           proxy_set_header HOST $http_host;
           proxy_set_header X-NginX-Proxy true;
   
           proxy_pass http://thumbor;
           proxy_redirect off;
       }
   }

4. Install Thumbor Lib

   pip install pycurl numpy
   pip install thumbor==4.12.2
   

5. create file optimizer plugins pngcrush for png
   

   nano /usr/local/lib64/python2.7/site-packages/thumbor/optimizers/pngcrush.py

   paste this

           self.pngcrush_path = self.context.config.PNGCRUSH_PATH
           if not (os.path.isfile(self.pngcrush_path) and os.access(self.pngcrush_path, os.X_OK)):
               logger.error("ERROR pngcrush path '{0}' is not accessible".format(self.pngcrush_path))

           with open(os.devnull) as null:
               subprocess.call(command, shell=True, stdin=null)

   Generate Config file
   

   thumbor-config > /etc/thumbor.conf

   change LOADER in file thumbor.conf for load file image from server
   

   LOADER = 'thumbor.loaders.file_loader'
   

6. enable Optimizer in thumbor.conf
   

   OPTIMIZERS = [
       'thumbor.optimizers.jpegtran',
       'thumbor.optimizers.pngcrush',
   ]
   
   JPEGTRAN_PATH = '/usr/bin/jpegtran'
   PNGCRUSH_PATH = '/usr/bin/pngcrush'

7. Install & configure supervisor
   

   easy_install supervisor

   create file /etc/init.d/supervisord
   

   #! /bin/sh
   ### BEGIN INIT INFO

   ARGS="-c /etc/supervisord.conf"
   
   case $1 in
   start)
           echo -n "Starting supervisord: "
           $SUPERVISORD $ARGS
           echo

           echo
           echo -n "Starting supervisord: "
           $SUPERVISORD $ARGS
           echo
           ;;
   esac
   

   create file /etc/supervisord.conf and paste
   

   [unix_http_server]
   file=/tmp/supervisor.sock   ; (the path to the socket file)

   ; the below section must remain in the config file for RPC

   supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
   
   [supervisorctl]
   serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket

   ; processes, however we want the same setup for each so that isn't necessary
   ; command=thumbor --ip=127.0.0.1 --port=800%(process_num)s --conf=/etc/thumbor800%(process_num)s.conf

   stderr_logfile=/var/log/thumbor.stderr.log  
   stderr_logfile_maxbytes=1MB  
   stderr_logfile_backups=10
   

   start supervisord and nginx
   

   chmod +x supervisord ; /etc/init.d/supervisord start; /etc/init.d/nginx start

8. optional for custom or change unsafe url add in nginx thumbor configuration
   

     location ~* /thumb/(.*)/(.*\.(jpg|jpeg|png|gif|JPG))$ {
   
           proxy_pass http://localhost:8000/unsafe/$1/$2;
       }

    change url http://localhost:8000/unsafe/300x300/file.jpg to
   http://localhost:8000/thumb/300x300/file.jpg
