This section tells you how to do a fresh install of Apache on your
system. This will ensure that the PHP DSO will actually work when it's
dumped in there. The necessary preparations include enabling mod_so in
Apache, which allows Apache to use DSOs.
If you already have a version of Apache installed, you can check to see
if you have mod_so enabled. If you do, you can skip through this
section. To check for mod_so, do the following:
- cd to the Apache bin directory (/usr/local/apache_[version]/bin/ or
wherever you installed Apache originally)
- Type ./httpd -l
You should see a list of enabled modules, and if "mod_so.c" shows up in
that list, you can skip ahead to the PHP installation section. If
"mod_so.c" doesn't show up in your list, you can skip ahead to step 6 in
the list below, to enable mod_so in Apache.
But if mod_so isn't enabled, then it's time to install Apache from
scratch, which is easy -- just follow these simple steps:
- Go to http://www.apache.org/dist/ and grab the
latest version of the
source code.
- Put this file somewhere logical, like /usr/local/ or /opt/ or anywhere
else you want.
- Unzip or uncompress the file, so that you're left with the *.tar file.
- Type the following to un-tar the file into a directory called
apache_[version]:
tar -xvf apache_[version].tar
- cd into /usr/local/apache_[version] (or wherever you un-tared it)
- Type the following to prepare for building, replacing [path] with your
own path, such as /usr/local/apache[version] (no trailing slash!)
./configure --prefix=[path] --enable-module=so
At this point in the sequence the configuration script will check for a
few things, then build the makefiles. When the configuration process is
complete, your shell prompt will return. Hopefully, you had no fatal
errors or other bad warnings. If you encounter warnings or errors, try to
decipher the problem from the messages that appear and try the
configuration again. You can also visit Apache.org and read through their FAQs
and documentation.
If you had no errors, you're ready to move on to the build process. Just
type the following at the prompt:
make
The makefile runs through its paces, compiling Apache. Again, the goal
is to get through this step without warnings and fatal errors. When you're
back at the prompt, type:
make install
At this point, the compilation will create the final set of directories
and files and return a lovely message from the Apache Group, thanking you
for installing Apache on your system.
During the installation process, a default set of configuration files
was placed in the "conf" directory, under the installation directory (i.e.,
"/usr/local/apache_[version]/conf/" or some such). If you make a few minor
changes to the httpd.conf file (the master Apache configuration file), you
can start Apache and make sure that it's working properly.
- In your text editor of choice, open httpd.conf and find a line starting
with ServerAdmin.
- Change the default entry to real values, such as:
ServerAdmin joe@schmo.com
- Find a line starting with ServerName.
- Change the default entry to real values, such as:
ServerName localhost
If you have a real machine name, like mybox.yourdomain.com, go ahead and
use it instead of localhost:
ServerName mybox.yourdomain.com
- Save the file.
- cd up a directory (type cd ..)
- Start Apache using the following command:
./bin/apachectl start
This command will start Apache (hopefully). You should see a message
like "httpd started." Follow that up by opening your Web browser and type
"http://localhost/" in the location bar (if you used a ServerName other
than localhost, type that in the location bar instead). Again -- and I
can't stress this enough -- if your installation fails at any point, visit
the Apache website and read the FAQ and
documentation.
If everything is hunky-dory, move on to the next section to compile
PHP.
