The cause of the fault
was resolved on December 23, 2020. The cause of the /etc/profilealias alias vim='/usr/bin/vi, there is an alias in the file , that is, the vim command actually uses vi

Solution
to /etc/profilefile alias vim='/usr/bin/vichange alias vim='/usr/bin/vimcan be.

Here are the solutions to other problems
. The VI in Centos only installs vim-minimal-7.x by default. No matter you enter vi or vim to view the file, the syntax function cannot be enabled normally. Therefore, two other components need to be installed with yum: vim-common-7.x and vim-enhanced-7.x.

#View vim components
[root@client1 ~]# rpm -qa | grep vim
vim-enhanced-7.4.629-7.el7.x86_64
vim-filesystem-7.4.629-7.el7.x86_64
vim-X11-7.4.629-7.el7.x86_64
vim-common-7.4.629-7.el7.x86_64
vim-minimal-7.4.629-7.el7.x86_64

#install vim
yum -y install vim*
