的Tomcat 7無法啓動由於沒有jmxremote.access文件，而JMX認證功能

Question

我的Tomcat 7（亞馬遜歐盟主辦，JAVA 1.7.0_51）無法啓動，以下情況例外：

JMX啓用，因爲我在/usr/share/tomcat7/conf/tomcat7.conf以下行：

$CATALINA_OPTS=-Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=ec2-<ip>.eu-west-1.compute.amazonaws.com -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false 

和/usr/share/tomcat7/conf/server.xml下列之一：

<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" 
      rmiRegistryPortPlatform="9998" rmiServerPortPlatform="9998"/> 

如果我評論這兩行，一切都很好。

問題是：爲什麼jmxremote.access在「authenticate」設置爲false時是必需的。

Answer 1

你是對的，如果你設置了com.sun.management.jmxremote.authenticate=false你不應該需要jmxremote.access文件，我相信問題是JMX參數沒有被tomcat拾起，因爲我知道，tomcat7.conf不是爲Tomcat標準配置文件（check this），嘗試加入他們，而不是到/usr/share/tomcat7/bin/catalina.sh，像這樣的：如何配置Tomcat check this

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=ec2-<ip>.eu-west-1.compute.amazonaws.com -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false" 

脫穎而出更多的信息，你會看到在catalina.sh頭些文檔。

Answer 2

嘗試在雙引號包圍的命令行參數，例如：

$CATALINA_OPTS="-Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=ec2-<ip>.eu-west-1.compute.amazonaws.com -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false" 

我的猜測是，它只有在拍攝第一放慢參數進去，因爲缺少引號。
