Ready to work

• Erlang download the installation package: If the line is too slow to install, can be selected directly from the official website https://www.erlang.org/downloads download

wget http://erlang.org/download/otp_src_22.0-rc2.tar.gz

• Download rabbitmq-server installation package 

wget wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-3.8.2-1.el7.noarch.rpm

Installation Erlang

• Installation depends libraries:
  • yum -y install gcc-c++
  • yum -y install ncurses-devel
  • yum -y install openssl-devel
  • yum -y install unixODBC-devel
• Create a directory (the installation directory specified): mkdir / usr / local / erlang
• Open Directory cd otp_src_22.2 /
• Mounted to the specified directory: ./configure --prefix = / usr / local / erlang --without-Javac
• make && make install
• After installation is complete configuration & compilation Erlang environment variables: vim / etc / profile
  • Appended to the end of the file environment variables: export PATH = $ PATH: / usr / local / erlang / bin

  • source /etc/profile

RabbitMQ installation

• Loading Source: rpm -ivh --nodeps rabbitmq-server-3.8.2-1.el7.noarch.rpm
• If linux firewall is turned on, the need to do the following
  • firewall-cmd --zone=public --add-port=15672/tcp --permanent
  • firewall-cmd --zone=public --add-port=5672/tcp --permanent
  • firewall-cmd --reload
• start up:
  • rabbitmq-plugins enable rabbitmq_management
  • rabbitmq-server
• Background start: rabbitmq-server -detached
• Create a login account, password: rabbitmqctl add_user [account] [password]
• Grant administrator privileges: rabbitmqctl set_user_tags [account] administrator
• Authorized user to the virtual machine (/): '. *' Rabbitmqctl set_permissions -p / [Account] '*'. '*.'
• Configure boot from the start:
• Adding custom startup script:
• Create a rabbitmq-server file in the /etc/init.d directory, as follows:

• • Set execute permissions, the command: chmod a + x /etc/init.d/rabbitmq-server

Add boot entry:
• Add command: chkconfig --add /etc/init.d/rabbitmq-server
• View startup items, command: chkconfig --list
• We need to set rabbitmq-server start command: chkconfig rabbitmq-server on
• Close command: chkconfig rabbitmq-server off
• Delete command: chkconfig --del rabbitmq-server
• Run reboot, reboot the server to verify nginx boot
