In fact, what is better than what is, Is YY, when the master fight, is optimized to the BT level to take out the test. You nginx is awesome, but my squid is very strong after optimization, and then a sweeping monk said, I will not lose you with Apache performance ...... When using Apache as the front-end, you must note that the proxy module must be loaded. What you load depends on what you need. I have see

The image is uploaded to the server in the background, but how is it displayed on the front-end? is it a code problem? If (empty ($ _ GET [submit]) { ?> } Else { $ Path = "uploadfile/"; // Upload path // Echo $ _ FILES ["filename"] ["type"]; If (! File_exists ($ path )) { // Check whether the folder exists. if not, create the folder and grant the highest perm

This article describes the system optimization, mainly for the front-end and background of these two aspects (the background of the main SQL statements and data storage optimization), the following we will introduce some optimization techniques and experience. Skills: 1. How to detect inefficient statements? Under MySQL, set the--log-slow-queries=[file name in

is a subquery that is raised by exists or not exists. exists returns TRUE if the subquery returns any rows, otherwise false is returned Store query ResultsWe can store the query results uniformly in a new data table, without needing to be entered in a single line. Below, first create a "Product Classification" empty table Then, query all records for the Tdb_goods table, and GROUP by category Write grouped results to the "Product Classification" datasheet INSERT [into] tbl_name [(col_name),...)]

trigger bar, first create a custom function, the function will access the port of the program you need to callback, and then invoke the function inside the trigger----I said is the MySQL trigger, MySQL DIY function can be directly written in C, convenient and fast, PHP installed a multi-threaded module, listening to two ports, One for interacting with the front-end WebSocket, one for receiving data sent by

Http://www.ooso.net/archives/545 In the mail group, someone asked me if I could run multiple hiphop-PHP compiled programs on the same port. It is also reasonable to think about it. If a server runs multiple sites, port 80 must be used. When you lease servers together, this demand is even stronger. At that time, the solution I came up with was to set up a proxy such as nginx in front, and the compiled prog

How the backend uses get or post data from the database to be packaged into JSON:Need to download the JSON jar package, here are: http://download.csdn.net/detail/zhangy0329/607838Connection ct =NULL; Statement SM=NULL; ResultSet RS=NULL; Try{class.forname ("Com.mysql.jdbc.Driver");//connect to MySQL databasect = drivermanager.getconnection ("jdbc:mysql://localhost:3306/database name? useunicode=truecharacte

When we deploy the server, we need to do a startup script to make it easy for us to start/Shut down the server.Here I give a pro-test script file, The script is a script to start node, the principle is to start the execution of the start command, the resulting number is written to the file, and then stop the time to remove the PID from the file, and then kill it. Finally, the process is erased. #!/bin/sh node_env=production daemon= "Nodecluster.js" NA

When outputting JSON data on the server, the Time field is output in a certain format, and Fastjson supports two ways:1. Using the Json.tojsonstringwithdateformat method2.json.tojsonstring method to increase Serializerfeature.writedateusedateformat parametersThe disadvantage of the first method is that if Json.deffault_date_format = "Yyyy-mm-dd hh:mm" is not called when deserializing; Set the time format, the deserialization will fail!Java
