boot节点上操作

生成genconf目录

# mkidr /opt/mesosphere/genconf && cd /opt/mesosphere/genconf

设置自定义安装配置

配置路径 /opt/mesosphere/genconf/config.yaml

# cat config.yaml 
agent_list:
    - 192.168.22.192
    - 192.168.22.193
bootstrap_url: http://192.168.22.190:8080
cluster_name: test
exhibitor_storage_backend: static
master_discovery: static
master_list:
    - 192.168.22.191
resolvers:
    - 8.8.4.4
    - 8.8.8.8
ssh_port: 22
ssh_user: centos
dcos_overlay_enable: true
dcos_overlay_mtu: 9001
dcos_overlay_config_attempts: 6
dcos_overlay_network:
      vtep_subnet: 44.128.0.0/20
      vtep_mac_oui: 70:B3:D5:00:00:00
      overlays:
        - name: dcos
          subnet: 9.0.0.0/8
          prefix: 26
        - name: dcos-1
          subnet: 192.168.0.0/16
          prefix: 24

构建IP Detect脚本

配置路径 /opt/mesosphere/genconf/ip-detect

# cat ip-detect 
#!/usr/bin/env bash
set -o nounset -o errexit
export PATH=/usr/sbin:/usr/bin:$PATH
echo $(ip addr show ens32 | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | head -1)

下载DC/OS Installer

# cd /opt/mesosphere
# curl -O https://downloads.dcos.io/dcos/stable/dcos_generate_config.sh

生成自定义集群安装包

# bash dcos_generate_config.sh

通过HTTP发布serve目录

通过Nginx容器镜像或其它手段将./genconf/serve/目录通过HTTP开放给待装节点访问。

# docker run -d -p 8080:80 -v /opt/mesosphere/genconf/serve:/usr/share/nginx/html:ro nginx

master-01节点操作

安装master节点

# mkdir /tmp/dcos && cd /tmp/dcos
# wget http://192.168.22.190:8080/dcos_install.sh
# bash dcos_install.sh master

---

node-01 node-02 节点上操作

安装agent节点

# mkdir /tmp/dcos && cd /tmp/dcos
# wget http://192.168.22.190:8080/dcos_install.sh
# bash dcos_install.sh slave
