我想从 14.04 升级到 16.04 后安装 php7。以下是我得到的结果：
Setting up php7.0-fpm (7.0.8-0ubuntu0.16.04.2) ...
Job for php7.0-fpm.service failed because the control process exited with error code. See "systemctl status php7.0-fpm.service" and "journalctl -xe" for details.
invoke-rc.d: initscript php7.0-fpm, action "start" failed.
dpkg: error processing package php7.0-fpm (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
php7.0-fpm
E: Sub-process /usr/bin/dpkg returned an error code (1)
的输出sudo php-fpm7.0 -t为：
[07-Aug-2016 10:32:35] ERROR: failed to open configuration file '/etc/php/7.0/fpm/php-fpm.conf': No such file or directory (2)
[07-Aug-2016 10:32:35] ERROR: failed to load configuration file '/etc/php/7.0/fpm/php-fpm.conf'
[07-Aug-2016 10:32:35] ERROR: FPM initialization failed
答案1
对造成的不便表示歉意，
笔记：我在 14.04 中使用了 php7，然后将其删除并再次安装 php5。现在我想再次安装 php7。
解决此问题：
- 删除 php7.0-fpm：
sudo apt-get remove php7.0-fpm - 清除它：
sudo apt-get purge php7.0-fpm - 手动删除 /etc/php/7.0/fpm 目录：
sudo rm -rf /etc/php/7.0/fpm/ - 再次安装php7.0-fpm：
sudo apt-get install php7.0-fpm
