# yum info nginx Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyuncs.com * epel: mirrors.aliyuncs.com * extras: mirrors.aliyuncs.com * updates: mirrors.aliyuncs.com Installed Packages Name : nginx Arch : x86_64 Epoch : 1 Version : 1.10.1 Release : 1.el7 Size : 1.4 M Repo : installed From repo : epel Summary : A high performance web server and reverse proxy server URL : http://nginx.org/ License : BSD Description : Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and : IMAP protocols, with a strong focus on high concurrency, performance and low : memory usage.
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
