== What is nginx ==
 +
 +
nginx (pronounced "engin-x") is a Web and reverse proxy server for HTTP, SMTP, POP3 and IMAP protocols. It focuses on high concurrency, performance and low memory usage. Nginx quickly delivers static content with efficient use of system resources, also dynamic content is delivered on a network using FastCGI, SCGI handlers for scripts, uWSGI application servers or Phusion Passenger module (atm broken in [http://funtoo.org funtoo]), further more it can serve a very capable software load balancer. It uses an asynchronos event-driven approach to handle requests which provides more predictable performance under load, in contrast to the Apache HTTP server model, that uses a threaded or process-oriented approach to handling request. Nginx is licensed under a BSD-like license and it runs on Unix, Linux, BSD variants, Mac OS X, Solaris, AIX and Microsoft Windows.
 +
 +
== Installation ==
 +
 +
=== USE flags ===
 +
 +
Before you can install nginx, there are the following USE-flags available, these can be set by ''/etc/portage/package.use'' or ''/etc/portage/package.use/nginx'', depending on your setup of package.use.
 +
 +
* aio - Enables file AIO support
 +
* debug - Enables extra debug codepaths, like asserts and extra output.
 +
* http - Enable http serving
 +
* http-cache - Enables caching for http files
 +
* ipv6 - Enables IPv6 support
 +
* libatomic - Use libatomic instead of buildtin atomic operations
 +
* pcre - Enables support for Perl Compatible Regular Expressions
 +
* ssl - Adds support for Secure Socket Layer connections
 +
* vim-syntax - Pulls in related vim syntax scripts
 +
 +
Further more you can set the nginx modules you like to use in ''/etc/make.conf'' in the NGINX_MODULES_HTTP variable as NGINX_MODULES_HTTP="variables".
 +
 +
* access
 +
* addition
 +
* auth_basic
 +
* autoindex
 +
* browser
 +
* cache_purge
 +
* charset

 +
* sub
 +
* upload
 +
* upstream_ip_hash
 +
* userid
 +
* uwsgi
 +
* xslt
 +
 +
and the following mail modules as NGINX_MODULES_MAIL in '/etc/make.conf':
 +
 +
* imap
 +
* pop3
 +
* smtp
 +
 +
=== USE Expanded flags ===
 +
 +
nginx USE-flags go into ''/etc/portage/package.use'' or ''/etc/portage/package.use/nginx'', while the HTTP and MAIL modules go as NGINX_MODULES_HTTP or NGINX_MODULES_MAIL are stored in /etc/make.conf. And as you wouldn't server only static html files, but most commonly also php files/scripts you should also install php with fpm enabled and xcache for caching the content, what makes your nginx setup way faster. For xcache you need to set PHP_TARGETS="php5-3" in '/etc/make.conf'.
 +
 +
Example:
 
<pre>
 
<pre>
# /root/git/metro/scripts/ezbuild.sh funtoo-current core2_64 openvz
+
echo "www-servers/nginx USE-FLAG-List" >> /etc/portage/package.use/nginx
 
</pre>
 
</pre>
  
== How do I build a VServer template? ==
+
=== Emerging nginx ===
  
The latest git version of metro supports vserver natively:
+
Now you are ready to install nginx with php and xcache support:
 +
<pre>
 +
emerge -avt nginx php xcache
 +
</pre>
 +
so now just check your useflags and press enter to start emerge.
 +
 
 +
== Configuring ==
 +
 
 +
All configuration is done in ''/etc/nginx'' with ''nginx.conf'' as the main configuration file and all virtual hosts in ''/etc/nginx/sites/available'' while you have to symlink ''/etc/nginx/sites-available/{VHOST}'' to ''/etc/nginx/sites-enabled/{VHOST}'' to activate them. An example config for such a {VHOST} looks like that:
  
 
<pre>
 
<pre>
# /root/git/metro/scripts/ezbuild.sh funtoo-current core2_64 vserver
+
server {
 +
    listen          80;
 +
    server_name    www.example.com;
 +
 
 +
    access_log      /var/log/nginx/www.example.com.access_log main;
 +
    error_log      /var/log/nginx/www.example.com.error_log info;
 +
 
