一. linux用 wget 下载需要的软件，保存到目录 /usr/local/src 下
wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.5/mysql-5.5.20.tar.gz
wget http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz
wget http://ftp.gnu.org/gnu/bison/bison-2.5.tar.gz
二. 安装 cmake
cd /usr/local/src
tar zxvf cmake-2.8.7.tar.gz
cd cmake-2.8.7.tar.gz
./bootstrap
gmake
gmake install
cd ../
tar zxvf bison-2.5.tar.gz
cd bison-2.5
./configure
make
make install
cd ../
三. 编译安装 MySQL 5.5.20
groupadd –g 1000 mysql
useradd –u 1000 –g mysql mysql
tar xvf mysql-5.5.20.tar.gz
cd mysql-5.5.20/
/usr/local/bin/cmake .
