Mirror List

Switching Gentoo’s sources happens in two parts: the Portage tree (the ebuilds and metadata for packages — best synced over git, though rsync works too) and Distfiles (the package source tarballs, served over HTTP and configured via GENTOO_MIRRORS in make.conf).

Below is a tested summary table showing at a glance what each mirror supports; the per-method config is in the collapsible tutorials further down.

Recommended combo: sync the Portage tree over git (incremental updates, fast and stable) plus a nearby distfiles mirror. If you’re not sure what to put, just pick whichever region in the table is closest to you.

Overview

Every node has been individually tested; ✓ = verified working. The distfiles URL is the value you put in GENTOO_MIRRORS; the exact git / rsync sync URLs are in the tutorials below.

Configuration tutorials

① Sync the Portage tree over git (recommended)

Tested working git sources:

Mirror	Sync URL
Tsinghua TUNA	`https://mirrors.tuna.tsinghua.edu.cn/git/gentoo-portage.git`
USTC	`https://mirrors.ustc.edu.cn/gentoo.git`
ZJU	`https://mirrors.zju.edu.cn/git/gentoo-portage.git`
NJU	`https://mirrors.nju.edu.cn/git/gentoo-portage.git`
BFSU	`https://mirrors.bfsu.edu.cn/git/gentoo-portage.git`
SDU	`https://mirrors.sdu.edu.cn/git/gentoo-portage.git`
HUST	`https://mirrors.hust.edu.cn/git/gentoo-portage.git`
GitHub (overseas)	`https://github.com/gentoo-mirror/gentoo.git`

Switching to git sync for the first time: edit /etc/portage/repos.conf/gentoo.conf:

[gentoo]
location = /var/db/repos/gentoo
sync-type = git
sync-uri = https://mirrors.bfsu.edu.cn/git/gentoo-portage.git
auto-sync = yes

Remove the old rsync directory, then sync:

rm -rf /var/db/repos/gentoo
emerge --sync

Already on git, just changing mirrors: update the sync-uri above, then point the git remote at the new URL in the repo directory:

cd /var/db/repos/gentoo
git remote set-url origin <new sync-uri>
emerge --sync

② Sync the Portage tree over rsync

Quite a few mirrors only offer git / distfiles and don’t run rsync at all. The ones below have been tested to expose the gentoo-portage module, so they’re safe to use.

Mirror	Sync URL
Tsinghua TUNA	`rsync://mirrors.tuna.tsinghua.edu.cn/gentoo-portage`
USTC	`rsync://rsync.mirrors.ustc.edu.cn/gentoo-portage`
BFSU	`rsync://mirrors.bfsu.edu.cn/gentoo-portage`
NCHC (Taiwan)	`rsync://ftp.twaren.net/gentoo-portage`
PlanetUnix (Hong Kong)	`rsync://hippocamp.cn.ext.planetunix.net/gentoo-portage`

Edit /etc/portage/repos.conf/gentoo.conf and point sync-uri at any of the addresses above:

[gentoo]
location = /var/db/repos/gentoo
sync-type = rsync
sync-uri = rsync://mirrors.bfsu.edu.cn/gentoo-portage
auto-sync = yes

Then run emerge --sync.

③ Distfiles config (GENTOO_MIRRORS)

In /etc/portage/make.conf, fill in the distfiles URL from the overview table. You can list several (Portage tries them in order, with the earlier ones taking priority):

GENTOO_MIRRORS="https://mirrors.bfsu.edu.cn/gentoo https://mirrors.tuna.tsinghua.edu.cn/gentoo https://mirrors.ustc.edu.cn/gentoo"

Once both Portage and Distfiles are set up, run emerge --sync to update.
