php编译openssl模块的步骤

最近我们打算在php框架中使用composer来管理依赖关系,但是在执行composer的安装命令时(如下),发现系统提示没有安装openssl扩展类库。

安装composer命令:

sudocurl -s https://getcomposer.org/installer | sudo php

异常如下:

Some settings onyour machine make Composer unable to work properly.

Make sure thatyou fix the issues listed below and run this script again:

The opensslextension is missing, which means that secure HTTPS transfers areimpossible.

If possible youshould enable it or recompile php with --with-openssl



看到这个异常,应该是我的php在编译的过程中没有增加-with-openssl选项造成的。但是在网上搜索相关问题时,发现我们不需要重新编译php环境,可以借助phpize来只编译openssl.so文件,并把该文件添加到php.ini文件中的。

1.环境

1)操作系统:

Linuxubuntu 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014x86_64 x86_64 x86_64 GNU/Linux

2)php源码目录:

/home/wuguowei/software/php-5.5.14_source

3)php编译后的目录:

/home/wuguowei/software/php5.5

2.步骤

#从源码目录拷贝openssl目录到编译后的目录文件中

sudocp -r /home/wuguowei/software/php-5.5.14_source/ext/openssl /home/wuguowei/software/php5.5/include/php/ext

#进入php编译后的目标文件中

cd/home/wuguowei/software/php5.5/include/php/ext

#依次执行如下代码

/home/wuguowei/software/php5.5/bin/phpize

./configure--with-openssl?with-php-config=/home/wuguowei/software/php5.5/bin/php-config

make&& make install

#找到php.ini文件(通常在/etc/php.in)中的“DynamicExtensions”的内容,在末尾添加上“extension= openssl.so”

#重启php服务器即可

#查看编译后的openssl的方法

php-i |grep 'openssl'

正确的结果如下:

root@ubuntu:/home/wuguowei/software/composer#php -i |grep openssl

openssl

OLDPWD=> /home/wuguowei/software/php5.5/include/php/ext/openssl

_SERVER["OLDPWD"]=> /home/wuguowei/software/php5.5/include/php/ext/openssl



#查看php命令在哪儿的命令

whereis php

which php
