写了shell脚本想一键启动三台虚拟机的Zookeeper，却不知道为啥总是启动不了

首先，一键启动的shell脚本是这样的

#! /bin/bash

case $1 in
"start"){
        for i in node01 node02 node03
        do
                ssh $i "/opt/module/zookeeper-3.4.5-cdh5.14.0/bin/zkServer.sh start"
        done
        };;
"stop"){
        for i in node01 node02 node03
        do
                ssh $i "/opt/module/zookeeper-3.4.5-cdh5.14.0/bin/zkServer.sh stop"
        done
        };;
esac

然后，zk.sh start启动，发现只有

[root@node01 ~]# zk.sh start
JMX enabled by default
Using config: /opt/module/zookeeper-3.4.5-cdh5.14.0/bin/…/conf/zoo.cfg
Starting zookeeper … STARTED
JMX enabled by default
Using config: /opt/module/zookeeper-3.4.5-cdh5.14.0/bin/…/conf/zoo.cfg
Starting zookeeper … STARTED
JMX enabled by default
Using config: /opt/module/zookeeper-3.4.5-cdh5.14.0/bin/…/conf/zoo.cfg
Starting zookeeper … STARTED

是显示启动了，但是jps一查看啥也没有，最骚的是，它stop的命令可以执行…

经过一天的各种谷歌…首先，我找到三篇宝藏
https://scottlinux.com/2012/03/07/troubleshooting-ssh-server-logs-and-error-messages/
https://www.centos.bz/2017/08/ssh-connect-failed-solve-experience/
https://note.t4x.org/other/didnot-receive-identification-string-from/
但是对我完成并没啥用，最后阴差阳错拿到了一个办法…竟然有用
三台虚拟机都执行以下

cat /etc/profile >> ~/.bashrc

记得看一下有没有把配置环境变量的加到里面

vim ~./bashrc
