安装LEMP

1. 安装nginx

sudo apt-get update
sudo apt-get install nginx

2. 安装MySQL

sudo apt-get install mysql-server

sudo mysql_install_db

sudo mysql_secure_installation

3. 安装PHP并配置fpm模块

sudo apt-get install php5-fpm php5-mysql

sudo nano /etc/php5/fpm/php.ini

cgi.fix_pathinfo=0

sudo service php5-fpm restart

4. 配置nginx使用php

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

默认打开的页面如下：

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    server_name localhost;

    location / {
        try_files $uri $uri/ =404;
    }
}

我们要修改如下项：

We need to make some changes to this file for our site.

• First, we need to add an index.php option as the first value of our index directive to allow PHP index files to be served when a directory is requested.
• We also need to modify the server_name directive to point to our server's domain name or public IP address.
• The actual configuration file includes some commented out lines that define error processing routines. We will uncomment those to include that functionality.
• For the actual PHP processing, we will need to uncomment a portion of another section. We will also need to add a try_files directive to make sure Nginx doesn't pass bad requests to our PHP processor.

修改成如下页面：

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.php index.html index.htm;

    server_name server_domain_name_or_IP;

    location / {
        try_files $uri $uri/ =404;
    } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }

保存退出，重启nginx

sudo service nginx restart

5. 测试一个php脚本

sudo nano /usr/share/nginx/html/info.php

写入如下内容

保存退出，并重启nginx服务器。
用浏览器访问，可以访问到php的默认页面，成功。
