准备工作：
新建用户和用户组
groupadd mysql
useradd -g mysql mysql
1：下载：
bison-2.4.2.tar.bz2
cmake-2.8.3.tar.gz
make-3.82.tar.gz
bzr-2.3b5.tar.gz
mysql-5.5.8.tar.gz
2：解压安装前3个包
tar zxvf cmake-2.8.3.tar.gz
cd cmake-2.8.3
./configure
make
make install
tar zxvf make-3.82.tar.gz
cd make-3.8.2
./configure
make
make install
tar jxvf bison-2.4.2.tar.bz2
cd bison-2.4.2
./configure
make
make install
3：解压mysql-5.5.8.tar.gz
tar zxvf mysql-5.5.8.tar.gz
cd mysql-5.5.8
cmake . \
-DCMAKE_INSTALL_PREFIX=/mysql/mysqldir \
-DMYSQL_DATADIR=/mysql/mysqldir/data \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR==/mysql/mysqldir/data/mysql.sock \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0
报错(如无报错直接make & make install 即可)：

-- Configuring incomplete, errors occurred!
缺少包：ncurses-devel
解决：
到安装光盘或者网上DOWN相应的包
安装：
rpm -ivh ncurses-devel*.rpm
rm -f CMakeCache.txt
cmake . \

make
make install
完成后进入MYSQL安装目录
cd /mysql/mysqldir
cp support-files/my-huge.cnf /etc/my.cnf
vi /etc/my.cnf
将数据目录和套接字文件修改为实际值.
修改权限
chown mysql:mysql /etc/my.cnf
chown -R mysql:mysql /mysql/mysqldir
切换用户进入安装目录
su - mysql
cd /mysql/mysqldir
cp scripts/mysql_install_db .
./ mysql_install_db
启动MYSQL
bin/mysqld_safe &
OK
