我们在Ubuntu上运行的Nginx服务器14.04.2 lts带有PHP5-fpm。
应用程序（OEMPRO）我正在尝试安装它：
PHP IMAP扩展程序被禁用。请启用它。
如何启用PHP IMAP？
我已经检查了我们的phpinfo，似乎IMAP在某种程度上存在，您可以在这里看到我们的phpinfo的屏幕截图。
，尽管我在mods-available/目录中找不到IMAP。
# ls /etc/php5/mods-available/
curl.ini gd.ini json.ini mcrypt.ini mysqli.ini mysql.ini opcache.ini pdo.ini pdo_mysql.ini readline.ini ssh2.ini
我需要在/etc/php5/fpm/php.ini中启用它？
更新
我尝试安装IMAP，但无法解决问题。OEMPRO仍然说IMAP已禁用。

我的 phpinfo保持不变，但我现在可以在 mods-available/中看到 imap.ini。
# ls /etc/php5/mods-available/
curl.ini gd.ini imap.ini json.ini mcrypt.ini mysqli.ini mysql.ini opcache.ini pdo.ini pdo_mysql.ini readline.ini ssh2.ini
我尝试仅从头开始安装PHP IMAP，起初它似乎不起作用，但是后来我也必须运行sudo php5enmod imap。
以下是您需要运行命令的顺序
sudo apt-get install php5-imap
sudo php5enmod imap
service php5-fpm restart
sudo service nginx restart
