How to install vim on centos

How to install vim in centos?

When using vim in a Linux environment, the prompt: vim command not found means that vim has not been installed on the system.

Installation steps:

1. Check whether it is installed

Check the packages that already exist on your machine and confirm whether your VIM has been installed. Enter:

rpm -qa|grep vim

If it has been installed, it will be displayed:

[root@localhost usr]# rpm -qa|grep vim
vim-minimal-7.4.629-6.el7.x86_64
vim-filesystem-7.4.629-6.el7.x86_64
vim-enhanced-7.4.629-6.el7.x86_64
vim-common-7.4.629-6.el7.x86_64
vim-X11-7.4.629-6.el7.x86_64

2. Installation

If one of them is missing, for example: the vim-enhanced package is missing, then execute:

yum -y install vim-enhanced

It will automatically download and install. If none of the above three packages are displayed, enter the command directly:

yum -y install vim*

It will be installed automatically after executing the command. After completion, you can use the vim editor.

3. Configuration

After the installation is complete, start configuring vim

vim /etc/vimrc

After opening the file, press i to enter the edit mode, and then find a location to add the following code

 set nu          " 设置显示行号
 set showmode    " 设置在命令行界面最下面显示当前模式等
 set ruler       " 在右下角显示光标所在的行数等信息
 set autoindent  " 设置每次单击Enter键后，光标移动到下一行时与上一行的起始字符对齐
 syntax on       " 即设置语法检测，当编辑C或者Shell脚本时，关键字会用特殊颜色显示

After adding, press Esc, then enter

:wq

to exit and save.
