make

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
[root@www nginx-1.14.0]# cp objs/nginx /usr/local/nginx/sbin/nginx

[root@www nginx-1.14.0]# /usr/local/nginx/sbin/nginx -t

kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`


[root@www nginx-1.14.0]# ps -ef | grep nginx

kill -WINCH `cat /usr/local/nginx/logs/nginx.pid.oldbin` 
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
