一、安装环境

1、官方最低要求

• Docker 版本：20.10.0 及以上
• 节点配置：4 核 CPU，8 GB 内存

2、自己实际环境

1、硬件环境

2、软件环境

---

二、安装文档

因为是自己机器安装，机器配置一般，所以只能选择 Docker Compose安装。

---

三、安装步骤

1、执行脚本

打开自己的iTerm2运行如下脚本

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/erda-project/erda/master/quick-start/quick-start.sh)"

遇到问题一：执行过程中有可能（如果网络正常就不会碰到）碰到443错误，如下图所示

原因：网络偶尔有异常（raw.githubusercontent.com 域用于提供存储在GitHub存储库中的文件的未处理版本）
解决：两种方式

• 方式一：搭建翻墙工具或者切换网络（我的情况是网络有异常，什么都没操作过了一会自己就正常）
• 方式二：将下面shell保存到本地，然后运行。但是远程erda的脚本有可能变更；

效果：刷刷刷，程序运行起来了，如下图

遇到问题二：文件夹缺少权限
现象：文件 is not shared ,具体如下

Creating erda-migration ... error
ERROR: for erda-migration  Cannot start service erda-migration: Mounts denied:
The path /opt/erda-quickstart/.erda/migrations is not shared from the host and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> Resources -> File Sharing.
See https://docs.docker.com/docker-for-mac for more info.
ERROR: for erda-migration  Cannot start service erda-migration: Mounts denied:
The path /opt/erda-quickstart/.erda/migrations is not shared from the host and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> Resources -> File Sharing.
See https://docs.docker.com/docker-for-mac for more info.
ERROR: Encountered errors while bringing up the project.
Failed during: docker-compose up erda-migration

原因：erda安装过程中会创建一个/opt/erda-quickstart文件夹，但是该文件夹没有被shared，导致docker执行文件夹下命令时候Mounts denied
解决：将该文件夹shared，操作Docker -> Preferences… -> Resources -> File Sharing.如下图

文件夹共享后，可以重新执行下/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/erda-project/erda/master/quick-start/quick-start.sh)” 最终看到successfully

2、访问平台

浏览器上直接访问 http://erda.local
注：erda安装过程中给本机hosts里添加了一行数据，所以可以通过上面域名访问

127.0.0.1 erda.local one.erda.local

系统进入一个登录页面，没有账密（erda为何不给数据库中主动插入一条账户数据呢？），选择注册用户，注册成功后进入主页

遇到问题一：当前页面不存在
http://one.erda.local/-/sysAdmin/orgs

问题原因：注意到该页面地址为 sysAdmin/orgs，即超级管理员管理页，该模块暂时还未包含在开源包内（我们将在近期开放该模块）。Erda 首次注册到账号会默认成为超级管理员，因此会自动尝试跳转到该页面。
解决方法：您可以退出首次注册的账号，然后再次注册一个新账号，使用新的账号登录后将会跳转到个人仪表盘页面，如下图所示，您可以从点击页面左上方的 创建机构 按钮开始体验 Erda。

重新注册第二个用户后终于可以正常使用。PS第一个账户注册时候密码没有要求，注册第二个账户密码有一定长度+强弱要求；

后续其他操作见erda官网文档
