[root@zhangsan Desktop]# rabbitmq-plugins enable rabbitmq_management
{:query, :rabbit@zhangsan, {:badrpc, :timeout}}
原因：Linux主机名不是默认的localhost  所以导致无法启动插件
 
原因：hostname没有追加到/etc/hosts文件中，所以通过默认localhost  hostname访问服务发生timeout。
 建议将追加到/etc/hosts
 
解决方案：
 
方案一：(推荐)
 
参考：https://blog.csdn.net/G971005287W/article/details/109811697
 
linux 主机名需要改为默认的 localhost
 
使用命令 vim /etc/hostname 修改hostname文件
 
例如将 zhangsan.localdomain 修改为 localhost.localdomain 
 
保存 然后重启
 
reboot
 
方案二：(没尝试过)
 
修改hosts
 
127.0.0.1   localhost zhangsan.localdomain localhost4 localhost4.localdomain4
 
在mq目录下  etc/rabbitmq目录下创建文件enabled_plugins，内容如下：
 
[rabbitmq_management].
然后用如下命令启动rabbitmq_management插件
 
umask 0022; rabbitmq-plugins enable rabbitmq_management
 
三、问题Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'CRM-weixin-msg' in vhost '/': received 'false' but current is 'true', class-id=50, method-id=10)
 
正常访问该地址：https://xxx.xxx.com/mq/ 时能正常跳转，
 但是 rabbitmq management 的 API url 出现了 %2f 字符，这些字符会在经过 nginx 被转换为/
 
解决方案：
 
修改 nginx 配置文件
 
    location ^~ /mq/ {
			proxy_pass              http://127.0.0.1:15672/; 
			proxy_set_header        Host $host;
			proxy_set_header        X-Real-IP $remote_addr;
			proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header        Upgrade $http_upgrade;
			proxy_set_header        Connection "upgrade";
			if ($request_uri ~* "/mq/(.*)"){
    			proxy_pass http://127.0.0.1:15672/$1;
    			break;
五、添加用户
 
六、添加权限
 
publisher-confirms: true
 
#如果对异步消息需要回调必须设置为true 因为新版本的写法是这个：
 
publisher-confirm-type: correlated
 
八、启动报错

                                    maven中的仓库分为两种，snapshot快照仓库和release发布仓库。snapshot快照仓库用于保存开发过程中的不稳定版本，release正式仓库则是用来保存稳定的发行版本。定义一个组件/模块为快照版本，只需要在pom文件中在该模块的版本号后加上-SNAPSHOT即可(注意这里必须是大写)，如下：
