公司项目上需求使用Clickhouse，记录下单机版的安装步骤，选择的是rpm包方式安装
本例是在CentOS7上安装部署到/app目录下
1、下载所需安装包
从下载地址中下载所需版本的安装包，一般是5个安装包。
2、以如下顺序，rpm方式安装
rpm -ivh clickhouse-common-static-20.3.11.97-1.el7.x86_64.rpm
rpm -ivh clickhouse-server-common-20.3.11.97-1.el7.x86_64.rpm
rpm -ivh clickhouse-server-20.3.11.97-1.el7.x86_64.rpm
rpm -ivh clickhouse-client-20.3.11.97-1.el7.x86_64.rpm
3、创建目录
mkdir -p /app/clickhouse/log
mkdir -p /app/clickhouse/data
mkdir -p /app/clickhouse/data_old
mkdir -p /app/clickhouse/tmp/
mkdir -p /app/clickhouse/format_schemas/
mkdir -p /app/clickhouse/user_files/
4、修改启动脚本vim /etc/init.d/clickhouse-server 修改以下参数：
CLICKHOUSE_LOGDIR=/app/clickhouse/log
CLICKHOUSE_LOGDIR_USER=root
CLICKHOUSE_DATADIR_OLD=/app/clickhouse/data_old
CLICKHOUSE_DATADIR=/app/clickhouse/data
5、修改config.xml中的目录地址，vim /etc/clickhouse-server/config.xml:
<path>/app/clickhouse/data/</path>
<tmp_path>/app/clickhouse/tmp/</tmp_path>
<user_files_path>/app/clickhouse/user_files/</user_files_path>
<format_schema_path>/app/clickhouse/format_schemas/</format_schema_path>
6、启动和验证ClickHouse服务
service clickhouse-server start
clickhouse-client -m
7、添加开机自启动
chkconfig clickhouse-server on
