server

Overview ¶

Package server supplies a way to use ledis as service. Server implements the redis protocol called RESP (REdis Serialization Protocol). For more information, please see http://redis.io/topics/protocol.

You can use ledis with many available redis clients directly, for example, redis-cli. But I also supply some ledis client at client folder, and have been adding more for other languages.

Usage ¶

Start a ledis server is very simple:

cfg := new(Config)
cfg.Addr = "127.0.0.1:6380"
cfg.DataDir = "/tmp/ledis"
app := server.NewApp(cfg)
app.Run()

Replication ¶

You can start a slave ledis server for replication, open slave is simple too, you can set slaveof in config or run slaveof command in shell.

For example, if you start a slave server, and the master server's address is 127.0.0.1:6380, you can start replication in shell:

ledis-cli -p 6381
ledis 127.0.0.1:6381 > slaveof 127.0.0.1 6380

After you send slaveof command, the slave will start to sync master's binlog and replicate from binlog.

HTTP Interface ¶

LedisDB provides http interfaces for most commands(except the replication commands)

curl http://127.0.0.1:11181/SET/hello/world
→ {"SET":[true,"OK"]}

curl http://127.0.0.1:11181/0/GET/hello?type=json
→ {"GET":"world"}
