概率论原理

1.卸载clickhouse

关闭原来的clickhouse

sudo systemctl stop clickhouse-server

查看关闭clickhouse是否成功

sudo systemctl status clickhouse-server

备份配置文件

/etc/clickhouse-server/user.xml

/etc/clickhouse-server/config.d/metrika.xml 

/etc/clickhouse-server/config.xml 

卸载clickhouse和相关组件

sudo apt-get --purge remove clickhouse-server clickhouse-client clickhouse-common-static

删除对应文件夹

rm -rf /var/lib/clickhouse

rm -rf /etc/clickhouse-*

rm -rf /var/log/clickhouse-*

查看对应的文件是否删除完成（若没删除完成直接删除）

find -name clickhouse

2.下载需要的版本的clickhouse

使用命令可以看到可以下载的版本

apt list -a clickhouse-common-static

apt install -y clickhouse-common-static=22.8.9.24

apt install -y clickhouse-{server,client}=22.8.9.24

备份现在的配置文件，将之前备份的配置文件复制过来

/etc/clickhouse-server/user.xml

/etc/clickhouse-server/config.d/metrika.xml 

/etc/clickhouse-server/config.xml 

启动clickhouse

sudo service clickhouse-server start

可以登录clickhouse查看是否成功
