Apache w/ PHP and MySQL Support (PowerPC)

''Originally by Nick and edited by ... BurnHard, frontalot, Cathedrow & Ralf from linkstationwiki.org'' '''Installing Apache w/ PHP and MySQL Support. '''

Opening Comments
LAMP (or L.A.M.P.) refers to a set of free software programs commonly used together to run dynamic Web sites or servers:
 * Linux, the operating system;
 * Apache, the Web server;
 * MySQL, the database management system (or database server);
 * PHP scripting/programming language.

Apache, along with PHP and MySQL, is very straight forward to install on a stock LinkStation 1 with the OpenLink firmware installed. If you have experience with building these packages, or compiling in general, it is a snap. If you have little or no experience in such matter, just follow the guide -- everything is reversible.

If you have not already done so, visit the Openlink section and follow the instructions for installing the telnet enabled firmware. You will also need to download and install the PPC Tools before continuing.

A Remark on "--prefix"
The prefix argument, which you will see in every section below, allows you to install Unix packages to alternate locations. This is very important is the case of the LinkStation since all three packages take over 75 megs to install. You will not be able to install these packages to your root partition and doing so would be very bad.

I chose to create an "opt" directory under "/mnt/" to install each of these packages too, using a separate directory for each. This was done to keep the packages separated and easy to manage in the future. You may, of course, alter your install locations in any way but, if you are new to this, I suggest following my example.

It's also a good idea to create a directory to download stuff when using wget, lets use /mnt/misc

MySQL
Begin with MySQL. If you do not wish to compile MySQL support into your system, please skip to the next section.

cd /mnt/misc wget http://www.mirrorservice.org/sites/ftp.mysql.com/Downloads/MySQL-4.1/mysql-4.1.20.tar.gz tar -zxvf mysql-4.1.20.tar.gz cd mysql-4.1.20
 * Download the latest recommended release of MySQL from http://www.mysql.com (4.1.20, at the time of this edit).

groupadd mysql

(Not sure if this is necessary, just following instructions from dev.mysql.com)


 * [Ralf] without this MySQL will try to run as root, but you need several special settings for this - better stick to the extra mysql user

useradd -g mysql mysql

./configure --prefix=/mnt/opt/mysql --with-readline make make install

cp support-files/my-small.cnf /etc/my.cnf


 * [Ralf] there are more sample configuration files which you can try, e.g. my-small.cnf. Read the beginning of the files for a description

cd /mnt/opt/mysql bin/mysql_install_db --user=mysql

This creates databases

chown -R root. chown -R mysql var chgrp -R mysql.

[Ralf] MySQL 5 seems to require the following extra actions:

libexec/mysqlmanager --passwd --user mysql >> /etc/mysqlmanager.passwd mysql
 * Create a MySQL password file:
 * At the following prompt enter

You should now have a fully functioning version of MySQL on your LinkStation. Now we can set up the server to start like any other service.

Go back to where you have build MySQL

/mnt/misc/mysql-4.1.20 cp support-files/mysql.server /etc/init.d chmod 755 /etc/init.d/mysql.server

You can now start your MySQL daemon as follows:

/etc/init.d/mysql.server start

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands:

/mnt/opt/mysql/bin/mysqladmin -u root password ' new-password ' /mnt/opt/mysql/bin/mysqladmin -u root -h ' servername ' password ' new-password '

Start up and shutdown at boot

ln -s /etc/init.d/mysql.server /etc/rc.d/rc2.d/S99mysql.server ln -s /etc/init.d/mysql.server /etc/rc.d/rc6.d/K92mysql.server ln -s /etc/init.d/mysql.server /etc/rc.d/rc0.d/K92mysql.server

Important Memory Usage Note :

MySQL takes just under 25% of the LinkStation's total available memory when running. This should be taken into serious consideration if you choose to install MySQL support with your web server.


 *  TODO: Need to get the server running automatically at boot.

[Ralf] Here is how to start MySQL 5 automatically at boot. I guess it works quite similar with MySQL 4.X.

cd /etc/rc.d ln -s ../init.d/mysql.server rc2.d/S99mysql ln -s ../init.d/mysql.server rc2.d/K99mysql

Apache 1.3.xx
Apache itself is the next install. If you are not planning on installing PHP, you may ignore the "--enable-module=so" attribute below.

