[root@ngiam-01 ~]# systemctl stop mongod.service Warning: mongod.service changed on disk. Run 'systemctl daemon-reload' to reload units.

这个警告是因为mongod.service的文件被修改了，但systemd没有重新加载它。您可以通过运行以下命令来重新加载systemd配置文件并重启mongod服务：

sudo systemctl daemon-reload
sudo systemctl restart mongod

这将重新加载mongod.service文件，并重新启动mongod服务。

这个错误提示是 MongoDB 数据库服务启动失败了。可能是由于一些配置问题，或者是由于其他进程占用了 MongoDB 的端口。你可以尝试查看 MongoDB 的日志文件，看是否有更具体的错误信息，或者查看系统日志文件，看是否有其他进程占用了 MongoDB 的端口。同时，你也可以检查 MongoDB 的配置文件，确保配置正确。

这是一个 Ansible 的错误信息，看起来是在执行 jingantech.nexus.nexus 这个角色时出现的问题。具体错误是：无法找到或访问 '../accessory/nexus-3.37.3-02-unix-centos7.tar.gz' 文件。这个错误提示了在多个路径下搜索了这个文件但都没有找到，如果你在使用一个模块并期望文件存在于远程主机上，可以考虑使用 remote_src 选项。
