I started to write this post before weeks ago and finally publish it even if it's not totally finish. it is just a little feedback about tuning a full lamp server with some user traffic and services load. important thing to notice is that all stuff in this post isNot the solution. You will probably have to tune little more for adapt all this to your personal server usage, server load, development architecture. so, use those tips as a kind of inspirat

, this is also very normal, after all, nothing is perfect, we can only make full use of their strengths to solve their own problems, rather than hope to rely on a solution to solve all problems once and for all. This section will do a pros and cons analysis of the above major scenarios, for everyone to choose the process of reference.1.

This article introduces 10 MySQL Performance tuning methods. each method is very detailed and practical. For more information, see MYSQL, which is the most popular WEB backend database. WEB development languages have developed rapidly recently. PHP, Ruby, Python, and Java have their own characteristics. although NOSQL has been mentioned more recently, I believe m

MySQL performance tuning and Architecture design--9th chapter The performance optimization of MySQL database schema designPreface: Many people think that performance is optimized in the process of writing code (program code or database code), in fact, this is a very big misunderstanding. The real impact of the most performance of the part is in the design has bee

101 MySQL tuning and optimization skills, MySQL skills MySQL is a powerful open-source database. With more and more database-driven applications, people have been pushing MySQL to its limit. Here are 101 tips for adjusting and optimizing

It is important to note that this method is only built on top of MySQL 5..1, as follows: First, let's look at the default output, the script is as follows: like ' Log_output '; As you can see, the default output here is file, and we change this to table. set global log_output='TABLE'; Select Sleep (ten); Select * from Mysql.slow_log; i

If you are backing up with MySQL dump, back up the binary logs at the same time-ensure that the replication process is not interrupted. 91. Do not trust backup of LVM snapshots-you may create inconsistent data that will cause problems in the future. 92. M

example illustrates: Use test; #创建表 int, b varchar (5)); #插入数据 INSERT INTO testonerow values (1,'111') We're simply going to execute a script Explain select B from Testonerow As you can see here, you simply get the data through the table scan (all), without any indexes to refine the query. Let's create an index CREATE INDEX Index_b on Testonerow (b) As you can see, this is a simple example of optimizing T-SQL by creating an index. Conclusion This

In general, MySQL optimization can be divided into two levels: one is Optimization at the MySQL level, such as SQL rewriting, index addition, and configuration of various MySQL parameters; the other layer is the operating system and hardware.
