查看日志的时候：
虽然~就是/root，但是如下是不可以的
java -cp :~/apache-zookeeper-3.6.0-bin/lib/slf4j-api-1.7.25.jar:~/apache-zookeeper-3.6.0-bin/lib/zookeeper-3.6.0.jar:~/apache-zookeeper-3.6.0-bin/lib/zookeeper-jute-3.6.0.jar org.apache.zookeeper.server.LogFormatter log.200000001
正确的应该是
java -cp :/root/apache-zookeeper-3.6.0-bin/lib/slf4j-api-1.7.25.jar:/root/apache-zookeeper-3.6.0-bin/lib/zookeeper-3.6.0.jar:/root/apache-zookeeper-3.6.0-bin/lib/zookeeper-jute-3.6.0.jar org.apache.zookeeper.server.LogFormatter log.200000001
