This article focuses on "how to use YUM to upgrade PHP and MySQL under CentOS". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to upgrade PHP and MySQL under CentOS with YUM.

Yum is a tool that comes with CentOS system to easily add / delete / update RPM packages. It can automatically solve the problem of package dependency.

Updating PHP with yum can be done with a single command:

# yum update php

But here's the problem. After using this command, the system told me that no updatable packages were found. The current version of PHP is only 5.2.1 PHP has been officially updated to 5.2.6.

After some inquiry, I learned that the source PHP of the original CentOS system is still 5.2.1, and additional sources are needed to upgrade PHP.

According to foreign netizens, Binggu added additional sources:

After logging in to SSH, run the following commands:

# rpm-- import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

# vi / etc/yum.repos.d/utterramblings.repo #

Nano is used here, but VPS cannot start nano, and it is possible to use vi instead.

Add the following to the open document:

[utterramblings]

Name=Jason's Utter Ramblings Repo

Baseurl= http://www.jasonlitka.com/media/EL$releasever/$basearch/

Enabled=1

Gpgcheck=1

Gpgkey= http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

Save.

Run the following command again to complete the upgrade of php

# yum update php

Similarly, run the following command to upgrade mysql

# yum update mysql
