      liunx用户环境初始化脚本

编写生成脚本基本格式,包括作者,联系方式,版本,时间,描述等

[root@magedu ~]# vim .vimrc set ignorecase set cursorline set autoindent autocmd BufNewFile *.sh exec ":call SetTitle()" func SetTitle()         if expand("%:e") == 'sh'         call setline(1,"#!/bin/bash")          call setline(2,"#")          call setline(3,"#********************************************************************")          call setline(4,"#Author:                w")          call setline(5,"#QQ:                    1****")          call setline(6,"#Date:                  ".strftime("%Y-%m-%d")) 
        call setline(7,"#FileName:             ".expand("%"))         call setline(8,"#URL:                   http://www.magedu.com")         call setline(9,"#Description:          The test script")          call setline(10,"#Copyright (C):        ".strftime("%Y")." All rights reserved")         call setline(11,"#********************************************************************")          call setline(12,"")          endif endfunc autocmd BufNewFile * normal G   

编写用户的环境初始化脚本reset.sh,包括别名,登录提示符, vim的设置,环境变量,取OS版本号,网卡名更改,seliunx关闭等:

[09:26:08 root@centos ~]#vim reset.sh                               
  1 #!/bin/bash
  2 #

 12 CS="\033[1;$[RANDOM%7+31]m"
 13 CE="\033[0m"   
   
   这儿是定义了一些别名登陆时自动启用的,还有就是登陆提示符。
 14 cat > /etc/profile.d/env.sh << EOF
 15 alias cdnet="cd /etc/sysconfig/network-scripts"
 16 alias editnet="vim /etc/sysconfig/network-scripts/ifcfg-ens33"
 17 export PS1="[\[\e[32m\]\u\[\e[36m\]@\h_v7\[\e[31m\]\[\e[0m\] \w]\\$ "
 18 export PATH=/app/bin:$PATH
 19 EOF
 20 
 21 cat > ~/.vimrc << EOF
 22 set nu
 23 EOF  
   

 24 #取os版本号
 25 VER=`sed -rn 's@^.* ([0-9]+)\..*@\1@p' /etc/redhat-release`  

 26 #修改centos7,8网卡名为传统网卡名
 27 if [ $VER -ge 7 ];then
 28         sed -ir '/GRUB_CMDLINE_LINUX/s@"$@ net.ifnames=0"@' /etc/default/grub
 29         grub2-mkconfig -o /etc/grub2.cfg
 30 fi    

 这个是更改selinux启用和关闭
 31 #Disable selinux
 32 sed -i 's@^SELINUX=enforcing@SELINUX=disabled@p' /etc/selinux/config
