Redis配置

  • default: 缺省的Redis客户端
  • items: 额外的Redis客户端列表
[sdk.redis]
   [sdk.redis.default]
       host = "127.0.0.1"   <--- redis的服务器
       port = 6379          <--- redis的服务端口
       password = ""        <--- redis的连接密码
       db = 0               <--- redis的连接db
   [[sdk.redis.items]]
       name = "extra1"      <--- 需要通过指定name来区分使用的redis连接
       host = "127.0.0.1"
       port = 6379
       password = ""
       db = 0
   [[sdk.redis.items]]
       name = "extra2"
       host = "127.0.0.1"
       port = 6379
       password = ""
       db = 0

在配置其他Redis连接的时候需要定义在[[sdk.redis.items]]中，同时必须指定name

Redis使用指南
