PHP compilation and installation Detailed explanation of each PHP compilation parameter configuration

This article introduces the compilation and installation of PHP. The detailed configuration of each compilation parameter of PHP is shared with everyone now, and it can also be used as a reference for friends who need help.

• Basic steps for php compilation and installation

//首先要下载一个php的安装包,例如:php-5.6.25.tar.gz,tar zxvf php-5.6.25.tar.gz // 解压php安装包,得到一个php-5.6.25的文件夹cd php-5.6.25 ./configure //对php的安装进行配置,后面要加配置选项# make && make install //编译安装完成之后,需要从解压后的文件夹中把php.ini-development //或是 php.ini-production 重命名成php.ini 复制到php安装文件中的相应位置,//可在phpinfo中查看 相应位置.// 把/usr/local/php/etc/php-fpm.conf.default 复制到当前文件夹下,保存未php-fpm.conf

The above are the basic steps for php compilation and installation Process, the following describes the configuration parameters of php in detail.

--prefix=/usr/local/php //指定 php 安装目录 --with-apxs2=/usr/local/apache/bin/apxs //整合apache， //apxs功能是使用mod_so中的LoadModule指令， //加载指定模块到 apache，要求 apache 要打开SO模块--with-config-file-path=/usr/local/php/etc //指定php.ini位置--with-MySQL=/usr/local/mysql //mysql安装目录，对mysql的支持--with-mysqli=/usr/local/mysql/bin/mysql_config //mysqli扩展技术不仅可以调用MySQL的存储过程、处理MySQL事务， //而且还可以使访问数据库工作变得更加稳定。--enable-safe-mode //打开安全模式 --enable-ftp //打开ftp的支持 --enable-zip //打开对zip的支持 --with-bz2 //打开对bz2文件的支持 --with-jpeg-dir //打开对jpeg图片的支持 --with-png-dir //打开对png图片的支持 --with-freetype-dir //打开对freetype字体库的支持 --without-iconv //关闭iconv函数，各种字符集间的转换 --with-libXML-dir //打开libxml2库的支持 --with-XMLrpc //打开xml-rpc的c语言 --with-zlib-dir //打开zlib库的支持 --with-gd //打开gd库的支持 --enable-gd-native-ttf //支持TrueType字符串函数库 --with-curl //打开curl浏览工具的支持 --with-curlwrappers //运用curl工具打开url流 --with-ttf //打开freetype1.*的支持，可以不加了 --with-xsl //打开XSLT 文件支持，扩展了libXML2库 ，需要libxslt软件 --with-gettext //打开gnu 的gettext 支持，编码库用到 --with-pear //打开pear命令的支持，PHP扩展用的 --enable-calendar //打开日历扩展功能 --enable-mbstring //多字节，字符串的支持 --enable-bcmath //打开图片大小调整,用到zabbix监控的时候用到了这个模块--enable-sockets //打开 sockets 支持--enable-exif //图片的元数据支持 --enable-magic-quotes //魔术引用的支持 --disable-rpath //关闭额外的运行库文件 --disable-debug //关闭调试模式 --with-mime-magic=/usr/share/file/magic.mime //魔术头文件位置

• CGI Parameters only used for installation:

--enable-fpm //打上PHP-fpm 补丁后才有这个参数，CGI方式安装的启动程序--enable-fastCGI //支持fastcgi方式启动PHP--enable-force-CGI-redirect //重定向方式启动PHP--with-ncurses //支持ncurses 屏幕绘制以及基于文本终端的图形互动功能的动态库--enable-pcntl //freeTDS需要用到的，可能是链接mssql 才用到--with-mcrypt //mcrypt算法的扩展--with-mhash //mhash算法的扩展//以上函数库需要安装--with-gmp //应该是支持一种规范--enable-inline-optimization //优化线程--with-openssl //openssl的支持，加密传输时用到的--enable-dbase //建立DBA 作为共享模块--with-pcre-dir=/usr/local/bin/pcre-config //perl的正则库案安装位置--disable-dmalloc --with-gdbm //dba的gdbm支持--enable-sigchild --enable-sysvsem --enable-sysvshm --enable-zend-multibyte //支持zend的多字节--enable-mbregex --enable-wddx --enable-shmop --enable-soap

• Notes

• specified After setting --with-apxs2=/usr/local/apache/bin/apxs, do not activate --enable-fpm and --enable-fastCGI. apxs loads PHP in php module mode.

• Mysql After compiling the Mysql development library, you do not need to specify the path to mysql.

• PHP compilation has basic dependencies. To compile PHP, you first need to install the XML extension, because the php5 core has XML support turned on by default. Other basic libraries require the following: GD -> ; zlib, Png, Jpg, if you need to support others, you still need to compile the extension library according to the actual situation. The ttf library needs the support of the freetype library.

• --enable-magic-quotes is an extremely not recommended parameter. Of course, if you need PHP to do the underlying work for you, in fact it is not very thorough. Solve the problem.

• --with-openssl, requires openssl library. 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 the PHP platform. PDO has been proven to be a simple, high-concurrency, and easy-to-create and recycle standard interface. However, PDO also experienced memory overflow problems before 5.3. After 5.3, when reading Oracle's LOB resources, if the memory is not restricted, memory overflow will still occur.
  If it is product mode, it is not recommended to use pear, shmop, ftp, etc. What they have to do is to use C/C++, Java, or even other scripting languages. There are good and fast options. No need to Limited to using PHP to implement. Unfamiliar class libraries and libraries that are not commonly used are not recommended. Magic-quote, session.auto_start, PHP server information, PHP error information, etc. should be closed as soon as possible after compilation is completed to avoid exposing server information.

  The Web Server mode corresponding to PHP only requires one of Module, fastcgi, and fpm. The server is not your experimental field. Fastcgi can choose Nginx and lighttpd. In fact, Nginx also uses lighttpd's spwan-fcgi for fcgi process management. fpm uses PHP itself to manage multiple processes, somewhat similar to a back-end proxy. Regardless of the mode, when releasing a product server, process and thread tuning should be done, and enough stress testing should be done to find the best combination of process numbers.

  Choose a PHP OPCode cache extension. This is also very important. Under Linux 2.6 core and fcgi, xcache has good practical experience. Others will have serious performance degradation after the number of concurrency increases.

  If you really want to experience it, you would rather compile several more PHP versions than collect various extensions for one version of PHP to adapt to various environments. This will put yourself in a dilemma.

• Extensions that need to be installed separately

• gd library.

• ming extension.

• Extensions for mhash and mcrypt.

Regarding the detailed options, in addition to the above installation introduction, other options can also be added during compilation.
