Installing PHP5

Using DreamHost's PHP 5

PHP 5 was added to all plans by DreamHost as of June 2005. As of September 2008, support for PHP4 was discontinued, so you can no longer switch back to PHP 4 from PHP 5 from the panel.

If you haven't switched to PHP 5 yet, you can do this in the Control Panel. But, again, you will not be able to switch back to PHP 4 after switching to PHP 5.

Here's how to switch from PHP 4 to PHP 5:

  1. Log into the DreamHost Control Panel.
  2. Click Domains, then Manage Domains.
  3. Click the wrench icon next to the domain you want to activate PHP 5 on (under the Web Hosting column).
  4. Select PHP 5.x.x from the dropdown menu.
  5. Click Change fully hosted settings now! at the bottom of the section.
  6. Repeat steps 3-5 for each additional domain you want to activate.

It will take a few minutes for the changes to take effect.

To see information about which version of PHP you have installed, make a simple file with the following content: 

<?php  
   phpinfo();
?>

Save it in your web hosting directory as, e.g. version.php. Then load this file from your web browser. The resulting page should have your PHP version in large letters at the top, for instance "PHP Version 5.2.6". Below that will be lots of detail about your PHP installation.

DreamHost provides PHP 4 and PHP 5 PHP-CLI binaries which are available for use from the shell commanded line. The paths for the default DreamHost PHP-CLI installed binaries are as follows:

  • PHP 4 - /usr/local/bin/php
  • PHP 5 - /usr/local/php5/bin/php

You can confirm the exact version numbers in use by executing the selected binary from within the shell using the "-v" option, which will run the binary and return the version information.

If you've previously installed your own copy of PHP (for example, by following the instructions below), you'll also need to remove the appropriate AddHandler and Actions directives from your .htaccess file.

If you're using DreamHost's installed PEAR modules, make sure you watch out for this: PEAR breaks on upgrading to PHP5.

Some PHP applications like MediaWiki includes scripts that must be executed from the shell account, and since version 1.7 MediaWiki requires PHP 5.x. PHP5 can be used from: 

/usr/local/dh/cgi-system/php5.cgi

Compiling a Customized PHP 5

The instructions provided in this article or section are considered advanced.

You are expected to be knowledgeable in the UNIX shell.
Support for these instructions is not available from DreamHost tech support.

Server changes may cause this to break. Be prepared to troubleshoot this yourself if this happens.

WARNING
If you configure your site to use your own custom PHP installation, your version of PHP will no longer automatically upgrade when DreamHost upgrades their version of PHP.
It is your responsibility to reinstall new versions of PHP! Leaving old versions of PHP installed can possibly be a security hazard!
NOTICE
This wiki contains two separate pages describing different ways to install PHP5. Before following these instructions, consider also the Advanced PHP configuration method. That method will allow you to run PHP4 and PHP5 on the same site, you can customize your php.ini, and you can configure PHP to be updated automatically. If it meets your needs it should be easier than the methods on this page.

Custom PHP 5

Note for PHP 5.2.5 - The below scripts should be modified to handle PHP 5.2.5 in the following ways: 

--with-curl-dir=/usr/local/lib => --with-curl
--with-gd-dir=/usr/local/lib => --with-gd
--with-xml => --with-libxml-dir=/usr/local/lib
--with-zip => --enable-zip
--enable-track-vars => php 5.2.4 track-vars is always enabled (--enable-track-vars removed)
--enable-memory-limit => php 5.2.4 memory-limit is always enabled (--enable-memory-limit removed)

Also, the scripts should be modified to more clearly indicate which line to comment/uncomment based on whether you will be running PHP as CGI, which is almost always the case (running as CGI).

WARNING if you use PHP 5.2.3 (and maybe others) the scripts below will copy the php binary when you need them to copy the php-cgi binary!!

Preparations

If you want to compile your own copy of PHP 5, the following script will download and compile it with some commonly-used additional extensions. You can also custom compile PHP 4. Please be aware that:

  • you need around 500Mbyte free disk space for the whole process to complete, and
  • the script can take more than an hour to complete, so don't get impatient!

