MongoDB - can't run because of SELinux is preventing mongod from open access on the file /proc/sys/net/ipv4/tcp_fastopen

Question

After install, my mongod server was running well. I have created user and restart the server without issue.

But now when modified gonfi file by adding 0.0.0.0 to bindip, server wont restart. Error message are

Jan 24 11:59:53 localhost.localdomain setroubleshoot[4656]: failed to retrieve rpm info for /proc/sys/net/ipv4/tcp_fastopen

                                                            If you believe that mongod should be allowed open access on the tcp_fastopen file by default.
                                                            Then you should report this as a bug.
                                                            You can generate a local policy module to allow this access.
                                                            Do
                                                            allow this access for now by executing:
                                                            # ausearch -c 'mongod' --raw | audit2allow -M my-mongod
                                                            # semodule -X 300 -i my-mongod.pp

ausearch -c 'mongod' --raw | audit2allow -M my-mongod

semodule -X 300 -i my-mongod.pp

does not solved the problem.

Mongodb doc say that version 4 activate by default use of tcp_fastopen I can't find out how to apply semanage permissive to use tcp_fastopen.

Thanks in advance

Answer 1

Verify your operating system is supported by MongoDB.

Install a vanilla version of your operating system, do not change any settings, use published MongoDB documentation to install MongoDB and get it working.

Identify differences between your current installation and the vanilla installation.

Update your question with findings.
