Ubuntu Server 16.04服务器版配置图解教程08 - nginx+php7.0基本配置

1、打开配置文件 /etc/nginx/nginx.conf：

sudo vim /etc/nginx/nginx.conf

配置是很容易理解 (你可以点击官方教程: http://wiki.nginx.org/NginxFullExample 或:http://wiki.nginx.org/NginxFullExample2)

首先（这是可选）调整keepalive_timeout到一个合理的值：

[...]
    keepalive_timeout   2;
[...]

虚拟主机服务器{}容器定义。默认的虚拟主机是在文件中定义的/etc/nginx/sites-available/default

sudo vim /etc/nginx/sites-available/default

让我们来修改它，如下所示：

[...]
server {
 listen 80 default_server;
 listen [::]:80 default_server;

 # SSL configuration
 #
 # listen 443 ssl default_server;
 # listen [::]:443 ssl default_server;
 #
 # Note: You should disable gzip for SSL traffic.
 # See: https://bugs.debian.org/773332
 #
 # Read up on ssl_ciphers to ensure a secure configuration.
 # See: https://bugs.debian.org/765782
 #
 # Self signed certs generated by the ssl-cert package
 # Don't use them in a production server!
 #
 # include snippets/snakeoil.conf;

 root /var/www/html;

 # Add index.php to the list if you are using PHP
 index index.html index.htm index.nginx-debian.html;

 server_name _;

 location / {
 # First attempt to serve request as file, then
 # as directory, then fall back to displaying a 404.
 try_files $uri $uri/ =404;
 }

 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
 #
 location ~ \.php$ {
 include snippets/fastcgi-php.conf;

 # With php7.0-cgi alone:
 # fastcgi_pass 127.0.0.1:9000;
 # With php7.0-fpm:
 fastcgi_pass unix:/run/php/php7.0-fpm.sock;
 }

 # deny access to .htaccess files, if Apache's document root
 # concurs with nginx's one
 #
 location ~ /\.ht {
  deny all;
 }
}
[...]

server_name _; 使这是一个默认捕捉所有虚拟主机（当然，你可以同时喜欢这里www.example.com指定主机名）。

根目录 /var/www/html;意味着文档根目录/var/www/html.

PHP的重要组成部分位置 ~ \.php$ {} stanza. 取消注释它来启用它。

现在保存文件并重新加载nginx：

sudo service nginx restart

下一步打开 /etc/php/7.0/fpm/php.ini…

sudo vim /etc/php/7.0/fpm/php.ini

设置 cgi.fix_pathinfo=0

[...]
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; http://php.net/cgi.fix-pathinfo
cgi.fix_pathinfo=0
[...]

重新加载 PHP-FPM:

sudo service php7.0-fpm restart

建立探针文件/var/www/html:

vim /var/www/html/info.php

<?php
phpinfo();
?>
