-Bash: vim: command not found appears in vim.

When a centos host is used,-bash: vim: command not found occurs when vim is used. Only vi can be used. How can we install vim?
Enter the rpm-qa | grep vim command. If vim is correctly installed, the following three lines of code are returned:
[Root @ centos] # rpm-qa | grep vim
Vim-minimal-7.0.109-6.el5
Vim-common-7.0.109-7.2.el5
Vim-enhanced-7.0.109-7.2.el5

If one of them is missing, such as vim-enhanced, run the yum-y install vim-enhanced command to install it:
Yum-y install vim-enhanced
If none of the above three results are returned, you can directly use the yum-y install vim * command.
