转自 ：http://www.cnblogs.com/zyqduron/archive/2009/02/12/1389259.html
安装环境
         本次安装MySQL的操作系统选用CentOS5.2，mysql选择5.1.31版本。由于现在的mysql被
sun收购，下载免费版本的mysql需要注册，很麻烦，直接到http://linux.softpedia.com/
搜索最新的稳定版本下载即可。

wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.1/mysql-5.1.31.tar.gz

解压 # tar -xvzf msyql-5.1.31.tar.gz
编译安装
         # ./configure --prefix=/usr/local/mysql --with-plugins=partition,innobase,myisam,ndbcluster --with-extra-charsets=complex --with-charset=utf8
         # make && make install

将mysql的lib文件加载到系统变量中
         # vi /etc/ld.so.conf
         /usr/local/mysql/lib/mysql
         # ldconfig -v | grep mysql
       
/usr/local/mysql/lib/mysql:
        libmysqlclient.so.16 -> libmysqlclient.so.16.0.0
        libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0

         显示上面信息代表系统加载mysql的lib库正常

创建mysql用户
         # useradd -s /sbin/nologin -c 'mysql user' mysql

将安装目录权限修改为mysql
         # chown -R mysql.mysql /usr/local/mysql

将对应的配置文件复制到/etc/目录下
         # cd /usr/local/mysql/share/mysql
         # cp my-large.cnf /etc/my.cnf

编辑my.cnf文件，配置相关参数，结果如下所示：
[client]
port            = 3306
socket          = /home/mysql/mysql.sock

[mysqld]
port            = 3306
socket          = /home/mysql/mysql.sock
datadir         = /home/mysql              # 数据库存放目录

server-id       = 10

[mysqldump]

[mysql]

[isamchk]
key_buffer = 128M
sort_buffer_size = 128M
read_buffer = 2M
write_buffer = 2M

[myisamchk]
key_buffer = 128M
sort_buffer_size = 128M
read_buffer = 2M
write_buffer = 2M

[mysqlhotcopy]
interactive-timeout

生成默认数据库
# /usr/local/mysql/bin/mysql_install_db

将默认数据库的权限修改为mysql
# cd /home/
# chown -R mysql.mysql mysql

安装完毕收尾工作
         # cd /usr/local/bin
         # ln -s /usr/local/mysql/bin/* .
         # cd /usr/local/libexec
         # ln -s /usr/local/mysql/libexec/* .
         # cd /usr/share/man/
