  .获得MySQL

  首先必须下载MySQLMysql的官方网站是:www.mysql.com,在中国的镜像是:www.freecode.net.cn或者:http://www2.linuxforum.net/,可以下载MySQL的稳定版本3.22.32(截止到笔者发稿为止)。其版本名称是mysql-shareware-3.22.32-win,不但免费而且没有所谓的"30天使用期限"。

  二.MySQL的安装

  ()在Win98/Winnt下的安装

  到一个目录,运行Setup程序,会提示整个安装的过程。它默认安装到c:mysql下,如果要安装到其它目录下还有改动一些东西,作为初学者,可以先不管,以默认的目录安装。好了,安装后,进入c:mysqlin目录下,运行mysqld-shareware.exe文件在Win98下直接运行,正常情况下,没有什么提示信息。

  1。将下载后的文件解压解压到一个临时目录。

  2。点击setup.exe安装到c:mysql(默认)。

  3。将mysql_example.cnf拷贝到c:my.cnf,把文件中的#basedir=d:/mysql/改为basedir=c:mysql

  4。进入msdos,到目录c:mysqlin。

  5。输入mysqld-shareware -install,此为启动Mysql数据库服务。

  6。mysqladmin-u root -p password新密码,此为修改root用户的密码(原来默认的密码为空。)

  7。输入mysql -u root -p。

  8.接着,根据提示输入新密码,正常情况下会出现几行提示信息并出现提示符号:

    Welcome to the MySQL monitor. Commands end with ; or g.

    Your MySQL connection id is 6268 to server version: 3.22.32

    Type 'help' for help.

    mysql>

  到此,你已经成功安装了MySQL
