Configuring the IPv6 with this blog :)

So, after reading several websites which now IPv6 enable, I would like to make this blog IPv6 enable too… :p
First case is, I can run this blog under IPv6 with BuyVM without problem. Buy with another host, I always have a problem. But thank’s to the LET, when I post a thread about this issues, Mr. Salvatore from Prometeus/Iperweb comes with a suggestion.
When I’m running this blog with Ubuntu 10.04, I can run without problem with BuyVM, but with another host, with the same Ubuntu 10.04, and the same configuration for PHP and Lighttpd, I always facing issues. So I decided to try another OS, Ubuntu 11.10 32 bit with VPS from Prometeus/Iperweb.
By using Ubuntu 11.10, we get Lightpd 1.4.28.
And the configuration is a bit different from Ubuntu 10.04 / Lighttpd 1.4.26.
So, here is the steps I take to make this blog running under Ubuntu 11.10 :

Create a backup of WordPress directory and database at another VPS
Fresh Installation of Ubuntu 11.10 VPS

Update / Upgrade, and removing unneeded packages :

# apt-get -y update && apt-get -y upgrade && service apache2 stop && apt-get -y remove apache2 && apt-get -y remove portmap && apt-get -y remove bind9 && apt-get -y remove samba && rm -rf /usr/sbin/apache2

1	# apt-get -y update && apt-get -y upgrade && service apache2 stop && apt-get -y remove apache2 && apt-get -y remove portmap && apt-get -y remove bind9 && apt-get -y remove samba && rm -rf /usr/sbin/apache2

Installing needed component to run as a Webserver:

# apt-get install -y nano squid openvpn gcc c++ g++ lighttpd mysql-server php5-cgi php5-mysql php5-gd php5-curl php5-imagick php5-memcache php5-xcache zip

1

# apt-get install -y nano squid openvpn gcc c++ g++ lighttpd mysql-server php5-cgi php5-mysql php5-gd php5-curl php5-imagick php5-memcache php5-xcache zip
Download the backup file and databases :

# wget www.backupserver.com/backup.sql && wget www.backupserver.com/backup.tar.gz

1

# wget www.backupserver.com/backup.sql && wget www.backupserver.com/backup.tar.gz
Copying the files to the webdir and extract it :

cp /root/backup.tar.gz /var/www && cd /var/www && tar xf backup.tar.gz

1

cp /root/backup.tar.gz /var/www && cd /var/www && tar xf backup.tar.gz

Creating Databases and Import the backup database to the system :

# mysql -u root -p
 Insert the MySQL password for root...
mysql&gt; create database database_name;
mysql&gt; grant usage on *.* to database_user@localhost identified by 'database_password';
mysql&gt; grant all privileges on database_name.* to database_user@localhost;
mysql&gt; flush privileges;
mysql&gt; exit;
# mysql -u database_user --password=database_password database_name &lt; /root/backup.sql

# mysql -u root -p

Insert the MySQL password for root...

mysql> create database database_name;

mysql> grant usage on *.* to database_user@localhost identified by 'database_password';

mysql> grant all privileges on database_name.* to database_user@localhost;

mysql> flush privileges;

mysql> exit;

# mysql -u database_user --password=database_password database_name < /root/backup.sql

Configure the Lighttpd 1.4.28 to work with IPv6 :

# nano /etc/lighttpd/lightpd.conf
server.modules = (
	"mod_access",
	"mod_alias",
	"mod_compress",
 	"mod_redirect",
      "mod_rewrite"
)
server.document-root        = "/var/www"
server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www-data"
server.groupname            = "www-data"
index-file.names            = ( "index.php", "index.html",
                                "index.htm", "default.htm",
                               "index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
## Use ipv6 if available
#server.bind = "[::]"
include_shell "/usr/share/lighttpd/use-ipv6.pl"
dir-listing.encoding        = "utf-8"
server.dir-listing          = "enable"
compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

# nano /etc/lighttpd/lightpd.conf

server.modules = (

"mod_access",

"mod_alias",

"mod_compress",

"mod_redirect",

"mod_rewrite"

