Study Notes

On the current AMD x64 platform, I install CentOS4.4 and related development packages. This article is How-To set up Apache + PHP in Linux box. It takes me about two hours in fixing this issue. So it seems in pretty good.

1. Download the latest Apache and PHP distributions
httpd-2.2.4.tar.bz2
php-4.4.6.tar.gz

2. Install Apache
Un-compress the install file:
# bunzip httpd-2.2.4.tar.bz2
# tar xvf httpd-2.2.4.tar
# cd httpd-2.2.4

For our Web GUI needs the httpd to be owned by supervisor “root”, the following environment parameter must be added before compiling and building.
# env CFLAGS=”-Wall -DBIG_SECURITY_HOLE” ./configure –prefix=/usr/local/apache –enable-so
–predix indicates the installing path. –enable-so means compiling in DSO mode.
If the configure scripts completes successfully, you can then proceed:
# make && make install
Apache show compile without any hitches.

3. Install PHP
Unpack the PHP distribution, change to the PHP directory and run the configure script, you need to pass certains options to the script.
# tar zxvf php-4.4.6.tar.gz
# cd php-4.4.6

Here’s a complete configure script with Apache-support options.
#./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache/bin/apxs
–with-apxs2 means it supports Apache2.0, this option must be appended.
# make && make install

After it has installed, we need to install the PHP.ini file:
# cp php.ini-optimized /usr/local/lib/php.ini
Note, the above copying step is not always required.

If the installation completes successfully, there will be a file named “libphp4.so” in /usr/local/apache/modules:
# ls /usr/local/apache/modules/
httpd.exp libphp4.so

4. Modify the /usr/local/apache/conf/httpd.conf to enable PHP options. Here’s an example from BA880:
# vi /usr/local/apache/conf/httpd.conf

I’ve marked the modified texts by blue font. Note, this special httpd’s owner is “root”.

5. Install Web GUI for BA880:
# mkdir -p /opt/work/httpd
# scp -rf 192.168.3.246:/os/httpd/* /opt/work/httpd
# mv /etc/export /etc/exports.bak
# mv /etc/samba/smb.conf /etc/samba/smb.conf.bak
# ln -s /opt/work/httpd/related/var/etc/exports /etc/exports
# ln -s /opt/work/httpd/related/var/etc/smb.conf /etc/samba/smb.conf

6. Start up Apache:
# /usr/local/apache/bin/apachectl -k start

7. Verify its working status:
# ps -x | grep httpd
6156 ? S 0:00 /usr/local/apache/bin/httpd -k start
6157 ? S 0:00 /usr/local/apache/bin/httpd -k start
6158 ? S 0:00 /usr/local/apache/bin/httpd -k start
6160 ? S 0:00 /usr/local/apache/bin/httpd -k start
If see the above lines, it measn everything runs well.
Open Web Browser, and input the IP address, it would be accessed by http.