Install/Compile PHP 5

  1. Copy the PHP5_installscript into a text editor and replace YOUR DOMAIN HERE on the 4th line with your site's domain name. MAKE SURE YOU USE THE SAME CASE THAT APPEARS IN THE DIRECTORY LISTING (UPPER or lower).
  2. Copy the new contents to your clipboard.
  3. Log in to your account using SSH
  4. Create a new file in your SSH by entering the command: 
    vim installscript
  5. Hit i for insert mode, then right-click to paste your clipboard (the install script) contents, then hit Esc, type :wq (that's 'colon', 'w', 'q'), and press Enter to save and exit.
  6. Make the file executable by entering the command: 
    chmod +x installscript
  7. Run the script by entering the command: 
    ./installscript
  8. After it has finished you will need to edit your htaccess file appropriately. Add the following: 
    Options +ExecCGI
AddHandler php-cgi .php
Action php-cgi /cgi-bin/php.cgi

<FilesMatch "^php5?\.(ini|cgi)$">
Order Deny,Allow
Deny from All
Allow from env=REDIRECT_STATUS
</FilesMatch>
    to a file called .htaccess and place it in the root folder of your domain you specified above (/home/YOUR USERNAME/YOUR DOMAIN HERE/.htaccess)

    9. Editing your new Php.ini file

    Your new php.ini file is located here:

    /home/YOURUSERNAME/php5/etc/php5/YOURDOMAINNAME

    To see if your site is running the new version of php. Create a file in your web root (public_html) called "phpinfo.php"

    Inside the file have the following code: <?php phpinfo(); ?>

    Now browse to that file at YOURDOMAIN.COM/phpinfo.php

    If you used the above install script - you should be running Php 5.2.0

Instructions To Add More Domains

  • Go to the domain directory where you want to use the Custom PHP5 Compile (Example: /abc.com/)
  • Type: ln -s /home/USERNAME/DOMAIN_NAME/cgi-bin /home/USERNAME/SUB.DOMAIN_NAME/cgi-bin (Replace USERNAME with your actual username, Replace DOMAIN_NAME with your actual domain name where the custom php5.cgi in stored. Example abc.com. Replace SUB.DOMAIN_NAME with the actual sub domain you want to use for the custom php5)
  • Press Enter And You Are Done.
  • Upload the .htaccess with the AddHandler/Action methods as listed above to (Example: /abc.com/)
  • Upload the same .htaccess with the AddHandler/Action methods to the subdomain (Example: subdomain.abc.com)

Notes

This script has been updated to compile both MySQL [1] and mysqli [2] libraries. mysqli is required to work with new features in MySQL 4.1.3 (client) and up. As Dreamhost is using MySQL 4.1.8 (client) and MySQL 4.0.24 (server), it is suggested to use mysqli. However, if you run into any problems compiling mysqli, feel free to remove '--with-mysqli' from the php configure line.

The complete script can also be found here: Template:PHP5_installscript (for editing)

read this first: Installing PHP5

Main PHP 5 install script

This is the "main" PHP 5 install script. (Below it is a more-recent, alternate PHP 5 install script that may help users who find that the script keeps getting automatically "killed" by DreamHost.)

This script does not work if you are compiling PHP version < 5.2.3. To make this script work when compiling PHP versions before 5.2.3, look for the line in the script that say to uncomment them and do just that. Change from: 

cp ${INSTALLDIR}/bin/php-cgi ${HOME}/${DOMAIN}/cgi-bin/php.cgi

...to this... 

cp ${INSTALLDIR}/bin/php ${HOME}/${DOMAIN}/cgi-bin/php.cgi

If your downloads fails on kent.dl.sourceforge.net, change 

wget -c http://kent.dl.sourceforge.net/sourceforge/freetype/${FREETYPE}.tar.gz

to 

wget -c http://voxel.dl.sourceforge.net/sourceforge/freetype/${FREETYPE}.tar.gz

After using this script below and not the alternate script remember to add the below or php5 dies with "malformed header from script. Bad header=" to the .htaccess file in the ${DOMAIN} directory 

Action application/x-httpd-php5 /cgi-bin/php5.cgi
AddType application/x-httpd-php5 .php5

Alternative PHP 5 install scripts

These are alternative PHP 5 install scripts created by Charles Wiltgen, who created them to work around problems he was having with an older version of the "main" PHP 5 install script.

First, run php5-install-prep.sh to download and unpack all prerequisite packages.

Then, run php5-install.sh to compile and install PHP 5 and all prerequisites.

#   - Added a couple more error-checks
#   - Replaced wget with cURL
#   - Added more to help keep it from getting killed
#   - Updated to php-5.2.3, curl-7.17.1, freetype-2.3.5 
# - Updated 2007-01-15 by Charles Wiltgen (charles@wiltgen.net)

be sure to add this to an .htaccess file: (SetEnv line added 04-25-2009. custom php.ini will not load without it - dcostalis)

if you get 500 errors, run this from the shell: 

cp ~/php5/bin/php-cgi ~/DOMAIN.TLD/cgi-bin/php.cgi

Also note that when using shell access, do not create a new shell account. Simply edit your existing username for this domain.

