Hello @liufunyu

  1. Clear out the php sessions issue unless you are running multiple php versions. To be sure try this:
# start here copy line bleow me
rm -f /var/lib/lsphp/session/lsphp71/* && rm -f /var/lib/lsphp/session/lsphp72/* && rm -f /var/lib/lsphp/session/lsphp73/* 
# then copy line below me
rm -f /var/lib/lsphp/session/lsphp74/* && rm -f /var/lib/lsphp/session/lsphp80/* && rm -f /var/lib/lsphp/session/lsphp81/*
  1. Check this out MariaDB / MySQL Tweaks As Default & Option

Basically run nano /etc/my.cnf use the keyboard shortcut CTRL+W to search for skip-name-resolve and comment it out. Restart mariadb systemctl restart mysqld

  1. Stop using Redis and opt for Memcached for caching and persistence key storage if you are using it
