最近需要用到 Openwrt/Lede 下的 nginx，opkg install nginx 安装的包并不支持 https 和 http2，需要自己编译，尝试用英文记录：

Install nginx adopt this command in openwrt:

opkg install nginx

But this nginx version without http_ssl_module,that means it does not support HTTPS.

Cross-compile nginx:

Prerequisites:

Do everything as non-root user!
Don't compile in Linux Subsystem on Windows 10
1-4 GB of RAM to build Openwrt

1. Install build tools to do the cross-compilation process

   apt-get install git-core build-essential libssl-dev libncurses5-dev unzip gawk zlib1g-dev subversion libncurses5-dev gcc-multilib flex gettext  mercurial
   
   

2. Download the OpenWrt source code

   git clone https://github.com/openwrt/openwrt.git
   

3. Setup the Build System,select your router types like this

   cd openwrt  
   make menuconfig  

   

   make V=s
   

   make V=s may spend half an hour...

4. Compile nginx ipk

   scripts/feeds update
   scripts/feeds search nginx
   scripts/feeds install nginx
   make menuconfig
       network
           Web Servers/Proxies
               nginx : select M
                  nginx: ENTER
                       Configuration
                       Enable SSL module : Y
                       save & exit
   time make -j5

   If you want to deploy HTTP2, choose Enable http_v2_module at the sametime.
   Compile peocess may spend 10 minutes.

5. Then search nginx ipk file,copy it to router and install

   find . -type f -name nginx\*ipk
   

   You can use the "ssl on" directive in /etc/nginx/nginx.conf.
