首先去http://dev.mysql.com/downloads/mysql/5.5.html#downloads站点下载:
分别下载以下三个文件(由于我的机器是32位,下面是32位版本的包,如果你的机器是64位的请下载64位版本):
MySQL-server-5.5.16-1.rhel5.i386.rpm
MySQL-client-5.5.16-1.rhel4.i386.rpm
MySQL-devel-5.5.16-1.rhel4.i386.rpm
使用wget命令使用断点传输的方式将这三个文件下载
wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/
下载完成后开始安装:
rpm -ivh MySQL-server-5.5.16-1.rhel4.i386.rpm MySQL-client-5.5.16-1.rhel4.i386.rpm MySQL-devel-5.5.16-1.rhel4.i386.rpm
提示安装完成后,输入mysql 看是否安装成功
mysql
如果出现如下错误信息:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
说明mysql服务还没有启动,输入service mysql start启动mysql服务
service mysql start
然后再输入mysql,若出现以下提示信息,说明成功。
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1

首次安装时,默认密码为空,可以使用如下命令修改root密码,
mysqladmin -u root password mypassword
mypassword 为你设定的新密码
然后再次登录
mysql -u root –p
rpm包安装的MySQL是不会安装/etc/my.cnf文件的,解决方法,只需要复制/usr/share/mysql目录下的my-huge.cnf 文件到/etc目录,并改名为my.cnf即可
cp /usr/share/mysql/my-huge.cnf /etc/my.cnf
配置远程访问
处于安全考虑,Mysql默认是不允许远程访问的,可以使用下面开启远程访问
//赋予任何主机访问数据的权限
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION
//使修改生效
mysql>FLUSH PRIVILEGES
如果依然不能远程访问的话,那就很可能防火墙的原因了,可以在防火墙中开启3306端口或者干脆关掉防火墙。
