clickhouse 单机体验

这里使用的是clickhouse 18.6.0版本，运行环境为CentOS 7.4

官方提供的软件版本支持docker和deb包，官方推荐使用Ubuntu操作系统，但是在国内服务器多是CentOS。

1.软件RPM下载：

#cat clickhouse_download.sh
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-server-common-18.6.0-1.el7.x86_64.rpm/download.rpm
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-test-18.6.0-1.el7.x86_64.rpm/download.rpm
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-server-18.6.0-1.el7.x86_64.rpm/download.rpm
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-common-static-18.6.0-1.el7.x86_64.rpm/download.rpm
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-client-18.6.0-1.el7.x86_64.rpm/download.rpm
wget --content-disposition https://packagecloud.io/Altinity/clickhouse/packages/el/7/clickhouse-debuginfo-18.6.0-1.el7.x86_64.rpm/download.rpm

2.软件安装需要依赖2个额外的包 libtool-ltdl和unixODBC，推荐使用yum 安装：

查看需要安装的软件包：
#ls -l
clickhouse-client-18.6.0-1.el7.x86_64.rpm         
clickhouse-server-18.6.0-1.el7.x86_64.rpm         
clickhouse-test-18.6.0-1.el7.x86_64.rpm
clickhouse-common-static-18.6.0-1.el7.x86_64.rpm
