"2016-09-16" UbuntuServer14.04 or later installation issue record

For project needs, our QT program needs to run in

1. Windows/linux-x86 platform (CPU is a common desktop-level CPU such as G3220, I3, etc.);

2. Windows/linux-x86 Low-Power platform (CPU is Intel Atom processor, such as AtomN2600, etc.);

3. Embedded Arm platform (CPU is arm Cortex A8 or higher), etc.

Currently, the Windows, Embedded Arm, Linux desktop Release (Ubuntu) platform has been successfully run, and the Linux system platform should be completely free of problems.

To conserve system resources, we plan to use Ubuntu server instead of the Ubuntu desktop distribution on the X86 universal platform and low-power platforms, as compared to the Ubuntu desktop version, the server version is lighter, And then you can customize, install some necessary software to implement the desktop version of the operation.

The primary difference between Ubuntu server and Ubuntu Desktop is that the server version does not have a GUI, but it can be installed on its own.

To summarize, the difference between Ubuntu Server Edition and Desktop Edition is mainly:

A. Desktop edition is usually configured for personal computers, while Server Edition is suitable for Web servers;

B. The desktop version is preinstalled with the GUI, and the server edition is not;

C. Desktop version has installed a number of server version of the software is not;

D. The desktop version is missing Apache, MySQL, and PHP, which are standard in the server edition.

We plan to install Ubuntuserver14.04lts on the X86 universal platform and low power platforms, and then install the GUI as needed.

System installation method No outside of the CD-ROM installation, U disk installation and so on, we use some common U disk installation tools to make the installation disk.

First, how to install Ubuntu server using USB flash drive to resolve the installation termination caused by checking CDROM failure

Now we are basically using a USB stick to install Windows or Linux operating system, generally through the old peaches, cabbage and other production startup disk, the ISO package can be put in.

Such a way to install Ubuntu Desktop version is no problem;

However , when installing Ubuntu server using the U-disk, the installation must be terminated shortly after booting the installation due to a failure to detect the CD Rom:

Even if you choose Retry, you cannot succeed.

If you search Ubuntu server CDROM, you may get a variety of workarounds, such as:

A. Skipping cdrom detection, using USB detection

When you select the menu of the installation interface, press Help, then F6 the custom machine, enter

Installcdrom-detect/try-usb=true

Enter the installation

B. Manually mount the CDROM

Press the ALT+F2 key to bring up the command screen first

#查看u盘盘符信息, this is SDB.

Fdisk-l

#挂载u盘到/mnt Directory

Mount/dev/sdb/mnt

#挂载iso镜像文件到/cdrom Directory

Mount/mnt/ubuntu-14.04.4-server-i386.iso/cdrom

#查看 the/cdrom directory to determine if the mount was successful

Finally exit the command screen, press ALT+F1, select OK to start the installation

and other methods;

Solve:

However, some of these methods are only suitable for previous versions, such as method A may be available for version 10.04, but not usable in version 12.04 or later;

and method B, such as manual mounting, for our parallel imports, the operation is still not easy ah.

In fact, the simplest way:

is to use the old peaches and so on to make the installation disk, but using such as Image Writer (also known as Win32diskimager) or Ubuntu under the UNetbootin (need to install) to make the boot disk.

For example, I use image Writer to ubuntu-14.04.4-server-i386. The ISO is written to the U-disk, thereby serving as the installation disk;

Of course, this approach also has flaws:

The entire U-disk is no longer available under window unless formatted;

And with the old Peaches to do the installation disk, in addition to the mirror occupied space, we can still be used as ordinary u disk.

Sure enough, you can only expect Ubuntu server to not detect CDROM when it is installed.
