Nginx -- 09 -- nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"

最近在重启nginx服务时，碰到了以下的错误

nginx: [error] invalid PID number “” in “/usr/local/nginx/logs/nginx.pid”

解决办法是，先杀掉进程，然后启动时重新设置配置文件

• ps -ef | grep nginx

• kill -9 28282 28283

• ./usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
