wildfly as systemd service
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/wildfly-10.1.0.Final/bin/domain.sh
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/wildfly-10.1.0.Final/
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

Mark Stosberg about 7 yearsInclude the
systemd
.service
file you are having a problem with in your question -
Mehrdad Islamkhah about 7 yearswhat do you mean ? what should i add in where ?
-
Mark Stosberg about 7 yearsYou said you are using
systemd
service. So, there should be a file with the extension.service
in/etc/systemd/system/
. If you aren't using a.service
file, you aren't usingsystemd
. If you are are, paste the contents of that.service
file into your question. -

network.target
might be too early (had problem with that on fast machine with RHEL7); useWants=network-online.target After=network-online.target
so that the interfaces are properly configured on OS side; taken from here: unix.stackexchange.com/questions/126009/… -
Oleg Gritsak about 7 yearsFor network servers it shouldn't matter, but I guess, it will not harm anyway. So, edited my post, thanks.
