!! Note this is NOT required on Ubuntu 14.04 because these modules are enabled by default !!
 
 
 
 
 
 
 
==Firewall==
 
 
 
You have to open the following ports:
 
* Port 80 = HTTP
 
* Port 443 = HTTPS
 
 
 
<syntaxhighlight lang="bash">
 
$IPTABLES -A INPUT -p tcp -m state -i eth0 --dport 80 -j ACCEPT

</syntaxhighlight>
 
 
 
Restart the firewall
 
 
 
<syntaxhighlight lang="bash">
 
/etc/init.d/firewall restart
 
</syntaxhighlight>
 
 
 
 
 
  
==Test your installation==
+

* Let CGI behaves like before: set <code>cgi.fix_pathinfo=1</code>
 +
* Adjust file upload size <code>upload_max_filesize = 32M</code>
 +
* Adjust post size <code>post_max_size = 32M</code>
 +
* Adjust time zone <code>date.timezone = Europe/Paris</code>
 +
* Save path: <code>session.save_path = "/tmp"</code>
  
 +
===Check PHP version and configuration===
  
You can now test your installation by going to 'http://localhost' or 'http://myServer'. You should see the default page.

==Enable / disable virtual host(s)==
 
 
 
 
 
'''Virtual Host desactivation'''
 
 
 
If you're listening on '''*:80''' then you should probably disable the default virtual host before enabling yours!
 
 
 
<syntaxhighlight lang="bash">
 
a2dissite 000-default
 
</syntaxhighlight>
 
 
 
 
 
 
 
 
 
'''Virtual Host activation'''
 
 
 
To activate a Virtual Host, just type
 
 
 
<syntaxhighlight lang="bash">
 
a2ensite  myServer
 
</syntaxhighlight>
 
 
 
Then, restart your web server
 
 
 
<syntaxhighlight lang="bash">
 
/etc/init.d/apache2 restart
 
</syntaxhighlight>
 
 
 
 
 
Check your server! You should see your "index.html" page.
 
 
 
 
 
 
 
=Apache 2 configuration # SSL Virtual host=
 
 
 
 
 
==Create SSL certificate==
 
 
 
First of all, you need to create a server certificate.
 
Cf. SSL dedicated document → Create a new server certificate
 
 
 
>> see [[SSL server]]
 
 
 
 
 
 
 
==Enable SSL module==
 
 
 
You have to either copy or create symlinks for server certificate.
 
 
 
To avoid rights collision I'm using a ''copy'' operation. However I know from past experience that ''symLinks'' work very well if you set the correct rights.
 
 
 
 
 
-Note-
 
 
 
You MUST use the NON-ENCRYPTED private key if you want to start Apache2 automatically on each reboot.
 
 
 
 
 
 
 
'''Copy certificates'''
 
 
 
<syntaxhighlight lang="bash">
 
cp /srv/ssl/certs/myServer.cert.pem /etc/apache2/webServer.pem
 
cp /srv/ssl/private/myServer.nopass.key /etc/apache2/webServer.key
 
</syntaxhighlight>
 
 
 
 
 
 
 
Alternative: '''Symlinks to /srv/ssl/'''
 
 
 
<syntaxhighlight lang="bash">
 
ln -s /srv/ssl/certs/myServer.cert.pem /etc/apache2/webServer.pem
 
ln -s /srv/ssl/private/myServer.nopass.key /etc/apache2/webServer.key
 
</syntaxhighlight>
 
 
 
 
 
 
 
'''Activate the SSL module'''
 
 
 
<syntaxhighlight lang="bash">
 
a2enmod ssl
 
</syntaxhighlight>
 
 
 
 
 
 
 
==Prepare virtual host (optional)==
 
 
 
Create virtual host folder
 
 
 
<syntaxhighlight lang="bash">
 
mkdir -p /var/www/myServer-ssl
 
cp /var/www/index.html /var/www/myServer-ssl
 
chown -R www-data:www-data /var/www/myServer-ssl
 
</syntaxhighlight>
 
 
 
 
 
 
 
==Prepare the log files (optional)==
 
 
 
<syntaxhighlight lang="bash">
 
# That should already exists from before
 
mkdir -p /var/log/apache2/myServer
 
 
 
# Create *-ssl.log
 
touch /var/log/apache2/myServer/error-ssl.log
 
touch /var/log/apache2/myServer/access-ssl.log
 
chmod -R 660 /var/log/apache2/myServer/*
 
chown -R www-data:www-data /var/log/apache2/myServer/*
 
</syntaxhighlight>
 
 
 
 
 
 
 
Create a default "/var/www/myServer-ssl/index.html" to check your virtual host.
 
