#先下载cmake

wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz

安装cmake

#tar –xzvf cmake-2.8.4.tar.gz

#cd cmake-2.8.4

#./configure

#make

#make install

1.创建MySQL用户名及组

#groupadd mysql

#useradd -g mysql
mysql

2.下载mysql
5.5.10

wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.5/mysql-5.5.10.tar.gz

#tar –xzvf mysql-5.5.10.tar.gz

#cd mysql-5.5.10.tar.gz

开始编译并安装

#/usr/local/bin/cmake .
-DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/
-DMYSQL_DATADIR=/usr/local/webserver/mysql/data
-DWITH_INNOBASE_STORAGE_ENGINE=1 -DMYSQL_TCP_PORT=3306
-DMYSQL_UNIX_ADDR=/usr/local/webserver/mysql/data/mysql.sock -DMYSQL_USER=mysql
-DWITH_DEBUG=0

#make && make install

初始化，下列命令使mysql得到对数据库文件的拥有权。mysql_install_db脚本能刷新授权表
# cd /usr/local/mysql
# chown -R mysql .
# chgrp -R mysql .
# scripts/mysql_install_db --user=mysql
# chown -R root .
# chown -R mysql data

可选命令，配置文件位置更改，且内有五种配置模式。
# cp support-files/my-medium.cnf /etc/my.cnf
# bin/mysqld_safe --user=mysql &
可选命令，自启动脚本，可以mysql自动启动。
# cp support-files/mysql.server /etc/init.d/mysql.server

遇到的问题：
----------------------------------------------------------

-- MySQL 5.5.9

-- Could NOT find Curses (missing: CURSES_LIBRARY
CURSES_INCLUDE_PATH)

CMake Error at cmake/readline.cmake:82 (MESSAGE):

Curses library not found. Please install appropriate
package,remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu , package name
is libncurses5-dev,on RedHat and derivates it is ncurses-devel.

Call Stack (most recent call first):

cmake/readline.cmake:126 (FIND_CURSES)

cmake/readline.cmake:216 (MYSQL_USE_BUNDLED_LIBEDIT)

解决：安装ncurses-devel，并删除当前目录CMakeCache.txt(必须删除，否则报错依旧)并重新运行。

开启mysql：
cd . ; ./bin/mysqld_safe &
当然你用root命令开启的时候，应当使用--user参数，这样才是安全的启动方式。
cd . ; ./bin/mysqld_safe --user=mysql &

为root和你的用户名设置密码，这需要在你先启动mysql的基础上，否则会报错，说你没有连接到端口：
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h YourusernamE password
'new-password'
也可一用下命令替代：
./bin/mysql_secure_installation
