我的例子： UPDATE `t_photos` SET nom_photo= CASE WHEN nom_photo REGEXP '[^_]*.png' THEN CONCAT('old/', REPLACE(nom_photo, '.png','.tif')) END WHERE nom_photo REGEXP '[^_]*.png' 替换前的内容是： 508e652bf1781.png 替换后的内容是： old/508e652bf1781.tif

 netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}' 查看 某个端口 netstat -n|grep -i time_wait|grep 127.0.0.1:9000|wc -l 查看mysql的连接数 netstat -n|grep -i time_wait|grep 3306|wc -l  

for file in /data/admin/web/data/vivastreet/image/50b7814*; do newname=`basename "$file" png`tif; convert $file -define tiff:tile-geometry=256x256 -compress jpeg "ptif:/mnt/data/vivastreet/$newname"; done well, this will rename the *.png to *.tif and convert them . further more, if you wann only list 100 file in a folder: ls | head -n 100 if you wanna to remove them: ls | head -n 100 | xargs rm

I find a good tutorial and this may be useful lately. http://www.howtoforge.com/how-to-set-up-a-caching-reverse-proxy-with-squid-2.6-on-debian-etch the important is do not cache the login user page, but only cache the anonimouse users page. This is alos ok for spoop.fr.

this article is a memo for the installation of webmin and his plugin, vitual sever. ubuntu 12.04 lts is really simple, just download his deb distribution by : cd /tmp wget http://prdownloads.sourceforge.net/webadmin/webmin_1.620_all.deb dpkg --install webmin_1.620_all.deb if have some package problem, just do: apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python for sure. you can read this ; http://www.webmin.com/deb.html then vitual min: cd /tmp wget http://software.virtualmin.com/gpl/scripts/install.sh chmod 775 install.sh ./install.sh and then yes ,yes,yes. 最后有个问题： /etc/apache2/apache2.conf 里面没有包含 NameVirtualHost *:80 但是没有它我原来的vhost在ubuntu 从12.04升级到12.10以后就都不行了， 还有就是必须先stop webmin， 重新启动apache2， 然后再启动webmin，所有的vhost都ok了。

主要根据这篇文章， https://admin-serv.net/blog/141/changer-le-reverse-de-son-dedie/ 更改 reverse name: grep -rin ns2301914 ./* 输出： grep: ./blkid.tab: No such file or directory ./hostname:1:ns2301914.ovh.net ./hosts:4:5.135.137.158         ns2301914.ovh.net       ns2301914 ./hosts:5:2001:41D0:8:CA9e::1   ns2301914.ovh.net       ns2301914 ./issue:2:Linux ns2301914.ovh.net 3.2.13-grsec-xxxx-grs-ipv6-64 #1 SMP Thu Mar 29 09:48:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ./issue:6:hostname  : ns2301914.ovh.net ./mailname:1:ns2301914.ovh.net ./motd:7:hostname  : ns2301914.ovh.net 更改所有的这些文件，把ns2301914.ovh.net 改成 spoop.ovh.net hostname spoop.ovh.net rndc flush /etc/init.d/bind9 restart 有一点需要注意： Vous devez tout d'abord avoir un champ A pointant vers l'adresse IP du dédié en question.

ovh自己的kernal build 和nfs 不兼容，有人如此说； Donc en fait c'est un problème sur Ubuntu (et peut être d'autres) entre le script de démarrage du serveur NFS et le kernel OVH. Il faut donc faire une modif du script de démarrage : Code: nano +67 /etc/init.d/nfs-kernel-server Commenter cette ligne: Code: if [ -f /proc/kallsyms ] && ! grep -qE ' nfsd_serv ' /proc/kallsyms; then Et la remplacer par: Code: if [ -f /proc/kallsyms ] && ! grep -qE 'init_nf(sd| )' /proc/kallsyms; then Après faire un Code: /etc/init.d/nfs-kernel-server/start 还有就是重装kernal： 详见： http://limeskystudios.com/articles/mise-en-place-dun-serveur-nfs-ubuntu 安装nfs server 请见： https://help.ubuntu.com/community/SettingUpNFSHowTo

sudo apt-get install backuppc =>save the user name and password. then you set up the config by cgi: http://backup-server/backuppc/ if your appache is started correctly. if backup linux, we use rsync for ssh tunnel.

Which will greatly increase the execution speed.
