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
