配置方式
1.创建文件/etc/marathon/marathon，在里面填写Mesos master的参数信息，内容如下：
OPTIONS="--hostname 10.136.157.23 --master zk://10.136.157.23:2181/mesos --zk zk://10.136.157.23:2181/marathon"
2.在目录/usr/lib/systemd/system下创建文件marathon.service，文件内容如下：
[Unit]
Description=Marathon service
After=network.target
Wants=network.target
[Service]
Type=simple
User=root
EnvironmentFile=/etc/marathon/marathon
ExecStart=/home/mesos/marathon/bin/marathon $OPTIONS
PrivateTmp=true
Restart=on-failure
[Install]
WantedBy=multi-user.target
3.启动Marathon
systemctl start marathon
4.设置Marathon开机启动
systemctl enable marathon
遇到的问题
按照上面的方式配置完成后，启动marathon服务，通过
systemctl status marathon
命令也可以看到marathon服务已经启动，但是访问http://{hostname}:8080/确提示“无法访问此网站”
查看启动日志
所以，我就去查看marathon的启动日志，由于是使用systemctl来启动marathon的，日志存放在/var/log/message下，在日志中发现如下异常信息：
