Zookeeper集群脚本启动问题

问题：

运行：./start.sh看见启动成功了，有输出。但是输入jps查看的时候，会发现没有QuorumPeerMain 进程。说明没有启动成功

分析原因

首先知道交互式shell和非交互式shell、登录shell和非登录shell是有区别的
在登录shell里，环境信息需要读取/etc/profile和~ /.bash_profile, ~/.bash_login, and ~/.profile按顺序最先的一个，并执行其中的命令。除非被 —noprofile选项禁止了；在非登录shell里，环境信息只读取 /etc/bash.bashrc和~/.bashrc 
手工执行是属于登陆shell，脚本执行数据非登陆shell，而我的linux环境配置中只对/etc/profile进行了jdk1.8等环境的配
置，所以脚本执行/opt/module/zookeeper-3.4.10/bin/zkServer.sh start 启动zookeeper失败了

解决方法

把profile的配置信息echo到.bashrc中  cat  /etc/profile  >> ~/.bashrc
在/zookeeper/bin/zkEnv.sh的中开始位置添加export JAVA_HOME=/opt/module/jdk1.8.0_191

 附带脚本

#!/bin/bash
