查看雷池的服务架构图(示意图较老,参考为主)。最上面虚线框住的是数据流,也就是访问业务服务器的流量数据的流动情况。中间框起来的部分是雷池的各个服务。
各个容器和服务说明:
名称 | 定义 | 详情 |
---|---|---|
safeline-mgt | 管理容器(管理端) | 接收管理后台行为,向其他服务或容器推送消息 |
safeline-detector | 检测容器 | 执行检测的容器,从 Tengine 进入的流量会转发到该节点检测 |
safeline-mario | 日志容器 | 记录与统计恶意行为的节点 |
safeline-tengine | 网关 | 转发网关,有简单的过滤功能,基于nginx实现 |
safeline-pg | 关系型数据库 | 存储攻击日志、保护站点、黑白名单配置的数据库 |
safeline-luigi | 数据统计服务 | 统计qps等信息 |
safeline-fvm | 规则处理容器 | 将规则传递到检测容器 |
safeline-bridge | 支持云托管 | 通讯的桥接器 |
对于后台管理人员,可以直接通信的节点为管理服务 safeline-mgt
,该节点负责:
safeline-detector
推送postgres
数据库,向后台管理人员返回日志、统计、当前配置等用于设置 compose.yaml
要引用的环境变量
echo "SAFELINE_DIR=$(pwd)" >> .env # 设置当前路径为雷池社区版的根路径
echo "IMAGE_TAG=latest" >> .env # 设置镜像的 tag
echo "MGT_PORT=9443" >> .env # 管理容器服务使用的端口
echo "POSTGRES_PASSWORD=$(LC_ALL=C tr -dc A-Za-z0-9 </dev/urandom | head -c 32)" >> .env # /dev/urandom是一个很长的随机数文本,tr -dc 命令用于删除非字母、非数字的字符,用于生成随机的 postgres 密码
echo "SUBNET_PREFIX=172.22.222" >> .env # 定义 docker 虚拟网卡的子网前缀
用于启动多个容器
