Access Dashboard with HTTPS

SpringBoot itself has provided the SSL configuration. You can use the project test Keystore:resources/rmqcngkeystore.jks. The store is generated with the following unix keytool commands:

#Generate Keystore and add alias rmqcngKey
keytool -genkeypair -alias rmqcngKey  -keyalg RSA -validity 3650 -keystore rmqcngkeystore.jks 
#View keystore content
keytool -list -v -keystore rmqcngkeystore.jks 
#Transfer type as official 
keytool -importkeystore -srckeystore rmqcngkeystore.jks -destkeystore rmqcngkeystore.jks -deststoretype pkcs12

Uncomment the following SSL properties in resources/application.properties. restart Dashboard then access with HTTPS.

#Set https port
server.port=8443

### SSL setting
server.ssl.key-store=classpath:rmqcngkeystore.jks
server.ssl.key-store-password=rocketmq
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=rmqcngkey

Access Dashboard with username and password and logout to leave the dashboard。To stage the function on, we need the steps below:

1.Turn on the property in resources/application.properties.

# open the login func
rocketmq.config.loginRequired=true

# Directory of ashboard & login user configure file 
rocketmq.config.dataPath=/tmp/rocketmq-console/data

2.Make sure the directory defined in property ${rocketmq.config.dataPath} exists and the file "users.properties" is created under it. The dashboard system will use the resources/users.properties by default if a customized file is not found。

The format in the content of users.properties:

# This file supports hot change, any change will be auto-reloaded without Console restarting.
# Format: a user per line, username=password[,N] #N is optional, 0 (Normal User); 1 (Admin)

# Define Admin
admin=admin,1

# Define Normal users
user1=user1
user2=user2

3.Restart Console Application after above configuration setting well.

Permission Control

If the login function is enabled when a user accesses the Console, the user controls the access permission of the interface based on the login role.

1.Turn on the property in resources/application.properties.

# open the login func
rocketmq.config.loginRequired=true

# Directory of ashboard & login user configure file 
rocketmq.config.dataPath=/tmp/rocketmq-console/data

2.Make sure the directory defined in property ${rocketmq.config.dataPath} exists and the permission control file "role-permission.yml" is created under it. The console system will use the resources/role-permission.yml by default if a customized file is not found。

The format in the content of role-permission.yml:

# This file supports hot change, any change will be auto-reloaded without Console restarting.
# Format: To add or delete interface permissions, add or delete interface addresses from the list.
# the interface paths can be configured with wildcard characters.
# ?: Matches 1 characters.
# *: Matches 0 or more characters that are not /.
# **: Matches 0 or more characters.

rolePerms:
  # ordinary user
  ordinary:
    - /rocketmq/nsaddr
    - /ops/*
    - /dashboard/**
    - /topic/*.query
    - /topic/sendTopicMessage.do
    - /producer/*.query
    - /message/*
    - /messageTrace/*
    - /monitor/*
    ....

3.On the front page, operation buttons such as deleting and updating resources are not displayed for common users in order to better distinguish the rights of common users and admin users. If need to operate related resources, log out and use the admin role to log in
