一、首先需要去国内相关镜像库下载相关依赖rpm：

注意：1、博主是下载上面了这些包，实际看自己服务器具体缺失的包，可能需要增加一些
2、上面命令是下载好的包，上传到服务器执行安装的命令
三、去官网下载最新的nginx
四、编译安装nginx
#进入
cd /home/nginx
#解压
tar -zxvf nginx-1.22.1.tar.gz
#进入文件夹
/home/nginx/nginx-1.22.1
#不用开启https
./configure
#需要开启https，--with-openssl路径需要根据自己实际情况配置
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-openssl=/home/nginx/nginxarm/openssl-1.1.1l
make
make install
注意：--with-openssl=/home/nginx/nginxarm/openssl-1.1.1l里面的openssl可以根据自己实际情况配置，博主配置是因为已经安装了openssl，但是编译还是提示找不到路径，所以去官网下载了一个openssl进行编译，官网地址：https://www.openssl.org/source/
其他说明：这是arm架构离线安装nginx，如果是x86离线安装的话，镜像库选择就需要是x86镜像库：CentOS Mirror
