转自：https://blog.csdn.net/qq_16885135/article/details/78130281

1.从 https://pecl.php.net/package/imagick 下载源码包，并解压

2.phpize

提示：

#The program 'phpize' is currently not installed. You can install it by typing:
sudo apt install php7.0-dev

使用 sudo apt install php7.0-dev 安装 php7.0-dev 后

phpize

Configuring for:
PHP Api Version:         20151012
Zend Module Api No:      20151012
Zend Extension Api No:   320151012

3. 进入解压后的目录，执行 ./configure

报错1：

checking for pkg-config... no
pkg-config not found
configure: error: Please reinstall the pkg-config distribution

使用 sudo apt-get install pkg-config 安装 pkg-config 后成功解决报错1.

重新执行 ./configure

报错2：

checking ImageMagick MagickWand API configuration program... checking Testing /usr/local/bin/MagickWand-config... Doesn't exist
checking Testing /usr/bin/MagickWand-config... Doesn't exist
checking Testing /usr/sbin/bin/MagickWand-config... Doesn't exist
checking Testing /opt/bin/MagickWand-config... Doesn't exist

使用 sudo apt-get install libmagickwand-dev libmagickcore-dev 安装 libmagickwand-dev 和 libmagickcore-dev 成功解决报错2。

此后 ./configure 顺利执行完成。

4. sudo make && sudo make install 顺利安装完成

最后两行：

Installing shared extensions:     /usr/lib/php/20151012/
Installing header files:          /usr/include/php/20151012/

此时可以在 /usr/lib/php/20151012/ 目录下看到 imagick.so 文件。

cd /etc/php/7.0/mods-available/

sudo vim imagick.ini
填入：'extension=imagick.so' 并保存

cd /etc/php/7.0/fpm/conf.d
sudo ln -s /etc/php/7.0/mods-available/imagick.ini 20-imagick.ini

重启 php-fpm
