linux 批量创建用户

user 模块添加用户

python -c 'from passlib.hash import sha512_crypt; import  getpass;  print (sha512_crypt.encrypt(getpass.getpass()))'    #python3 生成密码

ansible all -m user -a "name=admin password=$Mf6OK/7vjBDxZbjo$6Nj10h0Oa1fEoULbObgVcVWMT1XwCBR home=/app/admin createhome=yes"        #使用user模块创建用户

cat /etc/shadow | grep admin                             #查看用户的密码

cat /etc/passwd |cut -f 1 -d :|grep admin            #查看某个用户是否存在
