This afternoon, the site two times the machine, the dispatch to Aliyun, found that the reason is the server's CPU 100%. After restarting the server, use the top command to see which processes are consuming so much CPU usage. Stare at a good more than 10 minutes, the main CPU-consuming process has two, one is MySQL, the other is Apache. As you can see from the figure below, MySQL takes up a lot of CPU usage. Apache single Process Although not much, but there are a number of Apache processes at t

1. starting Python from IdieIdle is a python shell,shell meaning "shell", which is basically a way of interacting with the program by entering it. Windows like the cmd window, like the Black Command window of Linux, are all shells and can be used to give commands to the operating system. Similarly, you can use the idle shell to interact with the Pytho. >>> This prompt means: Python is ready, waiting for the Python command to be entered;baishuchaodemacbook-pro:~ xcn$ Python3.5python 3.5.2rc1 (V3.

language version issuesSince the success of UNIX operating system, C language has been widely used, from large mainframe to small microcomputer, have C language active figure, also derived a lot of versions of C language. In the long run, C language will probably become a multi-variant, loose language. A formal language, must have a standard to do, otherwise it will be out of order. In order to change this situation, the United States National Standards Bureau (American Nation Standards Institu

interface:We need to look at how the program itself is organized, that is, how we run the application, what it does throughout its life cycle, what the first line of code it executes, and what the last line of code is.In response, we give the following conclusions:1: Any C # application has a unique main function, which acts as an entry for the entire application;2: In the 12th, 14 lines of code is equivalent to the entire application of the first line and the last line of code;3: Complex appli

. ng-modelTo bind the data model name to text an element, input values are stored in the model. {{text}}This is an expression of the angularjs, that is, the middle of the text is a variable it corresponds to the model name above, the ability to listen to the changes in real-time input values, immediately update the view display. Haha, Angularjs is quite simple, I hope this small note can arouse everyone's interest in Angularjs, and I will continue to update Angularjs's study notes l

(mirrored)Under this architecture, if (RAID 0) A has a disk drive failure, (RAID 0) A is destroyed, of course, RAID 1 will still work, and if (RAID 0) b also has a disk drive failure, (RAID 0) b is destroyed, at this time the two disk drives of RAID 1 is a failure, the entire RAID 1 data is destroyed.Therefore, RAID

this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time. VII. Raid 6 Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability. Next we will introduce several types of combined raid 1. raid01 The total number of disk
