## Deployment:

On raspberry Pi/Debian:

#If you haven't the mysql installed:
```
sudo apt install mysql-server mysql-client
```

#Create database 'modem' and import tables
```
sudo mysql -uroot -p -e "create database modem"
sudo mysql -uroot -p  modem < mysql_import.sql
```
#To fix "Ping MySQL host error:  Error 1698: Access denied for user 'root'@'localhost'"
```
sudo mysql -uroot -p < change_root_plugin.sql
```
#If your mysql root user password isn't blank, please update it from the line:

#sql.Open("mysql", "root:your_password@tcp(localhost:3306)/modem?charset=utf8")
```
nano cidmon.go
```
#Build
```
go get github.com/go-sql-driver/mysql
go get github.com/mattn/go-sqlite3
go get github.com/tarm/serial
go build
```
#run
```
sudo ./cidmon
```

### #Or if you like to use the pre-built app
```
cd /home/pi/Downloads
wget https://github.com/qienhuang/Caller_ID_on_screen/raw/master/bin/cidmon
wget https://github.com/qienhuang/Caller_ID_on_screen/raw/master/cidmon.service
```

#Run App as a service:
```
sudo mkdir -p /usr/local/cidmon && cp cidmon /usr/local/cidmon
sudo cp cidmon.service /etc/systemd/system
sudo systemctl enable cidmon.service
sudo systemctl start cidmon.service
```

On Windows stations:

Download the pre-built client from [here](https://github.com/qienhuang/Caller_ID_on_screen/raw/master/bin/cider.exe), then create a shortcut for cider.exe and add it to startup folder.

Plan for improvement:
 - MQTT with TLS secured messaging

### Others:

- [archived/cidmon.c](https://github.com/qienhuang/Caller_ID_on_screen/blob/master/archived/cidmon.c)  -The previous version of server app that written in c. Implemented serial port communication, multi-threads, tcp/udp socket, MySQL database Read/Write...
- [archived/cidmon.py](https://github.com/qienhuang/Caller_ID_on_screen/blob/master/archived/cidmon.py)  -The previous version of server app that written in Python.
