RabbitMQ启动出现的问题与解决办法

　　问题1

　　使用命令启动

　　service rabbitmq-server start

　　报错如下：

　　Starting rabbitmq-server (via systemctl): Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

　　[FAILED]

　　解决办法：

　　尝试下面的操作：

　　禁用 SELinux ，修改 /etc/selinux/config

　　SELINUX=disabled

　　修改后重启系统

　　问题2：

　　一般使用命令

　　rabbitmq-server start

　　可以查看启动相关日志的

　　BOOT FAILED

　　init terminating in do_boot ()

　　Crash dump is being written to: erl_crash.dump...done

　　解决办法：

　　find / -name recovery.dets

　　然后使用 rm 命令删除掉 recoer.dets 文件

　　问题4 ：

　　使用命令

　　rabbitmq-server start

　　报错如下： 提示 no space left on device

　　/usr/lib/rabbitmq/bin/rabbitmq-server: line 51: echo: write error: No space left on device

　　Failed to write pid file: /var/lib/rabbitmq/mnesia/rabbit@n3.pid

　　解决办法：

　　查看磁盘占用情况

　　df -h

　　然后使用

　　cd / #回到根目录

　　du -sh * # 查看各个文件夹占用磁盘情况

　　然后看哪个盘数据多， 就cd 进入哪个盘，然后进行最终找到数据量大的文件。一般是日志文件的话，删除即可。

　　启动异常

　　rabbitmq-server start

　　报错如下：

　　如何解决无锡人流医院哪家好 http://www.ytsg029.com/

　　问题分析，从node1的启动报错来看，像是集群信息残留。在node2上操作将node1移除集群，node1的rabbitmq服务已经down掉了，所以数据库无法同步更新，记载的仍是旧的集群信息(数据库记录里自身节点仍属于集群)，而node2和node3的数据库记录已经更新(数据库信息里面集群不包含node1节点了)。

　　那么就得将这个节点mnesia 数据删掉

　　找到mnseia 目录

　　mv mnesia/ /tmp/

　　如果删了，发现 启动还是报错，很有可能你 删错了 mnesia

　　find / -name mnesia

　　查找下，然后再次删除，然后重启

　　问题，节点加入集群后出现黄框

　　解决办法：

　　rabbitmq-plugins enable rabbitmq_management

　　增加用户 并且赋予角色

　　rabbitmqctl add_user root root

　　rabbitmqctl set_user_tags root administrator

　　问题：

　　如果节点启动

　　rabbitmq-server start

　　报错如下：

　　BOOT FAILED

　　===========

　　Timeout contacting cluster nodes: [rabbit@node2].

　　BACKGROUND

　　==========

　　This cluster node was shut down while other nodes were still running.

　　To avoid losing data, you should start the other nodes first, then

　　start this one. To force this node to start, first invoke

　　"rabbitmqctl force_boot". If you do so, any changes made on other

　　cluster nodes after this one was shut down may be lost.

　　DIAGNOSTICS

　　===========

　　attempted to contact: [rabbit@node2]

　　rabbit@node2:

　　* connected to epmd (port 4369) on node2

　　* node rabbit@node2 up, 'rabbit' application running

　　current node details:

　　- node name: rabbit@node1

　　- home dir: /root

　　- cookie hash: jIUJ2lMKMbDhJLdCJgFDAA==

　　{"init terminating in do_boot",timeout_waiting_for_tables}

　　解决办法：

　　rabbitmqctl force_boot

　　问题：

　　rabbitmq-server: unrecognized service

　　解决办法

　　hostname

　　查看hostname是否正确

　　如果使用

　　vi /etc/hosts

　　修改了host但是不生效， 那么查看

　　/etc/sysconfig/network

　　这个目录下的hostname 是否写死了， 把它修改了，然后重启 reboot

　　nohup启动

　　nohup ./rabbitmq-server start &
