1 首先安装Zookpeer
[root@bogon tmp]# ls apache-zookeeper-3.7.0-bin.tar.gz jdk1.8.0_141 jdk8.tar.gz [root@bogon tmp]# tar -zxvf apache-zookeeper-3.7.0-bin.tar.gz [root@bogon tmp]# tar -zxvf jdk8.tar.gz [root@bogon tmp]# mv jdk1.8.0_141/ /usr/local/ [root@bogon tmp]# mv apache-zookeeper-3.7.0-bin/ /usr/local/zookpeer [root@bogon tmp]# cd /usr/local/ [root@bogon local]# ls bin etc games include jdk1.8.0_141 lib lib64 libexec sbin share src zookeeper [root@bogon local]# vim /etc/profile # --------写入文件------------ export JAVA_HOME=/usr/local/jdk1.8.0_141 export JER_HOME=${JAVA_HOME}/jre export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin export PATH=$PATH:${JAVA_PATH} # --------写入文件完成------------ [root@bogon local]# source /etc/profile [root@bogon local]# java -version java version "1.8.0_141" Java(TM) SE Runtime Environment (build 1.8.0_141-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode) [root@bogon local]# cd zookeeper/ [root@bogon conf]# cp zoo_sample.cfg zoo.cfg [root@bogon conf]# cd ../bin [root@bogon bin]# ./zkServer.sh start [root@bogon bin]# ./zkServer.sh start ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Starting zookeeper ... STARTED [root@bogon bin]# ./zkCli.sh Connecting to localhost:2181 ...... [zk: localhost:2181(CONNECTED) 1] ls / [zookeeper] 复制代码
zookpeer的启动和重启命令：
[root@bogon bin]# ./zkServer.sh start //启动 [root@bogon bin]# ./zkServer.sh stop //停止 [root@bogon bin]# ./zkServer.sh status //查看当前状态 [root@bogon bin]# ./zkServer.sh restart //重启 [root@bogon bin]# ./zkServer.sh version //查看当前版本 复制代码

2.4 启动后观察Zookpeer并测试
doubbo_interface不需要启动，只需要install就可以了
[zk: localhost:2181(CONNECTED) 14] ls / [dubbo, zookeeper] [zk: localhost:2181(CONNECTED) 15] ls /dubbo [org.ymx.doubbo_consumer.service.UserService, org.ymx.doubbo_provider.service.UserService] 复制代码
