debian的主要镜像是要满足一定条件的才能当,咱们的镜像满足了这些条件,所以申请了成功了。而次级镜像就不一定满足这些条件了。
从
https://www.debian.org/mirror/official 这个网页找到的主要镜像需要满足的条件:
To become an official mirror, a Debian mirror site
should meet the following criteria:
- The mirror should be registered (using our mirror
submission form).
- The site should be reliable and be up 24 hours a day. The machine should
not be heavily loaded.
- It should have a decent connectivity (relative to the respective country).
Bandwidth equivalent to a 100Mbps connection or better is preferred;
note that for developed countries, this minimum is much higher.
- The routers in front of the server shouldn't have any global
access bans or major limitations of bandwidth.
- The server needs to be able to sustain the traffic, i.e. have
reasonable limits on the HTTP, FTP and rsync daemons, including
tuning the maximum number of connections in general and the maximum
number of connections from a single IP.
- Disk space commitments (with room for expansion) — see the
mirror size page.
- The whole Debian archive should be mirrored.
- The mirror hierarchy should be available under /debian.
Rationale: for consistency between sites — you may simply
place a symlink if you want to keep the mirror somewhere else, or
set up a virtual host.
- The mirror should be made available at least via these protocols:
- HTTP (http://your.server/debian/)
HTTP is used because with HTTP/1.1 transfers have the
potential of being more efficient than with FTP.
- FTP (ftp://your.server/debian/)
FTP is the most senior protocol, and still very widely used.
- rsync (rsync://your.server::debian/)
Rsync is the preferred method of mirroring, and one of
the main functions of an official mirror is to help the
proliferation of secondary mirrors.
- The mirror should be updated with ftpsync,
a script which provides many required functions.
- Push mirroring needs to be set up; feel free
to contact us to get in touch with the maintainer of another mirror.
满足了上述条件才能是官方源(主要镜像)。像163这些源是不一定满足这些条件的。
加粗的内容是个人认为重要的内容,是区别与其他次级镜像的主要标志。像163、shou这些源当年就没有rsync,也没有push mirroring,所以说它们没有获得
ftp.cn.debian.org的域名,而且debian官方也没有把它们算作“offical mirror”,不过在“secondary mirror”列表里面还是有它们的。
我个人只是对debian的情况比较熟,所以我发了这封邮件问问所有源的情况。而且大家也看到了,咱们mirrors作为官方源在debian的地位也是不低的,所以说我想问其他镜像的情况,有哪些是一样情况在官方地位不低的,有哪些是官方源但是地位一般的,有哪些是为了自己方便而不是官方源的。这个还是要详细了解一下。
