安装Clickhouse服务

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates dirmngr
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 8919F6BD2B48D754

sudo apt-get update

apt-cache madison clickhouse-server | head -n5

sudo apt-get install -y clickhouse-server=22.8.5.29 clickhouse-client=22.8.5.29

# 修改clickhouse的家目录以及相关属主组
mkdir /home/clickhouse

chown -R clickhouse.clickhouse /home/clickhouse

usermod -d /home/clickhouse clickhouse

# 准备clickhouse的数据存储目录
mkdir /data/clickhouse_bigdata

chown -R clickhouse.clickhouse /data/clickhouse_bigdata

# 在clickhouse的默认配置文件中修改clickhouse的数据目录
sed -e 's#/var/lib/clickhouse#/data/clickhouse_bigdata#g' /etc/clickhouse-server/config.xml |grep -i '/data/clickhouse_bigdata'

sed -i 's#/var/lib/clickhouse#/data/clickhouse_bigdata#g' /etc/clickhouse-server/config.xml |grep -i '/data/clickhouse_bigdata'

# sudo service clickhouse-server start
# clickhouse-client # or "clickhouse-client --password" if you've set up a password.

配置节点域名解析

⚠️ 每个节点都需要配置

• [x] 本地host配置

cat >> /etc/hosts << EOF
10.0.10.195 cknode1.devopsman.cn bigdata1 
10.0.10.194 cknode2.devopsman.cn bigdata2
10.0.10.196 cknode3.devopsman.cn bigdata3
EOF

• DNS解析平台上进行解析

ClickHouse 的集群配置

配置切片和副本remote-servers.xml

在所有的配置文件配置完成后，切记要修改xml文件的所属属性

chown clickhouse.clickhouse /etc/clickhouse-server/config.d/*.xml /etc/clickhouse-server/users.d/*.xml
