zookeeper linux下无法启动的问题

在linux下安装zookeeper时，出现了如下的错误：

 

 

 [hadoop @hadoop -master bin]$ ./zkServer.sh start
 JMX disabled by user request
 Using config: /opt/zookeeper-3.3 . 3 /bin/../conf/zoo.cfg
 Starting zookeeper ...

 [hadoop@hadoop -master bin]$  2011 - 07 - 05   10 : 33 : 57 , 587  - INFO  [main:QuorumPeerConfig @90 ] - Reading configuration from: /opt/zookeeper- 3.3 . 3 /bin/../conf/zoo.cfg

    at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:76 )

 

 发现没有找到java.lang.management下的一个方法。如果使用的是标准的JDK的话，不应该出现这样的错误的。于是查看zkServer.sh的脚本。发现启动java程序的脚本如下：

 

 java   "-Dzookeeper.log.dir=${ZOO_LOG_DIR}"   "-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}"  \
     -cp "$CLASSPATH"  $JVMFLAGS $ZOOMAIN  "$ZOOCFG"  &

 

 在linux下直接执行java命令，发现输出如下：

 

 [hadoop@hadoop-master bin]$ java
 Usage: gij [OPTION] ... CLASS [ARGS] ...
           to invoke CLASS.main, or
        gij -jar [OPTION] ... JARFILE [ARGS] ...
           to execute a jar file
 Try `gij --help' for more information.

 

 显然，zkServer.sh使用的java不正确。使用的gij的java。解决这个问题就简单了，把脚本改成：

 

 $JAVA_HOME/bin/java   "-Dzookeeper.log.dir=${ZOO_LOG_DIR}"   "-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}"  \
    -cp "$CLASSPATH"  $JVMFLAGS $ZOOMAIN  "$ZOOCFG"  &

 

这样修改之后，就能正常运行了。
