yum -y uninstall nginx

 

一、启动 

cd /usr/local/nginx/sbin
./nginx

开机自启动:

cat /etc/rc.d/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
/usr/local/nginx/sbin/nginx

直接把启动应用程序的命令放在这个文件中就可以了

 

二、重启

  更改配置重启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

判断配置文件是否正确 

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

三、关闭

  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'

四、升级

  1、先用新程序替换旧程序文件

  2、kill -USR2 旧版程序的主进程号或者进程文件名

    此时旧的nginx主进程会把自己的进程文件改名为.oldbin,然后执行新版nginx,此时新旧版本同时运行

  3、kill -WINCH 旧版本主进程号

  4、不重载配置启动新/旧工作进程

    kill -HUP 旧/新版本主进程号

    从容关闭旧/新进程

    kill -QUIT 旧/新进程号

    快速关闭旧/新进程

    kill -TERM 旧/新进程号
