}

六、启动服务

systemctl start nomad
查找Python  json格式：nomad run -output <job>.nomad

七、日志配置

rm -rf /etc/rsyslog.d/nomad.conf
rm -rf /etc/logrotate.d/nomad
echo ':programname, isequal, "nomad" /var/log/nomad.log' >> /etc/rsyslog.d/nomad.conf
echo '& ~' >> /etc/rsyslog.d/nomad.conf
echo '/var/log/nomad.log' >> /etc/logrotate.d/nomad
echo '{' >> /etc/logrotate.d/nomad
echo '    daily' >> /etc/logrotate.d/nomad
echo '    rotate 7' >> /etc/logrotate.d/nomad
echo '    missingok' >> /etc/logrotate.d/nomad
echo '    dateext' >> /etc/logrotate.d/nomad
echo '    copytruncate' >> /etc/logrotate.d/nomad
echo '    compress' >> /etc/logrotate.d/nomad
echo '}' >> /etc/logrotate.d/nomad
重启服务
/bin/systemctl restart nomad
配置开机启动
echo "/bin/systemctl start nomad" >> /etc/rc.local
