* I.MX6 ubuntu-core-14.04 Apache php mysql Qt5
* 说明：
* 之前有尝试过12.04版本的，这里再继续尝试一下14.04，看一下有什么不同的

三、修改内容：
1. cat /etc/init/ttymxc.conf
# tty5 - getty
#
# This service maintains a getty on tty5 from the point the system is
# started until it is shut down again.
start on runlevel [23] and not-container
stop on runlevel [!2345]
respawn
exec /sbin/getty -L 115200 ttymxc0 vt102
2. cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto eth0
iface eth0 inet dhcp
hwaddress ether 70:B3:D5:10:6F:92
3. cat /etc/passwd

四、查看情况：
1. 网络：
root@localhost:/# ifconfig

2. 更新：
apt-get update
3. 安装mysql（已安装成功）：
apt-get install mysql-server
4. Vim：
apt-get install vim
5. 安装php5，结果自动安装了apache：
1. apt-get install php5
2. 上面命令自动安装了apache2
3. 解决报错：
1. localhost login: AH00557: apache2: apr_sockaddr_info_get() failed for localhost.localdomain
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
2. cat /etc/apache2/apache2.conf
......
ServerName <your server name> # 添加在最后，如果本身有这个字段，修改就OK了
6. 安装qt5-default：
1. apt-get install qt5-default
2. apt-get install make g++
3. 测试程序：http://zetcode.com/gui/qt5/widgets/
4. 编译脚本remake.sh：
#!/bin/bash
qmake -project
qmake
sleep 1
echo "QT += widgets" >> root.pro
make
7. 安装dbus
1. apt-get install dbus
2. apt-get install libegl1-mesa-dev
3. dbus-uuidgen > /var/lib/dbus/machine-id
