二进制包安装mysql5.5.32(免编译)文件名：
mysql-5.5.32-linux2.6-x86_64.tar.gz
#cp mysql-5.5.32-linux2.6-x86_64.tar.gz /usr/local/src
#mv mysql-5.5.32-linux2.6-x86_64.tar.gz mysql-5.5.32-bin
#mv mysql-5.5.32-bin /usr/local/
初始化数据库：
#useradd mysql -s /sbin/nologin -M
#chown mysql.mysql -R /usr/local/mysql-5.5.32-bin
#cd mysql-5.5.32-bin/scripts/
#mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.5.32-bin/ --datadir=/usr/local/mysql-5.5.32-bin/data/
#cp support-files/mysql.server /etc/init.d/mysqldbin
#chmod 755 /etc/init.d/mysqldbin
vim /etc/init.d/mysqlbin
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.
#添加基目录和数据目录
basedir=/usr/local/mysql-5.5.32-bin
datadir=/usr/local/mysql-5.5.32-bin/data
# Default value, in seconds, afterwhich the script should timeout waiting
# for server start.
# Value here is overriden by value in my.cnf.
#cp support-files/my-medium.cnf /etc/my.cnf #这步不是必需的
启动数据库：
[root@node1 bin]# /etc/init.d/mysqldbin start
