2. Store the file in the location which can be processed by any running Webserver. In this context of the article the file itself being processed by Apache Webserver, so just put it in the document root folder where by default it will be processed. Don’t forget to define it in a configuration file to inform Apache Webserver the location of the Adminer file so it can be processed. For an example, if the file itself has already been downloaded to the root home folder, in this context /root.

[root@localhost ~]# mkdir /usr/share/adminer && cp adminer-4.2.1.php /usr/share/adminer/index.php && cd /usr/share/adminer
[root@localhost adminer]# ls -al 
total 328
drwxr-xr-x. 2 apache apache 23 Agu 23 02:36 .
drwxr-xr-x. 79 root root 4096 Agu 23 02:36 ..
-rw-r--r--. 1 apache apache 330757 Agu 23 02:36 index.php
[root@dakfisik adminer]#

In this context of article, the file created will be named as ‘adminer.conf’ to make it easy to be recognized as the Adminer configuration file which is made to be processed by Apache Webserver. Below is the position of the file in the tree format :

root@hostname:/etc/httpd/conf.d# tree .
.
└── adminer.conf

0 directories, 1 files
root@hostname:/etc/httpd/conf.d#

4. Edit the file and insert the following content :

Alias /myadminer "/usr/share/adminer"
<Directory "/usr/share/adminer">
AllowOverride All
Options FollowSymlinks
Order deny,allow
Deny from all
Allow from all
Require all granted
</Directory>
