這個(gè)錯(cuò)誤: SendBufferToWorker fail. The connections between Gateway and BusinessWorker are not ready

jbking 更新于2018-10-08

今天啟動(dòng)GateWay服務(wù)后征程，想GateWay發(fā)送消息后，報(bào)這個(gè)錯(cuò)誤了

然后，因?yàn)槲沂荕AC系統(tǒng)，我使用sudo dtruss -p 625來看GateWay的進(jìn)程，再發(fā)送一次消息后，然后顯示如下error提示，不知道是哪里出了問題呢？

SendBufferToWorker?fail.?The?connections?between?Gateway?and?BusinessWorker?are?not?ready.
原因
BusinessWorker和Gateway之間的socket鏈接沒有建立，Gateway向BusinessWorker發(fā)送消息失敗。
出現(xiàn)這個(gè)問題的原因一般是start_gateway.php和start_businessworker.php中的
regtisterAddress
設(shè)置錯(cuò)誤或者設(shè)置的不一致。
?
Gateway和BusinessWorker啟動(dòng)后會(huì)根據(jù)
regtisterAddress
設(shè)置的地址(Register服務(wù)地址)注冊(cè)自己，
當(dāng)start_gateway.php和start_businessworker.php中的
regtisterAddress
設(shè)置錯(cuò)誤或者不一致時(shí)，
會(huì)導(dǎo)致Gateway和BusinessWorker無法通訊。
?
start_gateway.php和start_businessworker.php中的
regtisterAddress
地址格式為
Register的IP:端口號(hào)
，
其中端口號(hào)為start_register.php中的監(jiān)聽端口(假設(shè)是1238)，
單機(jī)部署時(shí)，Register服務(wù)為本機(jī)ip 127.0.0.1，則start_gateway.php和start_businessworker.php中的
regtisterAddress
統(tǒng)一為
'127.0.0.1:1238'
。

分布式(集群)部署時(shí)，IP為實(shí)際Register服務(wù)部署的IP(分布式部署時(shí)只需要部署一臺(tái)Register服務(wù)即可，假設(shè)是192.168.1.100)，
則start_gateway.php和start_businessworker.php中的
regtisterAddress
統(tǒng)一為
'192.168.1.100:1238'
。
?
其它原因
業(yè)務(wù)設(shè)置了business_worker->onWorkerStart 或者 Events::onWorkerStart 回調(diào)，并且回調(diào)里有死循環(huán)或者長(zhǎng)時(shí)間阻塞的代碼，致使框架無法執(zhí)行businessWorker與gateway建立連接邏輯，導(dǎo)致報(bào)錯(cuò)。
將死循環(huán)或者長(zhǎng)時(shí)間阻塞的代碼去掉即可恢復(fù)。
