Setting up a virtual host on PC, Mac or Linux isn’t difficult, but the browser cache problem drives me crazy. Apart from editing the /etc/hosts mappings and httpd.conf, you need to restart both Apache and browser. Refreshing the browser(Firefox) doesn’t clean the cache, so the result will be always add /xampp/index.php at the end of [...]

安装ubuntu / Kubuntu的时候可以选择有程序自己分区或者自定义分区。一般来说Linux的分区可以有以下几个: /boot 操作系统启动文件分区，一般分配大小在250MB-500MB左右 /usr 操作系存放软件的地方 /bin 存放标准系统实用程序 /home 是用户的home目录所在地，多用户需要分配这个分区。比如用户andrew的目录会 被分配在 /home/andrew下面，而jay的目录会被分在/home/jay /tmp 用来存放一些临时文件的分区。 /var/log 系统日志记录分区，建立这个分区，即使日志文件出现了问题，也不会影响到操 作系统的主分区 /srv 服务器启动的数据存放在这里 /opt 大程序，可选择安装的程序存放在这里 / 根目录 /opt分区易于管理程序(备份LumaQQ为例): 重装linux的时候，选择自定义分区时不用格式化/opt分区，先备份好XXX/lumaqq文件夹，重装系统后，把lumaqq文件夹放回到XXX目录，配好java环境输入命令: $ sudo ln -s /opt/LumaQQ /usr/bin/lumaqq * ln – make new links to existing files 分区的顺序： 没有必要完全按照这个顺序，按照分区用途和硬盘结构来说，越靠近外边的效率越高，比如说/boot和swap是系统读取数据最平凡的分区，建议的顺序是: /boot -> SWAP -> /home -> /var/log -> /tmp -> /srv -> [...]
