zookeeper日誌顯示myid file is missing

zookeeper啟動成功，但是使用bin/zkServer.sh status命令顯示沒有真正運行成功

<code>[root@oraserver apache-zookeeper-3.5.7-bin]# bin/zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /root/data/apache-zookeeper-3.5.7-bin/bin/../conf/zoo.cfg
Starting zookeeper ... FAILED TO START

<code>[root@localhost apache-zookeeper-3.5.7-bin]# bin/zkServer.sh status

Client port found: 2181. Client address: localhost.
Error contacting service. It is probably not running.

查看日誌如下

<code>[root@oraserver apache-zookeeper-3.5.7-bin]# cd logs
[root@oraserver logs]# ls
zookeeper-root-server-oraserver.out
[root@oraserver logs]# cat zookeeper-root-server-oraserver.out

根據日誌我們可以看出myid文件缺失，應該是myid文件的路徑不對，修改zoo.cfg配置文件中的dataDir屬性，保證路徑正確即可，我這裡是在zookeeper安裝目錄中新建了一個data目錄存放myid文件，dataDir修改為如下所示。

<code># The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/root/data/apache-zookeeper-3.5.7-bin/data
# the port at which the clients will connect
clientPort=2181
server.0=192.168.157.129:2888:3888
server.1=192.168.157.130:2888:3888
server.2=192.168.157.131:2888:3888
/<code>

修改完成後便可成功啟動。

<code>[root@oraserver apache-zookeeper-3.5.7-bin]# bin/zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /root/data/apache-zookeeper-3.5.7-bin/bin/../conf/zoo.cfg
