First say I find out where the error is, although it is a small mistake, but still have to pay attention to1, the host name of the control node was accidentally modified, then caused the Keystone work is not normal, the message mechanism error. The host name of the control node can be changed back to the original host name.2, an error occurred creating the instance:Look at what Nova-compute.log see:

I want to learn how to create an instance in one of the compiling classes of Python and how to learn python.
Note: I have explained this part of the class by referring to the book "Learning Python.
Create class
The method for creating a class is simple as follows:Copy codeThe Code is as follows:Class Person:
Note that the class name generally starts with an upper
In most cases, beanfactory directly uses the New Keyword to call the constructor to create a bean instance. The class attribute specifies the implementation class of the bean instance. However, this is not the only way to instantiate a bean.
There are three methods to create a bean::
① Call the constructor to
Note: Why do instance users and instance names need to be the same?
There is no instance user option in the instance creation command, but the system finds this user through the Instance name,
The instance folder and file (sqllib)

The code is as follows:

Class Person:Def _ init _ (self, name, lang, website ):Self. name = nameSelf. lang = langSelf. website = websiteSelf. email = "qiwsir@gmail.com" # This property is not passed through the parameter

Create a unique instance for each dependency or each call. This is also the default instance creation method.
Official documentation explanation: configure the component so that every dependent component or call to resolve () gets a new, unique instance (default .)

Before you know how to create an Oracle instance, you must understand the instance definition. When talking about Oracle databases, we are likely to refer to the entire Oracle Database Management System DBMS). But as an Oracle database personnel, we must recognize the major difference between databases and instances-a difference that often confuses non-Oracle sys

For example, we can initialize the data, as follows Public class E

, of course, if you are only temporarily used in the Di container, it is usually not a disaster. So we need to remember the following two points.(1) When the context is injected into the DI container, the use of DbContext is still included, as the Di container does not automatically release it.(2) DbContext is non-thread-safe, even in the Di container, there is nothing to ensure that there is no problem, most of the situation is not problematic, do not worry.Di with dbcontextoptions
Description: For this part of the class, I refer to the "Learning Python" book.
Create Class
The method of creating a class is relatively straightforward, as follows:
The code is as follows:
Class Person:
Note that the name of the class is generally preceded by uppercase letters, which is customary. Of course, if you deliberately do not follow this practice, it is not a problem, but it will give others to read and even their own future reading cause
