Springboot集成Redis在開發(fā)環(huán)境中能夠連接使用,部署至linux后拋出異常

部署于某云的Linux服務(wù)器上,一直沒出過問題,今日發(fā)現(xiàn)無法訪問并拋出

經(jīng)過測試redis服務(wù)沒有問題,其他的linux服務(wù)器能夠正常訪問,且在開發(fā)環(huán)境中也能夠正常訪問
redis 配置如下:

spring.redis.database=0
spring.redis.host="host"
spring.redis.port=6379
spring.redis.password="password"
spring.redis.timeout=0
spring.redis.pool.max-active=-1
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0

補(bǔ)充: 從搭建了redis的服務(wù)器查看了一下redis (info命令)的運(yùn)行狀況為正常,且有另外3臺(tái)服務(wù)器鏈接該redis且正常使用,而且這臺(tái)服務(wù)器平時(shí)都正常運(yùn)行,完全猜不到哪里會(huì)有問題,會(huì)不會(huì)問題在阿里云上?

再次補(bǔ)充
從無法鏈接的服務(wù)器 telnet Redis服務(wù)器顯示被拒絕而且我關(guān)閉了所有防火墻,且由其他服務(wù)器正常使用該Redis 這個(gè)問題實(shí)在讓人費(fèi)解啊現(xiàn)在只能使用其他服務(wù)器代替該服務(wù)器了很無語

從異常看是redis無法連接導(dǎo)致，超時(shí)java.net.SocketTimeoutException: connect timed out
手動(dòng)檢測部署應(yīng)用服務(wù)器能否連接redis.

telnet <host> 6379

如果沒telnet，可使用python

$ python
...                                                                                                                                                                                                         
>>> import socket                                                                                                                                                                                                                                                              
>>> conn=socket.create_connection(('<host>',6379))   
>>>                                               //如果沒出現(xiàn)錯(cuò)誤說明可以連接上

看報(bào)錯(cuò)是redis鏈接池出問題了？開啟鏈接池，鏈接使用結(jié)束后沒有放回，導(dǎo)致泄漏，慢慢累積鏈接池中的鏈接最后都被占用導(dǎo)致從連接池中獲取不到鏈接了。
其他應(yīng)用鏈接redis正常，說明不是redis問題了。

應(yīng)用運(yùn)行一段時(shí)間正常，說明應(yīng)用鏈接redis也沒問題。你先重啟看下是否可以解決此問題。
如果不報(bào)錯(cuò)了，十有八九就是鏈接使用后沒有關(guān)閉導(dǎo)致的。然后就去找哪里導(dǎo)致的鏈接泄漏吧。
如果還是報(bào)鏈接redis失敗就看看是不是應(yīng)用服務(wù)器不通redis服務(wù)了，防火墻之類的限制住了？
