安装erlang

erlang官网：https://www.erlang.org/

# 添加erlang源
echo "deb https://packages.erlang-solutions.com/ubuntu bionic contrib" | sudo tee /etc/apt/sources.list.d/erlang-solution.list
# 添加密钥，使拥有拉取权限
wget -O- https://packages.erlang-solutions.com/ubuntu/erlang_solutions.asc | sudo apt-key add -
# 查看版本
apt-cache madison erlang
# 安装erlang，-y表示确认
sudo apt-get install erlang=1:25.2.2-2 -y
# 通过查看erlang信息来确认安装结果
erl 或者erl -version

安装RabbitMq

RabbitMQ官网：https://www.rabbitmq.com/

# 添加RabbitMQ源
curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash
# 查看源中版本
apt-cache madison rabbitmq-server
# 安装指定版本的rabbitmq
sudo apt-get install rabbitmq-server=3.11.15-1
# 查看安装结果
service rabbitmq-server status

• RabbitMQ基本命令

  1. 启动：service rabbitmq-server start
  2. 停止：service rabbitmq-server stop
  3. 重启：service rabbitmq-server restart

• 启用 RabbitMQ的web端可视化操作界面

  # 启用可视化插件
  sudo rabbitmq-plugins enable rabbitmq_management   
  # 重启生效
  sudo service rabbitmq-server restart    

注意

在安装过程中，可能出现一下错误

The following packages have unmet dependencies:
 erlang-nox : Depends: erlang-crypto
              Depends: erlang-diameter but it is not going to be installed
              Depends: erlang-edoc
              Depends: erlang-eldap but it is not going to be installed
              Depends: erlang-erl-docgen
              Depends: erlang-inets
              Depends: erlang-odbc

              Depends: erlang-percept
              Depends: erlang-public-key
              Depends: erlang-snmp

 出现该错误的原因是ubuntu源的问题

sudo vi /etc/apt/sources.list

 然后将里面的源替换成官方阿里源，内容如下，保存，退出

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
 
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

执行语句 

sudo apt-get update

再执行之前操作 

完！
