yum –y install gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml*
ncurses-devel libmcrypt* libtool-ltdl-devel* bison
[备注：如果有了就不用安装了，可以用rpm -qa | grep name检查一下]
,创建mysql安装目录
# mkdir -p /usr/local/webserver/mysql/
,创建数据存放目录
# mkdir -p /data/mysql/
,创建用户和用户组与赋予数据存放目录权限
# groupadd mysql
# useradd -g mysql mysql
# chown mysql.mysql -R /data/mysql/
,安装cmake（mysql5以后是通过cmake来编译的）
# wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz
# tar zxvf cmake-2.8.4.tar.gz
# cd cmake-2.8.4
#.configure
# make && make install
,下载解压mysql 
# wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.19.tar.gz
# tar zxvf mysql-5.5.19.tar.gz
# cd mysql-5.5.19

,复制配置文件
[[email protected]]# cp support-files/my-medium.cnf /etc/my.cnf
[[email protected]]# cp support-files/mysql.server /etc/init.d/mysqld
[[email protected]]# chmod  /etc/init.d/mysqld
,初始化数据库
bash scripts/mysql_install_db --user=mysql --basedir=/usr/local/webserver/mysql --datadir=/data/mysql/
,启动mysql服务
[[email protected] mysql-]# /etc/init.d/mysqld start
,启动完成之后用ps -ef |grep mysql 命令查看是否启动
,/usr/local/webserver/mysql/bin/mysql -u root -p
通过命令行登录管理MySQL服务器 初始密码为空
,修改root密码
mysql>use mysql ;
mysql> update user set password=PASSWORD("123456") where user='root';
mysql> FLUSH PRIVILEGES;
#或
$ bin/mysqladmin -u root password '123456'


cat /usr/local/mysql/bin/mysqlbug | grep CONFIGURE_LINE
