linux上mysql5.5.8安装详解

MySQL5.5源码安装和以前的5.x有区别，5.x使用autotool编译，新版的5.5使用CMake编译

1.1. Cmake的安装

http://www.cmake.org/cmake/resources/software.html

下载源码包，安装cmake方法和其他的安装相同，解压，配置，编译，安装
cmake安装

1 [root@woyoo software]# tar zxvf cmake-2.8.3.tar.gz
2 [root@woyoo software]# cd cmake-2.8.3
3 [root@woyoo cmake-2.8.3]# ./configure
4 [root@woyoo cmake-2.8.3]# make
5 [root@woyoo cmake-2.8.3]# make install

建立用户和目录

1 [root@woyoo app]# groupadd mysql
2 [root@woyoo app]# useradd -g mysql mysql
3 [root@woyoo app]# groupadd www
4 [root@woyoo app]# useradd -g www www
5 [root@woyoo app]# mkdir -p /app/www
6 [root@woyoo app]# mkdir -p /app/mysql/data
7 [root@woyoo app]# chown -R mysql.mysql /app/mysql/data
8 [root@woyoo app]# chown -R www.www /app/www

注意：

1 [root@woyoo support-files]# ls *.cnf
2 my-huge.cnf  my-innodb-heavy-4G.cnf  my-large.cnf  my-medium.cnf  my-small.cnf

下面的配置过程中，ls一下你会看到有下面的文件： my-huge.cnf 【对应1-2G内存】、my-large.cnf 【对应512M内存】、my-medium.cnf 【对应128M内存】、my-small.cnf 【对应64M或更低】，你可以查看这些文件，参照你的电脑配置，选择一个文件
