Saya telah berhasil meningkatkan nilai nofile dan nproc untuk pengguna lokal, tetapi saya tidak dapat menemukan solusi yang tepat untuk proses yang diluncurkan oleh systemd. Menambahkan max_open_files ke konfigurasi MariaDB tidak membantu. su - mysql untuk mengubah batas secara manual juga tidak berfungsi (Akun ini saat ini tidak tersedia).
/etc/security/limits.conf
* soft nofile 102400
* hard nofile 102400
* soft nproc 10240
* hard nproc 10240
/etc/security/limits.d/20-nproc.conf (tidak ada file lain yang ada di direktori)
* soft nofile 102400
* hard nofile 102400
* soft nproc 10240
* hard nproc 10240

Sangat menarik bahwa proses yang berbeda (pengguna) memiliki nomor file Max terbuka yang berbeda:
mysql - 1024 4096
apache - 1024 4096
postfix - 4096 4096
Type=notify
perlu atau apakah solusinya bekerja untuk setiap orangType
?
