 $ wget 
http://cronolog.org/download/cronolog-1.6.2.tar.gz
$ tar xvzf cronolog-1.6.2.tar.gz
$ cd cronolog-1.6.2
$ ./configure --prefix=/usr/local
$ make
$ sudo make install

----------------------------------------------------------------------------- 檢視裝在哪兒了（which也要sudo許可權那）： which cronolog 簡單測試 $ echo "This is a test." | /usr/bin/cronolog -o /var/log/www/%Y/access.%m-%d-%y.log "-o" 命令才能建立檔案 不加的話報錯 ok！ 為自己的web server編寫自啟動程式 沒有副檔名的指令碼檔案cam-hello : -----------------------------------------------------------------------------

----------------------------------------------------------------------------- --make-pidfile 才能建立自啟動檔案，被網上不完善程式誤導，導致只能啟動不能停止服務 ==！ python指令碼需更改為可執行檔案 不然無法執行 日誌檔案有個緩衝，達到一定長度才能寫入，很無語（實驗時候還以為python不能這麼弄。。。。） 部署自啟動程式 拷貝到 /etc/rc.d/init.d/ 修改指令碼檔案chmod 777 cam-hello 註冊： /etc/init.d# sudo update-rc.d cam defaults 如果要刪除start/stop links 則： sudo update-rc.d -f cam remove （注： chkconfig --add autoruntest 新增服務 這個命令有錯，不用它！ There is a loop between service apache2 and rsyslog if stopped） 部署成功後

/etc/init.d/cam-hello start
/etc/init.d/cam-hello restart
/etc/init.d/cam-hello stop
