1.删除Apache

sudo service apache2 stop
update-rc.d -f apache2 remove
sudo apt-get remove apache2

删除完之后，更新一下包列表
sudo apt-get update

2.Nginx

• 安装

sudo apt-get install Nginx

• 使用

sudo service Nginx start //启动
sudo service Nginx restart //重启
sudo service Nginx status //查看状态

在浏览器地址栏输入公网IP，你就可以看的welcome to Nginx的界面了

3.PHP

• 安装

sudo apt-get install PHP5-fpm PHP5-cli PHP5-mcrypt

• 配置

sudo vim /etc/PHP5/fpm/PHP.ini
//打开PHP配置文件，找到cgi.fix_pathinfo选项，去掉它前面的注释分号;，然后将它的值设置为0,如下
cgi.fix_pathinfo=0

5.启用PHP5-mcrypt:

sudo PHP5enmod mcrypt

6.重启PHP5-fpm:

sudo service PHP5-fpm restart

在搭建完LEMP环境之后，首先要明确两个重要目录
Nginx的默认root文件夹
/usr/share/Nginx/html

Nginx的服务器配置文件所在目录
/etc/Nginx/sites-available/


ThinkPHP Nginx配置

server {

    listen 80 default_server;
  listen [::]:80 default_server ipv6only=on;
root /var/www/jiajiao-web-test/;

index index.PHP  index.html index.htm;
Make site accessible from http://localhost/
server_name jiajiaodaojia.cn;
location / {
      root /var/www/jiajiao-web-test/;
      # First attempt to serve request as file,then
      # as directory,then fall back to index.html
      try_files $uri $uri/ /index.html;

      # include /etc/<a href="https://www.jb51.cc/tag/Nginx/" target="_blank" class="keywords">Nginx</a>/naxsi.rules
      if (!-e $request_filename)

              break;
      }

}
