剛開始用LINUX沒什麼經驗，CentOS 6.5自帶PHP5，當時不會刪就留著了，然後安裝了PHP7. 現在查看php -v結果顯示的是PHP 5.6. 怎麼讓系統預設使用PHP7呢？

剛剛把PHP全刪了“yum remove php*”，然後用YUM安裝了PHP7，現在php -v顯示是PHP 7了。

但是運行php-fpm的時候提示找不到檔案。我又用yum --enablerepo=remi install php php-fpm 安裝了一下php-fpm，執行後提示：

yum install php php-fpm php-mysql

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

運行php-fpm依然提示「-bash: /usr/sbin/php-fpm: No such file or directory」

再試這個安裝：
yum install php70-php-fpm.x86_64

該怎麼解決呢？

安裝完php-fpm後，最後提示
