解决Starting zookeeper ... FAILED TO START

今天在启动zookeeper集群时,出现了一个问题—
Starting zookeeper … FAILED TO START

昨天还好好的,今天…
查找原因~
由于提示启动失败,一开始想的就是配置文件的问题,然后去查看配置文件,

tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=5
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=2
dataDir=/usr/local/zookeeper/data
