Paying attention to Elastic The Chinese community 、QQ Group 、 In the process of the cluster , More or less, there will be some basic problems . And these problems are not complicated , Most of them are mentioned in official documents , A little more complicated in the official English community 、 There have been similar discussions in the Chinese community .
Basically through Google、bing You can search for answers directly or indirectly .
So the question is ： Why many new friends , I can't find the answer .
I watched and thought for a long time . I think the main problem is , It's not established
Cognition of the whole picture of basic knowledge .
As the saying goes “ Standing higher 、 To see further ”, To be free from the details , Look at the problem from the whole rather than the part , Only by analogy , Find the underlying cause of the problem faster , And then solve the problem .
And sort out the knowledge points through mind mapping , It's about building the whole picture
Faster One of the ways .
therefore , That's why this article .
Cumulative cost 8 Hours +, Made Elasticsearch7.X Learning Roadmap . To be exact, it is aimed at Elasticsearch Sort out related learning , edition 5.X、6.X The same applies .
Because the roadmap is too big , The official account does not support uploading. , Therefore, it is divided into 10 Picture upload .
Full roadmap download address , official account
The background to reply “ Learning route ”, There will be Baidu disk download address to provide .
First of all ： Find the answer from the large and complete official English documents , Instead of looking for... From scattered translated articles .
because ： Many friends have complained about being biased by some one-sided information , And suddenly looking back , The official answer has long been clear .
Premise ： Have a thorough understanding of the overall situation and details of the chapters in the official documents .
second ： More hands-on verification , Not what I thought .
What you think is not necessarily right ,“Talk is cheap. Show me the code." Practice is to make “ I thought ” The only way to shut up .
The skills acquired in practice will form in the long run “ Muscle memory ’, It's not easy to forget .
such as ：logstash Of grok Analytical problem .
Third ： Use... Correctly Google、Stackoverflow、Elastic English community 、Github issues、Elastic The Chinese community .
English key words You can get twice the result with half the effort .
Always believe in ： I'm not a big cow , All the problems I have encountered are a piece of cake , Daniel has already met , And we've given a great solution ; Even the lower version didn't solve , Higher version ES It's all planned .
give an example ：Elasticsearch6.7+ The emergence of ilm Index Lifecycle Management Visualization configuration function .
Fourth ： Log level errors , Check the source context if necessary .
Suggest ： combination Elastic Source code analysis book , Enhance global awareness , Quick to understand .
The fifth ： In addition to the official suggestions, we should check some underlying information .
such as ： Principle of writing 、 Query principle 、 Index allocation principle 、 Routing principle, etc .
Alibaba cloud 、 Tencent cloud's deep blog suggests reading .
from CSDN blink The screenshot you see on , It really works . and 《 The art of questioning ： How to get answers quickly 》 The same is true . Share with everyone .
I am still Elastic Primary school students on the road to practice , The learning roadmap does not cover all the knowledge points , Even part of the logic is not rigorous .
There is a problem , Welcome to . Let's make progress together ！
