Linux 环境下编译安装 PHP 扩展

线上的生产环境通常为 LNMP,当因为业务需求需要用到某些扩展包,而那个扩展包需要相应版本的 PHP 扩展的时候,就需要安装对应的 PHP 扩展。

编译安装扩展的方式都大同小异,这里就以安装 Yaf 框架的扩展为例,来演示如何编译安装 PHP 的扩展。

1. 进入 PHP 扩展的官网

2. 找到右上角的搜索框,输入 Yaf,下载最新版本的压缩包到服务器的指定目录。

[root@localhost src]# wget http://pecl.php.net/get/yaf-3.0.7.tgz
--2018-12-17 00:06:28--  http://pecl.php.net/get/yaf-3.0.7.tgz

[root@localhost src]# 
3. 解压缩软件包。
[root@localhost src]# tar -zxvf yaf-3.0.7.tgz
4. 配置、编译、安装
[root@localhost src]# cd yaf-3.0.7/
[root@localhost yaf-3.0.7]# /usr/local/php/bin/phpize

[root@localhost yaf-3.0.7]# make && make install


编译和安装的过程省略了...

/bin/sh /usr/local/src/yaf-3.0.7/libtool --mode=install cp ./yaf.la /usr/local/src/yaf-3.0.7/modules
cp ./.libs/yaf.so /usr/local/src/yaf-3.0.7/modules/yaf.so
cp ./.libs/yaf.lai /usr/local/src/yaf-3.0.7/modules/yaf.la
PATH="$PATH:/sbin" ldconfig -n /usr/local/src/yaf-3.0.7/modules
----------------------------------------------------------------------
Libraries have been installed in:
 /usr/local/src/yaf-3.0.7/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
 - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
   during execution
 - add LIBDIR to the `LD_RUN_PATH' environment variable
   during linking
 - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
 - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/
[root@localhost yaf-3.0.7]# 
5. 修改 PHP 配置文件,验证配置

由上面可知,扩展已经被安装到了 /usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/ 这个目录里面,接下来需要在 PHP 的配置文件中添加 Yaf 这个扩展。

vim /etc/php.ini
846 
847 ;;;;;;;;;;;;;;;;;;;;;;
848 ; Dynamic Extensions ;
849 ;;;;;;;;;;;;;;;;;;;;;;
850 
851 ; If you wish to have an extension loaded automatically, use the following
852 ; syntax:
853 ;
854 ;   extension=modulename.extension
855 ;
856 ; For example, on Windows:
857 ;
858 ;   extension=msql.dll
859 ;
860 ; ... or under UNIX:
861 ;
862 ;   extension=msql.so
863 ;
864 ; ... or with a path:
865 ;
866 ;   extension=/path/to/extension/msql.so
867 ;
868 ; If you only provide the name of the extension, PHP will look for it in its
869 ; default extension directory.
870 ;
871 ; Windows Extensions
872 ; Note that ODBC support is built in, so no dll is needed for it.
873 ; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5+)
874 ; extension folders as well as the separate PECL DLL download (PHP 5+).
875 ; Be sure to appropriately set the extension_dir directive.
876 ;
877 ;extension=php_bz2.dll
878 ;extension=php_curl.dll
879 ;extension=php_fileinfo.dll
880 ;extension=php_ftp.dll

在这块区域附近加入一行代码:

extension=yaf.so

关闭配置文件,重启服务。

[root@localhost no-debug-non-zts-20151012]# service php-fpm restart 
Gracefully shutting down php-fpm . done
Starting php-fpm  done

在浏览器中查看 phpinfo,确认扩展是否安装成功。

至此,PHP的扩展安装结束。
