I wanna make wildfly-domain as a systemd service in centos7
in works by root user but when i start it as wilfly
user after a while it shows error:
java.lang.OutOfMemoryError: unable to create new native threadESC
and stop . even stop service doesn't work .
I tried to change heap-memo and ... but the user is a problem! How can I solve this?
service file is ib wildfly8/bin/init.d/wildfly-init-redhat.sh I tried "ulimit -n " at the top of service script but nothing changed! I have 256Gb Ram and 64core CPU but ....
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
