MCF:无法设置mysql服务

Question

在OSX10.7.4的VMWare融合5.0.1上运行MCF。VMC版本为0.3.19

maguro:Desktop darrellberry$ vmc create-service
1: redis
2: mongodb
3: postgresql
4: mysql
5: rabbitmq
Which service would you like to provision?: 4
Creating Service [mysql-eaca7]: 
Error 503: Unexpected response from service gateway

在MCF实例上，/var/vcap/sys/log/mysql_gateway/mysql_gateway.log显示：

[2012-09-06 09:14:56] mysql_gateway - 3249 c74f 72e9   INFO -- Sending info to cloud controller: http://api.xx.cloudfoundry.me/services/v1/offerings

[2012-09-06 09:16:05] mysql_gateway - 3249 c74f 72e9   WARN -- Request timeout in 10 seconds.

(这里混淆了urls和电子邮件--日志中的urls和电子邮件看起来是正确的)

这是100%可重复的。然而，我可以提供其他类型的服务(postgresql、rabbitmq等)而不会出错。感谢大家的帮助。

无论出于什么原因，mysql节点都没有启动(每个服务都有一个节点和一个网关)。查看/var/vcap/sys/log/mysql/mysqld.err.log的最后100行，看看是否有什么明显的地方。

更好的是，通过安装telnet并连接到VM本身上的端口3306来仔细检查服务是否正在运行；

sudo apt-get install telnet
telnet localhost 3306

如果连接立即打开，而你做了类似这样的事情；

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
<
5.1.54-rel12.5?xaZ!5%Wh?'%&,Ks%Xn@4"^]

那么mysql肯定在运行。mysqld也应该出现在进程列表中。
