zookeeper的安装及zookeeper集群的搭建

Window
1.将zookeeper的安装包解压(具体路径,自己定)

2.进去解压后的conf目录将zoo_sample.cfg复制到当前路径并改名为zoo.cfg(因为系统默认寻找
zoo.cfg)

3.实现dubbo-admin的访问:
>将dubbo-admin-2.5.4.war的war包放入tomcat安装路径下的webapps目录然

>先开启zookeeper,cmd命令提示符,进入zookeeper的安装路径进入zookeeper下的bin目录

>命令:zkServer.cmd 开启zookeeper

>然后开启tomcat 在tomcat安装路径下的bin目录下点击startup.bat 开启tomcat
tomcat会自动将你放在webapps下的dubbo-admin-2.5.4的war 包进行解压.

>访问http://localhost:8080/dubbo-admin-2.5.4 就进入了dubbo-admin的界面

注:账户密码在tomcat中的dubbo-admin-2.5.4.war的war包解压之后的dubbo-admin-2.5.4中的WEB-
INF下的dubbo-properties中查看可配置

Linux
1.下载zookeeper的安装包将其放到Linux系统中
2.解压安装包进入zookeeper-3.4.9目录
3.然后进入bin目录
4.进去zookeeper 开启zookeeper 命令:sh zkServer.sh start ../conf/zoo_sample.cfg
5.然后进行测试 netstat -na|grep 2181

开启zookeeper:sh zkServer.sh start ../conf/zoo_sample.cfg

测试zookeeper是否安装成功:netstat -tulnp|grep 2181

测试自己是否可以连上别人的zookeeper : sh zkCli.sh -server 192.168.1.100

Linux中zookeeper集群的搭
第一步：解压zookeeper，tar -zxvf zookeeper-3.4.6.tar.gz将zookeeper-3.4.6拷贝
到/usr/local/solrcloud下(自己创建该文件夹)，复制三份分别并将目录名改为zookeeper1、
zookeeper2、zookeeper3
第二步：进入zookeeper1文件夹，创建data目录。并在data目录中创建一个myid文件内容
为“1”（echo 1 >> data/myid）。
第三步：进入conf文件夹，把zoo_sample.cfg改名为zoo.cfg
第四步：修改zoo.cfg。
修改：
dataDir=/usr/local/solrcloud/zookeeper1/data
clientPort=2181（zookeeper2中为2182、zookeeper3中为2183）
在文件末端添加：
server.1=192.168.25.150:2881:3881
server.2=192.168.25.150:2882:3882
server.3=192.168.25.150:2883:3883

# 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=/usr/local/solrcloud/zookeeper1/data
# 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
server.1=192.168.25.150:2881:3881
server.2=192.168.25.150:2882:3882
server.3=192.168.25.150:2883:3883

第五步：对zookeeper2、3中的设置做第二步至第四步修改。
zookeeper2：
myid内容为2
dataDir=/usr/local/solrcloud/zookeeper2/data
clientPort=2182
Zookeeper3：
的myid内容为3
dataDir=/usr/local/solrcloud/zookeeper3/data
clientPort=2183
第六步：启动三个zookeeper
/usr/local/solrcloud/zookeeper1/bin/zkServer.sh start
/usr/local/solrcloud/zookeeper2/bin/zkServer.sh start
/usr/local/solrcloud/zookeeper3/bin/zkServer.sh start
查看集群状态：
/usr/local/solrcloud/zookeeper1/bin/zkServer.sh status
/usr/local/solrcloud/zookeeper2/bin/zkServer.sh status
/usr/local/solrcloud/zookeeper3/bin/zkServer.sh status

第七步：开启zookeeper用到的端口，或者直接关闭防火墙。
service iptables stop
