How to upgrade PHP and MySQL in CentOS system _linux

Using Yum to update PHP, you can do it with just one command:

Copy Code code as follows:

#yum Update php

But the problem is, after using this command, the system tells me that no updatable packages have been found. The current version of PHP is only 5.2.1,php official has been updated to 5.2.6.
After some inquiries, just know that the original CentOS system source PHP is still 5.2.1, need additional sources to upgrade PHP.
According to the introduction of foreign netizens, ice ancient added an additional source:
After you log in to SSH, run the following commands in turn:

Copy Code code as follows:

#rpm –import Http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
#vi/etc/yum.repos.d/utterramblings.repo #文中这里是使用nano, but VPS can not start the Nano, with VI is also possible to replace

In the open document, add the following:

Copy Code code as follows:

[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

Similarly, run the following command to upgrade MySQL

Copy Code code as follows:
