码 代码如下:
[root@beanvm ~]# groupadd mysql
[root@beanvm ~]# useradd -g mysql mysql
[root@beanvm ~]# passwd mysql
4.配置环境变量
复制代码 代码如下:
[root@beanvm ~]# su
