Recommend an artifact that should be able to help you. Cloud Helper is a powerful and comprehensive centralized management cloud host software. Not only is it compatible with Linux systems, Windows can also be used. In fact, the use of functions is quite good, because the functions are comprehensive and the installation is simple. Basically, it can be done with one click by a fool. If you add a cloud host in the middle, you need to add a probe for the first time, and then you can basically operate it on the panel. This is quite convenient. I have tried basically all the mainstream clouds and there are no problems, and there are no problems with the system. This is quite worry-free. I won’t say that there are any cloud providers or systems that cannot be used, and I have to find another software. The general functions are as follows: 1. Batch management of multiple cloud hosts; 2. Strong compatibility, compatible with basically all cloud business cloud hosts on the market, and compatible with operating systems; 3. Simple operation, visual interface preview resources, one-click repair, one-click deployment ; 4. You can remotely log in to the FTP desktop of the cloud host and process files on the cloud host; 5. Monitoring and resources also have an alarm function, which is very good, and you don’t have to stare at it; 6. System repair function, this is very practical It is also quite necessary; 7. Free to use. Generally speaking, the functions are quite complete, and there is no need to find another software. A cloud helper software basically meets all needs.

1、如果Yii同时连接多个不同的数据库，那么对比起，这种你除了异步队列来加速没什么好办法，如果是一主多从，Yii在执行事务的时候回始终在主上面执行SQL；
2、同上
3、你可以考虑一主多从的模式，执行事务很快。如果是三个不同的业务系统，并且要求数据必须是实时的话，呵呵。我可以把执行时间假设为0，光算连接时间,不可接受。。。
可以考虑用队列拆分业务。
架构有问题，PHP写入MYSQL，写入哪台mysql不是由PHP去做的，用MYSQL中间件去代理这些操作
