默认情况下，不会为mesos API启用身份验证。安装dcos后，我需要对其进行config mesos api验证。我将为mesosapi设置身份验证，比如：注册框架、运行任务，。。。
问题是在我的配置之后，dcos gui和marathon没有正常工作。
我将DCO配置如下：
mesos环境变量config:path:/opt/mesosphere/etc/mesos master

# Authentication part

MESOS_LOG_DIR=/var/log/mesos

# Framework authentication

MESOS_AUTHENTICATORS="crammd5"
MESOS_AUTHENTICATE_FRAMEWORKS=true
MESOS_AUTHENTICATE_HTTP_FRAMEWORKS=true
MESOS_HTTP_FRAMEWORK_AUTHENTICATORS="basic"
MESOS_ACLS=/opt/mesosphere/etc/acls

MESOS_AUTHENTICATE=true
MESOS_CREDENTIALS=/opt/mesosphere/etc/mesos_credentials_auth.json
MESOS_ROLE=foo

marathon环境变量config:path:/opt/mesosphere/marathon

# authentication section

MARATHON_MESOS_AUTHENTICATION=enabled

# MARATHON_HTTP_CREDENTIALS=marathon:123456

MARATHON_MESOS_AUTHENTICATION_PRINCIPAL=marathon
MARATHON_MESOS_ROLE=foo
MARATHON_MESOS_AUTHENTICATION_SECRET_file=/opt/mesosphere/etc/marathon.secret

marathon环境变量config:path:/opt/mesosphere/metronome

METRONOME_MESOS_AUTHENTICATION_ENABLED=true
METRONOME_MESOS_AUTHENTICATION_PRINCIPAL=metronome
METRONOME_MESOS_ROLE=foo
METRONOME_MESOS_AUTHENTICATION_SECRET_FILE= /opt/mesosphere/etc/metronome.secret

/opt/mesosphere/etc/metronome.secret（包含metronome secret，无新行）

123456

/opt/mesosphere/etc/marathon.secret（包含marathon secret而不换行）

123456

/opt/中层/etc/acls

{
"run_tasks": [
    {
        "principals": {
            "type": "ANY"
        },
        "users": {
            "type": "ANY"
        }
}
],
"register_frameworks": [
    {
        "principals": {
            "type": "ANY"
        },
        "roles": {
            "type": "ANY"
        }
}
]

}
/opt/mesosphere/etc/mesos\u凭证\u auth.json

{
 "credentials" : [
 {
   "principal": "principal1",
   "secret": "secret1"
 },
 {
   "principal": "principal2",
   "secret": "secret2"
 },
 {
     "principal": "marathon",
     "secret": "123456"
     },
 {
     "principal": "metronome",
     "secret": "123456"
     }
  ]
  }

当我启用此配置并停止和启动dcos mesos master时：

systemctl stop dcos-mesos-master.service    
systemctl start dcos-mesos-master.service

systemctl stop dcos-marathon.service
systemctl start dcos-marathon.service

systemctl stop dcos-metronome.service
systemctl start dcos-metronome.service

http://ip/services dcos中的页面无效。我认为它的马拉松认证设置不正确。bcs此地址在启用身份验证配置后工作：
http://ip/service/marathon/v2/deployments?_timestamp=1560449507192
在启用节拍器身份验证后，我在mesos日志中发现以下错误：
