查看rabbitmq版本

要查看RabbitMQ的版本，请执行以下步骤：

1.打开RabbitMQ的管理界面
2.在页面的底部，您将找到“RabbitMQ Management”的版本号，它显示在“Powered by”下面。
3.您还可以在命令行中运行以下命令来获取RabbitMQ版本：

rabbitmqctl status

这将显示RabbitMQ节点的各种信息，包括版本号。

linux查看rabbitmq版本

### 回答1：
可以使用以下命令来查看RabbitMQ的版本：

rabbitmqctl status | grep RabbitMQ

其中，rabbitmqctl是RabbitMQ的控制命令，status表示查看RabbitMQ的状态，grep RabbitMQ是用来过滤出包含RabbitMQ关键字的信息。执行该命令后，会输出类似以下的信息：

Status of node 'rabbit@localhost' ...
[{pid,1234},
{running_applications,[{rabbit,"RabbitMQ","3.8.9"},
{rabbit_common,[],"3.8.9"},
{rabbitmq_management,"RabbitMQ Management","3.8.9"},
{rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.8.9"},
{webmachine,"webmachine","1.10.3"},
{mochiweb,"MochiMedia Web Server","2.20.1"}]},
{os,{unix,linux}},
{erlang_version,"22.3.4.16"},
{memory,[{total,123456789},
{connection_readers,},
{connection_writers,},
{connection_channels,},
{connection_other,},
{queue_procs,},
{queue_slave_procs,},
{plugins,},
{other_proc,123456789},
{mnesia,},
{mgmt_db,},
{msg_index,},
{other_ets,}]},
{alarms,[]},
{listeners,[{clustering,25672,"::"},{amqp,5672,"::"}]},
{vm_memory_high_watermark,.4},
{vm_memory_limit,1073741824},
{disk_free_limit,50000000},
{disk_free,123456789},
{file_descriptors,[{total_limit,924},
{total_used,4},
{sockets_limit,829},
{sockets_used,2}]},
{processes,[{limit,1048576},{used,123}]},
{run_queue,},
{uptime,123456789},
{kernel,{net_ticktime,60}}]

其中，RabbitMQ的版本号为3.8.9。

### 回答2：
RabbitMQ是一种开源的消息中间件，它支持多个协议，包括AMQP（高级消息队列协议）和STOMP（可简单传输消息协议），可以用于构建分布式应用程序。在Linux系统上，使用以下命令可以查看RabbitMQ版本：

1. 使用rabbitmqctl命令

先使用sudo命令切换到root用户，然后输入以下命令：

rabbitmqctl status

该命令将返回RabbitMQ服务器的状态信息，其中包括RabbitMQ服务器的本地版本信息。有时候，rabbitmqctl这个命令可能由于环境变量问题而无法找到。这种情况下，可以在命令前面加上sudo，以root用户的身份运行。

2. 使用rabbitmq-server命令

另一种查看RabbitMQ版本的方法是使用rabbitmq-server这个命令：

sudo rabbitmq-server -version

该命令将返回RabbitMQ服务器的版本信息。

无论是使用rabbitmqctl还是rabbitmq-server命令，都可以方便地查看RabbitMQ版本信息。在开发和测试过程中，需要不断了解所采用的技术栈中各种软件和工具的版本信息，以便进行问题排查和性能优化。

### 回答3：
在Linux系统中，我们可以通过多种方式来查看已安装的 RabbitMQ 版本。

1. 使用 rabbitmqctl 命令

rabbitmqctl 是 RabbitMQ 自带的命令行工具，我们可以通过执行以下命令来查看版本信息：

sudo rabbitmqctl status

执行完命令后，会输出 RabbitMQ 的版本信息，如下所示：

Status of node rabbit@localhost ...
[{pid,xxxx}, {running_applications,
                  [{rabbitmq_management,"RabbitMQ Management Console","3.9.7"},
                   {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.9.7"},
                   {rabbitmq_management_agent,"RabbitMQ Management Agent","3.9.7"},
                   {rabbitmq_auth_backend_ldap,"LDAP Authentication Backend","3.9.7"},
                   {rabbitmq_auth_mechanism_ssl,"SSL Authentication Mechanism","3.9.7"},
                   {rabbitmq_shovel_management,"Shovel Management Plugin","3.9.7"},
                   {rabbitmq_auth_backend_cache,"Caching Authentication Backend","3.9.7"},
                   {rabbitmq_mqtt,"RabbitMQ MQTT Adapter","3.9.7"},
                   {rabbitmq_recent_history_exchange,"RabbitMQ Recent History Exchange","3.9.7"},
                   {rabbitmq_consistent_hash_exchange,"RabbitMQ Consistent Hash Exchange","3.9.7"},
                   {rabbitmq_federation_management,"Federation Management Plugin","3.9.7"},
                   {rabbitmq_event_exchange,"RabbitMQ Event Exchange","3.9.7"},
                   {rabbitmq_federation,"RabbitMQ Federation","3.9.7"},
                   {rabbitmq_random_exchange,"RabbitMQ Random Exchange","3.9.7"},
                   {rabbitmq_amqp1_0,"AMQP 1.0 support plugin","3.9.7"},
                   {rabbitmq_management_visualiser,"RabbitMQ Management Visualiser","3.9.7"},
                   {rabbit,"RabbitMQ","3.9.7"},
                   {rabbit_common,[],"3.9.7"},
                   {amqp_client,"RabbitMQ AMQP Client","5.6.0"},
                   {rabbitmq_prometheus,"RabbitMQ Prometheus Adapter","3.9.7"}]},
 {os,{unix,linux}},
 {erlang_version,"24.0.5"},
 {memory,[{connection_readers,0},
          {connection_writers,0},
          {connection_channels,0},
          {connection_other,13776},
          {queue_procs,27512},
          {queue_slave_procs,0},
          {plugins,0},
          {other_proc,106791992},
          {mnesia,117776},
          {mgmt_db,0},
          {msg_index,0},
          {other_ets,3172904},
          {binary,68324},
          {code,27758417},
          {atom,235669},
          {other_system,12130443}]},
 {disk_free_limit,50000000},
 {disk_free,192183007232},
 {file_descriptors,[{total_limit,1048576},
                    {total_used,604},
                    {sockets_limit,943626},
                    {sockets_used,588}]},
 {processes,[{limit,1048576},{used,296}]},
 {run_queue,0},
 {uptime,576},
 {kernel,{net_ticktime,60}}]

