Steps of installing

    1. download https://openresty.org/download/openresty-x.y.z.a.tar.gz .
    2. install openresty.
    3. To copy all files in lualib to directory openresty/lualib/
    4. To cpoy all conf file to directory openresty/nginx/conf/
    5. compile source in directory openresty/lualib/libthrift/c
        cd /usr/local/openresty/lualib/libthrift/c ; make
    6. Start openresty nginx server.
