setup temporary nginx and additional nginx module

• info about ngx_http_echo_module: https://github.com/openresty/echo-nginx-module#installation
• create dir for tmp nginx installation:
  • mkdir tmp + cd tmp + mkdir nginx + cd nginx
• pwd-> /home/max/Documents/AWT/tmp/nginx -> copy path for later
• cd ~/Downloads
• download nginx module:
  • wget 'https://github.com/openresty/echo-nginx-module/archive/refs/tags/v0.62.tar.gz'
• tar xf v0.62.tar.gz
• cd echo-nginx-module-0.62/
• pwd -> /home/max/Downloads/echo-nginx-module-0.62 -> copy path for later -> cd ..
• download file for temporary nginx installation -> same version as current global nginx installation❗ (nginx -v):
  • wget 'http://nginx.org/download/nginx-1.22.0.tar.gz'
• tar xf nginx-1.22.0.tar.gz
• cd nginx-1.22.0/
• install nginx with downloaded module into temporary folder
  • ./configure --with-compat --prefix=/home/max/Documents/AWT/tmp/nginx --add-dynamic-module=/home/max/Downloads/echo-nginx-module-0.62
    • possible PCRE library error -> sudo apt install libpcre3 libpcre3-dev, then run ./configure command again
    • possible zlib error -> sudo apt install zlib1g-dev andsudo apt install zlib1g, then run ./configure command again
  • make -j2
  • make install
