来自一枚rookie的项目开发——zookeeper启动失败

[root@VM-0-16-centos bin]# ./zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.8.0/bin/../conf/zoo.cfg
Starting zookeeper ... FAILED TO START

以为是防火墙没开，后面发现是端口2181被占用

[root@VM-0-16-centos ~]# netstat -tunlp|grep 2181
tcp6       0      0 :::2181                 :::*                    LISTEN      1597831/java 

干掉这个占用的进程

[root@VM-0-16-centos ~]# kill 1597831

再次启动Zookeeper

[root@VM-0-16-centos bin]# ./zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.8.0/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

成功
