1. Crawlab 简介：

• 参见： Crawlab：初识分布式爬虫管理平台 Crawlab；

2. 安装 docker

• 安装 docker

sudo dpkg --configure -a
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get install docker-ce

• 配置镜像源

vim /etc/docker/daemon.json

输入如下内容以修改镜像源：

{
"registry-mirrors": ["https://registry.docker-cn.com"]
}

• 安装 docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version  # 查看 docker-compose 版本

• docker 命令

# 启动docker
sudo service docker start

# 停止docker
sudo service docker stop

# 重启docker
sudo service docker restart

# 列出镜像
docker image ls

# 拉取镜像
docker image pull library/hello-world

# 删除镜像
docker image rm 镜像id/镜像ID

# 创建容器
docker run [选项参数] 镜像名 [命令]

# 停止一个已经在运行的容器
docker container stop 容器名或容器id

# 启动一个已经停止的容器
docker container start 容器名或容器id

# kill掉一个已经在运行的容器
docker container kill 容器名或容器id

# 删除容器
docker container rm 容器名或容器id

3. 下载 Crawlab 镜像：

docker pull tikazyq/crawlab:latest

sudo docker pull registry.cn-hangzhou.aliyuncs.com/crawlab-team/crawlab:latest

4. docker-compose 启动 Crawlab
