+# 关于 Weston 的一些配置
+
+Error running systemd as user - Failed to connect to bus: $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined
+
+```md
+The quick solution
+
+Assuming someuser uses bash as their login shell, add the following exports to ~someuser/.profile [1]:
+
+export XDG_RUNTIME_DIR="/run/user/$UID"
+export DBUS_SESSION_BUS_ADDRESS="unix:path=${XDG_RUNTIME_DIR}/bus"
+
+Then, a user with root/sudo privileges can interact with someuser's systemd by wrapping the command with runuser:
+
+sudo runuser someuser -l -c "systemctl --user enable ipfs"
+sudo runuser someuser -l -c "systemctl --user start ipfs"
+
+runuser someuser -l -c "printenv" can help to troubleshoot these and other exported environment variables.
