Nginx

指令

• nginx -s stop – 快速的停止Nginx
  
• nginx -s quit – 优雅的停止Nginx
  
• nginx -s reload – 重载配置文件
  
• nginx -s reopen – 重新打开日志
  

  注意

  location /img/ {
  alias /var/www/image/;
  }
  #若按照上述配置的话，则访问/img/目录里面的文件时，ningx会自动去/var/www/image/目录找文件
  location /img/ {
  root /var/www/image;
  }
  #若按照这种配置的话，则访问/img/目录下的文件时，nginx会去/var/www/image/img/目录下找文件。]

FastDFS

1、启动storaged
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart

2、启动storaged
vi /etc/fdfs/storage.conf
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart

为什么要用FastDFS呢？
