Configure Apache Based DNF/YUM Server in RHEL 8 (CentOS8) | Setup Web DNF Repository | Nehra Classes

December 23, 2020

Configure an Apache-Based YUM/DNF repository on RHEL 8 (CentOS 8):
==
Step 1: Mount the Red Hat Enterprise Linux 8 media
# mount /dev/cdrom /mnt

Step 2: Create a local YUM repository from the mounted media

Move the existing repo files located in /etc/yum.repos.d:
# mv /etc/yum.repos.d/*.repo /tmp/

Create a directory for the repo:
# mkdir /local_repo

Create the new local repository’s configuration file, local-dvdrom.repo, under the /etc/yum.repos.d directory and set the permissions:
# touch /etc/yum.repos.d/local-dvdrom.repo
# chmod u+rw,g+r,o+r /etc/yum.repos.d/local-dvdrom.repo

Step 3: Copy media content to the local directory

Copy the ISO files locally under the /local_repo directory:
# cd /mnt
# tar cvf – . | (cd /local_repo/; tar xvf -)

Verify that the files were copied using:
# ls -l /local_repo/

Step 4: Configure the local YUM/DNF repository

Edit the repo configuration file we created earlier:
# vim /etc/yum.repos.d/local-dvdrom.repo
[LocalRepo_BaseOS]
name=LocalRepo_BaseOS
metadata_expire=-1
enabled=1
gpgcheck=1
baseurl=file:///local_repo/BaseOS/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[LocalRepo_AppStream]
name=LocalRepo_AppStream
metadata_expire=-1
enabled=1
gpgcheck=1
baseurl=file:///local_repo/AppStream/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

Check the Repository:
# yum repolist

Install the required packages for creating, configuring and managing the local repository:
# yum install createrepo yum-utils

Finally, run the createrepo command:
# createrepo /local_repo/

Step 5: Test and verify your local repository

In this step, you clean up the temporary repository files and verify that the local repository is enabled:
# yum clean all
# yum repolist

Verify that the local repository was created:
# ls /local_repo/repodata/

Disable Subscription Warning:
# vim /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=0

Install Apache:

To install the httpd (Apache) package using YUM:
# yum install httpd

Once Apache is installed, start and enable the httpd service to auto-start at boot and verify its status using the following commands:
# systemctl start httpd
# systemctl enable httpd

Check the Status:
# systemctl status httpd

Configure the firewall so that Apache can be reached:
# firewall-cmd –zone=public –permanent –add-service=http
# firewall-cmd –zone=public –permanent –add-service=https
# firewall-cmd –reload

You can now verify that your Apache server is up and running by going to the localhost URL on your web browser.
The default Apache web page http://192.168.1.109/

To configure Apache, open the configuration file:
# vim /etc/httpd/conf/httpd.conf
DocumentRoot “/local_repo”
Directory “/local_repo”
Options All Indexes FollowSymLinks
AllowOverride None
Require all granted
/Directory

Now, start the Apache service again and test its status:
# systemctl restart httpd
# systemctl status httpd

Remove the welcome page so you can serve the repo files:
# rm -rf /etc/httpd/conf.d/welcome.conf

Test httpd and restart Apache:
# httpd -t

Change permissions and set SELinux:
# setfacl -R -m u:apache:rwx /local_repo/

Check if SELinux is enforcing:
# getenforce

If it is Enforcing, type:
# chcon -Rt httpd_sys_content_t /local_repo/

If SELinux is not set to Enforcing, then the files will not serve from the repo.
# setenforce enforcing
———–

Set up the client:
Now, to configure the Red Hat Enterprise Linux 8 client machine’s repository.

Add the repo
On the client machine, add the local repos from the server to the client’s YUM configuration:
# vim /etc/yum.repos.d/local-rhel8.repo
[LocalServerRepo]
name=LocalServerRepo
enabled=1
gpgcheck=0
baseurl=http://192.168.1.109

Verify the configuration:
# yum repolist

Test the LocalServerRepo by installing a package.
# yum install vsftpd -y

Note: Add square brackets in httpd.conf directory.