 +
    root /var/www/www.example.com/htdocs;
 +
}
 +
</pre>
 +
 
 +
The ''nginx.conf'' and ''sites-available/localhost'' file is well commented. Customize it to your needs. Make sure you set the listen option correctly. By default, the listen option is set to listen on the loopback interface. If you leave this unchanged other computers on the network will not be able to connect to the server.
 +
 
 +
== Configuring PHP FPM ==
 +
 
 +
As we already installed php with fpm support above we just need to adjust the following settings in ''/etc/php/fpm-php5.3/php-fpm.conf''. You should enable the following settings:
 +
 
 +
<pre>
 +
user = nginx
 +
group = nginx
 +
pm.start_servers = 20
 
</pre>
 
</pre>
  
== How do I build an Linux Containers (LXC) template? ==
+
The other options should all be very well documented, so make it fit your needs.
  
The latest git version of metro supports LXC natively:
+
== Configuring xcache ==
 +
 
 +
For setting xcache just edit ''/etc/php/fpm-php5.3/ext-active/xcache''
  
 
<pre>
 
<pre>
# /root/git/metro/scripts/ezbuild.sh funtoo-current core2_64 lxc
+
zend_extension=/usr/lib64/php5.3/lib/extensions/no-debug-zts-20090626/          xcache.so                                                                 
 +
  2 xcache.admin.enable_auth="On"
 +
  3 xcache.admin.user="admin"
 +
  4 xcache.admin.pass=""
 +
  5 xcache.cacher="On"
 +
  6 xcache.size="64M"
 +
  7 xcache.count="9"
 +
  8 xcache.slots="8k"
 +
  9 xcache.ttl="0"
 +
10 xcache.gc_interval="0"
 +
11 xcache.var_size="8M"
 +
12 xcache.var_count="1"
 +
13 xcache.var_slots="8K"
 +
14 xcache.var_ttl="0"
 +
15 xcache.var_maxttl="0"
 +
16 xcache.var_gc_interval="600"
 +
17 xcache.readonly_protection="Off"
 +
18 xcache.mmap_path="/dev/zero"
 +
19 xcache.coverager="On"
 +
20 xcache.coveragedump_directory="/tmp/coverager"
 +
21 xcache.optimizer="On"
 
</pre>
 
</pre>
  
== How do I build stuff, plus an OpenVZ template? ==
+
it might look like that for you, feel free to change the settings, and if you want to be able to log in into the admin interface set the ''xcache.admin.pass'' as a md5 encrypted password you can find it out with:
  
Sometimes it's handy to be able to build a multi-target like "full" (the default stage1/2/3 build) or "freshen" ''plus'' an additional single target such as "openvz", "lxc" or "vserver". The advantage of using this approach is that the second target will only build if the first one completes successfully. Metro now accepts a "+(single-target)" to specify one additional extra target:
+
<pre>
 +
php -a
 +
php> echo md5(PASSWORD);
 +
</pre>
 +
 
 +
and copy the admin interface to your vhost:
  
 
<pre>
 
<pre>
# /root/git/metro/scripts/ezbuild.sh funtoo-current corei7 full+openvz
+
cp /usr/share/php/xcache/admin -a /var/www/{VHOST}/htdocs/xcache-admin
 
</pre>
 
</pre>
  
This comes in handy for cron jobs.
+
== Starting the service ==
  
== How do I build more than one stage a day? ==
+
Now start the services:
  
To build more than one stage a day, use the full syntax to <tt>ezbuild.sh</tt> as shown below, and specify the suffix of your preference to the datestamp. From Metro's perspective, the datestamp is just a string so anything will work -- "[today's date]-1", "test", "test-3", etc. will all be accepted by Metro. Metro will record the last stage3 built and use it as a seed stage.
+
<pre>
 +
/etc/init.d/php-fpm start
 +
/etc/init.d/nginx start
 +
</pre>
 +
 
 +
and make them default:
  
 
<pre>
 
<pre>
# /root/git/metro/scripts/ezbuild.sh funtoo-current generic_64 full 20111231-1
+
rc-update add php-fpm default
 +
rc-update add nginx default
 
</pre>
 
</pre>

What is nginx

nginx (pronounced "engin-x") is a Web and reverse proxy server for HTTP, SMTP, POP3 and IMAP protocols. It focuses on high concurrency, performance and low memory usage. Nginx quickly delivers static content with efficient use of system resources, also dynamic content is delivered on a network using FastCGI, SCGI handlers for scripts, uWSGI application servers or Phusion Passenger module (atm broken in funtoo), further more it can serve a very capable software load balancer.

