您应该能够运行zkServer.sh获得群集设置。它会使用相同的conf / zoo.cfg您手动提供，其中将包含集群终端。

来检查你从你的classpath缺少什么（见适当的java命令）***的方法是运行你说你工作的zkServer.sh。

当它启动时，检查用这样的实际命令：

  PS -ef | grep的动物园管理员
 

(I'm running on CentOS 5.8). I've been following the direction for a Clustered (Multiserver) Zookeeper Set-up, but getting an error when I try to start up my server. When I run the command as described in the documentation:

java -cp zookeeper-3.4.6.jar:lib/log4j-1.2.16.jar:conf \ org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo.cfg 

I get the error:

Error: Could not find or load main class  org.apache.zookeeper.server.quorum.QuorumPeerMain

I have my files location as such and am running from the ~/zookeeper-3.4.6 directory:

~/zookeeper-3.4.6/zookeeper-3.4.6.jar 
~/zookeeper-3.4.6/conf/zoo.cfg
~/zookeeper-3.4.6/data/myid
~/zookeeper-3.4.6/lib/log4j-1.2.16.jar
~/zookeeper-3.4.6/bin/zkServer.sh

Does anyone know why this error is happening? I don't quite understand the arguments that are being passed, so it is hard for me to debug the path issue. As a side note, I've tried running ./zookeeper-3.4.6/bin/zkServer.sh start, which did successfully work, but the documentation seems to indicate that command is meant for a single-node instance.

Edit:

I was able to make some progress by modifying the command and taking out the :conf \ part, so now I'm running:

java -cp zookeeper-3.4.6.jar:lib/log4j-1.2.16.jar: org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo.cfg

I get a new error, but this is progress...

which corresponds to lines 63 and 64 from QuorumPeerMain

    private static final Logger LOG = LoggerFactory.getLogger(QuorumPeerMain.class);

You should be able to run zkServer.sh to get a clustered setup. It will use the same conf/zoo.cfg that you are providing manually, which will contain the cluster endpoints.

The best way to check what you are missing from your classpath (and see the proper java command) is to run the zkServer.sh you said worked for you.

When it starts up, check the actual command used like this:

ps -ef | grep zookeeper
