Right place for unit is:
/etc/systemd/system/wildfly.service This minimal is ok
[Unit] Description=WildFly application server Wants=network-online.target After=network-online.target [Service] Type=simple User=web Group=web ExecStart=/opt/ Restart=always RestartSec=20 [Install] WantedBy=multi-user.target You should edit only ExecStart field to match your path.
Create user web with
useradd web Also exec by root:
chown -R web:web /opt/ When
systemctl start wildfly systemctl enable wildfly If you get OOMs, inspect your limits
[Service] section of systemd unit, like
LimitFSIZE=infinity LimitCPU=infinity LimitAS=infinity LimitNOFILE=64000 LimitNPROC=64000 or /etc/security/limits.d/ /etc/security/limits.conf
