前言

事情的起因非常简单，得益于某位校长的功劳，我的网络访问 Github 奇慢无比，最近甚至出现了 push 失败的情况，我连博客都没法好好更新了！~~（说的好像你更新得很多一样）~~
嘛，正好潇在给我孜孜不倦地推荐Gitea，我就来试试在树莓派上搭建一下吧。
首先我们来看官方文档：

易安装
您除了可以根据操作系统平台通过二进制运行，还可以通过 Docker 或 Vagrant，以及包管理安装。

嚯，挺厉害嘛，那就图个省事，用 Docker 安装吧。然而这之后我才知道，这是地狱的开始。

Docker 试探

安装

官方的教程非常的简单，~~看起来就和能用一样~~

我们在 Docker Hub 的 Gitea 组织中提供了自动更新的 Docker 镜像，它会保持最新的稳定版。你也可以用其它 Docker 服务来更新。首先你需要 pull 镜像：

1
2
3

docker pull gitea/gitea:latest
sudo mkdir -p /var/lib/gitea //如果要将git和其它数据持久化，你需要创建一个目录来作为数据存储的地方
docker run -d --name=gitea -p 10022:22 -p 10080:3000 -v /var/lib/gitea:/data gitea/gitea:latest //然后就可以运行 docker 容器了，这很简单。 当然你需要定义端口数数据目录：

这时候我才发现我根本就没有安装 docker，赶紧 apt 解决：

1	apt install docker

然后开始 pull，这时又要忍受国内网络的龟速：

docker pull gitea/gitea:latest
latest: Pulling from gitea/gitea
911c6d0c7995: Pull complete
fe8708a98e1d: Pull complete

Status: Downloaded newer image for gitea/gitea:latest

受阻

尝试运行一下

1

3

# root @ rasp in ~ [14:46:44]
$ docker run -d --name=gitea -p 10022:22 -p 10080:3000 -v /mnt/disk/Git:/data gitea/gitea:latest
ee43cb4883e4d6e75f0eea1c8b90988880c1569b7088bc1f072274f2a2eaf4dc

没有回显，不过还是先看看容器跑起来没有:

1
2
3

# root @ rasp in ~ [14:46:54]
$ docker logs gitea
standard_init_linux.go:185: exec user process caused "exec format error"

喵喵喵？这尼玛是啥？看起来好像是可执行文件架构不对。。

原因分析

兔角龟毛，总之先 inspect 一下吧

1 2	# root @ rasp in ~ [14:55:17] $ docker inspect gitea/gitea:latest

得到如下结果:

やっぱり！™ 这个文档谁写的！头伸过来，看我不来给你加个 bug，你写这个文档的时候就没考虑过其他架构的 CPU 的感受么！你是不是看不起 ARM！！

最后的挣扎

嘛，既然这样了，摆在我面前也就三条路:

制作基于 ARM64 的 docker 容器
放弃 docker
玩一些骚操作
首先来看看骚操作，既然它的运行依靠的是单文件，那我如果下载 arm64 的二进制文件手动替换，不就可以运行了么？
但是事实狠狠的打了我的脸，前面的替换进行地很顺利，直到…

惹不起，惹不起，告辞！
至于编译，我实在不想弄，理由如下：
首先，有了上次编译驱动的经历之后，我是再也不想在树莓派上编译任何东西了。且不说 CPU 的弱鸡，光是内存不足就足够你喝一壶的。至于交叉编译？不好意思，编译之神 Baymax 持续掉线中。

二进制安装

那就只有来二进制文件了。
嘛，这个就没啥说的了，直接参照官方教程就好了。
配置文件随便根据官网改改就好，这里就不贴出来。

最终效果

Gitea
嘛，就是这样，试过了速度还行。还拥有镜像功能，可以自动追踪某一个远程仓库，以后有啥小项目就决定是你了！
