下载并上传

zookeeper-3.5.3-beta.tar.gz

到各个服务器的/soft/zookeeper目录,或者使用wget命令，如下：

cd /soft/zookeeperwget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.5.3-beta/zookeeper-3.5.3-beta.tar.gztar -xvf zookeeper-3.5.3-beta.tar.gz

在各个服务器上解压zookeeper安装包，并按节点号对zookeeper目录重命名

# 服务器1cp -r zookeeper-3.5.3 zookeeper-3.5.3_1# 服务器2cp -r zookeeper-3.5.3 zookeeper-3.5.3_2# 服务器3cp -r zookeeper-3.5.3 zookeeper-3.5.3_3

在各zookeeper节点目录下创建以下目录

cd /soft/zookeeper/zookeeper-3.5.3_1mkdir datamkdir logscd /soft/zookeeper/zookeeper-3.5.3_2mkdir datamkdir logscd /soft/zookeeper/zookeeper-3.5.3_3mkdir datamkdir logs

将各节点zookeeper/zookeeper-3.5.3_x/conf目录下的zoo_sample.cfg文件拷贝一份，命名为zoo.cfg:

cd /soft/zookeeper/zookeeper-3.5.3_1/confcp zoo_sample.cfg zoo.cfgcd /soft/zookeeper/zookeeper-3.5.3_2/confcp zoo_sample.cfg zoo.cfgcd /soft/zookeeper/zookeeper-3.5.3_3/confcp zoo_sample.cfg zoo.cfg

修改 zoo.cfg 配置文件

ip:192.168.159.128(虚拟机ip)

cd /soft/zookeeper/zookeeper-3.5.3_1/conf# 设置内容如下：tickTime=2000initLimit=10syncLimit=5dataDir=/soft/zookeeper/zookeeper-3.5.3_1/datadataLogDir=/soft/zookeeper/zookeeper-3.5.3_1/logsclientPort=2181server.1=192.168.159.128:2881:3881server.2=192.168.159.128:2882:3882server.3=192.168.159.128:2883:3883# -----------------------------------cd /soft/zookeeper/zookeeper-3.5.3_2/confvi zoo.cfg# 设置内容如下：tickTime=2000initLimit=10syncLimit=5dataDir=/soft/zookeeper/zookeeper-3.5.3_2/datadataLogDir=/soft/zookeeper/zookeeper-3.5.3_2/logsclientPort=2182server.1=192.168.159.128:2881:3881server.2=192.168.159.128:2882:3882server.3=192.168.159.128:2883:3883# -----------------------------------cd /soft/zookeeper/zookeeper-3.5.3_3/confvi zoo.cfg# 设置内容如下：tickTime=2000initLimit=10syncLimit=5dataDir=/soft/zookeeper/zookeeper-3.5.3_3/datadataLogDir=/soft/zookeeper/zookeeper-3.5.3_3/logsclientPort=2183server.1=192.168.159.128:2881:3881server.2=192.168.159.128:2882:3882server.3=192.168.159.128:2883:3883

在dataDir=/soft/zookeeper/zookeeper-3.5.3_x/data下创建 myid 文件

vi /soft/zookeeper/zookeeper-3.5.3_1/data/myid #设置值为1vi /soft/zookeeper/zookeeper-3.5.3_2/data/myid #设置值为2vi /soft/zookeeper/zookeeper-3.5.3_3/data/myid #设置值为3

启动并查看zookeeper:

cd /soft/zookeeper/soft/zookeeper/zookeeper-3.5.3_1/bin/zkServer.sh start/soft/zookeeper/zookeeper-3.5.3_2/bin/zkServer.sh start/soft/zookeeper/zookeeper-3.5.3_3/bin/zkServer.sh start

验证zookeeper启动情况

/soft/zookeeper/zookeeper-3.5.3_1/bin/zkServer.sh status/soft/zookeeper/zookeeper-3.5.3_2/bin/zkServer.sh status/soft/zookeeper/zookeeper-3.5.3_3/bin/zkServer.sh status

如果启动成功，三台机器结果类似如下,标红部分为一个leader,两个follower：

[root@centos7 local]# /soft/zookeeper/zookeeper-3.5.3_1/bin/zkServer.sh statusJMX enabled by defaultUsing config: /soft/zookeeper/zookeeper-3.5.3_1/bin/../conf/zoo.cfgMode: "follower"[root@centos7 local]# /soft/zookeeper/zookeeper-3.5.3_2/bin/zkServer.sh statusJMX enabled by defaultUsing config: /soft/zookeeper/zookeeper-3.5.3_2/bin/../conf/zoo.cfgMode: "leader"[root@centos7 local]# /soft/zookeeper/zookeeper-3.5.3_3/bin/zkServer.sh statusJMX enabled by defaultUsing config: /soft/zookeeper/zookeeper-3.5.3_3/bin/../conf/zoo.cfgMode: "follower"
