nginx 进程个数问题

This topic created in 1593 days ago, the information mentioned may be changed or developed.

如题，为啥 nginx.conf 里定义了 worker_processes=1 ，还是有 3 个 worker 进程？百思不得其解
root@lnxaio1:/opt/openresty/nginx/conf# grep worker_processes nginx.conf
worker_processes 1;

root@lnxaio1:/opt/openresty/nginx/conf# ps aux |grep nginx
root 13 0.0 0.0 233480 5972 ? S 18:10 0:00 nginx: master process /opt/openresty/nginx/sbin/nginx -c /opt/openresty/nginx/conf/nginx_background.conf -g daemon off;
root 14 0.0 0.1 549668 8780 ? S 18:10 0:00 nginx: master process /opt/openresty/nginx/sbin/nginx -c /opt/openresty/nginx/conf/nginx.conf -g daemon off;
root 15 0.0 0.0 141972 6296 ? S 18:10 0:00 nginx: master process /opt/openresty/nginx/sbin/nginx -c /opt/openresty/nginx/conf/nginx_console.conf -g daemon off;
nobody 60 0.0 0.0 236412 4284 ? S 18:10 0:00 nginx: worker process
root 63 0.0 0.0 145020 5020 ? S 18:10 0:00 nginx: worker process
root 65 0.1 0.2 570756 23840 ? S 18:10 0:00 nginx: worker process
root 792 0.0 0.0 14524 1008 ? S+ 18:13 0:00 grep --color=auto nginx

有三个 master process ，每个 master process 有一个 worker process ，不是很正常吗？

ps -ef| grep nginx
root 2232 1 0 17:54 ? 00:00:00 nginx: master process nginx
nginx 2233 2232 0 17:54 ? 00:00:12 nginx: worker process
root 2234 2232 0 17:54 ? 00:00:07 nginx: privileged agent process
root 2413 2342 0 18:30 pts/3 00:00:00 grep --color=auto nginx

这样可以看到每个 worker 进程对应的 master 进程 id （比如这个 2232 ）
