zookeeper学习笔记001-Address already in use: bind启动报错

JAVA技术交流QQ群：170933152 

第一次安装,填坑的时候

异常由于我本地8080端口占用:

查看端口占用可以用下面的命令:

windows cmd中:

netstat -ano|findstr "2181" 我一查这个端口没有被占用啊

C:\Users\Administrator>netstat -ano|findstr "2181"

郁闷,之后才知道,这货,原来用jetty服务器,占用的是8080端口,查了一下:

通过查看zookeeper的官方文档，发现有3种解决途径：

（1）.删除jetty。

（2）修改端口。

修改方法的方法有两种，一种是在启动脚本中增加 -Dzookeeper.admin.serverPort=你的端口号.一种是在zoo.cfg中增加admin.serverPort=没有被占用的端口号。

（3）停用这个服务，在启动脚本中增加"-Dzookeeper.admin.enableServer=false"。

我用第二种方法修改:

我修改后的配置文件:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
#initLimit=5  
#syncLimit=2  
#server.1=192.168.211.1:2888:3888  
#server.2=192.168.211.2:2888:3888
admin.serverPort=8089 //这里添加了设置了jetty服务器启动的时候的端口

这样就好了,下面是异常信息
