Zookeeper 3.5启动时 8080端口被占用

今天闲来无事,学习Zookeeper,下载了Zookeeper的最新版本3.5。启动以后显示:

ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

以为启动成功,然后连接时报错,查看后台进程,没有Zookeeper进程。

查看zookeeper的日志文件:

2018-06-29 01:36:01,142 [myid:] - ERROR [main:ZooKeeperServerMain@79] - Unable to start AdminServer, exiting abnormally
org.apache.zookeeper.server.admin.AdminServer$AdminServerException: Problem starting AdminServer on address 0.0.0.0, port 8080 and command URL /commands

发现8080端口被占用,通过查阅Zookeeper3.5的官方文档,发现这是Zookeeper3.5的新特性:

这是Zookeeper AdminServer,默认使用8080端口,它的配置属性如下:

我们可以修改在zoo.cfg中修改AdminServer的端口:
admin.serverPort=8888

保存后,再次启动,Zookeeper启动成功。
