一、概述

方式一、同一个Tomcat 同一个端口部署多个项目

步骤一、默认tomcat支持多应用部署，将多个war包放置在tomcat下的webapps下即可

docker启动

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

步骤二、通过server查看基础配置

<?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>

可以看到监听端口为：8080，部署appBase 为webapps

访问：【这里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

步骤三、自定义虚拟路径

上述访问比较麻烦，规划成如下访问

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>

再次访问上述代码即可。

path属性:指定访问该Web应用的URL入口。如“/auth/”

docBase属性:指定Web应用的文件路径，可以给定绝对路径，可以给定相对路径。。如应用test1的文件路径为<CATALINA_HOME>/webapps/test1

reloadable属性:如果这个属性设为true，tomcat服务器在运行状态下会监视在WEB-INF/classes和WEB-INF/lib目录下class文件的改动，如果监测到有class文件被更新的，服务器会自动重新加载Web应用。

方式二、同一个Tomcat 多个端口部署多个项目

步骤一、$TOMCAT_HOME 路径下新建文件夹webapps1，里面放要发布的项目 .war文件

　　Tomcat默认空间webapps，增加一个项目运行可以新建一个名为webapp-data(或者其他看实际情况)的文件夹，然后加入你要部署的新项目(myProject1)。

步骤二、更改conf中的配置文件：server.xml

新增Service节点

<?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>

步骤三、docker启动

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

访问：

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
