++* How to install and run this service on Linux?
++
++Step1.Rent a Linux on Amazon cloud or alicloud to the host, and pre install the Linux system (Debian, Ubuntu, CentOS are available for distribution).
++
++Step2.Run the code on the server after compiling. Compilation requires the support of libcurl. First, compile libmqtt in the code, and then compile location.
++
++
++System: Debian / Ubuntu
++
++{{{step:
++
++1. sudo apt install libcurl4-dev
++
++2. sudo apt install  gcc automake autoconf libtool make cmake
++
++3. git clone -b master https://github.com/mikayong/location.git
++
++4. cd location/libmqtt
++
++5. mkdir build
++
++6. cd build && cmake ../
++
++7. make && sudo make install
++
++8. cd ../
++
++9. make
++
++10. sudo cp location_conf.json  /etc/
++
++11. Edit the configuration file, and run the location service in the background: ./location &}}}
++
++Step3.The location service subscribes to the lora information stream on TTN through the mqtt protocol, parses the information to generate a geographic location, and finally creates a geographic location on the mapwize map.

++* We use the 120.78.138.177 server as an example. The location service is currently installed on the 120.78.138.177 server, the code is in /root/location, and the configuration file for running location pre-read directly is /etc/location_conf.json.
