1、确认当前nginx版本信息

进入nginx安装目录下, 执行

./sbin/nginx -V

可以看到当前nginx的版本信息

nginx version: nginx/1.17.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) 
built with OpenSSL 1.1.1i  8 Dec 2020
TLS SNI support enabled
configure arguments: --prefix=/extusr/software/nginx --with-http_ssl_module --with-stream --with-pcre=/extusr/software/nginx-install-package/pcre-8.42 --with-zlib=/extusr/software/nginx-install-package/zlib-1.2.11 --with-openssl=/extusr/software/nginx-install-package/openssl-1.1.1i --add-module=/extusr/software/nginx-install-package/ngx_http_proxy_connect_module-master

2、去nginx官网下载想要升级的tar包

4、安装包解压

tar zxvf nginx-1.21.6.tar.gz

解压之后进入安装目录

cd nginx-1.21.6

5、安装文件编译

patch -p1 < /extusr/software/nginx-install-package/ngx_http_proxy_connect_module-master/patch/proxy_connect_rewrite_102101.patch

./configure --prefix=/extusr/software/nginx --with-http_ssl_module --with-stream --with-pcre=/extusr/software/nginx-install-package/pcre-8.42 --with-zlib=/extusr/software/nginx-install-package/zlib-1.2.11 --with-openssl=/extusr/software/nginx-install-package/openssl-1.1.1i --add-module=/extusr/software/nginx-install-package/ngx_http_proxy_connect_module-master

make

6、升级NG

mv /extusr/software/nginx/sbin/nginx /extusr/software/nginx/sbin/nginx-1.17.1

cp objs/nginx /extusr/software/nginx/sbin/

kill -USR2 `cat /extusr/software/nginx/logs/nginx.pid`

kill -WINCH `cat /extusr/software/nginx/logs/nginx.pid.oldbin`

7、验证升级后的版本

执行

./sbin/nginx -V

可以看到nginx的版本信息已成功升级为1.21.6。至此，大功告成！
