在部署pyspider分布式時(shí),嘗試連接redis集群配置項(xiàng)為： 'message_queue':'redis://127.0.0.1:6380/db'在啟動(dòng)時(shí)：報(bào)如下錯(cuò)誤[E 170221 09:40:39 tornado_fetcher:529] MOVED 12068 127.0.0.1:6380

經(jīng)查找，得到：因?yàn)閞edis由單節(jié)點(diǎn)變?yōu)榧海鴓ython的redis連接包暫時(shí)還不支持redis集群連接方式，需要更換連接包（redis-py-cluster）。

在安裝完redis-py-cluster之后，依舊報(bào)上面的錯(cuò)誤。

問(wèn)題解答

鏈接 redis 使用的庫(kù)是寫(xiě)在代碼里面的，不是你安裝了就會(huì)切換的。就算你要改代碼，也要確認(rèn) API 是兼容的。