 
 
If you'd like you can use this ultra-simple file [http://daxiongmao.eu/wiki_upload_files/apache2/index.html]
 
 
 
<syntaxhighlight lang="bash">
 
cd /var/www/myServer-ssl/
 
wget http://daxiongmao.eu/wiki_upload_files/apache2/index.html
 
chown www-data:www-data index.html
 
</syntaxhighlight>
 
 
 
 
 
 
 
 
 
==Virtual host declaration==
 
 
 
You have 2 possibilities:
 
* Update your current virtual host (recommended)
 
* Create a new one, only for the SSL virtual host
 
 
 
 
 
'''Update non-ssl V.Host configuration'''
 
 
 
<syntaxhighlight lang="bash">
 
vim /etc/apache2/sites-available/myServer

!! Adjust the settings to your own configuration !!

Restart the web server
 
 
 
<syntaxhighlight lang="bash">
 
service apache2 restart
 
</syntaxhighlight>
 
 
 
 
 
Now you can test your server ''https://myServer''
 
 
 
 
 
If you've use a self-signed certificate you might see some alert. Just discarded it and process anyway!
 
 
 
 
 
 
 
 
 
 
 
 
 
=Apache 2 configuration # Redirections=
 
 
 
 
 
==Principle==
 
 
 
Just a little reminder...
 
 
 
[[File:Apache2_mod_rewrite.png|none|Apache2 mod_rewrite principle]]
 
 
 
 
 
* Redirections are '''not transparent'''
 
* Redirections are '''performed by the client'''. The server only serves the new URL to use
 
* Redirections can also be used as a security tool to filter HTTP requests and only allow some of them.
 
 
 
 
 
 
 
 
 
==Enable redirections==
 
 
 
Module "rewrite" allows you to redirect source URL to another one.
 
 
 
<syntaxhighlight lang="bash">
 
a2enmod rewrite
 
</syntaxhighlight>
 
 
 
 
 
 
 
==Redirect HTTP to HTTPS==
 
 
 
The safer way to redirect HTTP to HTTPS is use to adjust the virtual host configuration.
 
 
 
<syntaxhighlight lang="bash">
 
<VirtualHost *:80>
 
ServerAdmin guillaume@qin-diaz.com

=Apache 2 # redirections using mod_proxy=
 
 
 
 
 
Thanks to Julien Rialland for his insight regarding this part!
 
 
 
 
 
==Principle==
 
 
 
The proxy module allow you to redirect remote user to a specific server that can be host on a different machine or port through a clear URL.
 
 
 
 
 
===Current limits===
 
 
 
Some application are not available from outside…
 
 
 
* For security reasons [default URL is not allowed]
 
 
 
[[File:Apache2 proxy security limit.png|none|Proxy for security]]
 
 
 
 
 
* Due to network issues
 
 
 
[[File:Apache2 proxy network issues.png|none|Proxy to improve network]]
 
 
 
 
 
===Proxy module role===
 
 
 
The proxy module allow you to provide access through transparent redirection.
 
 
 
It relies on:
 
* Already open port (80 or 443)
 
* Redirection rule
 
* Each service URL must be unique
 
* The target service must be reachable by the web server
 
 
 
[[File:Apache2 proxy role.png|none|Proxy role]]
 
 
 
 
 
As you can see on the following example, the previous services will be accessible using some dedicated URL.
 
Remote “http://myServer/myService” will redirect to “http://localhost:8081”
 
 
 
→ The ''mod_proxy'' is none intrusive.
 
You don’t have to change anything is the orginal service configuration. Apache2 will handle all the transformations.
 
 
 
 
 
==Proxy / redirect / rewrite==
 
 
 
When Apache2 receive a request it will be process in the following order:
 
 
 
[[File:Apache2 proxy rewrite.png|none|Proxy rewrite]]
 
 
 
 
 
So, even if you enable a full redirection to HTTPS you can still use some HTTP service through mod_proxy.
 
 
 
 
 
==Enable proxy module==
 
 
 
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
a2enmod proxy proxy_http proxy_ajp
+
vim /var/www/html/phpinfo.php
 
</syntaxhighlight>
 
</syntaxhighlight>
 
 
==Configure proxy redirections==
 
 
You can configure the redirections in 2 ways:
 
* Through your virtual host configuration
 
* Through the module configuration file
 
 
 
===Module configuration file===
 
 
You have to edit / create the configuration file.
 
