当php已经编译好在运行，又不想停机重新编译时可用此方法增加扩展。
增加自已写的库也可用此方法，参考HonestQiao 的记录

php之前的编译环境，
增加运行phpmsnclass需mhas和pcntl库为例
1.先下载类库
cd /home/c1g/src/
wget http://blog.s135.com/soft/linux/nginx_php/mcrypt/libmcrypt-2.5.8.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/mhash/mhash-0.9.9.9.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/mcrypt/mcrypt-2.6.8.tar.gz
2.编译安装类库
- tar zxvf libmcrypt-2.5.8.tar.gz
- cd libmcrypt-2.5.8/
- ./configure
- make
- make install
- /sbin/ldconfig
- cd libltdl/
- ./configure --enable-ltdl-install
- make
- make install
- cd ../../
- tar zxvf mhash-0.9.9.9.tar.gz
- cd mhash-0.9.9.9/
- ./configure
- make
- make install
- cd ../
- ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
- ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
- ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
- ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
- ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
- ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
- ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
- ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
- ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
- tar zxvf mcrypt-2.6.8.tar.gz
- cd mcrypt-2.6.8/
- /sbin/ldconfig
- ./configure
- make
- make install
- cd ../
3.开始编译安装mhash扩展
进入php原始编译目录
- cd /home/c1g/src/php-5.2.6/ext/mhash
- /opt/php/bin/phpize
- #会有以下信息生成，并产生编译文件
- #Configuring for:
- #PHP Api Version: 20041225
- #Zend Module Api No: 20060613
- #Zend Extension Api No: 220060519
- ./configure --with-php-config=/opt/php/bin/php-config
- make
- make install
生成的mhash.so会存下以下目录
Installing shared extensions: /opt/php/lib/php/extensions/no-debug-non-zts-20060613/
4.安装pcntl
- cd ../pcntl
- /opt/php/bin/phpize
- ./configure --with-php-config=/opt/php/bin/php-config
- make
- make install
生成的pcntl.so会存下以下目录
Installing shared extensions: /opt/php/lib/php/extensions/no-debug-non-zts-20060613/
5.编辑php.ini，指定好扩展的目录和需加载的库
- extension_dir = "/opt/php/lib/php/extensions/no-debug-non-zts-20060613/"
- extension="mhash.so"
- extension="pcntl.so"
6.重新reload一下php
7.检查下是否已生效
/opt/php/bin/php -m
