1.Linux下python创建username源码

[root@njmon python]# cat create_user.py 
#!/usr/bin/env python
import os
import re
def create_user_func(username,password):
    with open('/etc/passwd', 'r') as fd:
        for line in fd:
            matchusername = re.search(r'%s' % username, line, re.I)
    if not matchusername:
        os.system('useradd -M -s /sbin/nologin %s -p %s' % (username,password))
        print('%s is create successfully' % username)
    else:
        print('%s is already exists.' % username)

def main():
    create_user_func('mysql','wwwwww')

if __name__ == "__main__":
    main()

2.创建mysql用户http://www.cndba.cn/hbhe0316/article/106599http://www.cndba.cn/hbhe0316/article/106599http://www.cndba.cn/hbhe0316/article/106599

[root@njmon python]# python create_user.py 
mysql is create successfully

3.当mysql用户存在的时候http://www.cndba.cn/hbhe0316/article/106599http://www.cndba.cn/hbhe0316/article/106599

[root@njmon python]# python create_user.py 
mysql is already exists.
