Rabbitmq 安装启动中遇到的坑

在做消息投递和消费的并发测试的时候，Rabbitmq 崩了，管理页面无法访问，消息无法投递，也不能消息。

想到的解决方法是重启，但输入命令：servicre rabbitmq-server stop

1
ERROR: node with name "rabbit" already running on "localhost"

无论restart、stop、start都报这个错。原因是RabbitMQ已在localhost里运行了，但是停止不了。解决记录如下：

但是上述的启动方式会因为退出而关闭。

采用如下方式可以解决

[root]# /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.15/sbin/rabbitmq-server -detached
Warning: PID file not written; -detached was passed.

但是输入命令,提示没有权限

Note: This output shows SysV services only and does not include native

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

想要加入系统自启动，却怎么也不行。

[  sbin]# systemctl enable rabbitmq-server.service
rabbitmq-server.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig rabbitmq-server on

打开 cat /usr/sbin/chkconfig 又是乱码

还有提出建立一个软连接的，也不行。

/usr/lib/rabbitmq/bin/rabbitmq-server
/usr/lib/ocf/resource.d/rabbitmq/rabbitmq-server
/usr/sbin/rabbitmq-server

没有明白怎么会有这么多安装路径。

想要通过命令添加用户，发现网上教程也都是按照rabbitmqctl 的方式添加。由于没有添加systemctl成功，不再折腾。

最后按照-detached 启动的方式启动，不在折腾。
