Expected behavior Fix this issue by adding the option to enable startup service.

centos7 also encountered this issue. When modifying the max_connections value to be greater than 1024, as long as the system is not restarted, it can be used normally. However, after restarting, it is found that srs cannot start up properly and reports an error.

Check it.

Freamerhxl commented 3 years ago

Ubuntu has the same problem.

I also encountered this issue. I added the SRS startup command to /etc/rc.local, but it resulted in an error when automatically starting up. However, I can manually start it after booting up.

Problem Cause: The official default compilation does not enable epoll and other modes in the st library, but instead uses the select mode. The maximum number of open sockets in this mode is 1024. Therefore, the maximum value of max open files is set to 1024 without limiting it according to the system's settings.

Solution: Run the command "./configure --extra-flags="-DMD_HAVE_EPOLL

I also encountered this problem, it reported an error, system limit to 1024, but my machine is actually not 1024.

winlinvip commented 3 years ago

This is a system issue, guys. Please refer to the Linux manual.

ximenpo commented 2 years ago

The reason for the maximum of 1024 is that the Makefile of st-srs checks whether the file /usr/include/sys/epoll.h exists. If it doesn't exist, the DMD_HAVE_EPOLL macro will not be added, and the default select method will be used. Since select only supports 1024, st-srs sets the setrlimit to 1024.

In the new Ubuntu system, the directory /usr/include/sys has been changed to /usr/include/i386-linux-gnu/sys or /usr/include/x86_64-linux-gnu/sys. This change can cause the mentioned issue. The solution is either to create a symbolic link or modify the Makefile of st-srs to make it compatible.

Ubuntu 20.04 still has issues, and I haven't found a solution yet. Confirm that the system itself is not limited to 1024. Please take a look, thank you @winlinvip.
