linux内核版本:
#uname -r
2.6.32-220.7.1.el6.centos.plus.x86_64
需要的软件:
cmake-2.8.5.tar.gz
mysql-5.5.22.tar.gz 
 
因为mysql5.5是通过cmake编译器进行编译所以安装mysql5.5时先安装cmake
#yum -y install  ncurses-devel  *gcc*  *make*
 
安装cmake:
wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz
#tar -zxvf  cmake-2.8.5.tar.gz
#cd cmake-2.8.5
#./bootstrap
#make && make install

 
安装mysql:
到官方网站下载mysql最新版本:
我这下载的是目前最新的
#tar -zxvf mysql-5.5.22.tar.gz 
#cd mysql-5.5.22
// 详细参数请参考:http://blog.wqgcool.com/?p=677

#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql5\ 

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql5 \

-DEXTRA_CHARSETS=all

 
#make && make install

 
//如果要重新牌子请执行:
#rm -rf CMakeCache.txt
#make clean  all

配置mysql5:
# pwd
/usr/local/mysql5
#cp support-files/my-medium.cnf /etc/my.cnf 
//创建mysql配置文件

 
//开机启动
# pwd
/usr/local/mysql5
#cp support-files/mysql.server /etc/init.d/mysql
#chkconfig --add mysql
初始化数据库:
#chown -R mysql  /usr/local/mysql5/
#chown -R mysql:mysql /usr/local/mysql5/data
# /usr/local/mysql5/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql5 --datadir=/usr/local/mysql5/data 
//操作这一步可能会报错,所以在编译的时候最好少添加点参数。如过和我一样是菜鸟的话!
 
#service mysql start
# chkconfig mysql on
#ps -e | grep mysql
5722 pts/0    00:00:00 mysqld_safe
5974 pts/0    00:00:00 mysqld
 
设置mysql的PATH路径
#export PATH=$PATH:/usr/local/mysql5/bin/
#echo "PATH=$PATH:/usr/local/mysql5/bin/" >> /etc/profile
//永久生肖
 
登录mysql
#mysqladmin -u root password wdmysql
输入密码:
mysql> status;