 
<syntaxhighlight lang="bash">
 
vim /etc/apache2/mods-enabled/proxy.conf
 
</syntaxhighlight>
 
 
 
===Virtual host===
 
 
Just edit again your previous V.Host:
 
 
<syntaxhighlight lang="bash">
 
vim /etc/apache2/sites-available/myServer.conf
 
</syntaxhighlight>
 
 
 
===Proxy declaration===
 
 
Adjust the file to:
 
 
<syntaxhighlight lang="bash">
 
<VirtualHost *:80>
 
...
 
## Proxy
 
ProxyVia On
 
        ProxyPreserveHost On
 
        <Proxy *>
 
            AddDefaultCharset off
 
            Order deny,allow
 
            Allow from all
 
</Proxy>
 
 
        #### To allow some URLs to go through without being proxy ####
 
# Active MQ REST web-service, required for hawt.io management
 
ProxyPass /activemq-api http://localhost:8161/activemq-api

line 675 → post_max_size=256K
 
line 814 → allow_url_fopen=Off
 
 
 
DO NOT enable the open_basedir (even if the test say so! It’s a troublesome setting)
 
 
 
Restart your server to load the changes:
 
<syntaxhighlight lang="bash">
 
service apache2 restart
 
</syntaxhighlight>
 
 
 
Re-run the test. Then:
 
* Ignore the open_basedir and upload_tmp_dir alerts, if any.
 
* You can enable some specific options with a .htaccess file
 
 
 
 
 
===Change Apache 2 UID===
 
Do not change the UID if you already have install web programs such as phpldapadmin or phpmyadmin, cacti, ...

Requirements

Before going through this tutorial, I recommend you to setup:



Installation

Apache 2

This will install web server + PHP + Perl + all required libraries.

Apache2 core

apt install apache2 apache2-utils 
apt install ssl-cert

Since Ubuntu 16.04 apache2-mpm-prefork is not required

Doc

apt install apache2-doc


Perl

apt-get install libapache2-mod-perl2 libapache2-mod-perl2-doc


SNMP

Sometimes you might encounter some SNMP errors on latest Debian based distributions.

In that case you have to install a new package and run it.

apt-get install snmp-mibs-downloader
download-mibs

PHP 8

2021-11: PHP 8 is not included in Ubuntu 20.04 LTS.

Source article: http://www.daxiongmao.eu/wiki/index.php?title=Apache_2&action=edit

Add PHP 8.0 repository

apt install software-properties-common
add-apt-repository ppa:ondrej/php
apt update

Install core packages

To install the latest version of PHP:

# PHP core
apt-get install php
apt-get install php-cli
# Apache2 support
apt install libapache2-mod-php


Modules PHP

apt-get install php-cgi 
#apt-get install php-opcache
apt-get install php-gd 
apt-get install php-bz2 
apt-get install php-curl 
apt-get install php-xmlrpc
apt-get install php-json 
apt-get install php-mysql 
apt-get install php-imap 
apt-get install php-mbstring
# Performances
apt install php-fpm libapache2-mod-fcgid

Enable modules

sudo a2enmod proxy_fcgi setenvif
sudo a2enconf php8.0-fpm

Utility

apt install php-pear

Configuration

Edit PHP config file:

vim /etc/php/8.0/cli/php.ini
  • Let CGI behaves like before: set cgi.fix_pathinfo=1
  • Adjust file upload size upload_max_filesize = 32M
  • Adjust post size post_max_size = 32M
  • Adjust time zone date.timezone = Europe/Paris
  • Save path: session.save_path = "/tmp"

Check PHP version and configuration

To ensure PHP 8.0 is well-installed just type:

php -v


Image Magick

apt install php-gd php-imagick imagemagick

Configuration

Edit PHP config file:

vim /etc/php/8.0/apache2/php.ini

Add / uncomment the following lines in Dynamic extensions area

// PHP 8  (~ line 904)
extension=bz2
extension=curl
extension=gd
extension=imap
extension=mysqli


!! Note this is NOT required on Ubuntu 20.04 because these modules are enabled by default !!

Firewall

see Firewall INPUT filters#Web server

Restart the firewall

/etc/init.d/firewall restart


Test your installation

Restart the Apache2 server

service apache2 restart


Create a simple PHP script

vim /var/www/html/phpinfo.php

Put the following:

<?php
phpinfo();
?>

Adjust rights

chown www-data:www-data /var/www/html/phpinfo.php
chmod 755 /var/www/html/phpinfo.php


You can now test your installation by going to 'http://localhost/phpinfo.php' or 'http://myServer/phpinfo.php'. You should see the default page.
