zookeeper伪集群
Zookeeper运行需要java环境，需要安装jdk，建议本地下载好需要的安装包然后上传到服务器上面，服务器上面下载速度太慢。

| 参数 | 说明 |
|---|---|
tickTime=2000 |
这个时间是作为zookeeper服务器之间或客户端与服务器之间维持心跳的时间间隔,也就是说每个tickTime时间就会发送一个心跳 |
initLimit=10 |
这个配置项是用来配置zookeeper接受客户端（这里所说的客户端不是用户连接zookeeper服务器的客户端,而是zookeeper服务器集群中连接到leader的follower服务器）初始化连接时最长能忍受多少个心跳时间间隔数。当已经超过 10个心跳的时间（也就是tickTime）长度后 zookeeper 服务器还没有收到客户端的返回信息,那么表明这个客户端连接失败。总的时间长度就是 10*2000=20秒 |
syncLimit=5 |
这个配置项标识leader与follower之间发送消息,请求和应答时间长度,最长不能超过多少个tickTime的时间长度,总的时间长度就是5*2000=10秒 |
dataDir=/opt/soft/zookeeper1/data |
zookeeper保存数据的目录,默认情况下zookeeper将写数据的日志文件也保存在这个目录里； |
dataLogDir=/opt/soft/zookeeper1/logs |
zookeeper保存日志文件数据 |
clientPort=2181 |
这个端口就是客户端连接Zookeeper服务器的端口,Zookeeper会监听这个端口接受客户端的访问请求 |
server.1= 192.168.1.101:2888:3888 |
server.A=B:C:D中的A是一个数字,表示这个是第几号服务器,B是这个服务器的IP地址，C第一个端口用来集群成员的信息交换,表示这个服务器与集群中的leader服务器交换信息的端口，D是在leader挂掉时专门用来进行选举leader所用的端口。 |
创建数据目录和日志目录
[root@192 ~]# mkdir -p /opt/soft/zookeeper1/{data,logs}
[root@192 ~]# mkdir -p /opt/soft/zookeeper2/{data,logs}
[root@192 ~]# mkdir -p /opt/soft/zookeeper3/{data,logs}
[root@192 ~]# echo "1">/opt/soft/zookeeper1/data/myid
[root@192 ~]# echo "2">/opt/soft/zookeeper2/data/myid
[root@192 ~]# echo "3">/opt/soft/zookeeper3/data/myid
[root@192 ~]# cat /opt/soft/zookeeper1/data/myid
1
[root@192 ~]# cat /opt/soft/zookeeper2/data/myid
2
[root@192 ~]# cat /opt/soft/zookeeper3/data/myid
3
[root@192 ~]#
myid中的值对应server.A=B:C:D中的A
