Pid File Run Nginx Pid Not Readable Yet After Start

After a stop, you don't have a running nginx process to send a signal to. Just run nginx (possibly with a -c /path/to/config/file) share|improve this answer answered Oct 4 '11 at 11:51 kolbyjack 8,31942426 On a stock installation of of current distributions, you will probably want to use the start script: sudo service nginx start –MattW. Apr 27 at 9:49 add a comment| up vote 11 down vote in my case I solved this by starting the service. sudo /etc/init.d/nginx start The command above will start the service in Debian/Ubuntu. It will issue an error if there is any problem (like Apache listening in the same port) After that nginx -s reload will work like a charm share|improve this answer answered Dec 4 '11 at 13:44 Adrián Deccico 4,07221426 add a comment| up vote 6 down vote In the latest ver

Failed To Read Pid From File Invalid Argument
Assignees No one assigned 3 participants fschwiet commented Aug 15, 2014 After running the nginx recipe, I write some config rules to /etc/nginx/conf.d. These changes don't take effect until I reboot http://stackoverflow.com/questions/7646972/nginx-invalid-pid-number the system. "sudo nginx -s reload" fails claiming it can't find nginx.pid. How can I get nginx to see the config changes? miketheman added the question label Aug 23, 2014 miketheman added this to the Triage milestone Aug 23, 2014 Owner miketheman commented Aug 23, 2014 @fschwiet How are you writing these rules? Via a template or file resource? Also, the command you are probably https://github.com/miketheman/nginx/issues/256 looking for is sudo service nginx reload instead of using the nginx binary directly. fschwiet commented Aug 23, 2014 Thanks. I thought I tried something like that in the past, but it works now, so great. I am creating the rules from a bash script, I want to change such rules after vagrant/chef are out of the picture for the machine. fschwiet closed this Aug 23, 2014 fschwiet reopened this Aug 25, 2014 fschwiet commented Aug 25, 2014 Hmm, it turns out that though sudo service nginx reloads will succeed before rebooting, the nginx configuration change does not kick in until I reboot. After I reboot, the rule works, and I can change the rule and sudo service nginx reload will then pick up the change. It seems like nginx is running before I reboot because the error page I get before rebooting is served by nginx. The new nginx rule I am adding is a new file in /etc/nginx/conf.d/, in case that matters. I could put together a vagrant based repro if someone wants to take a look. The repo would require vagrant/virtualbox and takes over 5 minutes to run. fschwiet comme

You can check with ps -ef | grep nginx or sudo netstat -tlnp | grep nginx. –Ladadadada Jan 6 '14 at 16:18 Thanks for your advice. I added result of ps command. –ironsand Jan 7 '14 at 7:
Administrator Stop Operation Stop operation by sending a signal to a process to nginx Step 1 : Check the main process nginx No. ps-ef | grep nginx Find a master list of processes inside the process , it is the main process ID number. Step 2: transmission signal Calmly stop Nginx: kill-QUIT main process ID Quick Stop Nginx: kill-TERM main process ID Forced to stop Nginx: pkill -9 nginx In addition, if the pid nginx.conf configuration file storage path , the file is stored in the main process Nginx number, if it is not specified in the nginx logs directory. With the pid file , we do not first check Nginx master process number , and send signals directly to Nginx , and command is as follows : kill - signal type '/ usr / nginx / logs / nginx.pid' Graceful Restart If you change the configuration necessary to restart Nginx, Nginx first close and then open ? No, you can send a signal to Nginx, smooth restart. Graceful Restart command: kill-HUP admitted to the file path name or process ID Or use / usr / nginx / sbin / nginx-s reload The best note , modify the configuration file first and then check the modified configuration file is correct , in order to avoid errors after restarting the affected server Nginx stable operation . Nginx configuration to determine whether the correct commands are as follows : nginx-t-c / usr / nginx / conf / nginx.conf Or / usr / nginx / sbin / nginx-t Smooth upgrade If the server is running Nginx to upgrade , add or remove modules, we need to quit the server and make the appropriate changes, so that the server is necessary to stop the service for a period of time , Nginx can make various upgrades in the case of non-stop action of without affecting the servers running . Step 1: If Nginx upgrade program, the first program to replace the old file with the new program , then compile and install new programs directly compiled into Nginx installation directory. Step 2 : Run the command kill-USR2 legacy program's main process ID or process file name At this point the old Nginx master process will bring its own process file was renamed . Oldbin, and then perform a new version of Nginx. Nginx is running in conjunction with the old and new city together to process the request . Then to
