linux下编译php追加enable的方法

如果我们运行php时发现缺少某个库，在windows环境下很简单，找到.dll 对应的库文件，然后拷贝到 extension 目录下，然后在php.ini 里 去掉 前面的分号或者 追加一行 extension = XXXX.dll 即可。

linux环境下，可不是像windows环境下那么的简单。

下面我们已 sysvmsg 这个库文件的安装为例 来详细说明php的编译方法

收件进入php的原始文件

比如我是下载在这个路径下：

[root@localhost php-5.2.17]# cd /root/lnmp0.9-full/php-5.2.17

然后进入 ext 目录

/root/lnmp0.9-full/php-5.2.17/ext

接下来要进入我们需要增加的扩展的包 比如 这里是 sysvmsg

[root@localhost ext]# cd sysvmsg/

接下来我们需要在 sysvmsg 这个目录下创建 configure文件

[root@localhost sysvmsg]# /usr/local/php/bin/phpize  （这里是我们php默认的已经安装的地址）

执行之后会提示以下信息：

[root@localhost sysvmsg]# /usr/local/php/bin/phpize 
Configuring for: 
PHP Api Version:         20041225 
Zend Module Api No:      20060613 
Zend Extension Api No:   220060519

此时我们可以看到 目录下会多出来很多文件

---------------------------------------------------------------------- 
Libraries have been installed in: 
   /root/lnmp0.9-full/php-5.2.17/ext/sysvmsg/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'.

[root@localhost sysvmsg]# make install 
Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non                                                                                        -zts-20060613/

到这里我们就是安装完成了，会在extentsion目录下创建需要用到得.so 库文件

[root@localhost no-debug-non-zts-20060613]# ll 
total 504 
-rwxr-xr-x 1 root root 340289 Feb 22 19:02 memcache.so

-rw-r--r-- 1 root root 45469 Feb 25 17:26 php.ini

然后我们需要修改php.ini 新增 .so 库文件

extension = "sysvmsg.so"

用wq 保存php.ini.

最后别忘了重新启动php

[root@localhost etc]# ps -ef | grep php 
root     11702     1  0 17:20 ?        00:00:00 /usr/local/php/bin/php-cgi --fpm --fpm-config /usr/local/php/etc/php-fpm.conf

[root@localhost etc]# /usr/local/php/sbin/php-fpm start

好了，这样我们就完成了一个新的模块的安装。
