How to config VPS / VDS server for Debian & Ubuntu

I decided to write this article in order to gather all the information on this subject in one place. Many questions arise to optimize server. Tell you how I achieved the speed of page loading for 0.013 seconds. So. We have a clean Debian or Ubuntu.

We will install and configure:

Apache 2

PHP 5

MySQL 5

nginx

memcached

eAcellerator

Sphinx

Will write for debian, just 6 for Debian, almost all the same.

Hope that we have a network already configured.

Install LAMP

apache2 php5 php5-mysql mysql-server–5.0.

Install nginx.

All put out off repository

apt-get install nginx libapache2-mod-rpaf

Hang Apache on a different port, for example 81 (can the 8080, doesn’t matter):

$ nano/etc/apache2/ports.conf

In the assign file:

Listen *: 81

Next, configure the virtual host apache.

Copy the default config:

$ cd/etc/apache2/sites-available

$ sudo cp/default domain.ru/etc/apache2/sites-enabled/.

Edit config virtualhosta Apache:

$ nano/etc/apache2/sites-enabled/domain.ru

<VirtualHost *:81>

ServerName www.example.com

ServerAlias example.com

ServerAdmin [email protected]

DocumentRoot /var/www/example.com

<Directory /var/www/example.com>

Options Indexes FollowSymLinks MultiViews

AllowOverride All

Order allow,deny

allow from all

</Directory〉

ErrorLog /var/log/apache2/error.log

LogLevel warn

ServerSignature On

</VirtualHost>

Configure gzip compression for nginx. Open the config:

$ nano/usr/local/etc/nginx/nginx.conf

My config looks like this:

user www-data;

worker_processes  1;

error_log  /var/log/nginx/error.log;

pid        /var/run/nginx.pid;

events {

worker_connections  1024;

}

http {

include       /etc/nginx/mime.types;

default_type  application/octet-stream;

server_names_hash_bucket_size 64;

access_log  /var/log/nginx/access.log;

sendfile        on;

#tcp_nopush     on;

#keepalive_timeout  0;

keepalive_timeout  65;

tcp_nodelay        on;

gzip                on;

gzip_proxied        any;

gzip_min_length     1100;

gzip_http_version   1.0;

gzip_buffers        4 8k;

gzip_comp_level     9;

gzip_types          text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

include /etc/nginx/conf.d/*.conf;

include /etc/nginx/sites-enabled/*;

}

# Enable compression for all proxied requests

gzip_proxied any;

# MIME types that you want to press

gzip_types text/plain text/html, text/xml, application/xml, application/x-javascript text/javascript, text/css, text/json;

# Gzip compression Level (I have 9, i.e. the maximum compression, as resources allow)

gzip_comp_level 8;

To create a new virtualhosta config:

$ nano/etc/nginx/sites-enabled/domain.ru

server {

listen 80;

server_name domain.ru;

access_log /var/log/nginx/domain.ru-nginx.access.log;

location / {

proxy_pass http://127.0.0.1:81/;

proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 40m;

client_body_buffer_size 256k;

proxy_connect_timeout 120;

proxy_send_timeout 120;

proxy_read_timeout 120;

proxy_buffer_size 64k;

proxy_buffers 4 64k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

#Static files location

location ~* ^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|html|flv|mp3)$ {

root /var/www/domain.ru; }

}

Check config nginx:

$ nginx–t

Install memcached:

$ apt-get install memcached

Memcached configuration is located at/etc/php5/conf.d/memcache.ini

Getting change anything is not worth it.

Install eAccelerator.

Just pull php5-dev, because we need the utility phpize.

$ sudo apt-get install php5-dev

$ sudo apt-get install make

$ sudo cd /tmp/

$ sudo wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.tar.bz2

$ sudo tar xvjf eaccelerator-0.9.5.3.tar.bz2

$ sudo cd eaccelerator-0.9.5.3

$ sudo phpize

$ sudo ./configure --enable-eaccelerator=shared

$ sudo make

$ sudo make install

Create a cache folder:

$ sudo mkdir -p /var/cache/eaccelerator

$ sudo chmod 0777 /var/cache/eaccelerator

Edit config PHP:

$ nano /etc/php5/apache2/php.ini

Add a line at the top:

[PHP]

; eAccelerator configuration

; Note that eAccelerator may also be installed as a PHP extension or as a zend_extension

; If you are using a thread safe build of PHP you must use

; zend_extension_ts instead of zend_extension

extension                       = "eaccelerator.so"

eaccelerator.shm_size           = "16"

eaccelerator.cache_dir          = "/var/cache/eaccelerator"

eaccelerator.enable             = "1"

eaccelerator.optimizer          = "1"

eaccelerator.check_mtime        = "1"

eaccelerator.debug              = "0"

eaccelerator.filter             = ""

eaccelerator.shm_max            = "0"

eaccelerator.shm_ttl            = "0"

eaccelerator.shm_prune_period   = "0"

eaccelerator.shm_only           = "0"

eaccelerator.compress           = "1"

eaccelerator.compress_level     = "9"

eaccelerator.allowed_admin_path = "/var/www/eaccelerator"

Attention!

If you have enough RAM, then recommend a bytecode cache mode solely in RAM:

eaccelerator.shm_only = “1”

As well as increase the available memory for cache:

eaccelerator.shm_size = “128”

Also in the package there is a file aksselleratora control.php, which you can manage the cache and analyze errors, which is very convenient. Put this file it is necessary on the way

eaccelerator.allowed_admin_path = “/var/www/eaccelerator”

Otherwise it will throw errors.

Next install Sphinx.

Why, I repeat, because this has already been written a couple of posts (by the way online manuals Poti not)? Answer: I am faced with such problems, which do not obhvačeny, so am writing because these moments.

Pull the source code (no package repositories), unpack and install:

$ wget http://www.sphinxsearch.com/downloads/sphinx-0.9.8.1.tar.gz

$ tar –xzvf sphinx-0.9.8.tar.gz

$ cd sphinx-0.9.8

$ ./configure

$ make

$ make install

$ mkdir -p /var/db/sphinx/log

$ chmod -R 777 /var/db/

Next, edit the configuration file, kindly compiled by kruft’om (for which he, or not to him, but going thanks), but I will give a fully working immediately and ready version (version of the author’s article is not relevant and requires dopilivaniâ):

$ nano /usr/local/etc/sphinx.conf

Do not forget to write the MySQL settings.

Next, create a folder for the database index and set write permissions:

$ mkdir -p /usr/local/SphinxIndex

$ chmod -R 777 /usr/local/SphinxIndex/

Run the indexing:

$ /usr/local/bin/indexer –all

Start the daemon:

$ /usr/local/bin/searchd

This means that we will start indexing every 3:0.

$ nano /etc/crontab

Добавляем:

0 */3 * * * /usr/local/bin/indexer –all –rotate
Это значит, что мы будем запускать индексацию каждые 3 часа.

Перезапускаем сервисы:

$ service apache2 restart

$ service nginx restart

$ service memcached restart

The SIM everything should work.

Check the workability of the ports (PID and DEVICE of course may be different):

lsof -i

We should see the following line:
