|
|
//
|
|
// redis://[username:password@]host[:port][/database][?[option=value]*]
|
|
// rediss://[username:password@]host[:port][/database][?[option=value]*]
|
|
// redis+socket://[username:password@]path[/database][?[option=value]*]
|
|
// redis+sentinel://[password@]host1 [: port1][, host2 [:port2]][, hostN [:portN]][/ database][?[option=value]*]
|
|
// redis+cluster://[password@]host1 [: port1][, host2 [:port2]][, hostN [:portN]][/ database][?[option=value]*]
|
|
//
|
|

|
|
// addrs=127.0.0.1:6379 db=0
|
|
// network=tcp,addr=127.0.0.1:6379,password=macaron,db=0,pool_size=100,idle_timeout=180
