On ubuntu centos，
vim /etc/systemd/system.conf
DefaultLimitNOFILE=100000
DefaultLimitNPROC=65535
vim /etc/systemd/user.conf
DefaultLimitNOFILE=100000
DefaultLimitNPROC=65535
Adjust the parameters of the system, set the limits of the startup process,
But I can’t find the corresponding file settings in openwrt,
I have tried a lot, using
cat /proc/pid/limits
None took effect successfully.
