linux+tomcat配置域名访问指定项目，不用接项目名

直接上码，tomcat/conf/server.xml配置如下：

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
<Listener className="org.apache.catalina.core.JasperListener" />
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

<GlobalNamingResources>

<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>

<Service name="Catalina">

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="443" URLEncoding="utf-8"/>

<Engine name="Catalina" defaultHost="www.lyitong.com">

<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>

<Host name="www.lyitong.com"  appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="/usr/local/tomcat/webapps/lyitong/"/>

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />

</Host>

<Context path ="" docBase="/"  debug="0" reload ="true"/>
<Host name="m.lyitong.com" appBase="webapps1" unpackWARs="true" autpDeploy="true">

</Host>
</Engine>
</Service>
</Server>

注：记得把tomcat/webapps下的这几个系统默认的文件夹删除以免冲突：



配置好后基本可用了，如果还有别的默认页面，可以继续加context标签和相似的配置即可
