tomcat中配置限制ip

启动tomcat出错后退出，tomcat老把日志写进local_xxx.log文件里面去，很不方便，能不能直接输出在控制台上？
解决办法，改server.xml，把
        <Logger className="org.apache.catalina.logger.FileLogger"
                 directory="logs"  prefix="localhost_log." suffix=".txt"
         timestamp="true"/>
改成
        <Logger className="org.apache.catalina.logger.SystemOutLogger"
         timestamp="true"/>

 

Tomcat中限制访问者的ip或是host

<Context path="/examples" ...>
  ...
  <Valve className="org.apache.catalina.valves.RemoteHostValve"
         allow="*.mycompany.com,www.yourcompany.com"/>
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         deny="192.168.1.*"/>
  ...
</Context>
