搭建zookeeper集群

news 来源：原创 2024/5/17 19:44:29

三台环境

10.99.33.251 clickhouse01
10.99.33.252 clickhouse02
10.99.33.253 clickhouse03

以下步骤在三台机器上都需要操作

vim /etc/hosts
10.99.33.251 clickhouse01.hmtech.com
10.99.33.252 clickhouse02.hmtech.com
10.99.33.253 clickhouse03.hmtech.com

下载&解压&转移zookeeper包

wget https://dlcdn.apache.org/zookeeper/zookeeper-3.7.1/apache-zookeeper-3.7.1-bin.tar.gz
tar xf apache-zookeeper-3.7.1-bin.tar.gz
mkdir /apps
mv apache-zookeeper-3.7.1-bin /apps/
cd cd /apps/apache-zookeeper-3.7.1-bin/conf/
cp zoo_sample.cfg zoo.cfg

编辑zoo.cfg文件

vim /apps/apache-zookeeper-3.7.1-bin/conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/apps/apache-zookeeper-3.7.1-bin/data/zookeeper
dataLogDir=/apps/apache-zookeeper-3.7.1-bin/log/zookeeper
clientPort=2182
autopurge.snapRetainCount=0

server.251=10.99.33.251:2888:3888
server.252=10.99.33.252:2888:3888
server.253=10.99.33.253:2888:3888

创建数据目录

mkdir {data,log}
mkdir data/zookeeper

在每台服务器上分配创建myid文件

[root@clickhouse01 ~]# cat /apps/apache-zookeeper-3.7.1-bin/data/zookeeper/myid
251

[root@clickhouse02 ~]# cat /apps/apache-zookeeper-3.7.1-bin/data/zookeeper/myid
252

[root@clickhouse03 ~]# cat /apps/apache-zookeeper-3.7.1-bin/data/zookeeper/myid
253

先删除本机现有的Java&安装java

yum -y remove java && yum install fontconfig java-11-openjdk

配置环境变量

cd /usr/lib/jvm/java-11-openjdk-11.0.16.0.8-1.el7_9.x86_64/

vim /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.16.0.8-1.el7_9.x86_64
export CLASSPATH=.: $JAVA_HOME/lib/dt.jar:$ JAVA_HOME/lib/tools.jar
export PATH= $P A T H :$ JAVA_HOME/bin:$PATH

source /etc/profile

启动zookeeper

./bin/zkServer.sh start

配置zookeeper服务自启

[root@clickhouse01 ~]# cat /etc/rc.d/init.d/zookeeper
#!/bin/bash
#chkconfig:2345 20 90
#description:zookeeper
#processname:zookeeper
case $1 in
start)
sh /apps/apache-zookeeper-3.7.1-bin/bin/zkServer.sh start
;;
stop)
sh /apps/apache-zookeeper-3.7.1-bin/bin/zkServer.sh stop
;;
status)
sh /apps/apache-zookeeper-3.7.1-bin/bin/zkServer.sh status
;;
restart)
sh /apps/apache-zookeeper-3.7.1-bin/bin/zkServer.sh restart
;;
*)
echo “Usage:$0(start|stop|status|restart)”
;;
esac
exit
