Why some systemd service on ArchLinux does not work

  |   Source

List failed services


sudo systemctl --failed

I can also use sudo journalctl -b to get the log message when booting all the services. But not very useful.

Find the root cause of failed service


sudo systemctl status service-name

Why my /usr/lib/systemd/system/network-wifi.service does not work

Here is the content of my wifi service


[Unit]

Description=Wireless networkd connectivity (wlan0)

Wants=network.target

Before=network.target

BindsTo=sys-subsystem-net-devices-wlan0.device

After=sys-subsystem-net-devices-wlan0.device



[Service]

Type=oneshot

RemainAfterExit=yes

#EnvironmentFile=/etc/conf.d/network-wireless@wlan0



ExecStart=/usr/bin/ip link set wlan0 up

ExecStart=/usr/bin/wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/yang.conf

ExecStart=/usr/bin/dhcpcd wlan0



ExecStop=/usr/bin/ip addr flush dev wlan0

ExecStop=/usr/bin/ip link set dev wlan0 down



[Install]

WantedBy=multi-user.target

It's because netcfg.service blocks my network-wifi.service.

Solutin is simple:


sudo systemctl disable netcfg

How to start a service as as specific user (mpd, for example)

This is the content of /usr/lib/systemd/system/mpd.service:

After=network.target sound.target



[Service]

ExecStart=/usr/bin/mpd --no-daemon /home/cb/.mpd/config

User=cb



[Install]

WantedBy=multi-user.target
