linux下安装 gd扩展和 ftp扩展

1、进入php安装源码包，找到ext下的ftp，进入

cd /usr/local/mysql/support-files/php-7.0.12/ext/ftp

2、/usr/local/php/bin/phpize

3、./configure --with-php-config=/usr/local/php/bin/php-config --enable-ftp

4、make && make install

5、vim /etc/php.ini  添加 : extension=ftp.so

6、重启apache,/usr/local/apache/bin/apachectl restart

7、查看是否安装成功:/usr/local/php/bin/php -m

找到ftp说明成功

gd拓展

1:安装gd的依赖包 

  yum -y install gd gd2 gd-devel gd2-devel zlib freetype

 安装jpeg:

  wget  http://www.ijg.org/files/jpegsrc.v9b.tar.gz

  tar -xvf jpegsrc.v9b.tar.gz

 ./configure --prefix=/usr/local/jpeg --enable-shared --enable-static

make && make install

2:进入php扩展目录编译扩展

  cd /usr/local/php/include/php/ext/gd

/usr/local/php/bin/phpize

 编译GD扩展：

  ./configure --with-php-config=/usr/local/php/bin/php-config -with-png-dir --with-freetype-dir --with-jpeg-dir=/usr/local/jpeg -with-zlib-dir --with-gd 

 make 

 make install

这是会提示：Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212（这个路径就是扩展的路径）

cd   /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212

就能看到扩展了：gd.so 扩展已经编译成功了
