MongoDB数据库启动失败
目录
问题
自己的云转码服务器用到了MongoDB数据库,使用docker部署的有些情况下,转码服务启动时会遇到数据库服务无法伴随启动的现象。
这个时候,就必须依赖自己手动启动数据库服务。
相关的报错信息如下:
0|www | (node:248) [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.

类似的报错:
Failed to get D-Bus connection: Operation not permitted
解决
手动启动MongoDB数据库服务,需要找到该服务的可执行程序和相应的配置文件,然后使用-f参数执行如下命令:
/usr/bin/mongod -f /etc/mongod.conf
出现successfully信息,表示启动成功。
比如:
[root@731ae35768eb boffmpeg]# /usr/bin/mongod -f /etc/mongod.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3304
child process started successfully, parent exiting
但是,最直接的方式还是在运行容器的时候,指定特殊权限,具体命令可以参考:
docker run -itd --net=host --restart=always --name boffmpeg --privileged=true 0ba8f07ac61d /usr/sbin/init
