Ubuntu15.10 に nginx+php5-fpm をインストール

1.Ubuntu15は最初からApache2が入っているのでまず削除する。

sudo systemctl stop apache2.service
sudo systemctl disable apache2.service
sudo apt-get remove apache2

2.nginxとphp5-fpmインストール
sudo apt-get install nginx php5-fpm

3.nginx設定ファイル編集

/etc/nginx/sites-available/default

 location ~ \.php$ {
  include snippets/fastcgi-php.conf; #この中身を下に表示

  # With php5-cgi alone:
  # fastcgi_pass 127.0.0.1:9000;
  # With php5-fpm:
  fastcgi_pass unix:/var/run/php5-fpm.sock;
 }

snippets/fastcgi-php.conf

# regex to split $uri to $fastcgi_script_name and $fastcgi_path
fastcgi_split_path_info ^(.+\.php)(/.+)$;

# Check that the PHP script exists before passing it
try_files $fastcgi_script_name =404;

# Bypass the fact that try_files resets $fastcgi_path_info
# see: http://trac.nginx.org/nginx/ticket/321
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;

fastcgi_index index.php;
include fastcgi.conf;

3.php5-fpm設定

/etc/php5/fpm/php.ini

cgi.fix_pathinfo=0
date.timezone = Asia/Tokyo
