Bluesky是一个去中心化的分散式社交系统，与 Mastodon (长毛象) 相似，不过Bluesky 自行开发的AT Protocol协议无法与 Mastodon 的 ActivityPub 互通。 同样是可自行架设的社交平台，比较特别的是 Bluesky 并不像 Mastodon 一样包含了前端网页(web)，它只有提供API功能，需要专门的前端来进行登录管理。 自行部署的Bluesky服务器被称为个人数据服务器 (Personal Data Server, PDS)，使用者可以在 bsky.app 网页版或 iOS、Android客户端中登录自行部署的pds服务。 pds推荐主机配置 操作系统 Ubuntu 22.04 内存 (RAM) 1 GB CPU核心 1 CPU构架 amd64, arm64 硬盘 20 GB SSD 可服务账号数 20 VPS部署PDS实例 域名设置 以pds.p9.pub为例，服务器IP为195.192.118.6 将pds.p9.pub和*.pds.p9.pub的A记录修改为195.192.118.6 安装pds 通过以下命令下载安装脚本 wget https://raw.githubusercontent.com/bluesky-social/pds/main/installer.sh 然后运行bash ./installer.sh来开始安装 bash ./installer.sh * Detected supported distribution Debian 12 --------------------------------------- Add DNS Record for Public IP --------------------------------------- From your DNS provider's control panel, create the required DNS record with the value of your server's public IP address. + Any DNS name that can be resolved on the public internet will work. + Replace example.com below with any valid domain name you control. + A TTL of 600 seconds (10 minutes) is recommended.

alias其实就是一个命令的快捷方式，为了将复杂的命令简化成简洁的样子。比如我们常用的ll命令其实就是ls -l命令的alias，这里的ll就是一个alias。 显示alias 使用alias显示当前所有别名，默认情况下将显示当前用户定义的所有alias $ alias alias ..='cd ..' alias ipython='winpty ipython.exe' alias ll='ls -l' alias ls='ls -F --color=auto --show-control-chars' alias ts='date +%s' 定义新的alias 定义新的alias方法如下： alias 名称=值 alias 名称='命令' alias 名称='命令 参数1 参数2' alias 名称='/路径/脚本' alias 名称='/路径/脚本.pl 参数1' 我们常用clear命令来清屏，但每次输入clear有点长，那么就可以为其定义一个简洁的alias。 alias c='clear' 通过以上操作，就为clear命令定义了一个名为c的alias，那么下次输入c命令就相当于执行了clear命令。 提示：可以将alias定义添加到~/.bashrc文件中以保证每次重启都会生效。 临时禁用alias 对于已经定义的alias可以使用以下方法临时禁用。 ## 命令完整目录 /usr/bin/clear ## 使用反斜杠忽略alias \c ## 使用/bin/ls命令并忽略ls的alias command ls 删除alias 想要删除已经定义的alias，就需要使用unalias命令，使用实例如下： ## 使用alias $ ll total 10 -rw-r--r-- 1 bbq 197121 411 Jun 10 2023 id_ed25519 -rw-r--r-- 1 bbq 197121 96 Jun 10 2023 id_ed25519.pub -rw-r--r-- 1 bbq 197121 1957 Aug 14 18:36 known_hosts -rw-r--r-- 1 bbq 197121 1109 Aug 6 15:23 known_hosts.old ## 删除alias $ unalias ll ## 提示alias不存在了 $ ll bash: ll: command not found 提示：如果你将alias添加到~/.bashrc文件中，记得也要删除。 ...
