tomcat7埠改為80後無法正常監聽80埠，檢視日誌檔案/var/log/tomcat7/catalina.XX.log報錯資訊如下:

解決:
1. /etc/tomcat7/server.xml中將埠8080改為80:
Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
URIEncoding="UTF-8"
redirectPort="8443" />
2. tomcat7使用<1024的埠需要root許可權，因此需要修改檔案/etc/default/tomcat7中如下內容:
TOMCAT7_USER=root
TOMCAT_GROUP=root
AUTHBIND=yes
3. 重啟tomcat7服務
/etc/init.d/tomcat7 restart
netstat -anupt | grep 80
