nginx: [alert] kill(1022, 1) failed (3: No such process)，nginx1022

安装完nginx，想修改端口，于是在修改nginx的/usr/local/nginx/conf/nginx.conf（配置文件）后，重新启动nginx（[root@192 sbin]# ./nginx -s reload）后出现了以下错误
nginx: [alert] kill(1022, 1) failed (3: No such process)

以下是解决方法：

[root@192 Desktop]# ll /usr/local/nginx/sbin/nginx
-rwxr-xr-x. 1 root root 2597931 Dec 15 19:09 /usr/local/nginx/sbin/nginx

[root@192 Desktop]# whereis nginx
nginx: /usr/local/nginx

[root@192 Desktop]# find / -name nginx
/usr/local/src/nginx-1.1.10/objs/nginx
/usr/local/nginx
/usr/local/nginx/sbin/nginx

[root@192 Desktop]# find / -name nginx.conf
/usr/local/src/nginx-1.1.10/conf/nginx.conf
/usr/local/nginx/conf/nginx.conf

打开/usr/local/nginx/sbin目录，启用并重启nginx
[root@192 Desktop]# cd /usr/local/nginx/sbin

启动代码格式：nginx安装目录地址 -c nginx配置文件地址
[root@192 sbin]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

重启nginx
[root@192 sbin]# ./nginx -s reload
[root@192 sbin]#
