But currently we use the vim editor more often . Vim has the ability of program editing, can actively distinguish the correctness of grammar by font color, which is convenient for program design. ——Source : Introduction to runoob Linux vi/vim

One, install vim

First, see if vim is installed on this machine: enter the rpm -qa|grep vim command,

root@server1 [~] # rpm -qa|grep vim

If vim has been installed correctly, the following three lines of code will be returned:

vim-enhanced-7.0.109-7.el5
vim-minimal-7.0.109-7.el5
vim-common-7.0.109-7.el5

If one of them is missing, such as vim-enhanced, use the command yum -y install vim-enhanced to install:

yum -y  install  vim-enhanced

If none of the above three items are returned, you can directly use the yum -y install vim* command

yum -y  install  vim*
