How to add Lua module to Nginx

Install lua

wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz 
tar -zxvf LuaJIT-2.0.5.tar.gz
cd LuaJIT-2.0.5
make && make install PREFIX=/usr/local/LuaJIT

etc/profile added

# lua
export LUAJIT_LIB=/usr/local/LuaJIT/lib 
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.0

source etc/profile

Download the ngx_devel_kit module

wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz

NDK (nginx development kit) module is a module that expands the core functions of nginx server. Third-party module development can be quickly implemented based on it. NDK provides functions and macros to handle some basic tasks, reducing the amount of code required for third-party module development.

Download lua-nginx-module

wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz

lua-nginx-module module enables running lua directly in nginx

View original compilation

nginx -V

like:
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_sub_module --with-http_v2_module

Enter the nginx original directory:

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_sub_module --with-http_v2_module --add-module=/root/lua-nginx-module-0.10.9rc7/ --add-module=/root/ngx_devel_kit-0.3.0

Just run make, do not execute make install.

The compilation error should be that the Lua environment variable is incorrect.

nginx -V command error./nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory

solve:
echo "/usr/local/LuaJIT/lib" >> /etc/ld.so.conf

ldconfig

After success, you can check it with nginx -V and make sure there is no error.

Back up the original nginx as nginx_old

cp objs/nginx to the original nginx and overwrite it.

Execute in the build directory

make upgrade

Nginx add lua module

test:

server{
 ...
 location /lua {
  default_type 'text/html';
  content_by_lua '
    ngx.say("hello, lua!")
  ';
 }
 ...
}

The browser opens:
