Linux下三种便捷的密码生成器

pwgen

makepasswd

passwdmaker

注：目前仅尝试了pwgen和makepasswd，但是目前仅pwgen成功。

=================================================================

以下是安装过程

yum安装,报错

sudo yum install makepasswd

[root@iZ2zeczh9tfpmxmijw5qppZ java]# yum install makepasswd
Loaded plugins: fastestmirror

 * updates: mirrors.aliyuncs.com
No package makepasswd available.
Error: Nothing to do
[root@iZ2zeczh9tfpmxmijw5qppZ java]#

经查询之后进行yum的扩展和更新：

yum install epel-release //扩展包更新包

yum update //更新yum源

yum repolist //确定更新结果正常

但是安装makepasswd时依旧报错，

转而进行安装pwgen，

yum installpwgen

结果正常
