问题

最近需要试用clklog数据收集的社区版，clklog用数据库是Clickhouse。这就需要我先单机部署一个Clickhouse数据库，先试用试用。

步骤

这里假设我们已经拥有一台Ubuntu的服务器了，现在我们需要在这台机器上面安装Clickhouse数据库。Clickhouse官方推荐生产环境是要集群部署的，我这里只是单机试用，不能作为生产环境使用。

添加apt存储库

sudo apt-get install -y apt-transport-https ca-certificates curl gnupg
curl -fsSL 'https://packages.clickhouse.com/rpm/lts/repodata/repomd.xml.key' | sudo gpg --dearmor -o /usr/share/keyrings/clickhouse-keyring.gpgARCH=$(dpkg --print-architecture)
echo "deb [signed-by=/usr/share/keyrings/clickhouse-keyring.gpg arch=${ARCH}] https://packages.clickhouse.com/deb stable main" | sudo tee /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

安装指定版本数据库

sudo apt-get install -y clickhouse-server=25.3.2.39 clickhouse-client=25.3.2.39 clickhouse-common-static=25.3.2.39

安装数据库的过程中，会提示你需要设置数据库密码。下面设置数据库随机启动，具体如下：

# 启用随机启动
sudo systemctl enable clickhouse-server
# 启动数据库
sudo systemctl start clickhouse-server
# 查看数据库状态
sudo systemctl status clickhouse-server

登录数据库

clickhouse-client -u default

然后输入数据库密码即可。具体效果如下：

ClickHouse client version 25.3.2.39 (official build).
Connecting to localhost:9000 as user default.
Password for user (default):
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 25.3.2.Warnings:* Available memory at server startup is too low (2GiB).* Maximum number of threads is lower than 30000. There could be problems with handling a lot of simultaneous queries.* Delay accounting is not enabled, OSIOWaitMicroseconds will not be gathered. You can enable it using `echo 1 > /proc/sys/kernel/task_delayacct` or by using sysctl.* Linux threads max count is too low. Check /proc/sys/kernel/threads-maxip-10-0-2-43.cn-north-1.compute.internal :)
