1. The change of desktop style
If you want to set the desktop style of
Centos7 and enter the desktop of Centos8 and find that the application icons cannot be displayed on the desktop, this is the default style change of the CentOS8 desktop. The default desktop of CentOS8 does not support desktop icons, only an empty desktop wallpaper, and After right-clicking, you can only open the settings, but not the terminal.
Gnome has 5 desktop versions when it starts. Centos7 defaults to classic (X11 display server), Centos8 defaults to standard (Wayland display server). So if we need to change the desktop version, after entering the account, we should not enter the password. Instead, click the gear icon next to login. Select Classic (X11 display server)/Classic (X11 display server) to place icons on the desktop.
The desktop startup method of the software is also different, Centos7 double-click the .desktop file, Trust and Launching, Centos8 is the right mouse button. Desktop file, Allow Launching
Two, set to support Chinese
Centos8 does not support Chinese
Centos 8.0 by default. It can now be used directly on Alibaba Cloud servers. The operation of the new system will be different, yum has been changed to dnf. The method to set the new version to support Chinese is as follows:
1. Update the system (optional to prevent installation failure), the update process is very slow, so it is recommended to skip
dnf upgrade
2. Check the currently installed locale
locale -a
3. By default, Alibaba Cloud does not install other language support. Here we need to install Chinese support ourselves, but note that the installation package of centos8 is no longer the same as centos7.
Install the zh-CN language package
dnf search langpacks
dnf -y install langpacks-zh_CN
/etc/locale.conf is the configuration file of the system's character set, modify it to Chinese, just source it, and then there will be a Chinese language pack on the language setting page in the system settings
vim /etc/locale.conf
改成这个：LANG=zh_CN.UTF-8
source /etc/locale.conf
4. After the installation is complete, execute locale -a again to check the language pack list and find that the Chinese language pack has been installed. After restarting, select the Chinese configuration of the classic (X11 display server) system to complete
3. A new generation of RPM package manager DNF
yum --> dnf
DNF is a new generation of RPM package manager, it overcomes some bottlenecks of YUM package manager, and improves many aspects including user experience, memory usage, dependency analysis, running speed and so on. Currently, CentOS7 and other versions do not have DNF installed by default, but you can install the dnf package manager by yum install dnf -y. It is highly recommended to use this instead of yum. Although the installation method of the software package has been changed, dnf is still compatible with the use of yum configuration files and commands. (The method of use is as simple as replacing yum with dnf)
