Nginx启动、重启、关闭/Nginx开启启动配置实现方式

》 cd usr/local/nginx/sbin
》 ./nginx

kill -HUP 主进程号或进程号文件路径
或者使用
》 cd /usr/local/nginx/sbin
》 ./nginx -s reload

》 nginx -t -c /usr/local/nginx/conf/nginx.conf
或者
》 cd /usr/local/nginx/sbin
》 ./nginx -t

查询nginx主进程号

　　ps -ef | grep nginx

　　从容停止   kill -QUIT 主进程号

　　快速停止   kill -TERM 主进程号

　　强制停止   kill -9 nginx

　　若nginx.conf配置了pid文件路径，如果没有，则在logs目录下

　　kill -信号类型 '/usr/local/nginx/logs/nginx.pid'

ps -ef|grep nginx