在上述输出结果中，我们可以看到 RabbitMQ 的版本号是 “{rabbit,"RabbitMQ","3.9.7"}” .

2. 查看 RabbitMQ 安装目录下的版本文件

在 Linux 中，RabbitMQ 的版本文件位于 /usr/lib/rabbitmq/erlang/lib/rabbitmq_server-x.x.x/ebin/ 目录下，我们可以通过 cd 命令切换到该目录下，执行 ls 命令查看可以看到版本文件名类似 rabbit_common-3.9.7.ez，其中 3.9.7 即为 RabbitMQ 当前的版本。

3. 查看 erlang 包依赖版本

RabbitMQ 是基于 Erlang 编写的，我们可以通过执行以下命令来查看 erlang 依赖的 RabbitMQ 版本：

sudo erl -eval '{ok, A} = file:read_file(filename:join([code:root_dir(), "lib", "rabbitmq_server-3.9.7", "ebin", "rabbit.app"])), {ok, [{version, V}]} = re:run(A, ".*{version, \"(\\d+\\.\\d+\\.\\d+)\"}.*", [{capture, [1]}]), io:format("~s~n", [V]), halt().' -noshell

执行完命令后，会输出 RabbitMQ 的版本信息，如下所示：

"3.9.7"

以上是 Linux 查看 RabbitMQ 版本的三种方式。

服务器 docker 如何查看rabbitmq 版本号

要查看运行在 Docker 中的 RabbitMQ 版本号，可以使用以下命令：

docker exec <rabbitmq-container-name> rabbitmqctl status | grep RabbitMQ

其中，`<rabbitmq-container-name>` 是 RabbitMQ 容器的名称。

执行上述命令后，会输出 RabbitMQ 的相关信息，其中包括版本号，例如：

Status of node rabbit@<container-id> ...
[{pid,<pid>},
 {running_applications,[{rabbitmq_management,"RabbitMQ Management Console","3.6.9"},
                        {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.6.9"},
                        {rabbitmq_management_agent,"RabbitMQ Management Agent","3.6.9"},
                        {rabbit,"RabbitMQ","3.6.9"},
                        {mnesia,"MNESIA  CXC 138 12","4.14.3"},
                        {amqp_client,"RabbitMQ AMQP Client","3.6.9"},
                        {rabbit_common,[],"3.6.9"},
                        {os_mon,"CPO  CXC 138 46","2.4"},
                        {cowboy,"Small, fast, modern HTTP server.","1.0.1"},
                        {cowlib,"Support library for manipulating Web protocols.","1.0.0"},
                        {jsx,"a streaming, evented json parsing toolkit","2.8.2"}]},
 {os,{unix,linux}},
 {erlang_version,"Erlang/OTP 19 [erts-8.3.5.6] [source] [64-bit] [smp:4:4] [async-threads:64] [kernel-poll:true]\n"},
 {memory,[{total,58824560},
          {connection_readers,0},
          {connection_writers,0},
          {connection_channels,0},
          {connection_other,0},
          {queue_procs,0},
          {queue_slave_procs,0},
          {plugins,0},
          {other_proc,192168},
          {mnesia,11496},
          {mgmt_db,0},
          {msg_index,0},
          {other_ets,1524800},
          {binary,16680},
          {code,23251859},
          {atom,1338425},
          {other_system,1985011}]},
 {alarms,[]},
 {listeners,[{clustering,25672,"::"},{amqp,5672,"::"}]},
 {vm_memory_high_watermark,0.4},
 {vm_memory_limit,834841753},
 {disk_free_limit,50000000},
 {disk_free,8942155264},
 {file_descriptors,[{total_limit,1048576},
                    {total_used,2},
                    {sockets_limit,943626},
                    {sockets_used,0}]},
 {processes,[{limit,1048576},{used,192169}]},
 {run_queue,0},
 {uptime,4258}]

在上述信息中，可以看到 RabbitMQ 的版本号为 `3.6.9`。
