Docker搭建Mesos體系

準備4台伺服器

部署 harbor 安裝docker compose

curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64 -o /usr/local/bin/docker-compose   # 等效上面的指令
chmod +x /usr/local/bin/docker-compose
           

安裝harbor 

wget https://github.com/goharbor/harbor/releases/download/v2.2.1/harbor-offline-installer-v2.2.1.tgz
tar -zxvf harbor-offline-installer-v2.2.1.tgz
配置harbor

cd /usr/local/harbor/    #進入到harbor目錄

cp   harbor.yml.tmpl    harbor.yml

vim harbor.yml   #編輯harbor的配置檔案

#修改以下内容

hostname = 192.168.100.204 #修改harbor的啟動ip，這裡需要依據系統ip設定

port: 80 #harbor的端口,有兩個端口,http協定(80)和https協定(443)

harbor_admin_password = harbor12345   #修改harbor的admin使用者的密碼

data_volume: /harbor/data #修改harbor存儲位置
# https related config
#如果有安全密匙自行配置 沒有就注
# https:

  # # https port for harbor, default is 443

  # port: 443

  # # The path of cert and key files for nginx

  # certificate: /your/certificate/path

  # private_key: /your/private/key/path

安裝harbor

./prepare 
./install.sh 
           

關閉防火牆

systemctl stop firewalld.service
           

設定docker

yum install -y yum-utils
sudo yum-config-manager \ --add-repo \http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl restart docker
           

啟動了docker

設定docker國内鏡像 (harbor 為私有倉庫ip)

sudo mkdir -p /etc/docker
sudo vi /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
,        "insecure-registries": [ "harborip"]

}
sudo systemctl daemon-reload
sudo systemctl restart docker
           

安裝zookeeper(伺服器2)

docker pull zookeeper:latest
docker run --privileged=true -d --name zookeeper --publish 2181:2181 -d zookeeper:latest
           

設定mesos master鏡像(伺服器1)

docker pull mesosphere/mesos-master:1.7.1
           

mesos master配置(伺服器1)

​
docker run -d --net=host \

  --hostname= 本機ip \

設定mesos slave1(伺服器3)

docker pull mesosphere/mesos-master:1.7.1
docker run -d --net=host --privileged \
  --hostname=本機ip \

  mesosphere/mesos-slave:1.7.1 --no-systemd_enable_support \
  --no-hostname_lookup --ip=本機ip
           

設定mesos slave2(伺服器4)

docker pull mesosphere/mesos-master:1.7.1
docker run -d --net=host --privileged \
  --hostname=本機ip \
  -e MESOS_PORT=5051 \

mesos-slave重新開機docker

其他工具性指令

1.啟動docker,指令:systemctl start docker
2.驗證docker是否啟動成功,指令:dockers version
3.重新開機docker,指令:systemctl restart docker
4.關閉docker,指令:systemctl stop docker END
安裝
yum -y install vim*
啟動所有
docker start $(docker ps -a | awk '{ print $1}' | tail -n +2)
所有停止
docker stop $(docker ps -q)
删除 所有
docker rm $(docker ps -aq)
