dubbo+zookeeper对8080端口的占用问题
作者：互联网
dubbo的注册中心和zookeeper里都有jetty的成分，jetty的默认端口又是8080，当二者与springboot进行整合时，springboot内置的tomcat的端口8080就会被jetty占用。
如果尝试使用命令来杀死8080所在进程，那杀死的八成是zookeeper的服务。
为了解决jetty的问题需要同时对dubbo注册中心和zookeeper的配置文件同时进行更改。
首先说dubbo的注册中心路径：
dubbo-admin\incubator-dubbo-ops-master\dubbo-monitor-simple
通过使用dubbo注册中心的常规操作，来看一下注册中心里的jetty是怎么占用端口号，从最开始使用注册中心说起：
需要来到dubbo-monitor-simple文件夹下，接着cmd进入命令模式：
这时会生成target文件夹
打开target
解压dubbo-monitor-simple-2.0.0的压缩包产生dubbo-monitor-simple-2.0.0，
之后复制dubbo-monitor-simple-2.0.0到incubator-dubbo-ops-master文件夹下
打开dubbo-monitor-simple-2.0.0，找到conf配置文件，修改jetty服务器的端口号为8081，如下：
这样做是为了避免当注册中心启动jetty服务器时与tomcat8080端口冲突。
接下来修改zookeeper，知道它占用了8080端口号，因为我提供服务的应用点击运行总是被提示这样的信息：
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

而我每次用命令先查看8080的进程
接着杀死进程
可是每次关闭进程，zookeeper的服务也被关闭了，不知道为什么会这样，一开始我想zookeeper没有道理占用8080端口。
一想到8080端口，我又想起一件怪事，就是之前dubbo里监控台所用的jetty端口号被改成8081，可以访问。这就是奇怪的地方，分明端口号已经不再是8080，却显示jetty在占用8080。
如图jetty可以在8081访问：
可是同时这里又显示8080被jetty所占用，那这个jetty是怎么回事儿？
于是查了百度，有人给出了答案，就是zookeeper里从新版本开始内置了jetty，所以是zookeeper里还有jetty在占用8080端口。
解决方法，修改zookeeper的配置文件zoo.cfg：
添加一条配置信息：admin.serverPort=8080
修改之后看看效果：
首先关闭之前的zookeeper服务，就是关闭终端，之后通过命令重新启动zkServer.cmd
再次访问8080端口：
很好，无法访问说明zookeeper里的jetty不再占用8080端口号了，暗自佩服zookeer里jettty隐藏的好深、毫无征兆，看来一切都因为自己安装最新版的zookeeper惹的祸。
那我的提供者是否恢复、可以通过tomcat的8080端口启动了呢？
如图，启动提供者应用后，访问监控中心显示已经有提供者了，恢复了正常。
就这样吧，虽然花了点时间，但是还是有所收获>>>
