This article mainly explains "how to build rabbitMQ single node in linux environment". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to build rabbitMQ single node in linux environment".

Linux environment CentOS-6.5-x86_64

Erlang version of otp_src_20.0.tar.gz

Wget http://erlang.org/download/otp_src_20.0.tar.gz

RabbitMQ version of rabbitmq-server-generic-unix-3.6.15.tar.xz

Https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/

Start building.

Modify hosts first to name the host name. 192.168.220.129 is an IP of my virtual machine.

# vi / etc/hosts

192.168.220.129 rabbitmq

# cd / usr/local/src (upload otp_src_20.0.tar.gz and rabbitmq-server-generic-unix-3.6.15.tar to this directory)

# tar xvf otp_src_20.0.tar.gz (since rabbitmq is developed in the erlang language, install the erlang environment first)

# cd otp_src_20.0

#. / configure-prefix=/usr/local/erlang-with-ssl-enable-threads-enable-smp-support-enable-kernel-poll-enable-hipe-without-javac

After execution, ncurses-devel.x86_64 is also required if the red box shown in the following figure appears

Will report a small mistake: Makefile:248: / usr/local/otp_src_20.0/make/x86_64-unknown-linux-gnu/otp_ded.mk: No such file or directory error: No curses library functions found

# yum install ncurses-devel.x86_64

#. / configure-prefix=/usr/local/erlang-with-ssl-enable-threads-enable-smp-support-enable-kernel-poll-enable-hipe-without-javac

Continue to execute, and the following message appears, indicating that it is normal

# make & & make install

After installation, configure the environment variables for erlang

# vi / etc/profile

Save exit after adding

# source / etc/profile

Use source to make the file effective immediately

# erl

The erlang environment is OK, followed by the installation of rabbitMQ

# cd / usr/local/src

# tar xvf rabbitmq-server-generic-unix-3.6.15.tar

[root@rabbitmq src] # mv rabbitmq_server-3.6.15/.. / rabbitmq

# vi / etc/profile

Configure the rabbitMQ environment variable as shown above and execute source / etc/profile

# source / etc/profile

# rabbitmq-server-detached

Execute rabbitmq-server-detached to start the background daemon, otherwise rabbitmq exits after shell exits.

# rabbitmqctl status

Check whether the rabitmq status is started, if the following error is thrown

Status of node rabbit@rabbitmq

Error: unable to connect to node rabbit@rabbitmq: nodedown

DIAGNOSTICS

=

Attempted to contact: [rabbit@rabbitmq]

Rabbit@rabbitmq:

* connected to epmd (port 4369) on rabbitmq

* epmd reports: node 'rabbit' not running at all

No other nodes on rabbitmq

* suggestion: start the node

Current node details:

-node name: 'rabbitmq-cli-31@rabbitmq'

-home dir: / root

-cookie hash: JTCyebhk7sHDdUd5ICe4kg==

Execute rabbitmq-service stop to stop the service first.

# rabbitmq-server stop

If the following command is thrown after the stop command is executed, it probably means that erlang also depends on openssl

BOOT FAILED

=

Error description:

{error, {missing_dependencies, [crypto,ssl]

[cowboy,cowlib,rabbitmq_management

Rabbitmq_management_agent

Rabbitmq_trust_store]}}

Go to the / usr/local/src directory to download openssl

# cd / usr/local/src

# wget http://www.openssl.org/source/openssl-1.0.1s.tar.gz

# tar-zvxf openssl-1.0.1s.tar.gz

# cd openssl-1.0.1s

#. / config-prefix=/usr/local/openssl

# vi Makefile

Use / search CFLAG to add as shown in the following figure, which is actually adding-fPIC

# make & & make install

After the installation is complete, you also need to reinstall erlang. There is a change in the way that openssl specifies the installation path and goes back to the otp_src_20.0 installation package.

# cd / usr/local/src/otp_src_20.0

#. / configure-prefix=/usr/local/erlang-with-ssl=/usr/local/openssl-enable-threads-enable-smp-support-enable-kernel-poll-enable-hipe-without-javac

# make & & make install

After the installation is complete, restart rabbitmq

# rabbitmq-server-detached

# ps-ef | grep rabbitmq

# rabbitmqctl status

The rabbitmq service has been built, and then the rabbitmq web service is opened. When you see started 6 plugins, it indicates that the service has been started successfully.

# rabbitmq-plugins enable rabbitmq_management

The rest is to turn on the firewall.

# vi / etc/sysconfig/iptables

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 5672-j ACCEPT

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 15672-j ACCEPT

# service iptables restart

Open the browser and enter your IP:15672 to access it.