)

server.document-root = "/var/www"

server.upload-dirs = ( "/var/cache/lighttpd/uploads" )

server.errorlog = "/var/log/lighttpd/error.log"

server.pid-file = "/var/run/lighttpd.pid"

server.username = "www-data"

server.groupname = "www-data"

index-file.names = ( "index.php", "index.html",

"index.htm", "default.htm",

"index.lighttpd.html" )

url.access-deny = ( "~", ".inc" )

static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )

## Use ipv6 if available

#server.bind = "[::]"

include_shell "/usr/share/lighttpd/use-ipv6.pl"

dir-listing.encoding = "utf-8"

server.dir-listing = "enable"

compress.cache-dir = "/var/cache/lighttpd/compress/"

compress.filetype = ( "application/x-javascript", "text/css", "text/html", "text/plain" )

include_shell "/usr/share/lighttpd/create-mime.assign.pl"

include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

Configuring the simple-vhost :

# nano /etc/lighttpd/conf-enabled/10-simple-vhost
# /usr/share/doc/lighttpd-doc/simple-vhost.txt
server.modules += ( "mod_simple_vhost" )
## The document root of a virtual host is document-root =
##   simple-vhost.server-root + $HTTP["host"] + simple-vhost.document-root
simple-vhost.server-root         = "/var/www"
simple-vhost.document-root       = "html"
## the default host if no host is sent
simple-vhost.default-host        = "www.example.com"

# nano /etc/lighttpd/conf-enabled/10-simple-vhost

# /usr/share/doc/lighttpd-doc/simple-vhost.txt

server.modules += ( "mod_simple_vhost" )

## The document root of a virtual host is document-root =

## simple-vhost.server-root + $HTTP["host"] + simple-vhost.document-root

simple-vhost.server-root = "/var/www"

simple-vhost.document-root = "html"

## the default host if no host is sent

simple-vhost.default-host = "www.example.com"

Enabling fastcgi and fastcgi-php in Lighttpd:

# lighttpd-enable-mod fastcgi
# /etc/init.d/lighttpd force-reload
# lighttpd-enable-mod fastcgi-php
# /etc/init.d/lighttpd force-reload

# lighttpd-enable-mod fastcgi

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

# lighttpd-enable-mod fastcgi-php

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

Do remember that php-cgi is running 4 child by default, so it might eat some memory. You can tweak it by changing it :

# nano nano /etc/lighttpd/conf-enabled/15-fastcgi-php

1	# nano nano /etc/lighttpd/conf-enabled/15-fastcgi-php

# /usr/share/doc/lighttpd-doc/fastcgi.txt.gz
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ConfigurationOptions#mod_fastcgi-fastcgi
## Start an FastCGI server for php (needs the php5-cgi package)
fastcgi.server += ( ".php" =&gt;
	((
		"bin-path" =&gt; "/usr/bin/php-cgi",
		"socket" =&gt; "/tmp/php.socket",
		"max-procs" =&gt; 1,
		"bin-environment" =&gt; (
			"PHP_FCGI_CHILDREN" =&gt; "1",
			"PHP_FCGI_MAX_REQUESTS" =&gt; "1000"
		),
		"bin-copy-environment" =&gt; (
			"PATH", "SHELL", "USER"
		),
		"broken-scriptfilename" =&gt; "enable"
	))
)

# /usr/share/doc/lighttpd-doc/fastcgi.txt.gz

# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ConfigurationOptions#mod_fastcgi-fastcgi

## Start an FastCGI server for php (needs the php5-cgi package)

fastcgi.server += ( ".php" =>

((

"bin-path" => "/usr/bin/php-cgi",

"socket" => "/tmp/php.socket",

"max-procs" => 1,

"bin-environment" => (

"PHP_FCGI_CHILDREN" => "1",

"PHP_FCGI_MAX_REQUESTS" => "1000"

"bin-copy-environment" => (

"PATH", "SHELL", "USER"

"broken-scriptfilename" => "enable"

))

)

Restart the Lighttpd :

# service lighttpd restart

1

# service lighttpd restart
