制定扩展文件目录：
extension_dir = /opt/php/lib/php/extensions/no-debug-non-zts-20100525
可以通过phpinfo来查找目录名（搜索extension_dir字符串）：
设置环境变量：
vim /etc/profile#内容类似于PATH=/opt/php/bin:/opt/php/sbin:$PATHexport PATH#保存关闭后source /etc/profile
安装ImageMagick与Imagick
下载ImageMagick
下载Imagick
先安装ImageMagick，再安装Imagick。
ImageMagick安装：
./configure --prefix=/opt/ImageMagickmakemake install
Imagick安装：
export PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig/opt/php/bin/phpize./configure --with-imagick=/opt/ImageMagick --with-php-config=/opt/php/bin/php-configmakemake install
imagick安装完成后，将自动把imagick.so文件复制到php的extension目录下，我的extension目录为：
/opt/php/lib/php/extensions/no-debug-non-zts-20100525/
配置Imagick：
在php.ini中加入：extension="imagick.so"。
如果SELinux打开了，那么需要运行下面这个命令：
restorecon /opt/php/lib/php/extensions/no-debug-non-zts-20100525/imagick.so
eAccelerator安装
下载eAccelerator
/opt/php/bin/phpize./configure --enable-eaccelerator=shared --with-eaccelerator-info --with-eaccelerator-disassembler --with-php-config=/opt/php/bin/php-configmakemake install
配置eAccelerator
如果开启了Selinux，请运行:
restorecon /opt/php/lib/php/extensions/no-debug-non-zts-20100525/eaccelerator.so
创建缓存目录：
mkdir /var/cache/eacceleratorchmod 777 /var/cache/eaccelerator
在php.ini中加入：
[eaccelerator]extension = "eaccelerator.so"eaccelerator.shm_size="16"eaccelerator.cache_dir="/var/cache/eaccelerator"eaccelerator.enable="1"eaccelerator.optimizer="1"eaccelerator.check_mtime="1"eaccelerator.debug="0"eaccelerator.filter=""eaccelerator.shm_max="0"eaccelerator.shm_ttl="3600"eaccelerator.shm_prune_period="3600"eaccelerator.shm_only="0"eaccelerator.compress="1"eaccelerator.compress_level="9"
配置eAccelerator的web管理页面：
1.编译安装时，需要加上--with-eaccelerator-info参数
2.将安装目录下的control.php文件复制到web目录下，使用浏览器访问。
默认control.php集成了http验证，用户名密码可以在文件中找到，也可以关闭Http验证，这一切，使用编辑器打开control.php文件就懂了。
