记录一个启动zookeeper的坑

启动
dell@dell-Precision-7920-Tower:/etc$ zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/dell/Downloads/zookeeper-3.4.9/bin/../conf/zoo.cfg Starting zookeeper ... /home/dell/Downloads/zookeeper-3.4.9/bin/zkServer.sh: line 140: ./zookeeper.out: Permission denied STARTED

好像是权限不够

dell@dell-Precision-7920-Tower:/etc $zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/dell/Downloads/zookeeper-3.4.9/bin/../conf/zoo.cfg Error contacting service. It is probably not running. dell@dell-Precision-7920-Tower:/etc$

用su开权限，又出问题了：su: Authentication failure,用sudo passwd root命令设置新密码解决了，但成功用su开启root环境后使用zkServer.sh start命令又出问题了： zkServer.sh: command not found

找到问题了！！！！ 是bin目录权限有问题，导致无法写入， 使用sudo chmod 777 .../bin命令对其进行解锁，成功！

又出现问题了：

查看.out文件，破案：是java环境没配置，装好java环境后成功：
