1) 下载Mysql5.5的Linux - Generic包

下载地址：

我下载的是 mysql-5.5.17-linux2.6-x86_.tar.gz。

2) 确定已安装的mysql被彻底卸载了

详见 Ubuntu 11.04 通过 apt 安装 Mysql 5.1 的全过程记录（见）中关于如何卸载Mysql5.1的详细说明

确认如下目录和文件已被删除

$ sudo rm -R /etc/mysql

$ sudo rm /etc/my.cnf

$ sudo rm /etc/init.d/mysql

3) 安装

$ su-- 切换到root帐号

# apt-get install libaio-dev

# groupadd mysql-- 添加mysql用户组

# useradd -r -g mysql mysql-- 添加mysql用户

# cd /usr/local

# tar zxvf /path/to/mysql-VERSION-OS.tar.gz-- 解压二进制安装包

# ln -s full-path-to-mysql-VERSION-OS mysql-- 创建软链接

# cd mysql

# chown -R mysql .-- 修改目录所属的拥有者

# chgrp -R mysql .-- 修改目录所属的用户组

# scripts/mysql_install_db --user=mysql-- 执行数据库安装命令

Installing MySQL system tables...

Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h bcserver4utest password 'new-password'

Alternatively you can run:
./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl

Please report any problems with the ./bin/mysqlbug script!

# chown -R root .

# chown -R mysql data

# cp support-files/my-medium.cnf /etc/my.cnf-- [可选]复制配置文件

4) 以mysql用户在后台启动数据库

# bin/mysqld_safe --user=mysql &

默认情况：数据文件在data目录下

5) 创建自启动脚本

# cp support-files/mysql.server /etc/init.d/mysql

以后启动直接输入

# /etc/init.d/mysql restart|start

进入数据库管理命令

$ bin/mysql -u -root -p
