MongoDB 3.4 Server not starting with bind error following a CentOS 7.4 security update

centoscentos-7mongodbmongodb-3.4

MongoDB 3.4 server is failing to start following a CentOS security update and reboot.

No configuration changes made. The previous update and reboot a couple of days earlier did not cause any problems. Could the CentOS update be the reason for the problem?

Many thanks, any thoughts are much appreciated!

Error messages in mongod.log

E NETWORK  [initandlisten] listen(): bind() failed Cannot assign requested address for socket: xxx.xxx.xxx.xxx:27017
E NETWORK  [initandlisten] Failed to set up sockets during startup.

@smile2day, It's pretty clear from your error log

E NETWORK [initandlisten] listen(): bind() failed Cannot assign requested address for socket: xxx.xxx.xxx.xxx:27017

There is MongoDB 3.4 Server startup problem resist through bind() of IP, not from your CentOS update.

May be you have mistake of configuration of code. As i am able to see here in one straight line you are writing the bindIp with port number.

As MongoDB BOL documented Here should be separated in systemLog of mongod settings like such as

net:
   bindIp: 127.0.0.1
   port: 27017
