LNMP source code compilation installation php-5.5.32 instance

This article mainly and everyone to share LNMP source code compiled installation php-5.5.32 instance, hope to help everyone.

1 What is CGI

• The CGI is all called "Universal Gateway Interface" (Common Gateway Interface), for HTTP
  A tool that the server communicates with the program services on other machines, and the CGI program must be running on a network server.

• The main disadvantage of the traditional CGI interface approach is poor performance, because every time the HTTP server encounters a dynamic program, it needs to perform parsing by restarting the parser, after which the result is returned to the HTTP server. This is almost unusable when dealing with high concurrent accesses, so fastcgi is born. In addition, the traditional CGI interface security is also very poor, it is now very rarely used.

2 What is fastcgi

• FastCGI is a scalable, high-speed interface for communicating between HTTP servers and dynamic scripting languages (under Linux, the FastCGI interface is the socket, which can be a file socket or an IP socket), The main advantage is separating the dynamic language from the HTTP server. Most popular HTTP servers support fastcgi. including Apache, Nginx, and lighttpd.

• At the same time, FASTCGI is supported by many scripting languages, and one of the more popular scripting languages is PHP. The FastCGI interface uses the C/s (client/server) architecture, which separates the HTTP server from the script resolution server and initiates one or more scripts to parse the daemon on the script resolution server. When the HTTP server encounters a dynamic program, it can be delivered directly to the fastcgi process to execute, and the resulting results are returned to the browser. This approach allows the HTTP server to handle static requests exclusively, or to return the results of a dynamic script server to the client, which greatly improves the performance of the entire application system.

3 operation Principle of Nginx fastcgi

Nginx does not support direct invocation or parsing of external dynamic programs, and all external programs (including PHP) must be called through the FastCGI interface. FastCGI interface under Linux is the socket, in order to invoke the CGI program, also need a fastcgi wrapper (can be understood as the program used to start another program), the wrapper is bound to a fixed socket, such as a port or file socket. When Nginx sends the CGI request to the socket, through the FastCGI interface, the wrapper receives the request, and then derives a new thread, which invokes the interpreter or the External program processing script to read the returned data; Wrapper the returned data through the FastCGI interface, along the fixed socket to nginx; Finally, Nginx sends the returned data to the client, which is the whole process of nginx+fastcgi. The detailed process is as follows.

4 lnmp PHP (Fastcgi) Service installation Preparation

4.1 Check the installation of Nginx and MySQL

[Root@web01 ~]# netstat-lntup |egrep "nginx|mysql" tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      1568/ mysqld         TCP        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      1694/nginx          [root@web01 ~]# cat/etc/ Redhat-release CentOS Release 6.9 (Final) [root@web01 ~]# uname-r2.6.32-696.el6.x86_64[root@web01 ~]# uname-mx86_64

4.2 Check the Lib libraries required to install PHP

# PHP program in the development and operation will call some such as zlib, GD and other libraries, so you need to confirm whether the Lib library is installed, execute the command as follows:

Rpm-qa zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-develrpm-qa freetype-devel libpng-devel Gd-devel Libcurl-devel Libxslt-devel

Hint: Libjpeg-turbo-devel is the new name of the early Libjpeg-devel, Libcurl-devel is the new name of the early curl-devel.
Each lib will generally have a corresponding "-devel" named Package,the corresponding "-devel" package, the corresponding LIB package will be installed automatically, such as installation of Gd-devel will install GD.

# These LIB libraries are not required to be installed, but they are usually installed in the current enterprise environment. Otherwise, the PHP program runs a problem, such as the verification code cannot be displayed.
