#springboot-dubbo

**step1. 单机环境下模拟zookeeper集群

1. download : http://mirrors.hust.edu.cn/apache/zookeeper/
2. 下载zookeeper-3.4.9.tar.gz，并解压
3. 条件有限，打算以区分端口的方式，启动三台zookeeper。

    

- 1.复制一份解压文件到/home/yanshaohui/study/zookeeper/server1/zookeeper-3.4.9
- 2.复制/home/yanshaohui/study/zookeeper/server1/zookeeper-3.4.9/conf/zoo_sample.cfg为zoo.cfg
- 3.编辑zoo.cfg,内容如下：

```
# 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=/home/yanshaohui/zookeeper/server1/data
dataLogDir=/home/yanshaohui/zookeeper/server1/dataLog
# 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=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
```
- server1中创建data和dataLog目录
- 复制serve1两份server2和server3
- 注意后两份中dataDir,dataLogDir分别修改为当前正确的目录
- 后两份中和clientPort依次为2182，2183
- 末尾的server.1...三份一致
- data目录放一个文件，内容只有自己的id，分别为1,2,3

```
echo "1" > /home/yanshaohui/study/zookeeper/server1/data/myid
echo "2" > /home/yanshaohui/study/zookeeper/server2/data/myid
echo "3" > /home/yanshaohui/study/zookeeper/server3/data/myid
```
- 三份的/bin/zkEnv.sh 54行修改日志输出位置，否则会报告权限错误

```
if [ "x${ZOO_LOG_DIR}" = "x" ]
then
    ZOO_LOG_DIR="/home/yanshaohui/study/zookeeper/server1/log"
fi
```



4. 启动三份zookeeper。  
/home/yanshaohui/study/zookeeper/server1/zookeeper-3.4.9/bin/zkServer.sh start
/home/yanshaohui/study/zookeeper/server2/zookeeper-3.4.9/bin/zkServer.sh start
/home/yanshaohui/study/zookeeper/server3/zookeeper-3.4.9/bin/zkServer.sh start

5. jps查看java进程，是否ok
6. netstat -ano | grep 2181 看一下2181端口的情况
7. 看执行状况/home/yanshaohui/study/zookeeper/server3/zookeeper-3.4.9/bin/zkCli.sh
