一、概述

方式一、同一個Tomcat 同一個端口部署多個項目

步驟一、默認tomcat支持多應用部署，將多個war包放置在tomcat下的webapps下即可

docker啟動

docker run -d --name tomcat8 -p 8083:8080 -v /Users/lihongxu6/docker/tomcat8/webapps:/usr/local/tomcat/webapps \
-v /Users/lihongxu6/docker/tomcat8/conf/server.xml:/usr/local/tomcat/conf/server.xml tomcat:8.5.40-jre8

步驟二、通過server查看基礎配置

<?xml version="1.0" encoding="UTF-8"?>

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!-- 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
       Documentation at /docs/jndi-resources-howto.html
  -->
  <GlobalNamingResources>
    <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users
    -->
    <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 port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">

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

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

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

可以看到監聽端口為：8080，部署appBase 為webapps

訪問：【這里docker映射了8080到8083】

http://localhost:8083/test/aaa/index.html

http://localhost:8083/test1/index.html

http://localhost:8083/test2/index.html

步驟三、自定義虛擬路徑

上述訪問比較麻煩，規划成如下訪問

http://localhost:8083/test/aaa/index.html http://localhost:8083/auth/index.html

http://localhost:8083/test1/index.html 　　http://localhost:8083/data/index.html

http://localhost:8083/test2/index.html 　　http://localhost:8083/code/index.html

配置server.xml，在上述Host配置

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

        <Context docBase="test/aaa" path="/auth" reloadable="true" />
        <Context docBase="test1" path="/data" reloadable="true" />
        <Context docBase="test2" path="/code" reloadable="true" />
      </Host>

再次訪問上述代碼即可。

path屬性:指定訪問該Web應用的URL入口。如“/auth/”

docBase屬性:指定Web應用的文件路徑，可以給定絕對路徑，可以給定相對路徑。。如應用test1的文件路徑為<CATALINA_HOME>/webapps/test1

reloadable屬性:如果這個屬性設為true，tomcat服務器在運行狀態下會監視在WEB-INF/classes和WEB-INF/lib目錄下class文件的改動，如果監測到有class文件被更新的，服務器會自動重新加載Web應用。

方式二、同一個Tomcat 多個端口部署多個項目

步驟一、$TOMCAT_HOME 路徑下新建文件夾webapps1，里面放要發布的項目 .war文件

　　Tomcat默認空間webapps，增加一個項目運行可以新建一個名為webapp-data(或者其他看實際情況)的文件夾，然后加入你要部署的新項目(myProject1)。

步驟二、更改conf中的配置文件：server.xml

新增Service節點

<?xml version="1.0" encoding="UTF-8"?>

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!-- 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" />

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

    <Engine name="Catalina" defaultHost="localhost">

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

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

        <Context docBase="test/aaa" path="/auth" reloadable="true" />
        <Context docBase="test1" path="/data" reloadable="true" />
        <Context docBase="test2" path="/code" reloadable="true" />
      </Host>
    </Engine>
  </Service>
  <Service name="Catalina">
    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8444" />

    <Engine name="Catalina" defaultHost="localhost">

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

      <Host name="localhost"  appBase="webapps-data"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

        <Context docBase="test/aaa" path="/auth1" reloadable="true" />
        <Context docBase="test1" path="/data1" reloadable="true" />
        <Context docBase="test2" path="/code1" reloadable="true" />
      </Host>
    </Engine>
  </Service>
</Server>

步驟三、docker啟動

docker run -d --name tomcat82 -p 8081:8081 -p 8082:8080 --privileged=true -v /Users/lihongxu6/docker/tomcat8/webapps:/usr/local/tomcat/webapps \
-v /Users/lihongxu6/docker/tomcat8/webapps-data:/usr/local/tomcat/webapps-data -v /Users/lihongxu6/docker/tomcat8/conf/server.xml:/usr/local/tomcat/conf/server.xml \
tomcat:8.5.40-jre8

訪問：

http://localhost:8081/auth1/index.html

http://localhost:8081/data1/index.html

http://localhost:8081/code1/index.html

http://localhost:8082/auth/index.html

http://localhost:8082/data/index.html

http://localhost:8082/code/index.html
