[乐意黎原创]PHP抛PHP Startup:Unable to load dynamic library "bcmath,Libmcrypt,mhash,mcrypt"等警告及...

如下，Centos里启动 php-fpm 时，控制台总在抛若干警告。

由于折腾 Centos主机不是很溜，安装php时参考了别人的配置，编译php时没有开启若干扩展（很大的一个坑啊）.

在实际使用中抛错了，再想添加扩展，然而不想卸载后再重装，这下就需要用到phpize来帮忙了。

比如增加bcmath扩展的支持，这是一个支持大整数计算的扩展。

由于windows系统是自带而且内置，linux“本类函数仅在 PHP 编译时配置了 --enable-bcmath 时可用”（引号内是手册中的话）

PHP 版本： php-7.2.11，

PHP源文件路径： /usr/local/src/php-7.2.11

PHP的安装后路径： /usr/local/php/
php.ini 文件路径： /etc/php.ini

对应的模块.ini 文件路径： /etc/php.d/

php-config 路径： /usr/local/php/bin/php-config

扩展模块安装路径： /usr/local/php/lib/php/extensions/no-debug-zts-20170718

解决方法：
首先，确保抛警告的模块都已经安装。

1. 进入源文件路径目录: cd /usr/local/src/php-7.2.11/ext

2. 进入bcmath目录(安装其它模块，换成其它模块名称即可): cd bcmath

3. 然后执行输入: /usr/local/php/bin/phpize

4. 然后再执行: ./configure --with-php-config=/usr/local/php/bin/php-config

5. 执行命令: make && make install

注:(基于安装bcmatch, 以上命令均在 /usr/local/src/php-7.2.11/ext/bcmath 下执行)

控制台操作步骤:

[root@aerchi ext]# cd /usr/local/src/php-7.2.11/ext/bcmath[root@aerchi bcmath]# lsbcmath.c config.m4 CREDITSpackage.xml testsbcmath.loconfig.w32libbcmathphp_bcmath.h[root@aerchi bcmath]# /usr/local/php/bin/phpizeConfiguring for:PHP Api Version: 20170718Zend Module Api No:20170718Zend Extension Api No: 320170718[root@aerchi bcmath]# ./configure --with-php-config=/usr/local/php/bin/php-config......config.status: creating config.h[root@aerchi bcmath]# make && make install......----------------------------------------------------------------------Libraries have been installed in: /usr/local/src/php-7.2.11/ext/bcmath/modulesSee any operating system documentation about shared libraries formore 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-20170718/

以上，提示安装完成，然后进入 /usr/local/php/lib/php/extensions/no-debug-zts-20170718/ 路径下查看:

如下，模块安装完成，下面，来检查一下。

(注：针对上面检查的问题，极有可能是php.ini 配置文件里没有启用扩展模块路径，见其次)

进入 php.ini 查看，抛错的正是启用的扩展模块.

其次，在php.ini配置文件中，修改 extension_dir的路径(大概 730 行左右)及启用对应模块等。

如笔者的php 扩展模块路径为: /usr/local/php/lib/php/extensions/no-debug-zts-20170718/
原始：

修改后:

最后，别忘记了重启php-fpm, 并重启nginx 或者apache，reload不行，一定要重启.

ps -ef|grep nginx # 查看nginx 进程#php-fpmpkill -9 php-fpmservice php-fpm stopservice php-fpm start#nginx/usr/local/nginx/sbin/nginx -s stop/usr/local/nginx/sbin/nginx -s reload/usr/local/nginx/sbin/nginx //启动#apacheapachectl stopapachectl start

升级 php 7.2 后，使用微信提供的加解密代码时，提示 call to undefined function mcrypt_module_open() ；大脑疯狂运转1秒钟后，得出结论：php 7.2的扩展有变动；查阅相关资料知晓，mcrypt 扩展从 php 7.1.0 开始废弃；自 php 7.2.0 起，会移到 pecl。还好，安装过程不复杂。
环境：centos 7

yum 安装依赖包：

yum install libmcrypt libmcrypt-devel mcrypt mhash

pecl

apt-get install php-pecl

安装Libmcrypt

# cd /usr/local/src# wget  https://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download# tar -zxvf libmcrypt-2.5.8.tar.gz # cd libmcrypt-2.5.8 # /usr/local/php5/bin/phpize #动态编译php模块，使其可以使用configure编译。 # ./configure --with-php-config=/usr/local/php/bin/php-config # make && make install# libmcript默认安装在/usr/local

