temporary fix for running server-side application on WSL

[justinpan0]

This is a temporary fix for running server-side service on Windows Subsystem for Linux (WSLv1) all versions of Ubuntu.

The original problem of SO_NO_CHECK is likely associated with this WSL issue

As for a temporary fix, check if the Linux is running WSL. If yes, skip the SO_NO_CHECK step.

Note that SO_NO_CHECK supposedly disables Linux kernel to calculate checksum value of all packets received from TDEngine UDP server application. Disabling it might inducing extra error messages, yet this is a quick workaround especially WSL has become one of the most popular platforms thus far.

Also note that there are more issues involving /proc/[pid]/io and taosGetBandSpeed(), and I am actively investigating them as well.

Hit the same error.

Start to install TDEngine...
sed: can't read /etc/inittab: No such file or directory
Couldn't find an alternative telinit implementation to spawn.
cp: cannot stat '%{init_d_dir}/taosd': No such file or directory

ENV:
Windows 10 21H2, WSL2, debian 9
TDengine 2.4.x

@Scythemen we did not officially support WSL due to the systemd lacks. I know someone is working in progress to make systemd on WSL. Right now, you can launch taosd manually as wrokaroud.
