2、无感升级niginx

1.下载新版本
wget http://nginx.org/download/nginx-1.21.4.tar.gz

2.解压
tar -zxf nginx-1.21.4.tar.gz

3.查看老版本Nginx信息 ./nginx -V

4.新版本目录编译Nginx ./configure 后面填写上述信息 ↑
./configure —prefix=/usr/local/nginx —pid-path=/var/run/nginx/nginx.pid —lock-path=/var/lock/nginx.lock —error-log-path=/var/log/nginx/error.log —http-log-path=/var/log/nginx/access.log —with-http_gzip_static_module —http-client-body-temp-path=/var/temp/nginx/client —http-proxy-temp-path=/var/temp/nginx/proxy —http-fastcgi-temp-path=/var/temp/nginx/fastcgi —http-uwsgi-temp-path=/var/temp/nginx/uwsgi —with-http_stub_status_module —with-http_ssl_module —http-scgi-temp-path=/var/temp/nginx/scgi

完成后执行 make

5.备份老版本nginx启动脚本
mv nginx nginx_old

6.拷贝新版本Nginx目录下obj目录下的nginx到nginx的sbin目录下
cp objs/nginx /usr/local/nginx/sbin/nginx

7.回到新版本目录下执行 make upgrade

8.查看nginx的升级信息
nginx -V 、 nginx -t
