一台装有RHEL 7.0操作系统的电脑
把光盘设备中的系统镜像挂载到/media/cdrom目录：[root@linuxprobe ~]# mkdir -p /media/cdrom [root@linuxprobe ~]# mount /dev/cdrom /media/cdrom mount: /dev/sr0 is write-protected, mounting read-only
使用Vim文本编辑器创建Yum仓库的配置文件，下列具体参数含义可参考4.1.4小节：[root@linuxprobe ~]# vim /etc/yum.repos.d/rhel7.repo [rhel7] name=rhel7 baseurl=file:///media/cdrom enabled=1 gpgcheck=0
接下来就要试试动手安装Apache服务程序啦，需要注意使用yum命令安装软件时后面写的是服务程序的名字，而apache服务的软件包名称叫做httpd，直接执行yum install apache命令则是会报错误的。[root@linuxprobe ~]# yum install httpd Loaded plugins: langpacks, product-id, subscription-manager ………………省略部分输出信息……………… Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: httpd x86_64 2.4.6-17.el7 rhel 1.2 M Installing for dependencies: apr x86_64 1.4.8-3.el7 rhel 103 k apr-util x86_64 1.5.2-6.el7 rhel 92 k httpd-tools x86_64 2.4.6-17.el7 rhel 77 k mailcap noarch 2.1.41-2.el7 rhel 31 k Transaction Summary ================================================================================ Install 1 Package (+4 Dependent packages) Total download size: 1.5 M Installed size: 4.3 M Is this ok [y/d/N]: yDownloading packages: -------------------------------------------------------------------------------- ………………省略部分输出信息……………… Complete!
把httpd服务程序启动并加入到开机启动项中，让Web服务程序能够随系统开机而启动运行：[root@linuxprobe ~]# systemctl start httpd [root@linuxprobe ~]# systemctl enable httpd ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'当各位同学们打开火狐浏览器后键入http://127.0.0.1，如图10-3所示，然后就可以看到httpd服务网站的默认页面啦~[root@linuxprobe ~]# firefox
