Nginx: [Alert] Kill (2480) failed (3:no such process) solution

"Problem description"

• After you change the nginx.conf file, execute the/app/nginx/sbin/nginx-s reload command to reload the configuration file to report the following error message:

Nginx: [Alert] Kill (2480, failed) (3:no such process)

Hint that there are no related processes.

Solution

• In fact, the problem is very low, that is, I did not start the Nginx service, execute/app/nginx/sbin/nginx, open nginx Service, reload Nginx configuration, all normal!

• Close Nginx Service

2. #/app/nginx/sbin/nginx-s Stop

4. # pkill-9 Nginx force off

   Ps-ef |head-1;ps-ef |grep nginx

    # pgrep nginx

    #/app/nginx/sbin/ Nginx

    # pgrep nginx          
       2150
       2151

6. ps-a | grep Nginx | Grep-v grep | awk ' {print $;} ' |head-1 |xargs-l 1 kill-quit

   Use Xargs-l 1 to ensure that only one line of content is taken at a time, then use Kill-quit to close Nginx
   

• Start Nginx Service

1. /app/nginx/sbin/nginx

2. # Ps-ef |head-1;ps-ef |grep nginx                 
   uid        pid  ppid  C stime tty           time CMD
   root      2157     1   0 00:47?        00:00:00 nginx:master Process/app/nginx/sbin/nginx

   # kill-hup 2157
   #
   # pgrep nginx
   2157

   After you change the configuration file, you can use the kill- The HUP command reloads the configuration without stopping the original service, a bit nginx-s reload flavor.
