After reading the Oracle Installation video from instructor Xiao Bu, I found that Oracle installation was really depressing. There is no difficulty, that is, the preparations in the early stage are messy. Therefore, you have compiled an installation script, including modifying the host name, setting kernel variables, and creating users. In this way, you don't have to repeat the same job. The following is my script and Installation notes (Oracle just installed yesterday, there is no time for testing ):

The test is complete. Two mistakes have been modified.
