tomcat部署多项目server.xmll配置

 首先，我们以windows为例，其他系统类似。

 第一种情况：多项目使用同一域名，我们以两个项目为例。

 为了配置方便， 我们先把这两个项目的war包放到tomcat的webapps目录下。

 我们现在看一下配置：

</Server>

我们再看一下不同项目使用不同域名，以两个项目为例：

<?xml version='1.0' encoding='utf-8'?>

<Server port="8007" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />

<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
<!--Initialize Jasper prior to webapps are loaded. Documentation at /docs/jasper-howto.html -->
<Listener className="org.apache.catalina.core.JasperListener" />
<!-- Prevent memory leaks due to use of particular java/javax APIs-->
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

<!-- Global JNDI resources

-->
<GlobalNamingResources>
<!-- Editable user database that can also be used by

-->
<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>

<!-- A "Service" is a collection of one or more "Connectors" that share

so you may not define subcomponents such as "Valves" at this level.

-->
<Service name="Catalina">
<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
</Realm>

<!-- 访问路径：www.test.com.cn -->
<Host name="www.test.com.cn" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Context path="/" docBase="D:\tomcat\webapps\test-three" allowLinking="true" />

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

</Host>

<!-- 访问路径：www.test2.com.cn -->
<Host name="www.test2.com.cn" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Context path="/" docBase="D:\tomcat\webapps\test-four" allowLinking="true" />

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

</Host>

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

我们启动服务器就可以访问了。
