x-ui面板实现多ip分流出站

xui是最简单的面板，估计没有之一
通过xui实现多ip分流也很简单
创建好入站后直接修改面板设置里的xray配置模板就可以了

模板：

{
  "api": {
    "services": [
      "HandlerService",
      "LoggerService",
      "StatsService"
    ],
    "tag": "api"
  },
  "inbounds": [
    {
      "listen": "127.0.0.1",
      "port": 62789,
      "protocol": "dokodemo-door",
      "settings": {
        "address": "127.0.0.1"
      },
      "tag": "api"
    }
  ],

  "outbounds": [
   {
      "tag": "ip1",
      "sendThrough": "1.1.1.1",
      "protocol": "freedom",
      "settings": {}
    },
    {
      "tag": "ip2",
      "sendThrough": "1.1.1.2",
      "protocol": "freedom",
      "settings": {}
    },
    {
      "protocol": "freedom",
      "settings": {}
    },
    {
      "protocol": "blackhole",
      "settings": {},
      "tag": "blocked"
    }
  ],
  "policy": {
    "system": {
      "statsInboundDownlink": true,
      "statsInboundUplink": true
    }
  },

  "routing": {
    "rules": [
   {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip1",
        "type": "field"
      },
      {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip2",
        "type": "field"
      },
      {
        "inboundTag": [
          "api"
        ],
        "outboundTag": "api",
        "type": "field"
      },
      {
        "ip": [
          "geoip:private"
        ],
        "outboundTag": "blocked",
        "type": "field"
      },
      {
        "outboundTag": "blocked",
        "protocol": [
          "bittorrent"
        ],
        "type": "field"
      }
    ]
  },
  "stats": {}
}

xray的通信原理是inbound-routing-outbound，也就是入站-路由规则-出站
入站节点内容存放在数据库内，不在模板中，数据库与模板共同组合成config.json
要实现多ip分流，主要是通过修改路由规则将入站列表中的节点与不同的出站ip进行连接
所以编辑routing和outbound即可，创建好节点后inbound内容无需修改

outbound(出站)解析

"outbounds": [
    {
      "tag": "ip1",
      "sendThrough": "1.1.1.1",
      "protocol": "freedom",
      "settings": {}
    },
    {
      "tag": "ip2",
      "sendThrough": "1.1.1.2",
      "protocol": "freedom",
      "settings": {}
    },
    ...........
]
"tag":定义此出站配置的标识，内容随意，自己分得清就行
"sendThrough":定义出站ip
routing（路由规则）解析

"routing": {
    "rules": [
      {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip1",
        "type": "field"
      },
      {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip2",
        "type": "field"
      },
      ................
]
"routing": {
    "rules": [
      {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip1",
        "type": "field"
      },
      {
        "inboundTag": [
          "inbound-xxxxx","inbound-xxxxx"
        ],
        "outboundTag": "ip2",
        "type": "field"
      },
      ................
]

• “inboundTag”:入站配置的标识，每个入站列表中的节点都有相对应的inboundTag

xui对inboundTag的命名规则是inbound-节点端口号，比方说一个节点的端口是88888，那么这个节点的inboundTag就是inbound-88888

“outboundTag”:对应出站配置的标识

这个路由规则的意思是说，将inboundtag-xxxxx所在的inbound节点与outbound ip连接。这样就可以实现ip1通过ip1出站，ip2通过ip2出站，或者ip1、ip2通过ip1出站，ip3、ip4通过ip2出站，可以随意组合

直接将routing和outbound里的xx修改好，参照上面模板放在相应的位置，重启服务就好了