安装mhash

Mhash是基于离散数学原理的不可逆向的php加密方式扩展库，其在默认情况下不开启。mhash的可以用于创建校验数值，消息摘要，消息认证码，以及无需原文的关键信息保存（如密码）等。

# cd /usr/local/src# wget  https://sourceforge.net/projects/mhash/files/mhash/0.9.9.9/mhash-0.9.9.9.tar.gz/download# tar -zxvf mhash-0.9.9.9.tar.gz # cd mhash-0.9.9.9 # /usr/local/php5/bin/phpize  # ./configure --with-php-config=/usr/local/php/bin/php-config # make  &&  make install

安装mcrypt
Mcrypt 扩展库可以实现加密解密功能，就是既能将明文加密，也可以密文还原。PHP加密扩展库Mcrypt的算法和加密模式.

# cd /usr/local/src---------------------# wget https://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download # tar -zxvf mcrypt-2.6.8.tar.gz # cd mcrypt-2.6.8 或# wget http://pecl.php.net/get/mcrypt-1.0.1.tgz# tar xf mcrypt-1.0.1.tgz# cd mcrypt-1.0.1-------------------# /usr/local/php/bin/phpize  # ./configure --with-php-config=/usr/local/php/bin/php-config # make && make install

安装完毕,按照编译安装后的提示

注：比如，zip, phar, fileinfo 模块安装也是类似, 只需将 解决方法 (2) 里的模块路径分别换成 zip, phar, fileinfo，并执行3、4、5步即可。

其它方法:

1. 打开/usr/local/php/bin/php-config注释掉：extension_dir='/usr/local/php/lib/php/extensions/no-debug-zts-20170718/'解决的

网上的解决方法是打开/usr/local/php/bin/php-config
注释掉：extension_dir='/usr/local/php/lib/php/extensions/no-debug-zts-20170718/',
但是无效，最终解决方式删除 /etc/php.d 下的对应的 .ini 报错文件！！！

2. 将/etc/php.d/ 目录下的.ini文件全部重命名为.so文件, 或删除对应的 *.ini 文件

如：cp /etc/php.d/zip.ini /etc/php.d/zip.so

若有扩展被重复加载了，打开/etc/php.ini文件，注释扩展加载的地方即可

vi /etc/php.ini # 将redis、memcache、swoo加载的地方注释即可/etc/init.d/php-fpm restart

3. 其它：

PHP 目录结构:

1. build 和编译有关的目录。

2. ext 扩展库代码，例如 mysql、zlib、iconv 等我们熟悉的扩展库。其中/ext/standard/目录下是常用的标准函数集。

3. main 主目录包含主要的 PHP 宏和定义。

4. sapi 和各种服务器的接口调用，例如apache、IIS等，也包含一般的fastcgi、cgi等。

5. win32 和 Windows 下编译 PHP 有关的脚本。

6. Zend 文件夹核心的引擎，所有的 Zend API 定义与宏等。

7. scripts Linux 下的脚本目录。

8. tests 测试脚本目录

9. sapi 各类 Web 服务器的接口。

10.TSRM Zend 和 PHP 的 “线程安全资源管理器” (TSRM) 目录。

11.pear 这个目录就是“PHP 扩展与应用仓库”的目录。包含了PEAR 的核心文件。

其中几个重要的文件绝对值得你共时间去了解：

php-src/main/php.h, 位于PHP 主目录。这个文件包含了绝大部分 PHP 宏及 API 定义。

php-src/Zend/zend.h, 位于 Zend 主目录。这个文件包含了绝大部分 Zend 宏及 API定义。

php-src/Zend/zend_API.h, 也位于 Zend 主目录，包含了Zend API的定义
