Arch Manjaro Linux Pacman 和 Aur 配置多线程下载

本文主要是介绍Arch Manjaro Linux Pacman 和 Aur 配置多线程下载，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

0x01 配置 Pacman 多线程下载

sudo pacman -S axel  

sudo gedit /etc/pacman.conf  

注销已有的 XferCommand 新增一行

XferCommand = /usr/bin/axel -a -n 16 %u -o %o

20190518 更新说明：今天测试发现 axel -a 参数会出现段错误，可能是 axel 的问题，去掉 -a 恢复正常。以下配置也要改更，后续会不会修复这个问题暂时不清楚。

XferCommand = /usr/bin/axel -n 16 %u -o %o

保存并退出

sudo pacman -Syyu

# REPOSITORIES
#   - can be defined here or included from another file
#   - pacman will search repositories in the order defined here
#   - local/custom mirrors can be added here or in separate files
#   - repositories listed first will take precedence when packages
#     have identical names, regardless of version number
#   - URLs will have $repo replaced by the name of the current repo
#   - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
#       [repo-name]
#       Server = ServerName
#       Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
## The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.[core]

0x02 配置 Yaourt、Yay（其他 aur 管理工具还没测试）

sudo gedit /etc/makepkg.conf  

注销已有的 'http::/usr/bin/curl… 新增一行

~~'http::/usr/bin/axel -a -n 16 %u -o %o'~~ 
'http::/usr/bin/axel -n 16 %u -o %o'

保存并退出

yaourt -Syyu

已测试 yay 通过。其余暂未验证。
理论上使用 makepkg.conf 配置文件的 aur 管理工具都支持多线程下载。
