centos5.4系统中下载和安装mysql5.0.77（系统中已经自带包含安装包）

1. 首先配置一下 yum 的源，指向光驱。

(1) 光驱中放入系统盘

(2) mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom

(3) 备份一下 yum 原始配置:

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

(4) 修改配置 vim /etc/yum.repos.d/CentOS-Base.repo

在文件末尾添加如下内容：

Centos-base.repo代码



[DVDROM]
name=myyum
baseurl=file:///mnt/cdrom/
gpgcheck=0
enabled=1

[DVDROM]name=myyumbaseurl=file:///mnt/cdrom/gpgcheck=0enabled=1

好了，配置完成。

2. 使用 yum 命令安装 mysql

yum groupinstall mysql （此命令可以在电脑联网的情况下，不使用光驱进行网络下载和自动安装所有依赖包和主程序，安装的是官方提供的最新版本，对于版本号可以在过程当中发现。此次实验发现使用的是mysql5.0.77 是latest最近的版本）

分析完后，有个下载询问， 更新一点内容，内容不大。输入 y [回车]

mysql就自动装好了， 太方便了。

3. 查看一下有没有mysql服务

chkconfig --list | grep mysql

mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off

4. 启动mysqld

/etc/init.d/mysqld start

starting MySQL: [ok]

5. 修改root账号密码

mysqladmin -u root password '123456'

6. 连接到mysql

mysql -u root -p

输入密码

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

Your MySQL connection id is 4

Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

此次实验自动下载和安装过程：

[root@localhost init.d]# yum groupinstall mysql
