Question

下面是我的系统中的代码，我找不到系统中的 php.ini 文件

mysystem@mysystem-dev1:/etc/php/7.2$ cd apache2/
mysystem@mysystem-dev1:/etc/php/7.2/apache2$ ls -ltr
total 4
drwxr-xr-x 2 root root 4096 Sep 13  2018 conf.d
mysystem@mysystem-dev1:/etc/php/7.2/apache2$ cd ..
mysystem@mysystem-dev1:/etc/php/7.2$ cd 7.1
bash: cd: 7.1: No such file or directory
mysystem@mysystem-dev1:/etc/php/7.2$ cd ../7.1
mysystem@mysystem-dev1:/etc/php/7.1$ ls -ltr

mysystem@mysystem-dev1:/etc/php/7.1/apache2$ 

我尝试使用 find 命令查找

mysystem@mysystem-dev1:/etc/php/7.1/apache2/conf.d$ sudo find / -name 'php.ini'
find: ‘/run/user/1000/gvfs’: Permission denied
mysystem@mysystem-dev1:/etc/php/7.1/apache2/conf.d$ sudo find / -iname 'php.ini'
find: ‘/run/user/1000/gvfs’: Permission denied
mysystem@mysystem-dev1:/etc/php/7.1/apache2/conf.d$ sudo find / -iname 'php.ini'
find: ‘/run/user/1000/gvfs’: Permission denied
mysystem@mysystem-dev1:/etc/php/7.1/apache2/conf.d$
