Installation of JD K1 eight
I installed it directly through the following command:
1: Run the yum install command and wait for the installation
yum install -y java-1.8.0-openjdk-devel.x86_64
2: Check whether the installation is successful
Installing Rabbitmq
1: Enter the official website to view the version content
2: Go to github and download the corresponding rabbitmq installation package
Or download the installation package through wget
wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.16/rabbitmq-server-3.8.16-1.el8.noarch.rpm
3: Download erlang package
wget https://github.com/rabbitmq/erlang-rpm/releases/download/v24.0/erlang-24.0-1.el8.x86_64.rpm
4: Download socat package
https://repo.almalinux.org/almalinux/8.3-beta/AppStream/x86_64/os/Packages/socat-1.7.3.3-2.el8.x86_64.rpm
5: Install erlang, socat and rabbitmq server in sequence
yum install erlang-24.0-1.el8.x86_64.rpm
yum install socat-1.7.3.3-2.el8.x86_64.rpm
yum install rabbitmq-server-3.8.16-1.el8.noarch.rpm
Problems in installing erlang (not encountered, but mentioned by others):
6: Start service
service rabbitmq-server start
7: Open interface management tool
rabbitmq-plugins enable rabbitmq_management
8: The default account admin does not enable remote access, so the new account is authorized
#Add user
#./rabbitmqctl add_user account password
rabbitmqctl add_user admin admin
#Assign a user tag (admin is the name of the newly created account that you want to give administrator permission)
rabbitmqctl set_user_tags admin administrator
#Set permission < enable remote access > (if remote connection is required, such as calling mq in java project, it must be configured, otherwise it cannot be connected to mq. Admin is the name of the account just created to grant remote access permission, and rabbitmq must be run to execute this command)
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
Login successful
Then install the delay queue plug-in of rabbitmq, rabbitmq official website to view the installation content
You can still download with wget (after downloading, copy it to / usr/lib/rabbitmq/lib/rabbitmq_server-3.8.16/plugins directory, or directly wget in this folder):
wget https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/3.8.9/rabbitmq_delayed_message_exchange-3.8.9-0199d11c.ez
Launch plug-in
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
Enter view delay queue already exists (indicates success)