I decided to install Apache 1.3 because that is what my web host uses. Installing Apache 2 would be very similar and the following instructions can be easily adapted by reading the INSTALL document in the Apache 2 tarball.

cd /mnt/misc

Download the latest version of Apache 1.3 from http://www.apache.org (1.3.36, at the time of this edit).

wget http://apache.rmplc.co.uk/httpd/apache_1.3.36.tar.gz tar -zxvf apache_1.3.36.tar.gz cd apache_1.3.36

./configure --prefix=/mnt/opt/apache --enable-module=so make make install

You should get this message -

++ | You now have successfully built and installed the     | | Apache 1.3 HTTP server. To verify that Apache actually | | works correctly you now should first check the        | | (initially created or preserved) configuration files  | |                                                       | |   /mnt/opt/apache/conf/httpd.conf |                                                       | | and then you should be able to immediately fire up     | | Apache the first time by running:                     | |                                                       | |   /mnt/opt/apache/bin/apachectl start |                                                       | | Thanks for using Apache. The Apache Group       | |                            http://www.apache.org/     | ++

You will, at the very least, need to change your port to 81 (or some other port).

vi /mnt/opt/apache/conf/httpd.conf

Search for '80' -- change it to '81' (or some other port).

I also suggest changing the root directory to the files to "/mnt/hda/share/www" so you can have easy access to them over the Samba share. Search for 'DocumentRoot' and change the first reference (roughly line 288) to the above path. Search again and you will find another reference to change (around line 313).

Finally, start the server.

/mnt/opt/apache/bin/apachectl start

Copy that start up script to /etc/init.d and include in startup shutdown

cp /mnt/opt/apache/bin/apachectl /etc/init.d

ln -s /etc/init.d/apachectl /etc/rc.d/rc2.d/S99apachectl ln -s /etc/init.d/apachectl /etc/rc.d/rc6.d/K92apachectl ln -s /etc/init.d/apachectl /etc/rc.d/rc0.d/K92apachectl


 *  TODO: Flush out the config file editing instructions.

PHP
Last we will set up PHP. I decided to install the latest version of PHP4 because, again, this is what my web host uses. You may decide to install PHP5, which would requires only 1 slightly different step below.

IMPORTANT

Pay special attention to the 'configure' command below. If you installed the above packages to an alternate location you will need to update the paths in the proper attribute.

cd /mnt/misc

Download the latest version of PHP4 from http://www.php.net (4.4.2, at the time of this edit).

wget http://uk2.php.net/get/php-4.4.2.tar.bz2/from/uk.php.net/mirror

or you can download the 4.4.3 version here

wget http://uk2.php.net/get/php-4.4.3.tar.bz2/from/uk.php.net/mirror

It may download as a file called 'mirror' if so mv mirror php-4.4.2.tar.bz2

bunzip2 php-4.4.2.tar.bz2 tar -xvf php-4.4.2.tar cd php-4.4.2

This is all one command and should be input on one line ./configure --prefix=/mnt/opt/php4 --with-mysql=/mnt/opt/mysql --with-apxs=/mnt/opt/apache/bin/apxs --with-config-file-path=/mnt/opt/php4/lib

If you're wanting swisscenter you need to

./configure --prefix=/mnt/opt/php4 --with-apxs=/mnt/opt/apache/bin/apxs --with-mysql=/mnt/opt/mysql --with-zlib --with-zlib-dir --with-gd --enable-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-config-file-path=/etc --enable-mbstring

Should get this ++ | License:                                                          | | This software is subject to the PHP License, available in this    | | distribution in the file LICENSE.

make

You will get a message

Build complete. (It is safe to ignore warnings about tempnam and tmpnam).

Then to finish

make install

Copy over the default config file.

IMPORTANT

If you altered the "--with-config-file-path" attribute, above, you will need to change the below command to copy to the appropriate path.

cp php.ini-dist /mnt/opt/php4/lib

Open up apache's conf file and verify that the following line is included:

vi /mnt/opt/apache/conf/httpd.conf

LoadModule php4_module libexec/libphp4.so (for PHP4) LoadModule php4_module libexec/libphp5.so (for PHP5)

If it is not, add it. Also add the following two lines just below the LoadModule command:

AddType application/x-httpd-php .php .phtml AddType application/x-httpd-php-source .phps

Restart Apache and PHP should now be working.

/etc/init.d/apachectl restart
