在阿里云上搭建Zookeeper时，利用bin/zkServer.sh start启动Zookeeper出现如下错误：
$ bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/lmg/Softwares/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... bin/zkServer.sh: line 149: zookeeper/zkData/zookeeper_server.pid: Permission denied
FAILED TO WRITE PID
$ bin/zkServer.sh: line 140: ./zookeeper.out: Permission denied

使用命令：sudo chown -R xxx:xxx zookeeper/
问题解决：
$ bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/lmg/Softwares/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
