1、使用lsof -i:80查询没有监听到端口。
2、重启或重新加载nginx都报这个错误。
[root@iZ62bem75i8Z vhosts]# /alidata/server/nginx-1.4.4/sbin/nginx -s reload
nginx: [alert] kill(1668, 1) failed (3: No such process)
3、按照下面的方法处理好了。
[root@iZ62bem75i8Z vhosts]# /alidata/server/nginx-1.4.4/sbin/nginx -c /alidata/server/nginx-1.4.4/conf/nginx.conf
[root@iZ62bem75i8Z vhosts]# /alidata/server/nginx-1.4.4/sbin/nginx -s reload
[root@iZ62bem75i8Z vhosts]# lsof -i:80
