1 ）四字命令

在  Zookeeper  服务器成功启动的前提下，在  Linux  侧的  shell  命令端口执行下面的  ruok  四字命令， 如果能够显示

imok ，表示  zk  服务器端成功启动。

使用四字命令：

echo ruok | nc 127.0.0.1 2181

启动报错误：

[root@Hadoop ~]# zook
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    [root@Hadoop ~]#  cd   /opt/modules/zookeeper-3.4.5/bin
    [root@Hadoop bin]# ./zkServer.sh  status
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Error contacting service. It is probably not running.
    [root@Hadoop bin]#

解决办法 ：

\[root@Hadoop bin\]\# cd  ../zkData/  
\[root@Hadoop zkData\]\# ls  
my.id  zookeeper\_server.pid  
\[root@Hadoop zkData\]\# cat  my.id

1  
\[root@Hadoop zkData\]\# vi  my.id   
\[root@Hadoop zkData\]\# cd  ./bin  
\-bash: cd: ./bin: No such file or directory  
\[root@Hadoop zkData\]\# cd  ..  
\[root@Hadoop zookeeper-3.4.5\]\# cd  bin  
\[root@Hadoop bin\]\# ./zkServer.sh  stop  
JMX enabled by default  
Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg  
Stopping zookeeper ... ./zkServer.sh: line 143: kill: (2605) - No such process  
STOPPED  
\[root@Hadoop zkData\]\# ls  
my.id  zookeeper\_server.pid  
\[root@Hadoop zkData\]\# rm  -rf zookeeper\_server.pid   
\[root@Hadoop zkData\]\# cat  my.id   
1  
\[root@Hadoop zkData\]\# cd ../bin  
\[root@Hadoop bin\]\# ./zkServer.sh start  
JMX enabled by default  
Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg  
Starting zookeeper ... STARTED  
\[root@Hadoop bin\]\# ./zkServer.sh status  
主要需要查询日志然后才可以进行启动哦：

操作步骤在bin的下面查询。out日志

[root@Hadoop zkData]# cd ../bin
    [root@Hadoop bin]# ./zkServer.sh start
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    [root@Hadoop bin]# ./zkServer.sh status
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Error contacting service. It is probably not running.
    [root@Hadoop bin]# ls
    README.txt  zkCleanup.sh  zkCli.cmd  zkCli.sh  zkEnv.cmd  zkEnv.sh  zkServer.cmd  zkServer.sh  zookeeper.out
    [root@Hadoop bin]# tail  -f  zookeeper.out 
    2020-02-28 23:04:41,337 [myid:] - ERROR [main:QuorumPeerMain@85] - Invalid config, exiting abnormally

    ^C
    [root@Hadoop bin]# cd  ../zkData/
    [root@Hadoop zkData]# ls
    my.id  zookeeper_server.pid
    [root@Hadoop zkData]# mv  my.id myid
    [root@Hadoop zkData]# ls
    myid  zookeeper_server.pid
    [root@Hadoop zkData]# zook
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    [root@Hadoop zkData]#

然后查询状态，就是启动正常：

[root@Hadoop ~]#   cd  /opt/modules/zookeeper-3.4.5/bin
    [root@Hadoop bin]# ./zkServer.sh  status
    JMX enabled by default
    Using config: /opt/modules/zookeeper-3.4.5/bin/../conf/zoo.cfg
    Mode: follower
    [root@Hadoop bin]#
