Compile and install Apache 2.4 In CentOS 6 The httpd-2.4 adds the following new features and new modulesNew features:(1) MPM supports DSO operation and is loaded as needed in the form of modules;(2) event MPM is supported;(3) support asynchronous read/write;(4) Each module and directory can use their respective log levels;(5) configuration of each request;(6) Enhanced expression analyzer;(7) Support for kee

CentOS 7 system has been out for some time, today we look at the CentOS 7 in the VPS to the Lamp environment configuration PHP-FPM process, hope that the article can help you.CentOS 7 has been released and is using Apache 2.4 as the default Apache component. I heard that the Apache 2.4 Event mode is very good, and the supporting mod_proxy_fcgi and PHP has been natively supported by PHP-FPM and good performance, plus Google's mod_spdy need to run in the thread safe Environment, the use of CentOS

Web: http://www.php.net/manual/zh/install.unix.apache2.php This section describes instructions and tips for installing PHP under Apache 2.x on the UNIX platform. Warning We do not recommend that you use threaded MPM in Apache 2 products. Pre-branch mpm, Apache 2.0 and 2.2 default MPM should be used. The reason is that related entries in the FAQ use The apache2

CentOS 7 has been released and uses Apache 2.4 as the default Apache component. I heard that Apache 2.4 Event mode is very good, and the matching mod_proxy_fcgi and PHP has the original support PHP-FPM with the tacit understanding and good performance, plus Google's mod_spdy need to run in the thread safe Environment, instead of CentOS 7 + Apache 2.4 + mariadb + PHP + php-fpm seems to be the logical thing. Because the phpMyAdmin matching PHP-FPM configuration is slightly different from the typic

, and finally we need to configure the Prefork mode of operation. This way in the production environment will be conducive to our flexible application according to their own needs!2 Prefork Working mode implements a non-threaded, pre-distributed Web server, which is the best mpm (multi-processing module) that requires each request to be independent of each other. Each process only processes a single request at a certain time.The 3 prefork mode is resp

use of multiple child processes, each child process has only one thread. Each process can maintain only one connection at a certain time. On most platforms, prefork MPM is more efficient than worker mpm, but memory usage is much higher. Prefork's wireless path design will in some cases be more advantageous than the worker: it can use Third-party modules that do not handle thread safety well, and it is easi

Prefork modeThis multi-path processing module (MPM) implements a non-threaded, pre-derived Web server that works in a similar way to Apache 1.3. It is suitable for systems that do not have a thread-safe library and need to avoid threading compatibility issues. It is the best mpm to require each request to be independent of each other, so that if a request has a problem it will not affect the other request.T

: a Persistent Connection is established. After each resource is obtained, the Connection is not closed. Instead, the Connection continues to wait until other requests are completed. By default, KeepAlive Off is disabled. Disconnection condition: quantity limit: 100 Time Limit: in seconds, the httpd-2.4 supports milliseconds Side effect: for servers with high concurrency traffic, the persistent connection function will use some requests to fail to respond. Compromise: Use a short persistent conn

In prefork mode, multiple sub-processes are used. Each sub-process has only one thread. Each process can maintain only one connection at a specified time. On most platforms, the Prefork MPM is more efficient than the Worker MPM, but the memory usage is much larger. Prefork's wireless program design will be more advantageous in some cases than worker: it can use third-party modules that do not handle thread

The apachectlstatus command is a shortcut for checking the server status. If the output result of the command is not consistently displayed, the available working process is displayed. It is better to increase the value of MinSpareServers or MinSpareThreads (when Apache2.0 adopts thread-based MPM ). You may also need to increase the value of MaxClients.
