zookeeper3.5后启动报端口被占
这是Zookeeper AdminServer,默认使用8080端口
需要在zoo.cfg 里设置admin.serverPort=8888

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:
1 2 3 |
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:
1 2 |
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:
1 |
admin.serverPort= 8888
|
保存后,再次启动,Zookeeper启动成功。
