泛微E10(e-cology)运维管理平台安装周边服务rabbitmq启动失败
泛微E10(e-cology)运维管理平台安装周边服务消息队列rabbitmq启动失败解决办法服务器：Ubuntu 22.04.3 LTS
泛微ECOLOGY运维管理平台： e-monitor-V5.0.6.020230917-RC
因为泛微E10运维管理平台对ubuntu 22.04版本兼容不好，安装之前，编辑rabbitmq自动化运维(ansible)安装包：/opt/e-monitor/ecology/tools/ansible-rabbitmq-3.7.7.zip修改后，安装的对应版本为：
Erlang版本：Erlang 24.2.1
RabbitMQ版本：RabbitMQ 3.8.16
安装周边服务时，提示消息队列rabbitmq安装失败，如图：
原因及解决方法：
查看/opt/e-monitor/package/ansible-rabbitmq/ansible-rabbitmq 自动化运维记录文件，发现执行到启动rabbitmq-server服务时，提示任务失败，相关执行记录如下：
TASK *********
fatal: : FAILED! => {"changed": false, "msg": "Unable to restart service rabbitmq-server: Job for rabbitmq-server.service failed because the control process exited with error code.\nSee \"systemctl status rabbitmq-server.service\" and \"journalctl -xeu rabbitmq-server.service\" for details.\n"}
NO MORE HOSTS LEFT *************************************************************
PLAY RECAP *********************************************************************
mqeef76 : ok=27 changed=7 unreachable=0 failed=1 skipped=12 rescued=0 ignored=1
根据运行记录，发现是在启动 rabbitmq 服务时出现在错误，于是我们在手工运行一次启动命令：service rabbitmq-server start
systemctl start rabbitmq-server
发现果然启动错误，我们根据提示，执行了 journalctl -xe ，定位到详细的报错日志信息；
journalctl -xe
通过这个执行到命令行后，会打印出非常多的问题信息，让我们继续往下定位到ERROR处：

Feb 13 15:37:51 mqeef76 rabbitmq-server: 15:37:51.698
查看打印出来的前四条错误信息为： Error parsing configuration:
File operation error: eacces. Target: /etc/rabbitmq/rabbitmq.conf. Function: get_file. Process: rabbit_prelaunch_sup.
- Could not open file (/etc/rabbitmq/rabbitmq.conf) for Reason undefined
Are these files using the Cuttlefish format?
接下来，我们来检查RabbitMQ配置文件中是否存在任何错误。你可以使用以下命令检查配置文件的语法是否正确：rabbitmqctl eval 'file:consult([{config_file}, {silent, true}]).'或者查看 rabbitmq 状态
rabbitmqctl status运行这两条命令显示结果相同，显示内容如下：
Error: unable to perform an operation on node 'rabbit@mqeef76'. Please see diagnostics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
* CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
* Target node is not running
In addition to the diagnostics info below:
* See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@mqeef76
* If target node is configured to use long node names, don't forget to use --longnames with CLI tools
DIAGNOSTICS
===========
attempted to contact:
rabbit@mqeef76:
* connected to epmd (port 4369) on mqeef76
* epmd reports: node 'rabbit' not running at all
no other nodes on mqeef76
* suggestion: start the node
Current node details:
* node name: 'rabbitmqcli-24-rabbit@mqeef76'
* effective user's home directory: /opt/weaver/rabbitmq
* Erlang cookie hash: uwA6pPy2Z6X3QNPinvgy9w==
通过以上错误信息，检查 /etc/rabbitmq/rabbitmq.conf 配置文件有没有错误，发现abbitmq.conf文件权限为640，把权限改为644，再次运行“service rabbitmq-server start”命令启动服务，发现已启动正常。
重新安装rabbitmq办法：
删除上次安装目录和信息残留，即删除rabbitmq目录和已有 mnesia 信息
rm -rf /opt/weaver/rabbitmq
rm -rf /var/lib/rabbitmq
注：
安装日志文件：/opt/e-monitor/package//logs/install.log
rabbitmq账号密码文件：
/opt/e-monitor/package/ansible-rabbitmq/rabbitmq.yml
/opt/e-monitor/package/config/db.properties
相关命令：
# 查看erlang版本
erl -version
Erlang (SMP,ASYNC_THREADS) (BEAM) emulator version 12.2.1
# 查看RabbitMQ版本号：
进入在escript目录下可以获取到版本号
# cd /usr/lib/rabbitmq/lib/rabbitmq_server-3.8.16/escript/
# rabbitmqctl version
3.8.16
# 检查RabbitMQ运行状态
rabbitmqctl status
# 查找RabbitMQ的安装路径
whereis rabbitmq
rabbitmq: /usr/lib/rabbitmq /etc/rabbitmq
# 启动 rabbitmq 服务
service rabbitmq-server start
systemctl start rabbitmq-server
# 关闭 rabbitmq 服务
service rabbitmq-server stop
# 重启 rabbitmq 服务
service rabbitmq-server restart
# 查看 rabbitmq 状态
service rabbitmq-server status
# 查看 rabbitmq 进程
我们可以通过ps -ef|grep rabbitmq命令来看 rabbitmq服务是否是启动
ps -ef | grep rabbitmq
