我尝试将应用程序部署到tomcat7服务器时出错

Question

我正在尝试通过eclipse luna将web应用程序部署到tomcat7，但是我收到此错误：

Uploading: http://localhost:8080/manager/text/deploy?path=%2Floja

我也尝试部署到tomcat8，但我得到同样的错误。

在我的pom.xml中，我有与此操作相关的配置：

  <build>
    <finalName>loja</finalName>
    <plugins>
        <plugin>
           <groupId>org.apache.tomcat.maven</groupId>

            </configuration>
        </plugin>
    </plugins>
</build>

谁知道这里发生了什么？

UPDATE

我尝试使用命令mvn:tomcat7 deploy -X部署应用程序，输出是：

好吧，我和tomcat7有同样的问题。

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset
[INFO] Retrying request
Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset
[INFO] Retrying request
Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover

[INFO] I/O exception (java.net.SocketException) caught when processing request:         Connection reset
[INFO] Retrying request
Uploading: http://localhost:8080/manager/text/deploy?path=%2iplover

我无法使用它

mvn tomcat7:redeploy 

正如提到的here。

我的WAR不是很大，只有4MB。

这是根本问题和解决方案

您的tomcat-users.xml具有正确的角色设置非常重要。我只有manager设置的角色。添加manager-script似乎很重要，完全解决了我的问题。

<role rolename="manager"/>
<role rolename="manager-script"/>
<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager,manager-gui,manager-script"/>

Answer 2

就我的AWS amazon实例而言，原因是：

在我的EC2现场实例上，磁盘空间已经完全注意到了99％

我正常使用这个命令使用jenkins

 mvn clean tomcat7:redeploy -Ddeploy.password=xxxAG1
 -Ddeploy.username=admin -Ddeploy.context=/v1 -Ddeploy.url=http://localhost:8080/manager/text

只是释放那个空间，它与我合作。

我遇到的错误是

[INFO] I/O exception (java.net.SocketException) caught when processing request: Connection reset
[INFO] Retrying request

提示使用此命令来追踪从（command is from stackoverflow）sudo du -x -d1 -h /你的空间吃什么

Answer 3

（重新）使用Maven tomcat插件进行部署也失败了，客户端上的连接重置和Tomcat 8.5.30上的localhost_access.log中的403状态代码也失败了。

这个Tomcat版本的管理器应用程序默认配置了RemoteAddrValve，限制了对localhost的/ manager / *路径的访问。见$TOMCAT_HOME/webapps/manager/META-INF/context.xml。

它帮助turn on the logging找到the solution to this。

Answer 4

我不知道是否有人解决了这个问题。我在我的案例中找到了一种解决方法：使用redeploy而不是部署工作正常。

问题可能与内存问题或读/写访问有关吗？

Answer 5

你的战争规模是多少？也许是因为尺寸太大了。默认情况下，tomcat管理器只允许小于50MB的大小战争。也尝试mvn tomcat7：重新部署而不是部署。

See here how to increase the war size limit

Answer 6

默认情况下，Tomcat的最大上载大小为50MB。 （即最大尺寸的WAR文件）

如果您需要更大的文件，请尝试在tomcat max-file-size中增加max-request-size和web.xml。注意：这些值都以字节存储。

编辑.../webapps/manager/WEB-INF/web.xml。 （确保文件大小大于您尝试上传的war文件）。即如果你需要80MB WAR，

  <max-file-size>82914560</max-file-size>
  <max-request-size>82914560</max-request-size>

然后重启apache tomcat。

Answer 7

我遇到了同样的问题，并通过运行maven目标解决了这个问题

tomcat7：重新部署

代替

tomcat7：部署

它适用于tomcat7和tomcat8，我的war文件总是低于50mb。

Answer 8

检查〜/ .m2 / settings.xml

<settings>
  <servers>
    <server>
      <id>tomcat-manager</id>
      <username>user001</username>
      <password>123</password>
    </server>
  </servers>
</settings>

Answer 9

我遇到了同样的问题，在我的情况下，问题是一个不以/开头的cunfigured上下文路径。将上下文路径“myapp”修复为“/ myapp”解决了这个问题。

Answer 10

偶尔出问题

如果有时重新部署失败，有时会成功，增加日志记录可能会显示DOS保护。

编辑/conf/logging.properties并添加该行

org.apache.catalina.level = FINEST

在文件的末尾。可能会显示此输出：

FINE [http-nio-8080-exec-7] org.apache.catalina.core.ApplicationDispatcher.doForward  Disabling the response for further output

（在此日志记录中，尝试上载的用户具有用户名admin）

正如您在此输出中看到的，用户admin已被锁定：

WARNING [http-nio-8080-exec-7] org.apache.catalina.realm.LockOutRealm.filterLockedAccounts 
  An attempt was made to authenticate the locked user [admin]

看看documentation和server.xml内部你会发现一个

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

使用不可预见的用户名

删除该行是一个坏主意，将重新部署的用户名更改为另一个更不可预见的名称，如deploy355547511，以便不被锁定。

Answer 11

我不知道这是否有帮助，但在我的情况下。 tomcat7插件从maven conf settings.xml中选择服务器详细信息，而不是从.m2 \ settings.xml。在该文件中添加服务器信息已解决我的问题。
