How do I upgrade php version?

[webfeatus]

Using php 5.2.17-1.el5.art
What is the safest way for me to upgrade?
Without upgrading anything else?
CentOS release 5.8 (Final) - i686 - 2.6.18-128.2.1.el5.028stab064.8PAE

well, basically it's not that difficult but every installation is different.
A short summary is here:
https://www.atomicorp.com/wiki/index.php/PHP

Bes thing to do in such cases is to have a test environment. I have one too.
And since you only have one server it's not like others having dozens or hundreds of different servers/configs.
I would suggest you the following.
Install VMWare Workstation(with costs) or VMWare Player (free) or SUN/Oracle VirtualBox (free)
After that you make a complete backup of your server via tar. similar to this:
mkdir backups
cd backups

Code: Select all

tar -cvpf /backups/fullbackup.tar --directory=/ --exclude=proc --exclude=sys --exclude=dev/pts --exclude=backups 

After that setup/install a vanilla virtual server the same you did with your rootserver
make a snapshot of it
and than restore/extract your backup.
Of course its not that easy.
When restoring into virtual server pay attention to the boot and harddisk related files and settings.

at the end it will pay out.
start with it and if you face problems just post exactly what you did and the error is.
When you test environment is setup you can try upgrading php on your testbox and see how everything is going.
ask question, get answers, test them and when everything is running in your testbox you can touch your livebox.

Unfortunately, I cannot complete the process above.
I operate two servers but I simply do not have the time to do things the way you indicate.
Plus, this opens doors to a world of stuff that I do not have time to learn.

I have attempted to install the atomic repo:

Code: Select all

Do you agree to these terms? (yes/no) [Default: yes] yes
Configuring the [atomic] yum archive for this system
Installing the Atomic GPG key: OK
The Atomic Rocket Turtle archive has now been installed and configured for your system
The following channels are available:
  atomic          - [ACTIVATED] - contains the stable tree of ART packages
  atomic-testing  - [DISABLED]  - contains the testing tree of ART packages
  atomic-bleeding - [DISABLED]  - contains the development tree of ART packages

But /etc/yum.repos.d does not list the atomic repo?

[webfeatus]

I still seem to have the same problem, as mentioned above, when attempting to install the atomic repo.

Here is my current daily output

Code: Select all

yum update does not see any packages for php

Try running the installer again, I added a check to see if it was installed but removed.

[webfeatus]

The installer finally worked, thank you.

Now looking into his issue: https://www.atomicorp.com/forum/viewtop ... +optimizer

[scott]

Zend Optimizer was discontinued, and it is no longer supported. You have to migrate your sites to zend loader (which requires a key).

[webfeatus]

Is there a command I can run which will check if any of my customers have applications running that require zend optimizer?

If you care about having properly managed servers, but don't have they time to do it yourself, I'd recommend asking a good management company to take care of it.

Should I be concerned about these warnings received during php & mysql update?

Looks like you've got some PHP modules installed (either packaged or built from source?) that were built for another PHP API version, so they won't work with your current PHP install.

[webfeatus]

Any advice on how I handle the problems?

[breun]

Do you know if you built modules from source? What PHP packages do you have installed? Do you need these modules? So many questions, not too easy to help via a forum like this.

UPGRADED:
PHP Version: 5.3.21
MYSQL Version: 5.5.29-cll

Here is one client who is going to be upset.
http://www.baliauthentique.com = OK
But a sub pages like this:
http://www.baliauthentique.com/Demandez ... ntique.php
Oh well, before the upgrade I had already commenced an email about his coding techniques.
I guess I will be adding more information to that email.

I assume that this is what you are talking about?

Directive 'safe_mode' is deprecated in PHP 5.3
- Fixed

Modules:
ssh2
- I know that this is required for Plesk 11 upgrade.
- But I have no knowledge except it looks important
dbase
- http://php.net/manual/en/book.dbase.php
- I can ask my programmer if I need this
mysql
- What a screamer!
- I believe that I have this working to a certain degree but I am confused by this one
- ASL-WEB is broken and issue being discussed with support.
pdo_mysql
- http://php.net/manual/en/ref.pdo-mysql.php
- I can ask my programmer if I need this
Dynamic Library:
/usr/lib/php/modules/mysqli.so
- exists on the the server
- /usr/lib/php/modules/mysqli.so is the correct location
- reference from my php.ini
