Configure the website service program first

Step 1: Mount the system image in the CD-ROM device into the / media/cdrom directory.

[root@LinuxLehehe ~]# mkdir -p /media/cdrom
[root@LinuxLehehe ~]# mount /dev/cdrom /media/cdrom
mount: /dev/sr0 is write-protected, mounting read-only

Step 2: Create configuration files for Yum repository using Vim text editor

[root@LinuxLehehe ~]# vim /etc/yum.repos.d/rhel7.repo
[rhel7]
name=rhel7
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0

Step 3: Start installing Apache service program. Note that when installing with the yum command, the package name of the Apache service following the command is httpd. If the yum install apache command is executed directly, the system will report an error.

[root@LinuxLehehe ~]# yum install httpd
Loaded plugins: langpacks, product-id, subscription-manager

Step 4: Enable the httpd service program and add it to the boot startup item to enable it to run with the system boot, thus continuing to provide Web services for users:

[root@LinuxLehehe ~]# systemctl start httpd
[root@LinuxLehehe ~]# systemctl enable httpd
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.
target.wants/httpd.service'

When everything is ready, you can start demonstrating static web pages.

After doing this, refresh the httpd service program in Firefox browser, and you can see that the content of the first page of the program has changed, as shown in Figure 10-5.

[root@LinuxLehehe ~]# echo "Welcome To LinuxProbe.Com" > /var/www/html/index.html
[root@LinuxLehehe ~]# firefox
