3.1 Configuration item modification

After executing Linkis installation, all configuration items are located in the conf directory, If you need to modify the configuration items, after modifying the ${LINKIS_HOME}/conf/*properties file, restart the corresponding service, For example: sh sbin/linkis-daemon.sh start ps-publicservice. If you modify the public configuration file application-eureka.yml/application-linkis.yml/linkis.properties, you need to restart all services sh sbin/linkis-start-all.sh

3.2 Microservice start and stop

All microservice names are as follows:

├── linkis-cg-engineconnmanager engine management service
├── linkis-cg-engineplugin engine plugin management service
├── linkis-cg-entrance computing governance entry service
├── linkis-cg-linkismanager computing governance management service
├── linkis-mg-eureka microservice registry service
├── linkis-mg-gateway Linkis gateway service
├── linkis-ps-publicservice public service

Microservice Abbreviation:

Abbreviation	Full name in English	Full name in Chinese
cg	Computation Governance	Computing Governance
mg	Microservice Covernance	Microservice Governance
ps	Public Enhancement Service	Public Enhancement Service

# Start all microservices at once:
 
     sh linkis-start-all.sh
 
# Shut down all microservices at once
 
     sh linkis-stop-all.sh
 
# Start a single microservice (the service name needs to remove the linkis prefix, such as: mg-eureka)
 
     sh linkis-daemon.sh start service-name
 
     For example: sh linkis-daemon.sh start mg-eureka
 
# Shut down a single microservice
 
     sh linkis-daemon.sh stop service-name
 
     For example: sh linkis-daemon.sh stop mg-eureka
 
# Restart a single microservice
 
     sh linkis-daemon.sh restart service-name
 
     For example: sh linkis-daemon.sh restart mg-eureka
# View the status of a single microservice
 
     sh linkis-daemon.sh status service-name
 
     For example: sh linkis-daemon.sh status mg-eureka
