zookeeper 入坑二： Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to aut
前幾段的時候，Zookeeper的安裝是成功的，也啟動成功，但是今天不知道就怎麼了，另外一臺裝突然就一直啟動不起來。在‘#’後面的是註釋：
# 目前所在的位置：
[[email protected] bin]$ pwd
/home/scidb/zookeeper/zookeeper-3.4.8/bin
# 在bin的檔案下有這些檔案：
[[email protected] bin]$ ls
README.txt zkCli.cmd zkEnv.cmd zkServer.cmd zookeeper.out
zkCleanup.sh zkCli.sh zkEnv.sh zkServer.sh
# 接下來啟動 zkServer.sh
[[email protected] bin]$ sudo sh zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /home/scidb/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
# 看起來是啟動成功了哦，然後我們再來看看是否真的啟動成功了。
[[email protected] bin]$ sh zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/scidb/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
# 呵呵，居然沒有啟動起來。然後我用zkCli.sh 嘗試啟動客戶端，結果。。
