安装

下载对应平台的软件包，解压即可

流程

注意因为配置是json 格式，所以关于json 注释的信息都应该删除，否则配置会有问题

• 基本配置 conf/bfe.conf

hostRuleConf = server_data_conf/host_rule.data      #域名规则配置文件

routeRuleConf = server_data_conf/route_rule.data    #分流规则配置文件

clusterConf = server_data_conf/cluster_conf.data    #集群配置文件

 

clusterTableConf = cluster_conf/cluster_table.data  #集群实例列表配置文件

gslbConf = cluster_conf/gslb.data                   #子集群负载均衡配置文件

• 域名配置（产品线，租户）conf/server_data_conf/host_rule.data

 {

    "Version": "init version",

    "DefaultProduct": null,

    "Hosts": {

        "jenkinsapp":[

            "mydemoapp.rongfengliang.com"

        ]

    },

    "HostTags": {

        "jenkinsdemo_product":[

            "jenkinsapp"

        ]

    }

}

• 集群信息配置 conf/server_data_conf/cluster_conf.data

{

    "Version": "init version",

    "Config": {

        "cluster_demo_static": {                    // 集群cluster_demo_static的配置

            "CheckConf": {                          // 健康检查配置

                "Schem": "http",

                "Uri": "/",

                "Host": "mydemoapp.rongfengliang.com",

                "StatusCode": 200

            }

        },

        "cluster_demo_dynamic": {                   // 集群cluster_demo_dynamic的配置

            "CheckConf": {                          // 健康检查配置

                "Schem": "http",

                "Uri": "/",

                "Host": "mydemoapp.rongfengliang.com",

                "StatusCode": 200

            }

        }

    }

}

• 集群实例配置 conf/cluster_conf/cluster_table.data

{

    "Version": "init version",

    "Config": {

        "cluster_demo_static": {         // 集群 => 子集群 => 实例列表

            "demo_static.all": [{        // 子集群demo_static.all

                "Addr": "10.15.0.15",      // 实例地址:10.0.0.1

                "Name": "static.A",      // 实例名:static.A

                "Port":50658,            // 实例端口:8001

                "Weight": 1              // 实例权重:1

            }]

        },

        "cluster_demo_dynamic": {

            "demo_dynamic.all": [{

                "Addr": "10.15.0.80",

                "Name": "dynamic.A",

                "Port":80,

                "Weight": 1

            }]

        }

    }

}

• 子集群负载均衡 conf/cluster_conf/gslb.data

{

    "Hostname": "",

    "Ts": "0",

    "Clusters": {

        "cluster_demo_static": {       // 集群 => 子集群权重

            "GSLB_BLACKHOLE": 0,       // 黑洞的分流权重为0，表示不丢弃流量

            "demo_static.all": 100     // 权重为100，表示全部分流到demo_static.all

        },

        "cluster_demo_dynamic": {

            "GSLB_BLACKHOLE": 0,

            "demo_dynamic.all": 100

        }

    }

}

• 分流规则 conf/server_data_conf/route_rule.data

{

    "Version": "init version",

    "ProductRule": {

        "jenkinsdemo_product": [    // 产品线 => 分流规则

            {

                // 以/static开头的path分流到cluster_demo_static集群

                "Cond": "req_path_prefix_in(\"/cube\", false)",  

                "ClusterName": "cluster_demo_static"

            },

            {

                // 其他流量分流到cluster_demo_dynamic集群

                "Cond": "default_t()",

                "ClusterName": "cluster_demo_dynamic"

            }

        ]

    }

}

启动

./bfe -c ../conf -l ../log

测试

• 访问

// 静态信息

curl -H "host: mydemoapp.rongfengliang.com" "http://127.0.0.1:8080/cube/index.html"  

// 动态信息

curl -H "host: mydemoapp.rongfengliang.com" "http://127.0.0.1:8080"
