Installation Instructions for PHP3 ---------------------------------- For the impatient here is a quick set of steps that will build PHP3 as an Apache module for Apache 1.3.0 with MySQL support. A more verbose explanation follows. QUICK INSTALL gunzip apache_1.3.x.tar.gz tar xvf apache_1.3.x.tar gunzip php-3.0.x.tar.gz tar xvf php-3.0.x.tar cd apache_1.3.x ./configure --prefix=/www cd ../php-3.0.x ./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars make make install cd ../apache_1.3.x ./configure --prefix=/www --activate-module=src/modules/php4/libphp4.a (The above line is correct! Yes, we know libphp4.a does not exist at this stage. It isn't supposed to. It will be created.) make (you should now have an httpd binary which you can copy to your Apache bin dir) cd ../php-3.0.x cp php3.ini-dist /usr/local/lib/php3.ini You can edit /usr/local/lib/php3.ini file to set PHP options. Edit your httpd.conf or srm.conf file and add: AddType application/x-httpd-php3 .php3 VERBOSE INSTALL Installing PHP3 can be done in four simple steps: 1. Unpack your distribution file. You will have downloaded a file named something like php3xn.tar.gz. Unzip this file with a command like: gunzip php3xn.tar.gz Next you have to untar it with: tar -xvf php3xn.tar This will create a php-3.0.x directory. cd into this new directory. 2. Configure PHP3. You now have to choose the options you would like. There are quite a few of them. To see a list, type: ./configure --help You can also use the supplied 'setup' script, which will ask you a series of questions and automatically run the configure script for you. The only options that you are likely to want to use are the ones in the last section entitled, "--enable and --with options recognized:" A popular choice is to build the Apache module version. You need to know where the source code directory for your Apache server is located. Then use an option like: --with-apache=/usr/local/src/apache if that is your Apache source code directory. If you only specify --with-apache, then it will default to look for your Apache source in /usr/local/etc/httpd. NOTE: The directory you specify should be the top-level of the unpacked Apache (or Stronghold) distribution. The configure program will automatically look for httpd.h in different directories under that location depending on which version of Apache, including Stronghold, you are running. For MySQL support, since newer versions of MySQL installs its various components under /usr/local, this is the default. If you have changed the location you can specify it with: --with-mysql=/opt/local for example. Otherwise just use: --with-mysql *NOTE* If you are using Apache 1.3b6 or later, you should run the Apache Configure script at least once before compiling PHP. It doesn't matter how you have Apache configured at this point. 3. Compile and install the files. Simply type: make install For the Apache module version this will copy the appropriate files to the src/modules/php4 directory in your Apache distribution if you are using Apache 1.3.x. If you are still running Apache 1.2.x these files will be copied directly to the main src directory. For Apache 1.3b6 and later, you can use the new APACI configuration mechanism. To automatically build Apache with PHP support, use: cd apache_1.3.x ./configure --prefix=//apache \ --activate-module=src/modules/php4/libphp4.a make make install If you do not wish to use this new configuration tool, the old install procedure (src/Configure) will work fine. If you are using the old Apache ./Configure script, you will have to edit the Apache src/Configuration file manually. If you do not have this file, copy Configuration.tmpl to Configuration. For Apache 1.3.x add: AddModule modules/php4/libphp4.a For Apache 1.3.x don't do anything else. Just add this line and then run "./Configure" followed by "make". For Apache 1.2.x add: Module php3_module mod_php4.o For Apache 1.2.x you will also have to look in the libphp4.module file, which was copied to the src directory. The EXTRA_LIBS line in the Apache Configuration file needs to be set to use the same libs as specified on the LIBS line in libphp4.module. You also need to make sure to add "-L." to the beginning of the EXTRA_LIBS line. So, as an example, your EXTRA_LIBS line might look like: EXTRA_LIBS=-L. -lphp3 -lgdbm -ldb -L/usr/local/mysql/lib -lmysqlclient NOTE: You should not enclose the EXTRA_LIBS line in double-quotes, as it is in the libphp4.module file. Also, look at the RULE_WANTHSREGEX setting in the libphp4.module file and set the WANTHSREGEX directive accordingly in your Configuration file. This last step applies to versions of Apache prior to 1.3b3. This is a bit of a hassle, but should serve as incentive to move to Apache 1.3.x where this step has been eliminated. Once you are satisfied with your Configuration settings, type: ./Configure If you get errors, chances are that you forgot a library or made a typo somewhere. Re-edit Configuration and try again. If it goes well, type: make 4. Setting up the server. You should now have a new httpd binary. Shut down your existing server, if you have one, and copy this new binary overtop of it. Perhaps make a backup of your previous one first. Then edit your conf/srm.conf file and add the line: AddType application/x-httpd-php3 .php3 There is also an interesting feature which can be quite instructive and helpful while debugging. That is the option of having colour syntax highlighting. To enable this, add the following line: AddType application/x-httpd-php3-source .phps Any file ending in .phps will now be displayed with full colour syntax highlighting instead of being executed. When you are finished making changes to your srm.conf file, you can start up your server.
