mysql 最新的版本都需要cmake编译安装，估计以后的版本也会采用这种方式，，所以特地记录一下安装步骤及过程，以供参考。
注意：此安装是默认RedHat下已经安装了最新工具包，比如GNU make, GCC, Perl, libncurses5-dev，如果在编译安装过程中发现有缺失的工具包，先yum install 单独下载安装再继续即可。

RedHat Linux 2.6.18下安装MySQL 5.1.7及Navicat 8 见redhat9下安装mysql-4.0.26记 见
RedHat下MySQL 5.6 安装、维护 见
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
wget
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 .
