关于zookeeper启动的问题

[Java_er]

启动不报错：

[root@redis bin]# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@redis bin]# 

查看状态：

[root@redis bin]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.8/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
[root@redis bin]# 

1、端口没有被占用
2、JDK环境变量正确

[root@redis bin]# echo $JAVA_HOME
/usr/java/jdk1.6.0_45
[root@redis bin]# echo $CLASSPATH
.:/usr/java/jdk1.6.0_45/lib/dt.jar:/usr/java/jdk1.6.0_45/lib/tools.jar
[root@redis bin]# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
[root@redis bin]# 

[root@redis bin]# whereis java
java: /usr/bin/java
[root@redis bin]# which java
/usr/java/jdk1.6.0_45/bin/java
[root@redis bin]# 

查看日志是类没招到，网上搜了一圈。。也没招到解决的办法

[root@redis bin]# vim zookeeper.out

你只是单纯的启动zookeeper么？

引用 1 楼 fengspg 的回复:

http://zookeeper.apache.org/doc/r3.3.3/zookeeperAdmin.html#sc_zkMulitServerSetup 集群环境，貌似要加编译环境。 If your configuration file is set up, you can start a ZooKeeper server: $ java -cp zookeeper.jar:lib/log4j-1.2.15.jar:conf \ org.apache.zookeeper.server.quorum.QuorumPeerMain zoo.cfg QuorumPeerMain starts a ZooKeeper server, JMX management beans are also registered which allows management through a JMX management console. The ZooKeeper JMX document contains details on managing ZooKeeper with JMX. See the script bin/zkServer.sh, which is included in the release, for an example of starting server instances.

应该是myid没有配置，在配置的zookeeper数据文件路径下创建一个myid文件，写入设置的数字
