Common parameters for CGI installation:

--enable-fpm # Hit PHP-fpm  This parameter is only available after patching, CGI The startup program installed in the mode 

--enable-fastCGI # Support fastcgi Mode startup PHP

--enable-force-CGI-redirect # Start in redirected mode PHP

--with-ncurses # Support ncurses  Dynamic library of screen rendering and graphic interaction function based on text terminal 

--enable-pcntl #freeTDS What needs to be used may be links mssql  Just use it 

--with-mcrypt #mcrypt Extension of algorithm

--enable-sigchild

--enable-sysvsem

--enable-sysvshm

--enable-zend-multibyte # Support zend Multibyte of 

--enable-mbregex

--enable-wddx

--enable-shmop

--enable-soap

Remarks: Extensions that need to be installed separately

1. gd library.
2. Extension of ming.
3. Extensions to mhash and mcrypt

1 > After -with-apxs2=/usr/local/apache/bin/apxs is specified, do not activate-enable-fpm and-enable-fastCGI, which loads PHP in the mode of php module.

2 > Mysql After compiling Mysql to develop library, you don't have to specify the path of mysql.

3 > PHP compilation has a basic dependency relationship. To compile PHP, you need to install XML extension first, because php5 core opens XML support by default. Other basic libraries need:

4 > GD - > zlib, Png, Jpg, if you need to support others, you still need to compile the extension library according to the actual situation, and ttf library needs the support of freetype library.

5 > --enable-magic-quotes is an extremely unrecommended parameter. Of course, if you need PHP to do the bottom work for you, it doesn't really solve the problem thoroughly.

6 > -with-openssl, openssl library required.

The mysqli is the MySQL driver provided by the MySQL team and has many practical functions and typical features. However, it is not the best choice for MySQL on PHP platform, and PDO has been proved to be a simple, highly concurrent, and easy to create and recycle standard interface. However, PDO also experienced the problem of memory overflow before 5.3. After 5.3, when reading LOB resources of Oracle, if the memory is not limited, the memory will still overflow.

If it is a product mode, such as pear, shmop, ftp, etc., it is not recommended to use it. What they want to do is to use C/C + +, Java, and even other scripting languages, which have good and fast choices, and need not be limited to using PHP. Unfamiliar class libraries and infrequent libraries are not recommended. magic-quote, session.auto_start, PHP server information, PHP error reporting information, etc. should be closed at the first time after compilation to avoid exposing server information.

PHP corresponds to Web Server mode, Module, fastcgi and fpm only need one mode, and the server is not your experimental field. fastcgi can choose Nginx and lighttpd. In fact, Nginx also uses spwan-fcgi of lighttpd to manage fcgi process. fpm uses PHP itself to manage multiple processes, somewhat like a back-end agent. Whatever the pattern, you should do process and thread tuning on the release server, and do enough performance and stress testing to find the best combination of processes.

It is also very important to choose one extension of PHP OPCode cache. Under linux 2.6 core, fcgi and xcache have good practical experience, while others have serious performance degradation after the concurrency number increases. If you really want to experience it, you would rather compile several more versions of PHP than collect various extensions for one version of PHP to adapt to various environments, which will push you into a dilemma.
