emmm，应某人要求写的。
Sing-box怎么安装就不说了。协议配置也不写了，和本文无关，简单来说一下GeoIP和Geosite的分流。
Sing-box的逻辑是，route里面的rules来判断什么样的规则（rule_set）走怎么样的出口线路（outbounts）。
比如下面这段简单的rules， 如果符合取名（tag）geosite-openai的rule_set，那么走取名（tag）openai的outbouns，tag名字可以随便取，一一对应即可。注意rules从上到下依次判断，有先后顺序（先走为敬）。
"rules": [
{
"rule_set": "geosite-openai",
"outbound": "openai"
},
{
"rule_set": "geosite-bbc",
"outbound": "bbc"
},
{
"rule_set": "geosite-google",
"outbound": "direct"
},
{
"rule_set": "geosite-cn",
"action": "reject"
},
{
"rule_set": "geoip-cn",
"action": "reject"
},
{
"outbound": "direct"
}
],
然后是rule_set。Sing-box可以自行设置很多rule_set，其中的GeoIP/GeoSite数据库地址可以在github上找，我用的是https://github.com/lyc8503/sing-box-rules。配置如下，举例来说，取名（tag）geosite-openai（和上面rules要对应）的rule_set，我选择远程数据库（因为每天在更新），二进制数据库，数据库下载地址https://github.com/lyc8503/sing-box-rules/raw/rule-set-geosite/geosite-openai.srs"，下载方式direct。
"rule_set": [
{
"tag": "geosite-cn",
"type": "remote",
"format": "binary",
"url": "https://github.com/lyc8503/sing-box-rules/raw/rule-set-geosite/geosite-cn.srs"
"download_detour": "direct"
},
{
"tag": "geoip-cn",
"type": "remote",
"format": "binary",
"url": "https://github.com/lyc8503/sing-box-rules/raw/rule-set-geoip/geoip-cn.srs",
"download_detour": "direct"
},
{
"tag": "geosite-google",
"type": "remote",
"format": "binary",
"url": "https://github.com/lyc8503/sing-box-rules/raw/rule-set-geosite/geosite-google.srs"
"download_detour": "direct"
},
{
"tag": "geosite-openai",
"type": "remote",
"format": "binary",
"url": "https://github.com/lyc8503/sing-box-rules/raw/rule-set-geosite/geosite-openai.srs"
"download_detour": "direct"
},
{
"tag": "geosite-bbc",
"type": "remote",
"format": "binary",
"url": "https://github.com/lyc8503/sing-box-rules/raw/rule-set-geosite/geosite-bbc.srs"
"download_detour": "direct"
}
]
},
"experimental": {
"cache_file": {
"enabled": true
}
}
最后是outbounds。以下面举例，比如取名（tag）openai的outbounds，直接走本地IP（比如11.22.33.44），取名（tag）bbc的outbounds，也是走本地IP（比如11.22.33.44），其他流量，直接走名字叫warp的网卡。
"outbounds": [
{
"type": "direct",
"tag": "openai",
"inet4_bind_address": "11.22.33.44"
},
{
"type": "direct",
"tag": "bbc",
"inet4_bind_address": "11.22.33.44"
},
{
"type": "direct",
"tag": "direct",
"bind_interface": "warp"
}
],
写完了。