Nginx is licensed under a BSD-like license and it runs on Unix, Linux, BSD variants, Mac OS X, Solaris, AIX and Microsoft Windows.

Installation

  • slowfs_cache
  • split_clients
  • ssi
  • stub_status
  • sub
  • upload
  • upstream_ip_hash
  • userid
  • uwsgi
  • xslt

and the following mail modules as NGINX_MODULES_MAIL in '/etc/make.conf':

  • imap
  • pop3
  • smtp

USE Expanded flags

nginx USE-flags go into /etc/portage/package.use or /etc/portage/package.use/nginx, while the HTTP and MAIL modules go as NGINX_MODULES_HTTP or NGINX_MODULES_MAIL are stored in /etc/make.conf. And as you wouldn't server only static html files, but most commonly also php files/scripts you should also install php with fpm enabled and xcache for caching the content, what makes your nginx setup way faster. For xcache you need to set PHP_TARGETS="php5-3" in '/etc/make.conf'.

Example:

echo "www-servers/nginx USE-FLAG-List" >> /etc/portage/package.use/nginx

Emerging nginx

Now you are ready to install nginx with php and xcache support:

emerge -avt nginx php xcache

so now just check your useflags and press enter to start emerge.

Configuring

All configuration is done in /etc/nginx with nginx.conf as the main configuration file and all virtual hosts in /etc/nginx/sites/available while you have to symlink /etc/nginx/sites-available/{VHOST} to /etc/nginx/sites-enabled/{VHOST} to activate them. An example config for such a {VHOST} looks like that:

server {
    listen          80;
    server_name     www.example.com;

    access_log      /var/log/nginx/www.example.com.access_log main;
    error_log       /var/log/nginx/www.example.com.error_log info;

    root /var/www/www.example.com/htdocs;
}

The nginx.conf and sites-available/localhost file is well commented. Customize it to your needs. Make sure you set the listen option correctly. By default, the listen option is set to listen on the loopback interface. If you leave this unchanged other computers on the network will not be able to connect to the server.

Configuring PHP FPM

As we already installed php with fpm support above we just need to adjust the following settings in /etc/php/fpm-php5.3/php-fpm.conf. You should enable the following settings:

user = nginx
group = nginx
pm.start_servers = 20

The other options should all be very well documented, so make it fit your needs.

Configuring xcache

For setting xcache just edit /etc/php/fpm-php5.3/ext-active/xcache

zend_extension=/usr/lib64/php5.3/lib/extensions/no-debug-zts-20090626/          xcache.so                                                                   
  2 xcache.admin.enable_auth="On"
  3 xcache.admin.user="admin"
  4 xcache.admin.pass=""
  5 xcache.cacher="On"
  6 xcache.size="64M"
  7 xcache.count="9"
  8 xcache.slots="8k"
  9 xcache.ttl="0"
 10 xcache.gc_interval="0"
 11 xcache.var_size="8M"
 12 xcache.var_count="1"
 13 xcache.var_slots="8K"
 14 xcache.var_ttl="0"
 15 xcache.var_maxttl="0"
 16 xcache.var_gc_interval="600"
 17 xcache.readonly_protection="Off"
 18 xcache.mmap_path="/dev/zero"
 19 xcache.coverager="On"
 20 xcache.coveragedump_directory="/tmp/coverager"
 21 xcache.optimizer="On"

it might look like that for you, feel free to change the settings, and if you want to be able to log in into the admin interface set the xcache.admin.pass as a md5 encrypted password you can find it out with:

php -a
php> echo md5(PASSWORD);

and copy the admin interface to your vhost:

cp /usr/share/php/xcache/admin -a /var/www/{VHOST}/htdocs/xcache-admin

Starting the service

Now start the services:

/etc/init.d/php-fpm start
/etc/init.d/nginx start

and make them default:

rc-update add php-fpm default
rc-update add nginx default
