Php 4 to Php 5 upgrade

[bonjurkes]

Hello,

I have a question about upgrading php 4 to php 5 using yum update. I have centos 4.5 server. And i asked at their support forums as how can i upgrade to php 5 using yum update. Because i heard that php 4 support will be over at end of the year. And they give me a command like

yum enablerepo=centosplus update php

But i am not sure if it is a good idea to update php using centosplus repo, because i had some problems about using other repos for updating software.

So i have 2 questions,

Is it safe to upgrade php like the way i told above ?

If it is safe, is there a way to mess up plesk by updating php by this method.

Or i will be glad if anyone can tell a safe method to updating php.

Hi

You can upgrade PHP safely the described way. Also instead of centos repository it is possible to use the packages from atomicrocketturtle: http://www.atomicrocketturtle.com/

Plesk works with PHP 5 without problems. Do not forget to update the PHP modules and extensions as well.

how can i update php modules and extensions?

Because i was just planning to do as i explained above. What else should i do?

 

[Monica@]

yum update php php-gd php-mysql php-imap
and so on, it depends on which modules you have installed,
generally with "yum" all the dependencies should be resolved automatically.

this is the error i get after the above command

Error: Missing Dependency: php <= 4.4.0 is needed by package php-sqlite2
Error: Missing Dependency: php = 5.1.6-1.2.1.centos is needed by package php-xml

I guess i am using php 4.3.9 , i always use yum update but it never updated php 4.4.0

and i didnt understand the 2nd missing dependency. I guess it requires centos5, but i read that its possible to update php 5 without updating to centos 5 also.

It is the dependencies issue. Include php-xml and php-sqlite2 in the list of updates.
You can get to know the current version installed with
php -v

Most probably you have CentOS repository configured that is why you see the

php -v

When i included php-xml and php-sqlite2 it also gives the same dependency error.

and i check the link, there is a problem that i dont know,

[root@server ~]# wget -q -O - http://www.atomicorp.com/installers/atomic.sh |sh

When i say --enablerepo=atomic, it says

I dont know what is the problem now

Is that a CentOS 4 VPS? You should have 2 channels by default (base and updates), and atomic would be the third. That output isn't displaying any channels.
