What Can I Do If the Download Speed Is Slow After the yum makecache Command Is Executed?

Symptom

After the yum makecache command is executed to create a local cache, the download speed becomes slow.

Solution

Configure the EPEL source.

• Learn what is EPEL source.
• EPEL repository: https://repo.huaweicloud.com/epel/

Constraints

The operations described in this section apply to x86_64 ECSs.

Procedure

1. Run the following commands to back up configuration files:

   cp -a /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup

   mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup

2. Modify the epel.repo file.

   Run the following commands to uncomment the line starting with baseurl, comment out the lines starting with mirrorlist, and replace http://download.fedoraproject.org/pub in the file with https://repo.huaweicloud.com, respectively:

   sed -i "s/#baseurl/baseurl/g" /etc/yum.repos.d/epel.repo

   sed -i "s/metalink/#metalink/g" /etc/yum.repos.d/epel.repo

   sed -i "s@http://download.fedoraproject.org/pub@https://repo.huaweicloud.com@g" /etc/yum.repos.d/epel.repo

3. Run the yum update command to update the software list.
   

   • After you execute the yum makecache command, if the system displays the message "Another app is currently holding the yum lock", run the rm -rf /var/run/yum.pid command to delete the yum.pid file. Then, run the yum makecache command again to generate the cache.
   • After you execute the yum makecache command, if the system displays the message "Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again", run the following command to update the certificate and temporarily disable the EPEL image source:

     yum --disablerepo=epel -y update ca-certificates

   • If certain packages are unavailable, this issue may be caused by in-progress data synchronization. In this case, try again after a few hours.
