## Eureka强制下线 ##

可以通过调用`actuator/service-registry/instance-status`接口，更改实例的状态为OUT\_OF\_SERVICE 。

curl -X POST -H 'Content-Type: application/json'  -d 'OUT_OF_SERVICE' "http://localhost:$1/internal/
    actuator/service-registry/instance-status"

当调用上面的接口之后，实例的状态即被修改为OUT\_OF\_SERVICE

启动后 监控微服务状态 当返回200时启动成功

curl --write-out %{http_code} --silent --output /dev/null http://localhost:$1/internal/actuator/health

.gitlab-ci.yml

- sh $CI_PROJECT_DIR/scripts/deploy-pscm.sh "/data/deploy" "book-sub" "10.187.237.140"
     "-Djava.net.preferIPv4Stack=true -Dspring.profiles.active=dev4" "root" "18288"

注意：当测试环境时推荐参数不传端口号"18288"这样的话就不走强制下线的方法，可以加快启动速度