Possible Errors

Update to above configure command 04/21/08

I was not able to compile php5 using the script above. At first I ran into problems where it could not find header files (easy.h for example), which turned out to be that you had to use absolute paths and not ~/ for home. I also had to remove some things like calender since they are no longer options! Here is the command line that the script should probably be using:
./configure --prefix=$HOME/php5 --with-config-file-path=$HOME/etc/ --enable-fastcgi --enable-force-cgi-redirect --with-libxml-dir=$HOME/php5 --with-libxml-dir=$HOME/php5 --with-freetype-dir=$HOME/php5 --with-openssl=/usr --with-mhash=$HOME/php5 --with-mcrypt=$HOME/php5 --with-zlib-dir=$HOME/php5 --with-jpeg-dir=/usr --with-png-dir=/usr --with-gd --enable-gd-native-ttf --enable-ftp --enable-exif --enable-sockets --enable-wddx --with-iconv=$HOME/php5 --with-curl=$HOME/php5 --enable-mbstring --enable-mbregex --with-mysql=/usr --without-pear --with-gettext --with-imap=$HOME/php5 --with-imap-ssl=/usr

Step 6 Error

If you receive the error export: Command not found when you run step 6 then you are using a shell other than Bash. To get around this, follow these steps:

  1. edit the file by entering the command: 
    vim installscript
  2. hit i for insert mode, then enter the following (must be the first line): 
    #!/bin/bash
  3. then hit Esc, type :wq (that's 'colon', 'w', 'q'), and press Enter to save and exit.
  4. repeat step 6 from above.

Troubleshooting

This article or section contains conversational writing that requires cleanup.
All user comments should be confined to talk pages, and writing should not be done from the perspective of the author.
We are hoping to create articles that meet certain standards. Please discuss this issue on the talk page. Editing help is available.

If you run in trouble, try to go trough the process step by step. It's no bad idea to run "make clean" just before a "make" command. If nothing else (Google, skilled son/daughter) can help. Feel free to post your problem(s) to the discussion page.

imap-2004g Errors without SSL set up

The problems I ran into while installing both php4 and 5 was with imap-2004g. Most people don't have or need SSL installed in every directory, but if you don't have it set up you will get an error using the script above which says: 

If you get No such file error messages for files x509.h, ssl.h,
pem.h, buffer.h, bio.h, and crypto.h, that means that OpenSSL
is not installed on your system. Either install OpenSSL first
or build with command: make lnx SSLTYPE=none

So then I went into my new /home/USERNAME/source/imap-2004g directory (created by the install script) typed: 

 install clean
 make lnx SSLTYPE=none

But that didn't work because Dreamhost uses: slx. So you need to type 

 make slx SSLTYPE=none

Which is great. But then you have to go back into the install script and change the php preference references to openssl to: 

     --without-openssl \
        --without-imap-ssl"

Also take out the wgets and untarring that you've already done, save the script again and it should work for you.

UPDATE

With the new version of the alternate install script, you should be able to get by with only changing --with-imap-ssl=/usr to --without-imap-ssl but leaving the openssl alone.

Also, if the c-client install hangs on you, try changing this in the script and running it again: 

make ldb  > /dev/null 2>&1

to 

make -i ldb SSLTYPE=none

Note: Doing so will cause the output to be sent to you meaning that you will have to wait until this point in your script(about 50min) then come back and hit "y" then enter/return twice at the prompt. This is the only way I could get c-client to install properly.

Internal Server Error

If some of your php files return an internal server error (Server error 500) the install script probably copied the php binary when you needed the php-cgi binary. execute 
cp ~/php5/bin/php-cgi ~/DOMAINNAME/cgi-bin/php.cgi
and you will probably be fine.

"Bad interpreter" or "command not found" errors

If you create the file on Windows, then upload to the server, you can get the above errors when running the script.

It's easy to fix. 

     vi installscript

then, within vi enter 

     :set fileformat=unix
     :wq

Now it should run correctly.

Borrow an Already Compiled PHP

Instead of compiling your own PHP, you can copy Dreamhost's already working executable into your own directory, or use a wrapper to use DreamHost's PHP-CGI executable with your own php.ini file. From there, you can change the php.ini as you see fit. More information can be found about this in PHP.ini.

AddHandler vs. AddType

On our own servers, we use the AddType Apache directive: 

AddType application/x-httpd-php .php
Action application/x-httpd-php /cgi-bin/php.cgi

- however this did not work for us at DreamHost. Instead, we had to use the AddHandler Apache directive: 

AddHandler php-cgi .php
Action php-cgi /cgi-bin/php.cgi
