6、图像处理程序及imagick扩展模块安装
imagick扩展模块依赖于ImageMagick这个软件，因此需要下载两个软件，先安装ImageMagick这个软件，后装imagick扩展模块

**7****、配置PHP的扩展插件**
[root@localhost~]# cd /application/php/lib/
操作前备份
[root@localhostlib]# cp php.ini php.ini.bak.0929
[root@localhostlib]# ls
php php.ini php.ini.bak.0929
[root@localhost lib]#vi php.ini
; Thedirectory under which PHP opens the script using /~username used only
; ifnonempty.
user_dir =
; Directoryin which the loadable extensions (modules) reside.
;extension_dir= “./“
修改目录路径
extension_dir =”/application/php-5.3.27/lib/php/extensions/no-debug-non-zts-20090626/“
; Onwindows:
;extension_dir = “ext”
然后到文件内容的结尾增加如下配置
;php cacheconfig start
extension =memcache.so
extension = pdo_mysql.so
extension = imagick.so
;php cacheconfig end by root 2016-09-29
注意，PHP配置文件中注释是用;而不是#号
配置缓存插件eaccelerator
创建临时缓存目录
[root@localhostlib]# mkdir -p /tmp/eaccelerator
[root@localhostlib]# chown -R nginx.nginx /tmp/eaccelerator/
** 生产环境当中可以将此文件放在内存文件系统（tmpfs）中存储，提高并发时的速度，也可以存放在固态硬盘中**
[root@localhostlib]# cat /application/php/lib/php.iniEOF
[eaccelerator]
extension=eaccelerator.so
eaccelerator.shm_size=”64”
eaccelerator.cache_dir=”/tmp/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”
EOF
检查配置
[root@localhostlib]# tail -25 /application/php/lib/php.ini
; LocalVariables:
;tab-width: 4
; End:
;php cacheconfig start
extension =memcache.so
extension = pdo_mysql.so
extension = imagick.so
;php cacheconfig end by root 2016-09-29
[eaccelerator]
extension=eaccelerator.so
eaccelerator.shm_size=”64”
eaccelerator.cache_dir=”/tmp/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”
**8、测试缓存加速**
