security php,mysql,apache2
//
Just distributions of Debian.
//THIS TUTORIAL IS ONLY PART.
This tutorial is in addition to the tutorial “https://psgcenter.wordpress.com/2014/08/10/how-to-create-your-own-linux-server-hosting/” .
Let’s start.
1.
Type
nano /etc/apache2/apache2.conf
Added at the end like this:
ServerSignature Off ServerTokens Prod
After that add:
<Directory /var/www/html> Options -Indexes </Directory>
In the same file we add:
Options -FollowSymLinks
Let’s get to Mysql
Type
nano /etc/mysql/my.cnf
Added at the end
set-variable=local-infile=0
Now to PHP
Type
rm /etc/php5/sqlite3.ini
Dam to disable dangerous functions:
disable_functions =exec,passthru,shell_exec,system,proc_open,popen,c url_exec,curl_multi_exec,parse_ini_file,show_sourc e
Anti backdooring :
nano /etc/php5/security.ini
and add
cgi.force_redirect=On
Now go in / var / www and create an htaccess file and add this in it: (SQL injection and XSS is anti)
ServerSignature Off
Options -Indexes
