需求：在L7的一台机器上做nginx配置，然后代码分发到别的所有的机器上。由于目录中有很多配置文件，而且防止误操作，需要修改配置之前先备份原配置。然后需要在运行修改配置的脚本之前，先弹出界面，告知操作哪一个脚本
python脚本
#!/user/bin/env python
import glob
import os
file = glob.glob("/home/work/nginx/site-enable/*.conf")
num = len(file)
for i in range(1, num+1):
print "%d. %s" %(i, file[i-1])
choose = int(raw_input('Enter your choose:'))
if(choose>0) and (choose<num+1):
file1 = file[choose-1].split('/')
num1 = len(file1)
filename = file1[num1-1]
os.system("sh /root/cpconf.sh %s" %filename)
else:
print "Input error!"
exit()
shell脚本：
#!/bin/bash
Date=`date +%Y%m%d%H%M`
cp /home/work/nginx/site-enable/$1 /home/work/opdir/nginx_bak/$1.$Date
cp /home/work/nginx/conf/$1 /home/work/opdir/nginx_bak/$1.$Date
cp /home/work/nginx/site-enable/$1 /root/
vim $1
echo -ne "\n\n########### diff conf ###############\n\n"
diff $1 /home/work/opdir/nginx_bak/$1.$Date
