CockroachDB 拥有复杂而现代的架构，专为全球规模而设计。 然而，这种复杂性和可扩展性并不意味着学习曲线陡峭或入门门槛高。 在本章中，我们将帮助你开始安装 CockroachDB，并向你介绍使用 CockroachDB 系统的基础知识。
安装
CockroachDB 几乎可以在几分钟内安装到任何类型的桌面操作系统上。 另外，你也可以创建一个免费的 CockroachDB 无服务器数据库，或者在 Docker 容器或 Kubernetes 集群中运行 CockroachDB。
安装 CockroachDB 软件
在大多数情况下，你会希望在台式电脑上安装CockroachDB 软件，所以让我们从这开始。你可以在https://www.cockroachlabs.com/docs/releases 找到 CockroachDB 二进制文件的完整列表。 在那里，你可以选择你的操作系统，下载最新版本或以前的版本。
以下说明在撰写本文时有效，但每次版本发布后，安装方式都会发生变化，因此请务必查阅 CockroachDB 网站，以获取最新说明。
在 macOS 上安装
如果你已经安装了 brew 软件包管理器，那么这可能是在 Mac 上开始安装 CockroachDB 的最简单方法。 事实上，即使你没有安装 brew，安装它然后再安装 CockroachDB 可能比手动安装 CockroachDB 更简单。
要安装 brew，请在终端窗口中发出以下命令：
/bin/bash -c \ "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh
brew 安装完成后，可以使用以下命令安装 CockroachDB：
guyharrison@macos ~ % brew install cockroachdb/tap/cockroach ==> Tapping cockroachdb/tap Cloning into '/usr/local/Homebrew/Library/Taps/cockroachdb/homebrew-tap'... … ==> Installing cockroach from cockroachdb/tap …. To have launchd start cockroachdb/tap/cockroach now and restart at login: brew services start cockroachdb/tap/cockroach Or, if you don't want/need a background service you can just run: cockroach start-single-node --insecure ==> Summary 🍺 usr/local/Cellar/cockroach/20.2.7: 134 files, 184.8MB, built in 8 sec
brew 的好处之一是它可以将 CockroachDB 设置为服务，因此你可以发布brew services start cockroach 来启动 CockroachDB 的后台实例。不过，如果你不想使用 brew，那么你可以直接下载 CockroachDB 二进制文件，然后将二进制文件复制到你的路径中。 ...
