Pre-Installation Task

RabbitMQ has dependencies on the third-party package socat and logrotate. Before you install the RabbitMQ, run the rpm -qa|grep socat and rpm -qa|grep logrotate commands to check whether they have been installed on the server. If they have not been installed yet, you can choose either option below to install the dependencies.

oOnline Install: run the yum -y install socat and yum -y install logrotate commands to install them online.

oOffline Install: refer to Offline Installing Third-party Dependencies for more details.

Note: If the Service Monitor Agent was not previously installed, it will be installed with RabbitMQ. You'll need to use the interactive command line to install it. See Installing MongoDB on Linux for more details. You can also install the Service Monitor Agent separately before installing RabbitMQ.

Installing RabbitMQ on Linux

1.Log in to the Linux server as the root user.

2.Run the mkdir command to create a directory under the /opt directory to place the installation package. For example, netbraintemp10.1.

3.Run the cd /opt/netbraintemp10.1 command to navigate to the /opt/netbraintemp10.1 directory.

4.Download the installation package.

▪Option 1: If the Linux server has no access to the Internet, obtain the rabbitmq-linux-x86_64-rhel-3.8.19-10.1.tar.gz file from NetBrain and then upload it to the /opt/netbraintemp10.1 directory by using a file transfer tool.  

▪Option 2: If the Linux server has access to the Internet, run the
wget <download link> command under the /opt/netbraintemp10.1 directory to directly download the rabbitmq-linux-x86_64-rhel-3.8.19-10.1.tar.gz file from NetBrain official download site.

Note: Contact NetBrain Support Team to get the download link. The download link is case-sensitive.

Tip: Run the yum -y install wget command to install the wget command if it has not been installed on the server.

5.Run the tar -zxvf rabbitmq-linux-x86_64-rhel-3.8.19-10.1.tar.gz command under the /opt/netbraintemp10.1 directory to extract installation files.

[root@localhost netbraintemp10.1]# tar -zxvf rabbitmq-linux-x86_64-rhel-3.8.19-10.1.tar.gz
rabbitmq/
rabbitmq/config/
rabbitmq/config/setup.conf
...
rabbitmq/install.sh
..

6.Run the cd rabbitmq/config command to navigate to the config directory.

7.Modify the parameters in the setup.conf file and save the changes. For how to modify the configuration file, refer to Editing a File with VI Editor.

[root@centos config]# vi setup.conf

# Log path
LogPath=/var/log/rabbitmq

8.Run the cd .. command to navigate to the rabbitmq directory.

9.Run the ./install.sh script under the rabbitmq directory to install RabbitMQ.
