Zookeeper错误4_Zookeeper启动时，bin/zkServer.sh: line 109: ./zookeeper.out: Permission denied STARTED错误

启动Zookeeper过程中，一台虚拟机上出现如下的错误：

[[email protected] zookeeper]$ bin/zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... bin/zkServer.sh: line 109: ./zookeeper.out: Permission denied
STARTED
[[email protected] zookeeper]$ 
           

根据字面意思，在对zookeeper.out文件操作时，权限不够，解决方法是增加权限：

[[email protected] hadoop]# cd /usr/local/zookeeper/
[[email protected] zookeeper]# cd bin
[[email protected] bin]# ls
README.txt    zkCli.cmd  zkEnv.cmd  zkServer.cmd  zookeeper.out
zkCleanup.sh  zkCli.sh   zkEnv.sh   zkServer.sh
[[email protected] bin]# chmod a+xwr zookeeper.out 
[[email protected] bin]# ll

[[email protected] bin]# ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[[email protected] bin]
           

在root用户下关闭，返回普通用户下继续启动：

[[email protected] bin]$ ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
           

更改成功。
