这个没有加上禁用cache，容易出现修改代码chrome不去读取：
#!/bin/bash export DISPLAY=:0.0 PROCESS_NUM=`ps -ef | grep "chromium-sandbox" | grep -v "grep" | wc -l` if [ $PROCESS_NUM -eq 0 ]; then         chromium-browser --kiosk  "http://192.168.2.2/" fi

/usr/local/scripts/restartChrome.sh
#!/bin/sh export DISPLAY=:0.0 ps -fe|grep chromium|grep -v grep if [ $? -ne 0 ] then chromium-browser --kiosk --disk-cache-dir=/dev/null  "http://localhost/index.html?name=jack&rand={$RANDOM}" echo "start process....." else echo "runing....." fi #####

再次对第一个的代码修正：
#!/bin/bash export DISPLAY=:0.0 PROCESS_NUM=`ps -ef | grep "chromium-sandbox" | grep -v "grep" | wc -l` if [ $PROCESS_NUM -eq 0 ]; then         chromium-browser --kiosk --disk-cache-dir=/dev/null "http://192.168.2.2?rand={$RANDOM}" fi

在那个pi用户下，crontab -e
10秒启动一次：
* * * * * /usr/local/scripts/restartChrome.sh >/dev/null  
* * * * * sleep 10; /usr/local/scripts/restartChrome.sh >/dev/null  
* * * * * sleep 20; /usr/local/scripts/restartChrome.sh >/dev/null  
* * * * * sleep 30; /usr/local/scripts/restartChrome.sh >/dev/null  
* * * * * sleep 40; /usr/local/scripts/restartChrome.sh >/dev/null  
* * * * * sleep 50; /usr/local/scripts/restartChrome.sh >/dev/null  

简介：
Solution of how to disable Cache in Chromimum browser.
转载请注明出处。


There's an option which does not appear in chromium's manual page --- "-disk-cache-dir".
This option specifies where the disk cache should be stored.
Hence, under Linux, we can set the disk-cache-dir to /dev/null. In that way, the cache will be disabled, and all contents will be read from the Internet directly.

Here is what the modified chromium-browser-chromium.desktop looks like:
[Desktop  Entry]
Name=Chromium Type=Application
Comment=Open-source version of Google Chrome web  browser
Exec=chromium-browser %U --disk-cache-dir=/dev/null 2>/dev/null
TryExec=chromium-browser
Icon=chromium-browser
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;x-scheme-handler/http;x-scheme-handler/https;  


Why I need to disable file cache?
Well, on my machine, when chromium browser starts up, it keeps reading cache and take a long time to show the homepage.
So I decided to disable it.
