【问题描述】:
无法连接到 Tomcat JMX 实例
好的,我现在卡住了 - 我正在尝试使用 Tomcat 配置 JMX,如下所示
$CATALINA_BASE/setenv.sh:
CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=18070 -Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.access.file=$CATALINA_BASE/conf/jmxremote.access"
export CATALINA_OPTS
$CATALINA_BASE/conf/jmxremote.password
monitorRole monitorpass
controlRole controlpass
$CATALINA_BASE/conf/jmxremote.access
monitorRole readonly
controlRole readwrite
我用来访问 Tomcat JMX 服务器的客户端工具与 Tomcat 实例在同一台机器上运行。当我启动 tomcat 时,我可以看到端口 18070 有东西在监听,但是当我尝试连接时,出现以下错误
Exception in thread "main" java.lang.SecurityException: Authentication failed! Credentials required
at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticationFailure(JMXPluggableAuthenticator.java:193)
at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticate(JMXPluggableAuthenticator.java:145)
at sun.management.jmxremote.ConnectorBootstrap$AccessFileCheckerAuthenticator.authenticate(ConnectorBootstrap.java:185)
at javax.management.remote.rmi.RMIServerImpl.doNewClient(RMIServerImpl.java:213)
我使用以下代码进行连接
try {
url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:18070/jmxrmi");
jmxc = JMXConnectorFactory.connect(url,null);
mbsc = jmxc.getMBeanServerConnection();
} catch (MalformedURLException e) {
throw new Exception(methodName + ":" + e);
} catch (IOException e) {
throw new Exception(methodName + ":" + "Failed to connect to the Tomcat Server " + e);
}
如果我将 com.sun.management.jmxremote.authenticate=true 设置为 false,它可以正常工作。除此之外,它只是失败了。客户端工具与 tomcat 实例在同一台机器上运行,因此防火墙应该没有任何问题。任何线索
