1. Compile nginx with functionality.

2. Backup current configuration.

3. Install new nginx into the same place as previous version, i.e.  
overwrite old nginx binary.

4. Send USR2 signal to master nginx process [keep the PID].

5. Send WINCH signal to PID from 4.

6. If it works fine, then send QUIT to PID from 4.
