Meeting with ubuntu forum admin -- WangPian ("oneleaf")

今天专程去东莞拜访 王翩 ("oneleaf"), http://forum.ubuntu.org.cn
的管理员,见到了他一家人(他有个非常可爱的儿子,只有三岁,机灵得什么都懂似的。) 听他谈了谈 ubuntu 站点的情况,也给 fedora
提出了不少建议。我给他 show 了下 SZLUG (深圳LUG) 上次聚会的照片。最后还从他那里顺走一件 Ubuntu 的 T 恤 :D
这一天真是收获太大了。

ubuntu 的站点情况如下:

12 万用户,95 万帖,目前处于上升期,绝对数量为 linuxsir 1/2
机器为自己组装,RMB ~14k
Xeon 4 核 x2 3.0 GHz 2M cache per CPU, load 60% (avg) ~80% (busy),
load ~28 (today max)
4GB ECC RAM
7200r 16M cache 300GB for root and mysql, may including repo, 40% usage (100GB)
7200r 16M cache 300GBx2 (raid 0) for www, may including ftp, 85% usage (525GB)
du -hs /var/lib/mysql: 5.1 GB (posts, fully indexed)
du -hs /var/lib/www: 40 GB (attachments)
bandwidth: 100M shared (东莞电信道滘), upper limit 5~8M, RMB ~4k/year, 2~3 次现场维护
traffic (today): repo 15G, www 40G, ftp 30G
proc:
* mysqld 135, 1G
* php-cgi 33, 2G(min)~2.5G(usually)
* lighttpd(forum, php) 9, 35k IP/day (max)

mantainance scripts: sys, mem, mysql, ps

给 fedora 的建议:

1. 必须有足够的原创文章,避免用户流失
2. 建立 wiki,与论坛实现 single sign on,也允许匿名更改
3. 建立主页,主页不要添加到论坛的入口
4. 有条件上 CDN,不选择国外,不选择双线
