找不到运行服务实例

Question

我正在使用 Cloudify 2.7 和 OpenStack Icehouse。

我已经使用以下应用程序 grooxy 在负载均衡器 apache 后面部署了一个 tomct 服务：

application {

name="servizio_tomcat"

service {
    name = "LB_apache"
}
service {
    name = "tomcat"
    dependsOn = ["LB_apache"]
}
}

现在，负载均衡器 (LB) 已成功启动，而 tomcat 服务 returns 以下日志：

2015-07-10 15:40:00,705 vm1.tomcat [1] INFO [org.cloudifysource.usm.launcher.DefaultProcessLauncher] - tomcat_install.groovy: Tomcat installazione terminata 2015-07-10 15:40:01,039 vm1.tomcat [1] INFO [org.cloudifysource.usm.launcher.DefaultProcessLauncher] - Command exited with value: 0 2015-07-10 15:40:01,239 vm1.tomcat [1] INFO [org.cloudifysource.usm.USMEventLogger.vm1.tomcat] - vm1.tomcat-1 INSTALL completed, duration: 69.2 seconds 2015-07-10 15:40:01,240 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Waiting for dependencies 2015-07-10 15:40:01,240 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Waiting for dependency: vm1.LB_apache 2015-07-10 15:40:01,241 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Waiting for PU: vm1.LB_apache 2015-07-10 15:40:01,242 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Waiting for PUI of service: vm1.LB_apache for 1799998 Milliseconds 2015-07-10 15:40:02,246 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Timeout ended. processing unit vm1.LB_apache found result is false 2015-07-10 15:40:02,246 vm1.tomcat [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Could not find a running instance of service: vm1.LB_apache.

--已编辑-- 另外，成功启动了LB_apache负载均衡服务，如下：

2015-07-23 10:56:57,743 vm1.LB_apache [1] INFO [LB_apache-stdout] - LB_apache_Start.groovy: Finished start of LB_apache.

有人可以帮我理解那个警告吗？谢谢

Answer 1

此日志文件仅包含 INFO 日志，不包含错误。日志行仅表明 Apache 负载平衡器实例尚未启动。 tomcat 实例在负载均衡器实例上配置为 'depend'。因此，在负载均衡器启动并完成向 Cloudify 集群的注册之前，tomcat 不会启动。

tomcat 服务将一直等待，直到 Apache 实例启动。
