在CentOS 5.5版本的端口80上启动tomcat(Final)

我想在端口80上启动Tomcat 6.0.29.
我的操作系统是CentOS 5.5版(Final)
我在$TOMCAT_HOME / conf / server.xml中更改了以下行

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

至

<Connector connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443"/>

然后我运行命令：

sudo /etc/init.d/tomcat6 start

在文件$TOMCAT_HOME / logs / catalina.log中我发现了这样的异常：

提前致谢

1-1023范围内的端口是特权的.只有root可以绑定到它们.

至少有两种方法来解决这个问题：

>以root身份运行.当然,你需要重视这个推测的额外的安全隐患; Tomcat本身的两个安全漏洞(我相信很少)和您的Web应用程序包含(例如可以让人们以/ etc / shadow为例),这样做简单直观.
>以jsvc作为服务运行.有关jsvc的详细信息,请参见http://tomcat.apache.org/tomcat-5.5-doc/setup.html.这是一些额外的麻烦设置,但是root只会参与设置端口,Tomcat然后将作为用户运行而没有特殊权限.我建议这个任何严重的设置.

无论您选择什么方式,Tomcat的实际启动都将需要root权限.
