In this issue, the editor will bring you about the best practices of Spring Cloud Eureka production configuration. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Based on SpringCloud-Dalston.SR5

Faster service availability can be achieved:

EurekaServer configuration: # time when eureka server refreshes readCacheMap. Note that client reads readCacheMap, which determines how long the readWriteCacheMap cache will be updated to readCacheMap. # default 30seureka.server.responseCacheUpdateInvervalMs=3000#eureka server cache readWriteCacheMap expiration time, this cache will expire only after this time, and will not be updated before expiration. Re-read the registration service information from registry after expiration. Registry is a ConcurrentHashMap. # since evict is enabled, it is not necessary to change this configuration # default 180seureka.server.responseCacheAutoExpirationInSeconds=180# is enabled for active failure, and each active failure detection interval is the default 60seureka.server.eviction-interval-timer-in-ms=3000# service expiration time configuration for 3s#. If you do not receive a heartbeat beyond this time, EurekaServer will remove this instance # Note: EurekaServer must set eureka.server.eviction-interval-timer-in-ms, otherwise this configuration is invalid. This configuration is generally three times the configuration of service refresh time # default 90seureka.instance.lease-expiration-duration-in-seconds=15# service refresh time configuration Active heartbeat every other time # default 30seureka.instance.lease-renewal-interval-in-seconds=5#eureka client refresh local cache time # default 30seureka.client.registryFetchIntervalSeconds=5#eureka client ribbon refresh time # default 30sribbon.ServerListRefreshInterval=1000eureka.instance.preferIpAddress=true# off self-protection eureka.server.enable-self-preservation=falseeureka.client.serviceUrl.defaultZone= http://10.120.242.153:8211/eureka/, Http://10.120.242.154:8211/eureka/EurekaClient configuration: # Service expiration time configuration. If you do not receive a heartbeat within this time, EurekaServer will delete this instance # Note EurekaServer must set eureka.server.eviction-interval-timer-in-ms, otherwise this configuration is invalid, which is generally three times the configuration of service refresh time # default 90seureka.instance.lease-expiration-duration-in-seconds=15# service refresh time configuration Active heartbeat every other time # default 30seureka.instance.lease-renewal-interval-in-seconds=5#eureka client refresh local cache time # default 30seureka.client.registryFetchIntervalSeconds=5#eureka client ribbon refresh time # default 30sribbon.ServerListRefreshInterval=1000eureka.instance.preferIpAddress=true# off self-protection eureka.server.enable-self-preservation=falseeureka.client.serviceUrl.defaultZone= http://10.120.242.153:8211/eureka/, Http://10.120.242.154:8211/eureka/, these are the best practices of Spring Cloud Eureka production configuration shared by the editor.
