Background: Using Arch Linux.
P.S. After updating conf file, you should restart the program.

# At pacalis.conf
[manjaro-core]
Dest = https://mirrors.tuna.tsinghua.edu.cn/manjaro/unstable/core/$arch
OName = core
[manjaro-extra]
Dest = https://mirrors.tuna.tsinghua.edu.cn/manjaro/unstable/extra/$arch
OName = extra

# At pacman.conf
[manjaro-core]
Server = http://127.0.0.1:2090/?repo=$repo&arch=$arch&file=
[manjaro-extra]
Server = http://127.0.0.1:2090/?repo=$repo&arch=$arch&file=
