centos7部署crawlab爬虫管理平台遇到的一些问题

一、centos7安装docker

yum install docker -y

二、centos7自带的python2.75升级到python3

yum install centos-release-scl -y
yum install rh-python36
scl enable rh-python36 bash
#pip install --upgrade pip
yum -y install python-pip

三、修改docker配置文件

文件：/etc/docker/daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}

四、拉取镜像:

docker pull tikazyq/crawlab:latest

五、安装docker-compose

pip install docker-compose
#验证安装
#docker-compose ps

六、配置启动文件；
docker-compose.yml

    ports:    
      - "8080:8080" # frontend port mapping 前端端口映射
    depends_on:
      - mongo
      - redis
    # volumes:
    #   - "/var/crawlab/log:/var/logs/crawlab" # log persistent 日志持久化
  worker:
    image: tikazyq/crawlab:latest
    container_name: worker
    environment:
      CRAWLAB_SERVER_MASTER: "N"
      CRAWLAB_MONGO_HOST: "mongo"
      CRAWLAB_REDIS_ADDRESS: "redis"
    depends_on:
      - mongo
      - redis
    # environment:

六、启动

docker-compose up
#启动后会自动下载各种组件

七、访问：

宿主机IP:8080 访问平台，默认账号密码：admin/admin

八、更新

# 关闭并删除 Docker 容器
docker-compose down

# 拉取最新镜像
docker pull tikazyq/crawlab:latest

# 启动 Docker 容器
docker-compose up -d
