Three important things before Ubuntu Installation

Although the installation of Ubuntu is much simpler and requires no professional knowledge, three important things need to be done before installation. Plan whether the disk really needs Ubuntu backup data. Remember that when I first installed Linux, data is often lost due to some errors. If you are not sure whether to make mistakes, or you cannot ensure that there is no human force majeure problem during the installation process (this is a bit sweaty ~~), Back up data before installing the system. The following section describes four common backup data types:

Back up data

I remember that when I first installed Linux, data is often lost due to some errors. If you are not sure whether to make mistakes, or you cannot ensure that there is no human force majeure problem during the installation process (this is a bit sweaty ~~), Back up data before installing the system.

The following are four common methods for data backup:

• Back up data to the cloud. The term "Cloud" is only available now. Traditionally, It is online backup and backup to the Internet. Now many online disks can provide you with good services, such as Dropbox, Box.net, in China, there are 115 and dbank, which can be selected based on the actual situation.
• Back up data to a mobile hard disk. This method is much more convenient than the first one, but it is not just a peripheral that you can use to back up data. Generally, the local disk may store a large volume of things.
• Burn to a CD. This method is relatively old, and many people do not need it now, but it is also a method, especially when the conditions are just suitable.
• Back up data to another partition. Compared with the above three, this is the simplest and most quick, so you have to plan your partition and separate some hard disks to store data.

It is strongly recommended that you back up data before installing the system. This is a good habit and it will be good if you have good data management habits.

Plan Disks

Disk planning may be simple for veterans, but it is a headache for new users. For Ubuntu installation, the official website provides detailed guidance documents, but many people do not have the habit of reading the official guide. When the CD is available, they start to ask questions everywhere, in fact, many questions are described in detail in the official guide. Of course, there are a lot of official guidance content that is cool and tedious, but it is still a good habit for beginners to have a complete reading reference.

Let's get down to the truth and continue to talk about the disk planning problem. Generally, Linux installation requires the following three partitions:

• Root partition (/). This is also called the root partition. The entire system will be installed in this partition.
• User partition (/home ). Used to store related files for each user.
• Swap partition (swap ). The simple explanation is equivalent to the virtual memory in Windows. It is recommended that swap partitions be configured for machines with larger memory.

Let's talk about the capacity required for the above three partitions:

• Root partition. This is used to install the system, so you can refer to the official instructions of the specific system. Generally, to install a complete Linux Desktop System, the 4G capacity is more than enough, of course, the installation of application software will occupy more space in the future.
• User partition. This is used to store specific user files and can be allocated as needed.
• Swap partition. The earliest statement was that we recommend that you double the actual memory size. However, with the development of the current hardware, we usually have 2 GB of memory. If swap has 4 GB memory, it seems a waste, therefore, we recommend that you use 1g or 2G.

After talking about this, how can we plan disks?

The following figure shows four partition schemes:

Only install Linux

Only install Linux and have independent data storage partitions

Coexistence of linux and windows systems

Linux is a Windows system with independent data storage partitions.

Specific partitioning operations can be performed before installing the system, using a familiar disk management tool for partitioning, or performing partitioning operations during system installation.

Do you really need Ubuntu?

Why Ubuntu? Ubuntu is a popular among many Linux distributions, with a large user base and good community support. Of course, it is not your only choice, and other Linux releases are also very good, such as Fedora, LinuxMint, OpenSUSE and Archinux .. I am using Archlinux

Why not select another one? Of course, you can also choose other Linux distributions. Nowadays, many Linux distributions provide LiveCD, which can be used directly to guide the system without being installed on the hard disk. You can use LiveCD to try multiple systems, and then select a suitable one based on your own experience and computer conditions.

Other reasons? If you still use a low-configuration computer, Ubuntu may not be the best choice. The minimum recommended configuration is as follows:

• Graphics card
• 512 memory
• 4 GB disk space remaining

If your "old man" cannot meet the above conditions, you can select the following lightweight release editions:

• Lubuntu
• LMDE
• Pubby linux
• ArchBang

 

Three Advantages and three disadvantages of Ubuntu are as follows:

Advantages:

1. It is one of the most popular linux distributions. You can find many forums or blogs about it.
2. It is an out-of-the-box system. You do not need to use various command lines in Termianl to configure the system. Many operations can be done through visual programs.
3. There are many user guides on the Internet. You can find answers to many questions you encounter during use for your reference.

Disadvantages:

1. It is not the most stable Linux release.
2. It is not the most lightweight or fastest Linux release.
3. You may be sprayed by other Linux release users, * pai_^ *
