使用ll命令和chown命令对zookeeper文件的拥有者进行修改后，在普通用户hadoop下启动zookeeper，但是报一下错误：

[hadoop@Slave1 zookeeper]$ bin/zkServer.sh startJMX enabled by defaultUsing config: /usr/local/zookeeper/bin/../conf/zoo.cfgStarting zookeeper ... bin/zkServer.sh: line 113: /usr/local/zookeeper/zkdata/zookeeper_server.pid: Permission deniedFAILED TO WRITE PID[hadoop@Slave1 zookeeper]$

主要错误点是：Permission denied FAILED TO WRITE PID，字面意思是没有写权限。

接下来，使用chmod命令增加权限，再次启动，成功：

[hadoop@Slave1 local]$ suPassword: [root@Slave1 local]# chmod a+xwr zookeeper/[root@Slave1 local]# exitexit[hadoop@Slave1 local]$ cd zookeeper/[hadoop@Slave1 zookeeper]$ bin/zkServer.sh startJMX enabled by defaultUsing config: /usr/local/zookeeper/bin/../conf/zoo.cfgStarting zookeeper ... STARTED[hadoop@Slave1 zookeeper]$
