Tomcat：将端口从8080更改为80不起作用

标签： java linux tomcat digital-ocean vps

我有一个运行在DigitalOcean VPS上的tomcat服务器。 server.xml文件如下所示：

<?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="8080" 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>
    </Engine>
  </Service>
</Server>

我编辑了<Connector>部分，以使服务器在端口80而不是8080上运行。在进行更改之前，我可以使用IP:8080地址访问服务器，但是现在我根本无法访问它-无论使用IP:8080还是IP:80或IP。 我使用shutdown.sh和startup.sh重新启动了tomcat，并使用sudo reboot重新启动了我的小滴，但是它什么也没改变。

我使用sudo ufw status verbose检查了防火墙，它的状态为inactive。

编辑：

我再次尝试了shutdown.sh-> startup.sh-> sudo reboot路线，这是自catalina.out命令以来的shutdown.sh：

端口号1至1023保留供系统使用，可能是因为您无法将端口号更改为80。

答案 1 :(得分：0)

在@ernest_k的帮助下，我设法找到了问题。问题在于端口从未真正从8080更改为80。发生这种情况是因为尽管我以root用户身份连接到VPS，但由于tomcat文件的存在，tomcat自动切换到非root用户/etc/systemd/system/tomcat.service：

[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

所以我将User=tomcat更改为User=root，重新启动了一切，现在一切正常！
