MQTT之mosquitto_passwd命令使用

可以使用mosquitto自带的mosquitto_passwd命令生成密码文件。

mosquitto_passwd -c [最终生成的password_file文件] [用户名] 。

#: mosquitto_passwd -c passwd.conf jinhe_sub

输入命令后,控制台会提示输入新建用户的密码，连续输入两次密码后，则会生成一个passwd.conf文件。

注意,mosquitto_passwd -c命令每次都只会生成只包含一个用户的文件,如果你想在passwd.conf中存放多个用户，可以使用mosquitto_passwd -b 命令。

mosquitto_passwd -b [最终生成的password_file文件] [用户名] [密码]。

mosquitto_passwd -b命令必须在控制台输入明文的密码，且每次只是在passwd.conf中新增一个用户，不会覆盖之前已生成的用户。

同时也可以使用mosquitto_passwd -D命令删除一个用户。

更具体如下：

Name

mosquitto_passwd — manage password files for mosquitto

Synopsis

mosquitto_passwd [ -c | -D ] passwordfile username

mosquitto_passwd -b passwordfile username password

mosquitto_passwd -U passwordfile

Description

mosquitto_passwd is a tool for managing password files the mosquitto MQTT broker.

Usernames must not contain ":". Passwords are stored in a similar format to crypt(3).

Options

-b

Run in batch mode. This allows the password to be provided at the command line which can be convenient but should be used with care because the password will be visible on the command line and in command history.

-c

Create a new password file. If the file already exists, it will be overwritten.

-D

Delete the specified user from the password file.

-U

This option can be used to upgrade/convert a password file with plain text passwords into one using hashed passwords. It will modify the specified file. It does not detect whether passwords are already hashed, so using it on a password file that already contains hashed passwords will generate new hashes based on the old hashes and render the password file unusable.

passwordfile

The password file to modify.

username

The username to add/update/delete.

password

The password to use when in batch mode.

Examples

Add a user to a new password file:

mosquitto_passwd -c /etc/mosquitto/passwd ral

Delete a user from a password file

mosquitto_passwd -D /etc/mosquitto/passwd ral
