RabbitMQ service installation and configuration in CentOS7

RabbitMQ service installation and configuration in CentOS7

RabbitMQ is a popular open-source Message Queue System and is a standard implementation of AMQP (Advanced Message Queuing Protocol Advanced Message Queue Protocol). It is developed in erlang language. RabbitMQ is said to have good performance and timeliness. It also supports cluster and load deployment and is very suitable for use in large-scale distributed systems. The specific features are still being verified, to be tested. As required by the project, RabbitMQ is installed and configured, and the server operating system is CentOS7. The procedure is as follows:

Install the dependency file:

Yum install gcc glibc-devel make ncurses-devel openssl-devel xmlto

1. Erlang installation Configuration

Download the installation package at http://www.erlang.org/downloads. I chose otp_src_18.3.tar.gz.

Decompress the file:

[Root @ iZ25e3bt9a6Z rabbitmq] # tar-xzvf otp_src_18.3.tar.gz
[Root @ iZ25e3bt9a6Z rabbitmq] # cd otp_src_18.3/

Configure the installation path to compile the Code:

[Root @ iZ25e3bt9a6Z otp_src_18.3] #./configure -- prefix =/opt/erlang

Execute the compilation result:

[Root @ iZ25e3bt9a6Z otp_src_18.3] # make & make install

After the execution is complete, go to/opt/erlang to view the execution result.

[Root @ iZ25e3bt9a6Z rabbitmq] # cd/opt/erlang/
[Root @ iZ25e3bt9a6Z erlang] # erl
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp: 8: 8] [async-threads: 10] [hipe] [kernel-poll: false]

Eshell V7.3 (abort with ^ G)
1>

If the preceding information is displayed, the installation is complete. Enter 'halt (). 'to exit.

Then, add the following environment variables in the configuration of the Erlang environment variable vi/etc/profile file:

# Set erlang environment
Export PATH = $ PATH:/opt/erlang/bin

Source/etc/profile to make the file take effect

During Erlang installation, you may encounter the following problems, generally because the corresponding package is missing in the system. You can directly install yum without any package.

2. Download and install RabbitMq

[Root @ iZ25e3bt9a6Z rabbitmq] # weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz

Decompress the file

[Root @ iZ25e3bt9a6Z rabbitmq] # xz-d rabbitmq-server-generic-unix-3.6.1.tar.xz
[Root @ iZ25e3bt9a6Z rabbitmq] # tar-xvf rabbitmq-server-generic-unix-3.6.1.tar-C/opt

Decompress the package and enter the folder/opt to find more folder rabbitmq-server-generic-unix-3.6.1, rename it rabbitmq for memory.

Then, add the following environment variable in the configuration of the rabbitmq environment variable vi/etc/profile file:

# Set rabbitmq environment
Export PATH = $ PATH:/opt/rabbitmq/sbin

Source/etc/profile to make the file take effect

3. Close RabbitMQ Service Startup

The above has already completed the installation of RabbitMq. How can I start the service?

Start the service:

[Root @ iZ25e3bt9a6Z rabbitmq] # cd sbin/
[Root @ iZ25e3bt9a6Z sbin] #./rabbitmq-server-detached

View service status:

[Root @ iZ25e3bt9a6Z sbin] #./rabbitmqctl status

Close the service:

[Root @ iZ25e3bt9a6Z sbin] #./rabbitmqctl stop
Stopping and halting node rabbit @ iZ25e3bt9a6Z...

4. Configure the webpage plug-in

Create a directory first; otherwise, an error may be reported:

Mkdir/etc/rabbitmq

Then enable the plug-in:

./Rabbitmq-plugins enable rabbitmq_management

Configure linux port 15672 Web Page Management port 5672 AMQP
Access http: // localhost: 15672.

Default User guest password guest

5. Remote Access Configuration

By default, webpage access is not allowed. You need to add a user to modify the permission. The Code is as follows:

Add User: rabbitmqctl add_user hxb

Add permission: rabbitmqctl set_permissions-p "/" hxb ".*"".*"".*"

Modify user role rabbitmqctl set_user_tags hxb administrator

Then you can remotely access the service and configure user permissions.

　　

6. Common rabbitmq commands

Add_user <UserName> <Password>

Delete_user <UserName>

Change_password <UserName> <NewPassword>

List_users

Add_vhost <VHostPath>
