在開發板上運行boa時出現錯誤：“[boa.c:194 - unable to bind: Address already in use ”
原因：boa的端口號被佔用，需要把相應的pidkill掉：
# pgrep boa
365
# pkill boa
[01/Jan/1970:00:10:36 +0000] caught SIGTERM, starting shutdown
[01/Jan/1970:00:10:36 +0000] exiting Boa normally (uptime 626 seconds)
# pgrep boa
# boa
[01/Jan/1970:00:10:52 +0000] boa: server version Boa/0.94.13
[01/Jan/1970:00:10:52 +0000] boa: server built Sep 26 2010 at 10:03:56.
[01/Jan/1970:00:10:52 +0000] boa: starting server pid=392, port 80
出現上面的三行表示boa成功打開
