maybe a little off topic. This page is about Nginx, mysql, php and wordpress

http://www.mensk.com/webmaster-toolbox/ ... wordpress/

I post this page because I think it's a complete guide on an application (WordPress) setup, so it's very helpful for newcomers. And, one day, you may be interested in Nginx

please be noted, this page is written for SliceHost, but really it can be used on any Ubuntu server.

To add some extra confusion, in my signature there's a guide for Lighttpd instead of Apache and nginx, in combination with PHP/MySQL and mail via Google apps for domain (with msmtp)

Setup the ultimate Ubuntu/Lighttpd/PHP/MySQL server, and keep it running: http://nanotux.com/blog/the-ultimate-server/

Seemed appropriate to ask questions in this ongoing thread. I'm setting up a web server so I can ultimately transfer my site there. I used the perfect server guide found at the beginning of this thread on a clean install of Ubuntu 8.10. Before I jump to the end, some notes on the process:

(1) I began with step 8.

(2) AppArmor did not seem to be installed by default.

(3) Step 15 asks you to telnet to test an install. My results differed slightly:

250-AUTH PLAIN NTLM LOGIN DIGEST-MD5 CRAM-MD5

instead of

250-AUTH PLAIN LOGIN

(4) phpMyAdmin was not included in guide, but I installed it before step 22 (ISPConfig installation). At this point, the phpMyAdmin index page would show text (due to php being disabled globally I assume) and visiting the site would display "It works!" or some variation of.

(5) The installation of ISPConfig 3 seemed to duplicate a lot of the packages I had already installed following the guide. I left those out. I did not install suPHP.

(6) During the installation of ISPConfig I landed at this prompt:
Without finding any further instructions I quit and was greeted with:

This was not my intention. If there's further configuration to do I'm unsure how to go about it.

(7) I made the Apache fixes as instructed for ISPConfig, then uncommented the lines in /etc/mime.types for PHP, assuming this would let me run php files (such as phpmyadmin). However... things appear to be fubar'd. I get a nice 404 visiting the site now, and restarting Apache gives me this warning:



Is the installation salvageable, or do I start from scratch? Any help is appreciated.

You might want to install lighttpd instead of apache, depending on how much memory your linode account has, as it uses less RAM.

Steps
1. Firewall

# apt-get install arno-iptables-firewall

The installation will prompt you for the ports to enabled. Ports you may want to enable:

• 7 echo (for ping)
• 22 ssh
• 25 smtp
• 80 http
• 110 pop3
• 143 Imap
• 443 https
• 993 Imap over ssl/tls
• 995 pop3 over ssl/tls
• 3306 mysql

2. Create a script, say, ~/firewall-stop to flush all iptables rules (just in case you need it).

#!/bin/bash 
echo "Stopping firewall and allowing everyone..." 
iptables -F 
iptables -X 
iptables -t nat -F 
iptables -t nat -X 
iptables -t mangle -F 
iptables -t mangle -X 
iptables -P INPUT ACCEPT 
iptables -P FORWARD ACCEPT 
iptables -P OUTPUT ACCEPT 

# sudo chmod u+x ~/firewall-stop

You can execute it

# sudo ~/firewall-stop

if you get locked out, from the linode console java applet (without needing to ssh).
3. Install lighttpd

# aptitude install lighttpd 

4. Either create a file uploads directory for lighttpd or set upload_tmp_dir in php.ini and create the directory, setting the group to www-data (chgrp) and setting the permissions appropriately. This step is not needed as of lighttpd 1.4.19 and above.

# mkdir /var/cache/lighttpd/uploads 
# chgrp –R www-data /var/cache/lighttpd/uploads 
# chmod g+rw /var/cache/lighttpd/uploads 

5. Enable fastcig and auth modules

# lighty-enable-mod fastcgi auth 

6. Install php and phpmyadmin

# aptitude install php-cgi php5-cli php-db php-pear php5-gd php5-mcrypt php5-mysql php5-xcache phpmyadmin

7. Create the ‘recommended’ php.ini

# cp /usr/share/doc/php5-common/examples/php.ini-recommended /etc/php5/cgi/php.ini 

8. Configure fast-cgi

fastcgi.server = 
(
 ".php" =>  ((    "bin-path" => "/usr/bin/php-cgi -c /etc/php5/cgi/php.ini", 
   "socket" => "/tmp/php.socket", 
   "max-procs" => 1, 
   "idle-timeout" => 20, 
   "bin-environment" => ( "PHP_FCGI_CHILDREN" => "4", "PHP_FCGI_MAX_REQUESTS" => "10000" ), 
"bin-copy-environment" => ( "PATH", "SHELL", "USER" ), 
"broken-scriptfilename" => "enable"
 )) 
) 

See Lighttpd and PHP configuration for more information. max-procs = 1 is recommended is using an php op code cacher.

9. Install php op code cacher xcache.

# aptitude install  php5-xcache

Encrypt and set the password for the administration page for xcache. See How to Install XCache Administration Page. You need to encrypt your xcache admin password by creating and running this php script:

<?php
echo md5("password");
?>

substituting your actuall password for "password". Then edit /etc/php5/conf.d/xcache.ini and change the lines

xcache.admin.user = "mOo"
xcache.admin.pass = "5f4dcc3b5aa765d61d8327deb882cf99"

using a user name of your choice and the encrypted password generate from the script above.

10. Set up any virtual hosts for lighttpd (If you have many, then you would want to either enable simple_vhost or use the built-in evhost.path-pattern setting in /etc/lighttpd/lighttpd.conf).

Sampe virtual hosts

# sudo nano /etc/lighttpd/lighttpd.conf

$HTTP["host"] =~ "^(www\.)?sampledomain1.com$" {
 server.document-root = "/usr/share/phpgedview/"
}

$HTTP["host"] =~ "^(www\.)?someblog.com$" {
 server.document-root = "/usr/share/wordpress/"
}

$HTTP["host"] =~ "^(www\.)?sampledomain3.com$" {
   server.document-root = "/var/www/sampledomain3.com/"
}

# /etc/init.d/lighttpd force-reload. 

=~ signifies a regular expresssion syntax is being used.
Include any aliases in a separate file.

# sudo nano /etc/lighttpd/myconf.conf
alias.url += ( "/xcache-admin" => "/usr/share/xcache/admin",
"/aptitude" => "/usr/share/doc/aptitude/html/en",
"/apt-doc" => "/usr/share/doc/apt-doc")

Edit /etc/lighttpd/lighttpd.conf and add the line

include "myconf.conf"

after the virtual host entries.
11. Set up users and password for any password-protected lighttpd directories. See this guide: Lighttpd setup a password protected directory
12. restart lighttpd

# /etc/init.d/lighttpd restart 

Following up on my previous post: I blanked out my installation and started from scratch. I installed ISPConfig 2 and was able to login without problems. I updated the e-mail address to my own from the default root@localhost then logged out. I installed phpMyAdmin only to find out I could no longer connect to ISPConfig. I uncommented PHP in /etc/mime.types and in /etc/apache2/mods-enabled/php5.conf (as per the Perfect Server guide) which gets phpMyAdmin working, but still no luck with ISPConfig. Any ideas what I may have missed?
