1. Log in to the cloud server
2. Download and install erlang
wget http://erlang.org/download/otp_src_19.3.tar.gz
Unzip after downloading: tar -xvzf otp_src_19.3.tar.gz
Erlang needs to install its dependencies before installation:
yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC-devel
Then enter the decompressed file to configure the installation environment for erlang
./configure --prefix=/usr/erlang --without-javac
then compile make
then install make install
Then you can verify that erlang is installed successfully
Then exit, tried a few commands to no avail, and finally control+C to exit
Next, you need to configure the environment variables, configure Erlang to the /etc/profile file and set it to take effect through source /etc/profile
Then configure the Erlang environment variables, vi /etc/profile file, and add the following environment variables:
#set erlang environment
export PATH=$PATH:/opt/erlang/bin
source /etc/profile makes the file take effect
3. Install RabbitMQ
Download via command line: wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.8/rabbitmq-server-3.6.8-1.el7.noarch.rpm
After the download is complete, follow the documentation and execute it first:
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
Then execute:
yum install rabbitmq-server-3.6.8-1.el7.noarch.rpm
Check if the installation is complete:
rpm -i --nodeps rabbitmq-server-3.6.8-1.el7.noarch.rpm
4. RabbitMQ service startup and shutdown
The above has completed the installation of RabbitMq, how to start the service?
rabbitmq-server start
Adding rabbitmq to the startup item can be done with the command: chkconfig rabbitmq-server on
There is also a command to open the management interface: rabbitmq-plugins enable rabbitmq_management
