1, 下载

Apache ZooKeeperhttps://zookeeper.apache.org/releases.htmlhttps://zookeeper.apache.org/releases.htmlhttps://zookeeper.apache.org/releases.htmlhttps://zookeeper.apache.org/releases.htmlhttps://zookeeper.apache.org/releases.htmlhttps://zookeeper.apache.org/releases.html从Apache官网下载最新可用版本 apache-zookeeper-3.8.4-bin.tar.gz。

上传到linux 虚拟机某个路径 /opt/software

2，解压缩

解压缩，并且重命名。

cd /opt/softwaretar -zxvf apache-zookeeper-3.8.4-bin.tar.gz -C /usr/local/applications/cd /usr/local/applications/mv apache-zookeeper-3.8.4-bin zookeeper-3.8.4

3，配置

环境变量

三台linux server同时配置 /etc/profile

vi /etc/profile#zookeeper_config
ZOOKEEPER_HOME=/usr/local/applications/zookeeper-3.8.4
PATH=$PATH:$ZOOKEEPER_HOME/bin
export ZOOKEEPER_HOME PATHsource /etc/profile

配置zookeeper

1, myid

cd /usr/local/applications/zookeeper-3.8.4/mkdir data
mkdir logscd dataecho 1 > myid

2, zoo.conf

cd /usr/local/applications/zookeeper-3.8.4/confmv zoo_sample.cfg zoo.cfgvi zoo.cfgdataDir=/usr/local/applications/zookeeper-3.8.4/data
dataLogDir=/usr/local/applications/zookeeper-3.8.4/logsserver.1=localhost1:2888:3888
server.2=localhost2:2888:3888
server.3=localhost3:2888:3888

3, 将配置好的zookeeper 远程复制到另外两台server

cd /usr/local/applicationsscp -r zookeeper-3.8.4 root@localhost2:/usr/local/applications/zookeeper-3.8.4
scp -r zookeeper-3.8.4 root@localhost3:/usr/local/applications/zookeeper-3.8.4

4, 修改另外两台server的“myid”文件中的内容

localhost1是1，localhost2是2，localhost3是3

4，Linux时钟同步

安装`ntpd`

yum install ntp

启动并启用`ntpd`服务

systemctl start ntpd
systemctl enable ntpd

同步时区

timedatectl set-timezone Asia/Shanghai

5, 启动zookeeper

三台Linux server 分别执行启动

cd /usr/local/applications/zookeeper-3.8.4/bin./zkServer.sh start

关闭命令

./zkServer.sh stop
