Thank you for your reply!

I adopted the official version 7.6 mini of CentOS, and manually upgraded the kernel to 4.20.3.

CentOS 7.6 comes with systemd. For the first time, I tried to use the systemd method recommended by the official document. When I executed the command “systemctl --user start docker”, the error “Failed to get D-Bus connection: No such file or directory” was reported.

Looking back, it is found that “/usr/bin/dockerd-rootless-setuptool.sh install” is executed, and it prompts “[INFO] systemd not detected, dockerd-rootless.sh needs to be started manually”.

Checking the “dockerd-rootless-setuptool”.sh script found a setting for SYSTEMD

if systemctl --user show-environment > /dev/null 2>&1; then
        SYSTEMD=1
fi

When I manually execute “systemctl --user show-environment” under the general user, it prompts the error message “Failed to get D-Bus connection: No such file or directory”

At this time, I considered deploying through the “Without systemd” method, but it is not very smooth.
