Q: When I startup iServer on Linux, why it reported that the port is occupied?

A: There are two ways to solve this problem:

1. Modify the port number: open "[installation directory]\conf\server.xml", modify the 8090 boot port and 8015 shutdown port to another value.

2. You can use command "lsof tcp:8090" to see which program occupies this port number. If this program can be closed, then execute "kill-9 [pid]".
