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:

admin.serverPort= 8888 |
保存后,再次启动,Zookeeper启动成功。
