Topic: Re-Add PHP4 to an updated PHP5 installation

[magwm]

Hello!

I have installed SME server from the 7.1 CD and added the php5 + mysql 5 from centos, in order to install a Wikimedia WIKI.

Everything works quite nicely (wiki is already in production), but now I must install a CMS which is not PHP5-compatible. (in order to merge our website server which is an old fedora..)

Is it possible to re-add php4, and how? and how can I tell apache to use php5 for the wiki and php4 for the other ibay?

I am quite at a loss and would appreciate any help and indications..

thanks, Michel

I think that will be a pretty hard one. I do not know if it possible to run both versions from RPM as they will probably use configuration fragments that are the same, as well as share a single configuration file.

First step you should do I guess is try and rename all the template entries in the tree where the folder is php to php5, expand the template to create a php5 configuration file, reinstall php4 and then figure out if it is possible to run two versions of php in a single Apache instance, as I am not so sure if that will work.

A little google-ing gave me this result: http://wiki.coggeshall.org/37.html

I believe that the proxy module is already implemented and loaded into SME Server (not in the opportunity to check that right now), so I guess the only thing that needed to be done is create a new virtual server and try to have it run php4 instead of php5 (after you have succesfully managed to install them both following the track I set out in my earlier post).

Hmmm....

1. Go back to php4/mysql4 and run mediawiki 1.6

2. Go back to php4/mysql4 and run php5 as cgi. Search the forums.

3. Install vmware-server and run another copy of sme in server only mode and   use proxypass.

hmm. this is going to be a fun-stopper..

I sure can't go back to mediawiki 1.6 now! it was a pain to install all parts and making it work properly, + I have hundreds of screenshots in it.. I doubt if the updated database is compatible with 1.6? the 1.10 version info says it's not

Can't php4 be installed as cgi? like the howto that shows how to install php5 as cgi.. it seems strange to me that php4+php5cgi is possible but not the reverse..

I don't think the server has enough balls (P4/1GbRAM/20GbHD) to run a vm with another SME7..(?)  but I could try, if there is a smeserver-vmware somewhere. . . hmm I see a loooong thread on installing vmware..

btw mysql 5 is ok for the cms I need, it's more a php/sessions thing I think (IANAPhpProgrammer) (actually its only the config part of the cms that doesnt do it's job..)

Regretfully I have not many resources to spend on this, in any case I don't want to break the system as it is in production..  I will just stick with the old web server if this is all impossible!

has someone further advice on how to proceed? thanks!

There have been a few advises already... how did you do with them? Did you already try them? Do not expect an out-of-the-box solution for a problem like this...

Hello, cactus,

this server is in production already for some time, working as a nice wiki and mail server.  it's sending mail for 20 users so I can take it down only for short times.

However, I can't take down the wiki so I can't switch back to php4

the 20gb disks preclude large VM's, plus during active hours the server is quite loaded and wouldn't like a second OS serving our main website.

all in all, the only thing possible seems to install php4 as cgi, but I don't know how to do that. compiling from source perhaps?

ciao, Michel

If anyone can give me a more or less complete trail on how to compile a php4-cgi rpm for sme7.2, I will do it and provide a more complete howto..

ciao, Michel
