linux 安装rabbitmq

好的，以下是在 Linux 系统下安装 RabbitMQ 的步骤：

1. 安装 Erlang：RabbitMQ 是使用 Erlang 语言开发的，因此需要先安装 Erlang。可以通过以下命令在 Ubuntu 系统上安装 Erlang：

   sudo apt-get update
   sudo apt-get install erlang

2. 添加 RabbitMQ 的 APT 源：RabbitMQ 官方提供了 APT 源，可以通过以下命令添加：

   curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash

3. 安装 RabbitMQ：使用以下命令安装 RabbitMQ：

   sudo apt-get update
   sudo apt-get install rabbitmq-server

4. 启动 RabbitMQ：使用以下命令启动 RabbitMQ：

   sudo service rabbitmq-server start

5. 验证 RabbitMQ 是否运行：使用以下命令验证 RabbitMQ 是否已经运行：

   sudo rabbitmqctl status

如果输出类似于以下内容，则说明 RabbitMQ 已经成功安装并启动：

Status of node rabbit@localhost ...
[{pid,1593},
 {running_applications,
     [{rabbitmq_management,"RabbitMQ Management Console","3.7.8"},
      {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.7.8"},
      {rabbitmq_management_agent,"RabbitMQ Management Agent","3.7.8"},
      {rabbit,"RabbitMQ","3.7.8"},
      {rabbit_common,[],"3.7.8"},
      {cowlib,"Cowboy 2.2.0 adapter for Erlang/OTP","2.7.0"},
      {ranch,"Socket acceptor pool for TCP protocols.","1.7.1"},
      {cowboy,"Small, fast, modern HTTP server.","2.7.0"}]},
 {os,{unix,linux}},
 {erlang_version,"21.1.4"},
 {memory,[{total,36291120},
          {connection_readers,0},
          {connection_writers,0},
          {connection_channels,0},
          {connection_other,0},
          {queue_procs,0},
          {queue_slave_procs,0},
          {plugins,0},
          {other_proc,10419336},
          {mnesia,0},
          {mgmt_db,0},
          {msg_index,0},
          {other_ets,0},
          {binary,85736},
          {code,27291943},
          {atom,922993},
          {other_system,1985722}]},
 {alarms,[]},
 {listeners,[{clustering,25672,"::"},{amqp,5672,"::"}]},
 {vm_memory_high_watermark,0.4},
 {vm_memory_limit,1337729233},
 {disk_free_limit,50000000},
 {disk_free,16445234176},
 {file_descriptors,[{total_limit,1048576},
                    {total_used,2},
                    {sockets_limit,943626},
                    {sockets_used,0}]},
 {processes,[{limit,1048576},{used,288}]},
 {run_queue,0},
 {uptime,1504}]

至此，RabbitMQ 已经在 Linux 系统上安装成功。
