为什么不会启动php5-fpm?

我刚安装了PHP的FPM 5.6.8,但它不会启动 – start php5-fpm给我一个Job failed to start消息。 我发现有几个人有西摩拉问题,但是没有一个答案似乎对我有用。

我尝试的一个解决scheme是使用/etc/init/php5-fpm.conf的命令,该命令是/usr/sbin/php5-fpm --nodaemonize --fpm-config /etc/php5/fpm/php-fpm.conf – 这返回-bash: /usr/sbin/php5-fpm: No such file or directory – 我想这是一个很大的线索,可能是错误的。 尝试运行在前台模式php5-fpm -y /etc/php5/fpm/php-fpm.conf告诉我The program 'php5-fpm' is currently not installed. You can install it by typing: sudo apt-get install php5-fpm The program 'php5-fpm' is currently not installed. You can install it by typing: sudo apt-get install php5-fpm 。 这样做返回以下内容:

 Reading package lists... Done Building dependency tree Reading state information... Done php5-fpm is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies. webmin : Depends: libnet-ssleay-perl but it is not going to be installed Depends: libauthen-pam-perl but it is not going to be installed Depends: libio-pty-perl but it is not going to be installed Depends: apt-show-versions but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). 

任何人都可以弄清楚这是怎么回事? 顺便说一句,我正在使用Ubuntu Server 14.04.2。
