需要在php中使用gpg加密

function gpg() {

$keydata = file_get_contents('li7.asc');

$res = gnupg_init();

$info = gnupg_import($res, $keydata);

print_r($info);

}

gpg();

?>

functiongpg(){

$keydata=file_get_contents('li7.asc');

$res=gnupg_init();

$info=gnupg_import($res,$keydata);

print_r($info);

}

gpg();

?>

但是执行时报错

PHP Fatal error: Call to undefined function gnupg_init() in /home/wwwroot/default/imtools/debug/gpg.php on line 4

百度之后知道需要安装gnupg扩展[1]。

不认真搜索的代价

下载gnupg扩展及依赖

[root@HADOOP-215 libassuan-2.2.0]# history |grep "wget"

861 wget http://pecl.php.net/get/gnupg-1.3.6.tgz

[root@HADOOP-215libassuan-2.2.0]# history |grep "wget"

861wgethttp://pecl.php.net/get/gnupg-1.3.6.tgz

编译时提示

[root@HADOOP-215 gnupg-1.3.6]# ./configure --with-php-config=/usr/local/php/bin/php-config

....

checking for gnupg support... yes, shared

checking for gnupg files in default path... not found

查看gpgme,是安装了的

[root@HADOOP-215 debug]# rpm -qa |grep gpgme

gpgme-1.1.8-3.el6.x86_64

pygpgme-0.1-18.20090824bzr68.el6.x86_64

[root@HADOOP-215debug]# rpm -qa |grep gpgme

gpgme-1.1.8-3.el6.x86_64

pygpgme-0.1-18.20090824bzr68.el6.x86_64

没有想太多就按照提示直接去下载gpgme了,并且下载了最新的版本

wget ftp://ftp.gnupg.org/gcrypt/gpgme/gpgme-1.5.4.tar.bz2

wgetftp://ftp.gnupg.org/gcrypt/gpgme/gpgme-1.5.4.tar.bz2

编译时又有依赖关系

configure:

***

*** You need libgpg-error to build this program.

** This library is for example available at

*** ftp://ftp.gnupg.org/gcrypt/libgpg-error

*** (at least version 1.11 is required.)

***

configure:

***

*** You need libassuan to build this program.

*** This library is for example available at

*** ftp://ftp.gnupg.org/gcrypt/libassuan/

*** (at least version 2.0.2 (API 2) is required).

查看libgpg-error,确实是已安装,但是版本是1.7,gpgme-1.5.4要求1.11以上

[root@HADOOP-215 debug]# rpm -qa |grep error

libgpg-error-1.7-4.el6.x86_64

libgpg-error-devel-1.7-4.el6.x86_64

[root@HADOOP-215debug]# rpm -qa |grep error

libgpg-error-1.7-4.el6.x86_64

libgpg-error-devel-1.7-4.el6.x86_64

于是又按照提示下载了最新的libgpg-error和libassuan,编译成功。在php.ini中添加 extension=gnupg.so。但是浏览器访问phpinfo()不能显示页面,命令方式执行会报错,加载链接库有问题

[root@HADOOP-215 debug]# php gpg.php

php: relocation error: /usr/lib64/libgpgme.so.11: symbol gpg_err_set_errno, version GPG_ERROR_1.0 not defined in file libgpg-error.so.0 with link time reference

[root@HADOOP-215debug]# php gpg.php

php:relocationerror:/usr/lib64/libgpgme.so.11:symbolgpg_err_set_errno,versionGPG_ERROR_1.0notdefinedinfilelibgpg-error.so.0withlinktimereference

查看扩展需要加载的链接库和rpm安装的依赖文件路径,可以看到加载的还是rpm安装的依赖的路径

[root@HADOOP-215 debug]# ldd /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/gnupg.so

但是gnupg.so是用新版本的依赖库编译的,或许是因为这个原因php执行时报错吧。手动重新添加软连接到新版本的库

[root@HADOOP-215 libassuan-2.2.0]# history |grep "ln -s"

1072 ln -s /usr/local/php/bin/php /usr/bin/php

1147 ln -s /usr/local/lib/libgpgme.so.11.13.3 /usr/lib64/libgpgme.so

1182ln-s/usr/local/lib/libgpg-error.so.0.15.0/lib64/libgpg-error.so.0

之后可以正常执行

简单的步骤

真的很麻烦。回到开始,以关键词“Please reinstall the gpgme distribution

[2008-09-18 19:02 UTC] emmett dot keyser at sf dot tribalddb dot com

Hey, I think you need to install gpgme-devel. [2]

换台机器,安装gpgme-devel,之后可以直接成功编译gnupg扩展。

其他问题

一开始lnmp的php和yum安装的php共存,phpize是yum安装的,执行后编译gnupg扩展会默认安装到/usr/lib/php/module目录下,php.ini中设置时需要加路径。

相关知识

安装pecl扩展的方法,仅记录一种。下载扩展源码,用phpize准备编译环境[3]

$ phpize

$ ./configure

$ make

# make install

$phpize

$./configure

$make

# make install

共享库加载相关知识

这是摘抄《共享库PATH与ld.so.conf简析》

1. 往/lib和/usr/lib里面加东西,是不用修改/etc/ld.so.conf的,但是完了之后要调一下ldconfig,不然这个library会找不到

2. 想往上面两个目录以外加东西的时候,一定要修改/etc/ld.so.conf,然后再调用ldconfig,不然也会找不到 比如安装了一个到/usr/local/mysql,mysql有一大堆library在/usr/local/mysql/lib下面,这时就需要在/etc/ld.so.conf下面加一行/usr/local/mysql/lib,保存过后ldconfig一下,新的library才能在程序运行时被找到。

3. 如果想在这两个目录以外放lib,但是又不想在/etc/ld.so.conf中加东西(或者是没有权限加东西)。那也可以,就是export一个全局变量LD_LIBRARY_PATH,然后运行程序的时候就会去这个目录中找library。一般来讲这只是一种临时的解决方案,在没有权限或临时需要的时候使用。

4. ldconfig做的这些东西都与运行程序时有关,跟编译时一点关系都没有。编译的时候还是该加-L就得加,不要混淆了。

5. 总之,就是不管做了什么关于library的变动后,最好都ldconfig一下 [4]
