DigitalOcean VPS Tomcat 服务器：无法配置端口 80 和多个域名

我在 DigitalOcean 上有一个 VPS（droplet），我正在尝试为我的服务器配置 80 端口和几个域名。

阅读了一些问题和答案后，我像这样编辑了我的 server.xml 文件：

<?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.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="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <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>

      <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>

      <Host name="codingrecords.tk"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

         <Alias>www.codingrecords.tk</Alias>


        <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 path="" docBase="/opt/tomcat/webapps/Test"
    debug="0" reloadable="true"/>

      </Host>


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

也就是说，我更改了端口<Connector>并添加了一个额外的<Host>块。但是现在我不仅无法通过IP、IP:80、访问该文件IP:8080，也无法使用codingrecords.tk域名访问它。域名有两个 A 记录指向我的 droplet 的 IP 地址。

想办法。

首先我需要更改/etc/systemd/system/tomcat.service文件：

[Unit]
Description=Apache Tomcat Web Application Container
After=network.target

[Service]
Type=forking

Environment=JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64/jre
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh

User=tomcat
Group=tomcat
UMask=0007
RestartSec=10
Restart=always

[Install]
WantedBy=multi-user.target

我将 改为User=tomcat，User=root因为否则 Tomcat 会自动使用非 root 用户，并且端口绑定会失败。 看起来不错！
