而且由于是OpenVZ架构，做SS加速不是很理想，于是便决定迁到其他VPS。

对比后，最终决定用Vultr的$5/mo 产品，可惜日本机房要绕行美国，所以选了LA的机房，不过速度还好，比DS的要快不少。

对SS做了优化后，youtube1080P无压力。

1. 更新系统

   • apt-get update
     apt-get upgrade

2. 安装MySQL

   • apt-get install mysql-server mysql-client

     MySQL 安全设置

     mysql_secure_installation

     过程中会询问是否更改 root密码，是否移除匿名用户，是否禁止root远程登录等。

3. 安装Nginx

   • apt-get install nginx
     service nginx start

     如果没有service命令，则使用

     /etc/init.d/nginx start

     直接访问IP地址，验证nginx安装是否成功
     

4. 安装PHP

   • apt-get install php5-fpm php5-gd php5-mysql php5-curl

     安装完毕之后，查看PHP的版本，验证安装是否成功 ：

     root@vultr:/www# php5-fpm -v
     PHP 5.3.10-1ubuntu3.18 (fpm-fcgi) (built: Apr 17 2015 15:08:33)
     Copyright (c) 1997-2009 The PHP Group
     Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies

5. 配置PHP-FPM
   • 编辑/etc/php5/fpm/php.ini

     vi /etc/php5/fpm/php.ini

     cgi.fix_pathinfo=0
     
     error_reporting =E_ALL | E_STRICT
     
     display_errors = On
     
     log_errors = On
     error_log = /var/log/php_error.log

   • 编辑 /etc/php5/fpm/pool.d/www.conf

     vi /etc/php5/fpm/pool.d/www.conf

     user = www-data
     group = www-data
     
     ;listen = 127.0.0.1:9000
     listen = /var/run/php5-fpm.sock
     listen.owner = www-data
     listen.group = www-data
     listen.mode = 0660
     
     pm.status_path = /fpm_status

   • 重启php5-fpm

     service php5-fpm restart

6. 配置Nginx
   • 编辑/etc/nginx/nginx.conf

     user  www-data;
     worker_processes  4;
     
     error_log  /var/log/nginx/error.log warn;
     pid        /var/run/nginx.pid;
     
     
     events {
         worker_connections  1024;
     }
     
     
     http {
         include       /etc/nginx/mime.types;
         default_type  application/octet-stream;
     
         log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                           '$status $body_bytes_sent "$http_referer" '
                           '"$http_user_agent" "$http_x_forwarded_for"';
     
         access_log  /var/log/nginx/access.log  main;
     
         sendfile        on;
         #tcp_nopush     on;
     
         keepalive_timeout  65;
     
         server_tokens off;
     
         gzip  on;
         gzip_disable "msie6";
         gzip_buffers 4 16K;
         gzip_comp_level 5;
         gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png application/javascript;
         gzip_vary on;
         include /etc/nginx/sites-available/*.conf;
     }

7. 配置网站
   • 新建/www/test目录

     mkdir /www
     mkdir /www/test

   • 新建index.php

     vi /www/test/index.php

     <?php
     
     phpinfo();
     
     ?>

   • 更改目录权限

     chown -R www-data:www-data /www/test

   • 新建网站配置

     vi /etc/nginx/conf.d/www.test.com.conf

     server {
         listen       80;
         server_name  www.test.com;
     
         access_log /var/log/nginx/www.test.com.access.log main;
         error_log  /var/log/nginx/www.test.com.error.log warn;
     
         error_page  404              /404.html;
         error_page  500 502 503 504  /50x.html;
         location = /50x.html {
             root   /usr/share/nginx/html;
         }
     
         location / {
             root /www/test;
             index  index.html index.htm index.php;
             #WordPress伪静态,不需要可以删除
             if (-f $request_filename/index.html){
                     rewrite (.*) $1/index.html break;
             }
             if (-f $request_filename/index.php){
                     rewrite (.*) $1/index.php;
             }
             if (!-f $request_filename){
                     rewrite (.*) /index.php;
             }
         }
     
         #fpm_status,可通过www.test.com/fpm_status查看fpm状态，添加?full参数可查看详细状态。
         #正式上线时需要注释掉此段
         location ~ ^/(fpm_status)$ {
          access_log off;
          include fastcgi_params;
          fastcgi_pass unix:/var/run/php5-fpm.sock;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         }
     
         location ~ \.php$ {
             proxy_buffers 8 16k;
             proxy_buffer_size 32k;
             root   /www/test;
             # With php5-fpm:
             fastcgi_pass unix:/var/run/php5-fpm.sock;
             fastcgi_index index.php;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
         }
     }
     

   • 链接到sites-available

     ln -s /etc/nginx/conf.d/www.test.com.conf /etc/nginx/sites-available/www.test.com.conf

   • 测试nginx配置

     nginx -t

     如果配置文件正常，则显示：

     nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
     nginx: configuration file /etc/nginx/nginx.conf test is successful

     如果报错，则检查配置文件

   • 待一切正常后，重启nginx

     service nginx restart

   • 此时访问www.test.com，会出现PHP运行信息
     
   • 访问 www.test.com/fpm_status 或者 www.test.com/fpm_status?full 可以查看fpm状态
