php安装vld扩展

1、查看本地是否已经安装了vld扩展，如果没有任何输出，那就准备安装吧！

[root@taiwu ~]# /home/work/lib/php5.6.7/bin/php -m | grep vld

2、去官方网站下载vld（http://pecl.php.net/package/vld）, 找到最新版本，右键复制地址链接就能得到下载地址，通过浏览器直接下载也行。

我是通过wget命令在centos的命令行执行，进行下载（wget http://pecl.php.net/get/vld-0.14.0.tgz）

[root@liuchao taiwu]# wget http://pecl.php.net/get/vld-0.14.0.tgz

-rw-r--r--. 1 root root 20506 12月 19 2016 vld-0.14.0.tgz

3、执行安装vld扩展的步骤

解压下载的tar包，进入解压后的目录
```
tar zxvf vld-0.14.0.tgz    
cd vld-0.14.0 
```
执行
```
/home/work/lib/php5.6.7/bin/phpize
```

知道php-config路径（用命令locate php-config可以得到），然后执行

./configure --with-php-config=/home/work/lib/php5.6.7/bin/php-config --enable-vld

然后执行
```
make && make install
```

[root@liuchao taiwu]# ls

----------------------------------------------------------------------
Libraries have been installed in:
   /root/taiwu/vld-0.14.0/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:     /home/work/lib/php5.6.7/lib/php/extensions/no-debug-non-zts-20131226/
[root@liuchao vld-0.14.0]#

最终可以看到，扩展安装到了如下目录中（ /home/work/lib/php5.6.7/lib/php/extensions/no-debug-non-zts-20131226/）

4、安装好了vld扩展以后，进行配置php.ini

*通过locate命令轻松找到php.ini的路径

[root@liuchao vld-0.14.0]# locate php.ini
/home/work/lib/php5.6.7/etc/php.ini
[root@liuchao vld-0.14.0]# vi /home/work/lib/php5.6.7/etc/php.ini

配置文件中已经有了扩展的路径配置

加上扩展配置（extension=vld.so）

5、对应通过命令行执行的php，已经可以用vld了

创建一个php脚本

[root@liuchao vld-0.14.0]# echo '<?php echo 123;' > 1.php

执行脚本

[root@liuchao vld-0.14.0]# /home/work/lib/php5.6.7/bin/php -dvld.active=1 1.php
