iSH的浅折腾记录

闲来没事折腾折腾苹果上的ish，这东西比Termux难用：比如清华的一键换源命令不能用，默认给的是root用户，用的还是x86的包。

本质上还是相当于折腾Alpine Linux

从0开始装到能用ssh

第0步当然是去AppStore里下载iSH

换清华源还是可以换的，只不过不能用官方的换源命令了，得改一下：

sed -i 's/apk.ish.app\/v3.14-2023-05-19/mirrors.tuna.tsinghua.edu.cn\/alpine\/v3.14/g' /etc/apk/repositories

至于清华的换源命令为什么不能用….我们来看一下/etc/apk/repositories文件里是啥:

# This file contains pinned repositories managed by iSH. If the /ish directory
# exists, iSH uses the metadata stored in it to keep this file up to date (by
# overwriting the contents on boot.)
http://apk.ish.app/v3.14-2023-05-19/main
http://apk.ish.app/v3.14-2023-05-19/community

清华的换源脚本会找不到匹配的字符串，所以得把更换的地方给调整一下。把repositories文件变成这样就行：

# This file contains pinned repositories managed by iSH. If the /ish directory
# exists, iSH uses the metadata stored in it to keep this file up to date (by
# overwriting the contents on boot.)
http://mirrors.tuna.tsinghua.edu.cn/alpine/v3.14/main
http://mirrors.tuna.tsinghua.edu.cn/alpine/v3.14/community

添加用户：

apk add sudo
adduser username
addgroup username wheel

到这里用户就建完了，给他加到wheel用户组里以可以执行sudo命令：

visudo
# 找到%wheel ALL=(ALL) NOPASSWD: ALL前面的#，删掉他然后保存退出

开整openssh：

apk add openssh openssh-server
ssh-keygen -A

SSH，启动！

/usr/sbin/sshd

注意iSH中必须用绝对路径启动sshd，否则会报错说sshd re-exec requires execution with an absolute path
这个时候将你的公钥传到/home/username/.ssh/authorized_keys中，就可以连上了！

PS C:\Users\admin> ssh admin@192.168.1.102
Enter passphrase for key 'C:\Users\admin/.ssh/id_rsa':
Welcome to Alpine!

安装OMZ

你得先安装shadow，要不然在chsh的时候会出错。

apk add shadow

这就跟别的电脑上安装步骤一样了没啥区别。

sudo apk add git zsh
git clone --depth=1 https://github.com/ohmyzsh/ohmyzsh.git
cd ohmyzsh
cd tools
sh install.sh
