There's a easiest way to solve the problem that is you have to remove the file `/home/istiak/ruby/qpixel/tmp/pids/server.pid`. Then, you can run your server again.
```bash
rm /home/istiak/ruby/qpixel/tmp/pids/server.pid
```
Otherwise, you can kill the process also. Before killing the process you have find number of the process
```bash
more /home/istiak/ruby/qpixel/tmp/pids/server.pid
```
Then, put that number on following command (instead of 2786)
```bash
kill -9 PID (eg,2786)
```
If above code doesn't work than, try following ones.
```
kill -9 $(lsof -i tcp:3000 -t)
```

You can try following code instead of above command (both are equivalent)
```bash
kill -9 $(more /home/istiak/ruby/qpixel/tmp/pids/server.pid)
```
If above code doesn't work than, try following ones.
```
kill -9 $(lsof -i tcp:3000 -t)
```
