I tried following command and resolved the problem:

java -Dspring.profiles.active=mysql -Dloader.path=./libs -Dalpha.server.host=0.0.0.0 -Dalpha.server.port=7080 -Dserver.port=6090 -Dalpha.cluster.address=localhost:7080 -D"spring.datasource.url=jdbc:mysql://localhost:3306/saga?useSSL=false&serverTimezone=Asia/Shanghai&characterEncoding=utf8" -Dspring.datasource.username=root -Dspring.datasource.password=root -jar alpha-server-0.4.0-exec.jar

Some problems I met when I try to running alpha, I attached to the mail. Some configurations are not mentioned in docs, so it takes quite  an effort to fix it.

Now I meed another problem, after I changing omega from 0.3.0 to 0.4.0, I got following error ( demo is here: https://github.com/huaweicse/cse-java-chassis-samples/tree/master/HouseAppWithSpringBoot2).
