195 * How to install and run this service on Linux?
196
197 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).
198
199 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.
200
201
202 System: Debian / Ubuntu
203
204 {{{step:
205  
206 1. sudo apt install libcurl4-dev 
207  
208 2. sudo apt install  gcc automake autoconf libtool make cmake
209  
210 3. git clone -b master https://github.com/mikayong/location.git
211  
212 4. cd location/libmqtt
213  
214 5. mkdir build
215  
216 6. cd build && cmake ../
217  
218 7. make && sudo make install 
219  
220 8. cd ../
221  
222 9. make 
223  
224 10. sudo cp location_conf.json  /etc/
225  
226 11. Edit the configuration file, and run the location service in the background: ./location &}}}
227
228 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. The following is the configuration of the location service, the configuration file is in json format, the file is /etc/location_conf.json
