RabbitMQ

NetWorker 服务器将 RabbitMQ 用作消息 Broker 代理服务;它在 NetWorker 服务器进程 (nsrd) 与 NetWorker 使用的其他服务(例如 authc、NetWorker Management Console [NMC]、NetWorker Web User Interface [NWUI] 等)之间提供消息排队机制。RabbitMQ 服务问题导致 NetWorker 服务器服务关闭;一般消息记录在 NetWorker 服务器的 daemon.raw 中:

  • Linux: /nsr/logs/daemon.raw
  • Windows: ..\Program Files\EMC NetWorker\nsr\logs\daemon.raw

日志文件:

日志路径因使用的 rabbitmq-server 版本而异。NetWorker 版本可能包括较新版本的 RabbitMQ。特定于版本的详细信息可在《NetWorker 安装指南》和《NetWorker 管理指南》中找到,网址为: https://www.dell.com/support/home/en-us/product-support/product/networker/docs

Linux 日志位置:
/nsr/logs/daemon.raw NetWorker 服务日志
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/log/crash.log RabbitMQ 崩溃日志,此目录包含 crash.log#,具体取决于日志轮换。
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/rabbit@localhost.log RabbitMQ 常规日志
/opt/nsr/rabbitmq-server*/var/log/rabbitmq/rabbit@localhost_upgrade.log RabbitMQ 升级日志
/nsr/tmp/rabbitmq/cores/erl_crash.dump 崩溃堆栈跟踪日志

 

Windows 日志位置(默认安装位置)
C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw NetWorker 服务日志
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\log\crash.log RabbitMQ 崩溃日志,此目录包含 crash.log#,具体取决于日志轮换。
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\rabbit@HOSTNAME.log RabbitMQ 常规日志
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\log\rabbit@HOSTNAME_upgrade.log RabbitMQ 升级日志
C:\Program Files\EMC NetWorker\nsr\tmp\RabbitMQ\cores\erl_crash.dump 崩溃堆栈跟踪日志

 

调试:

调试选项可能因 RabbitMQ 版本而异。版本由下面的 rabbitmq-server 文件夹指示:

  1. NetWorker 19.6-19.9:3.8.18
  2. NetWorker 19.10:3.11.16
  1. Linux: /opt/nsr/rabbitmq-server-#.#.#
  2. Windows..\Program Files\EMC NetWorker\nsr\rabbitmq-server-#.#.#
    1. 复制原始的 rabbitmq.config。
      Linux: /opt/nsr/rabbitmq-server-3.8.18/etc/rabbitmq/rabbitmq.config
      Windows: ..\Program Files\EMC NetWorker\nsr\rabbitmq-server-3.8.18\etc\rabbitmq.config
    2. 编辑 rabbitmq.config 文件以包含以下行:
      Linux:
      %% {log_levels, [{channel, info}, {connection, info}, {federation, info}, {mirroring, info}]},
            {log_levels, [{connection, debug}, {queue, debug}]},
                 {log,
                      [{file, [{level, debug}]},
                      {categories,
                          [{connection,
                              [{level, debug}]
                          },
                          {queue,
                              [{level, debug}]
                          }
                          ]
                      }]
                  },
      提醒:注释行 (%%) 已经存在,更改可以添加到此行下。
      Windows:
      在文件顶部添加以下突出显示的行。
      [  
       {rabbit, 
       [{tcp_listeners, []}, 
       {log_levels, [{connection, debug}, {queue, debug}]},
                 {log,
                      [{file, [{level, debug}]},
                      {categories,
                          [{connection,
                             [{level, debug}]
                          },
                          {queue,
                              [{level, debug}]
                          }
                          ]
                      }]
                  },            
          {ssl_listeners, [5671]}, 
    3. 尝试启动 NetWorker 服务:
      Linux: systemctl restart networker
      Windows: net stop nsrd /y && net start nsrd
    4. 监视 rabbit@localhost.log(如果是 Linux)、rabbit@NODE.log(如果是 Windows),以及 crash.log,以了解是否有可能阻止 RabbitMQ 启动的错误。

 

警告:此调试的目的是进行主动故障处理。例如,当 RabbitMQ 无法启动时。它不应在活动的 NetWorker 服务器上处于启用和无人值守状态。如果 RabbitMQ 正常运行,此调试可能会使用数千个与 Java 的端口连接,从而停止响应 NetWorker 服务器及其用户界面。完成故障处理后,通过将 rabbitmq.config 文件恢复到其默认设置来删除调试,或者恢复为在添加调试行之前创建的 rabbitmq.config 文件的副本。禁用调试后,RabbitMQ 需要重新启动 NetWorker 服务才能重新加载配置文件。

 

当 RabbitMQ 运行时,NetWorker 服务器应侦听端口 5671 (SSL)。

nsrports -t localhost -p 5671

您可以使用以下命令获取侦听 5671 的进程的进程 ID (PID)。与端口 5671 关联的进程应来自 rabbitmq-server。

Linux:

netstat -apno | grep 5671
ps -ef | grep PID

示例:

nve:~ # netstat -apno | grep 5671
