LAMP架构(9) PHP动态扩展模块安装

 
   PHP动态扩展模块安装 
  
    在php安装时，调用了httpd的apxs工具将所需的php模块整体打包成一个动态共享模块（.so文件）以供httpd调用。后续若要增加另外的php模块，要么重新安装php添加所需模块，要么直接将需要的模块编译成扩展模块（.so文件），在php.ini配置文件中指定一下就可以使用，相对重新安装php要便捷很多。

   在输出信息最后可以看到如下信息： 
  
   Libraries have been installed in: 
  
    /usr/local/src/phpredis-develop/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-zts-20131226/ 
  
    这是扩展模块的安装路径 
  
   [root@aliyun phpredis-develop]# echo $? 
  
   0 
  
   [root@aliyun phpredis-develop]# /usr/local/php/bin/php -i |grep extension_dir  
  
   查看扩展模块存放目录，此目录可以自定义，需在php.ini中指明路径 
  
   extension_dir => /usr/local/php/lib/php/extensions/no-debug-zts-20131226 =>  
   /usr/local/php/lib/php/extensions/no-debug-zts-20131226 
  
   sqlite3.extension_dir => no value => no value 
  
   [root@aliyun phpredis-develop]# ls /usr/local/php/lib/php/extensions/no-debug-zts-20131226 
  
   opcache.so  
   redis.so 
    查看编译好的扩展模块（.so文件） 
  
   [root@aliyun phpredis-develop]# echo "extension = redis.so" >> /usr/local/php/etc/php.ini  
  
   追加这行配置 extension 
     
   = 
     
   redis.so到php.ini配置文件的最后一行 
  
   查看安装的扩展模块redis是否加载成功：
