u盘装系统filemissing-()

zookeeper启动成功，但是使用bin/zkServer.sh status命令显示没有真正运行成功

[root@oraserver apache-zookeeper-3.5.7-bin]# bin/zkServer.sh start/usr/bin/javaZooKeeper JMX enabled by defaultUsing config: /root/data/apache-zookeeper-3.5.7-bin/bin/../conf/zoo.cfgStarting zookeeper ... FAILED TO START

查看日志如下

[root@oraserver apache-zookeeper-3.5.7-bin]# cd logs[root@oraserver logs]# lszookeeper-root-server-oraserver.out[root@oraserver logs]# cat zookeeper-root-server-oraserver.out

根据日志我们可以看出myid文件缺失，应该是myid文件的路径不对，修改zoo.cfg配置文件中的dataDir属性，保证路径正确即可电脑 ，我这里是在zookeeper安装目录中新建了一个data目录存放myid文件，dataDir修改为如下所示。

# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial# synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending a request and getting an acknowledgementsyncLimit=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 connectclientPort=2181server.0=192.168.157.129:2888:3888server.1=192.168.157.130:2888:3888server.2=192.168.157.131:2888:3888

修改完成后便可成功启动。
