Minimum CentOS7 installation and subsequent software installation

It doesn't matter which package to download to install CentOS. the minimum installation is the same. If you want to configure the local yum source, you can download the everything installation package. The installation process should not be too simple. you can freely install the desktop environment on Baidu. the CentOS with the minimum installation does not provide the desktop environment, and many commands are different from the previous ones. so I rummaged over 6 on the Internet. X tutorials are basically useless. Here I installed Xfce4, and CentOS will be installed later.

The installation process should not be too simple.

Install the desktop environment

The minimal installation of CentOS does not provide a desktop environment, and a lot of commands are different from the previous ones. Therefore, it is basically useless for me to go online to a lot of 6. X tutorials.
Here I installed Xfce4, which will be used as a reference later. KED and Gnome are too big, and my book has a fever.
The procedure is as follows: 
Be sure to join! Be sure to connect to the Internet! Be sure to connect to the Internet! 
1. install additional yum sources

# yum install epel-release

2. install X Window System

# yum groupinstall "X Window System"

3. install Xfce4

# yum groupinstall Xfce

4. install Chinese fonts and input methods. skip this step if you are forced to read Chinese characters. However, it is possible that the Chinese characters on the webpage will become box characters, but the characters may be garbled or still show English characters.

# yum install cjkuni-ukai-fonts

I followed the tutorial and the eldest brother picked a simplified Chinese character with a very eye! My aesthetics have collapsed. In fact, the words in adobe's bag will be much better.

# yum search fonts

Select one you like. if you don't understand it, you can accept the following body and change it.

The input method is ibus pinyin on The ibus platform. (Well, there are input method platforms and input methods)

# yum install ibus# yum install ibus-libpinyin# yum install ibus-gtk2# yum install ibus-gtk3# yum install im-chooser# yum install gtk2-immodule-xim# yum install gtk3-immodule-xim

5. always have a bit of reverence to wash your hands. Run startxfce4 to enter the desktop. First visit the following and prepare for the second wave.

Install software

If you think that linux is too high under the command line, why do you need to see it here! Your hair-mounted desktop environment. Since we have installed the desktop, it is easy to give priority to it, and then we need to deploy the basic software. Otherwise, it would be useless to create a desktop. Because Xfce won't even give you a command line .!

If the graphic interface is not displayed at startup, do not worry. if the graphic interface is displayed at startup, exit. Wait for a while in the command line.

• Ctrl + alt + f1 enter the graphic interface
• Ctrl + alt + f2 ~ 6. enter the command line

The installation is simple and the effect is excellent. console: xfce-terminal is good 2. browser: Firefox and chrome. Firefox is recommended, because chrome must be configured with source 3 separately. compression software: file-roller 4. software Management: yum Extender 5. text Editing: gedit. if you already use vim (impossible), when I didn't say 6. sound card graphics driver, if you need

Then various development environments are built on your own. it's time to finish playing it. Ask Baidu about the specific installation command.

Problem summary

• All operations need to be connected to the internet. if you are not connected to the Internet, you need to configure local yum, but many software may not be available. If the yum connection times out, most of them are not connected to the Internet.
• If you are prompted that The NIC is not enabled, use the root account to edit/etc/sysconfig/network-script/ifcfg-$ Nic name, modify ONBOOT = yes
  • Vi/etc/sysconfig/network-script/ifcfg-$ Nic name
  • By I
  • Arrow keys control cursor modification
  • Press esc
  • Press colon x ": x"
  • Reboot
• If the desktop is not Chinese, you need to modify the configuration file. I simply re-installed it again. I first installed the language support and then installed the desktop. Without looking at the wiki carefully, I don't know what the problem is. it may be because I installed the language before I started the desktop for the first time. I started the desktop right away, so I don't know.
• If you do not enter the desktop after the boot, you can still use the command line. Runsystemctl set-default graphical.target. Then restart the instance.

• Install the software under the software package. Compared with win, it is really troublesome. if you can use yum, try to use it. Generally, extract the software and check the README or INSTALL file. the general installation is./configure,make,makeinstall. Other questions about Baidu are complicated and varied.
