Something I want to say before I start blogging.

The landlord was originally mixed with CSDN. When I just graduated, I watched free video tutorials every night, followed the lecturer's step-by-step operation, and then wrote down what I learned in the blog for follow-up reference. This is the original intention of my blog. In the past two years, there are many things in life, and the work is also busy, so I didn't write blog posts. Recently, CSDN found that there are too many restrictions on blog posts, and the previous articles are also quite messy. I want to migrate to ITPUB. Nearly 3 years of technical system used in system operation and maintenance work is also a kind of learning.

Let's first make a list of the technologies used in our work, mainly as follows:

1. Linux: user-related operations, disk-related operations, network-related commands, and further performance tuning

2. Oracle: normal addition, deletion, modification and query, functions, package, stored procedures, awr related operations

3, Python:python is mainly to write scripts, landlord does application operation and maintenance, the development of things is less, recently found that python scripting is more convenient than bat (shell writes well, in the landlord company can increase wages), or to learn.

4. Nginx: the sales system of the operation and maintenance company needs

5. Tuxedo: the background system of the operation and maintenance company needs

The first three items can be mastered, and the latter two understand that life in the landlord's company can be relaxed. The landlord has been looking for video on the Internet for nearly 3 years and found that he has made little progress. I summed up these two days, that is, after watching the video, I did not systematically sort out what I learned, and reviewed it regularly, resulting in many orders not being used for a period of time, and then forgotten. In addition, many commands are only used when learning, and when they find that there is an opportunity to use them at work, because they do not know much about the commands and fear of difficulties, they use the original stupid methods to solve them, and can not achieve the purpose of learning.

The purpose of this blog is to learn the above five items of knowledge, set up a flag here, update a blog post in 2 days, and see how long it will take to learn the above techniques well.
