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：

-master bin]$ ./zkServer.sh start

 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。
