求大神告知！！java代码能控制zookeeper停止，不能控制启动

[2014Team]

zookeeper在linux服务器上，我通过java代码来控制启动与停止。
奇怪的是能控制停止，不能控制启动，大神们、高手们指教。
说明:


/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh start

/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh stop

/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh status

我在linux通过执行成功


但是java程序的话
//ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh start");//失败
// ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh satus");//失败
ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh stop");//执行成功

java代码：

package com.common.remote;

import java.io.IOException;


import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public class TestRemoteConnect {

public static void main(String[] args) {

String hostname = "";
String username = "";
String password = "";
//指明连接主机的IP地址
Connection conn = new Connection(hostname);
Session ssh = null;
try {
//连接到主机
conn.connect();
//使用用户名和密码校验
boolean isconn = conn.authenticateWithPassword(username, password);
if (!isconn)
{
System.out.println("用户名称或者是密码不正确");
}
else
{
System.out.println("已经连接OK");
ssh = conn.openSession();
// ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh start");//失败
// ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh satus");//失败
ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh stop");//执行成功
System.out.println("执行ok "+ssh.getExitStatus());

//将Terminal屏幕上的文字全部打印出来
InputStream is = new StreamGobbler(ssh.getStdout());
BufferedReader brs = new BufferedReader(new InputStreamReader(is));
while (true)
{
String line = brs.readLine();
if (line == null)
{
break;
}
System.out.println(line);
}
}

} catch (IOException e)
{
e.printStackTrace();
} finally
{
//连接的Session和Connection对象都需要关闭
ssh.close();
conn.close();
}

}

}

如果停止能成功的话,启动不会不行啊,你最好再用ps -ef|grep zkServer找下你的zkServer进程是否还存在,要不然就用kill的方式直接干掉进程,再启动

我先在linux服务器那边启动 ./zkServer.sh start 执行java程序 ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh stop"); linux 服务器显示停止 再 ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh start"); 查看linux服务器依然还是停止状态 说明，java代码启动之前我在服务器端执行 ./zkServer.sh stop了也检查了zookeeper进程确实被kill掉了， 但是java代码就是起不来

第一步： [comp@sv0325 bin]$ ./zkServer.sh start JMX enabled by default Using config: /opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/../conf/zoo.cfg Starting zookeeper ... STARTED [comp@sv0325 bin]$ ./zkServer.sh status JMX enabled by default Using config: /opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/../conf/zoo.cfg Mode: standalone [comp@sv0325 bin]$ 第二步： 执行java代码 ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh stop"); 停止成功 第三步： [comp@sv0325 bin]$ ./zkServer.sh status JMX enabled by default Using config: /opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/../conf/zoo.cfg Error contacting service. It is probably not running. [comp@sv0325 bin]$ ps -ef|grep zookeeper-3.4.6 comp 29674 29333 0 11:24 pts/3 00:00:00 grep zookeeper-3.4.6 [comp@sv0325 bin]$ 第四步： 执行java代码启动 ssh.execCommand("/opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/zkServer.sh start"); 第五步 [comp@sv0325 bin]$ ./zkServer.sh status JMX enabled by default Using config: /opt/aspire/product/comp/program/soft/zookeeper-3.4.6/bin/../conf/zoo.cfg Error contacting service. It is probably not running. [comp@sv0325 bin]$ ps -ef|grep zookeeper-3.4.6 comp 29769 29333 0 11:25 pts/3 00:00:00 grep zookeeper-3.4.6 [comp@sv0325 bin]$ 启动失败

之前看过一文 http://www.csdn.net/article/2015-06-02/2824824 认识到其强大之处~

启动失败zk会有失败日志的,你看看日志输出什么

终于研究出来了，尝试来了很多结果。最后在zkServer.sh文件加入 JAVA_HOME=/usr/local/java/jdk1.7.0_76 PATH=$JAVA_HOME/bin:$PATH CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME export PATH export CLASSPATH 搞定！ 非常感谢大家的帮助，谢谢！！
