Ubuntu学习之路还很长，做个笔记也不亏
terminal tab 补全忽略大小写：
在 /ect/inputrc文件中添加或修改 'set completion-ignore-case on'
Ubuntu 开机后关掉桌面（我是用来减轻虚拟机压力）：
/etc/defualt/grub : 'quick flash' 改为 'text' 重启。注：关掉桌面可能回不去。
可以用sudo startx 来启动桌面。（要启动桌面的话建议1G内存以上）

phpmyadmin config file: /etc/phpmyadmin/config.inc.php
$cfg['Servers'][$i]['table_uiprefs'] = 'pma_table_uiprefs';
改为: $cfg['Servers'][$i]['pma_table_uiprefs'] = 'pma_table_uiprefs';
win7关闭自动启动项：

mysql :
出现这个问题：
1 sudo invoke-rc.d mysql start Rather than invoking init scripts through /etc/init.d, use the service(8) utility,
e.g. service mysql start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility,
e.g. start mysql start: Job failed to start invoke-rc.d: initscript mysql, action "start" failed.
无法安装mysql-server，以及出现依赖问题，折腾许久，反正一下方法解决了我的问题，系统版本：ubuntu14.04
sudo apt-get remove --purge mysql-server mysql-client mysql-common sudo apt-get autoremove sudo apt-get autoclean
sudo apt-get install mysql-server-5.5 mysql-common mysql-server mysql-client
apache documentRoot 改写：
直接改写/etc/apache2/sites-enabled/000-default.conf 中的documentRoot 无效，可以用apachectl -S 来查看状态，但是好像并没用
1. 改写/etc/apache2/apache.conf
<Directory /var/www>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
=>
<Directory />
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
2. 改写/etc/apache2/sites-enabled/000-default.conf 的documentRoot
DocumentRoot /home/username/var/www
