一：系统环境部署介绍

1.1：系统初始化

系统：
   centos7.9x64

 主机名字:
   cat /etc/hosts 

   -----

172.16.10.11    flyfishsrvs01
172.16.10.12    flyfishsrvs02
172.16.10.13    flyfishsrvs03
172.16.10.14    flyfishsrvs04

172.16.10.16    flyfishsrvs06
172.16.10.17    flyfishsrvs07 

   ------
  本次部署前四台服务器 

1.2 系统部署jdk

在flyfishsrvs02,flyfishsrvs03,flyfishsrvs04 上面部署

tar -zxvf jdk-8u301-linux-x64.tar.gz
mv jdk1.8.0_301/ /usr/local/jdk
vim /etc/profile 
----

### jdk
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
----

source /etc/profile

java -version 

1.3 配置zookeeper 集群

在flyfishsrvs02,flyfishsrvs03,flyfishsrvs04 上面部署
tar -zxvf apache-zookeeper-3.7.0-bin.tar.gz
mv apache-zookeeper-3.7.0-bin /usr/local/zookeeper

mkdir -p /usr/local/zookeeper/data
mkdir -p /usr/local/zookeeper/log

cd /usr/local/zookeeper/data/

echo 1 > myid
----
cd /usr/local/zookeeper/conf 

cp zoo_sample.cfg zoo.cfg 

vim zoo.cfg 

----
# 心跳时间
tickTime=2000
# follow连接leader的初始化连接时间，表示tickTime的倍数
initLimit=10
# syncLimit配置表示leader与follower之间发送消息，请求和应答时间长度。如果followe在设置的时间内不能与leader进行通信，那么此follower将被丢弃，tickTime的倍数
syncLimit=5
# 客户端连接端口
clientPort=2181
# 节点数据存储目录，需要提前创建，注意myid添加，用于标识服务器节点
dataDir=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/log
server.1=172.16.10.12:2888:3888
server.2=172.16.10.13:2888:3888
server.3=172.16.10.14:2888:3888
---
-----

scp -r zookeeper root@172.16.10.13:/usr/local/
scp -r zookeeper root@172.16.10.14:/usr/local/
修改172.16.10.13 节点 myid 
cd /usr/local/zookeeper/data/
echo 2 > myid 
修改172.16.10.14 节点 myid
cd /usr/local/zookeeper/data/
echo 3 > myid

启动zookeeper 

cd /usr/local/zookeeper/bin/

./zkServer.sh start

二： 部署clickhouse 21.x

2.1 安装clickhouse 21.x

rpm -ivh clickhouse-* [所有节点都安装处理]

修改listen_host

vim +164 /etc/clickhouse-server/config.xml

----
<listen_host>::1</listen_host>
<listen_host>flyfishsrvs01</listen_host>  ### 其它节点修改对于主机名
-----

2.2 配置集群文件

配置集群连接文件
cd /etc/clickhouse-server/config.d
vim metrika.xml 
-----

2.3 集群启动与验证

修改对应节点的副本主机名
vim 
#flyfishsrvs02节点修改metrika.xml中的宏变量如下： 
<macros> 
<shard>02</replica>
<replica>flyfishsrvs02</replica> 
</macros> 
#flyfishsrvs03节点修改metrika.xml中的宏变量如下: 
<macros> 
<shard>03</replica>
<replica>flyfishsrvs03</replica> 
</macros>

#flyfishsrvs04节点修改metrika.xml中的宏变量如下: 
<macros> 
<shard>04</replica>
<replica>flyfishsrvs04</replica> 
</macros>

#每台节点启动Clickchouse服务 
service clickhouse-server start
#每台节点查看clickhouse服务状态 
service clickhouse-server status 
#每台节点重启clickhouse服务 
service clickhouse-server restart 
#每台节点关闭Clikchouse服务 
service clickhouse-server stop

验证：
clickhouse-client -h flyfishsrvs01
查看集群：
select * from system.clusters;
select cluster,host_name from system.clusters;

其它节点验证：
select * from system.clusters;
select cluster,host_name from system.clusters;
