Linux安装zookeeper

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/software

tar -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 PATH


source /etc/profile

配置zookeeper

1, myid

cd /usr/local/applications/zookeeper-3.8.4/

mkdir data
mkdir logs

cd data

echo 1 > myid

2, zoo.conf

cd /usr/local/applications/zookeeper-3.8.4/conf

mv zoo_sample.cfg zoo.cfg

vi zoo.cfg

dataDir=/usr/local/applications/zookeeper-3.8.4/data
dataLogDir=/usr/local/applications/zookeeper-3.8.4/logs

server.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/applications

scp -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
