Prohibit IP from accessing the site by multiple methods to share of linux php nginx apache

PHP prohibits access to an IP or IP segment

Without further ado, please look at the guest officer:

<?  
// Ban a IP
$banned_ip = array (
"127.0.0.1",
//"119.6.20.66",
"192.168.1.4"
);
if ( in_array( getenv("REMOTE_ADDR"), $banned_ip ) )
{
die (" your IP No access! ");
}
// Ban a IP Period of 
$ban_range_low=ip2long("119.6.20.65");
$ban_range_up=ip2long("119.6.20.67");
$ip=ip2long($_SERVER["REMOTE_ADDR"]);
if ($ip>$ban_range_low && $ip<$ban_range_up)
{
echo " your IP In prohibited IP Section, no access! ";
exit();
}
?> 

apache prohibits access using IP

Method 1: at the end of the httpd.conf file, add the following code

NameVirtualHost 221.*.*.*
<VirtualHost 221.*.*.*>
ServerName 221.*.*.*
<Location />
Order Allow,Deny
  　　　　Deny from all
</Location>
</VirtualHost>　　　　
<VirtualHost 221.*.*.*>
DocumentRoot "c:/web"
ServerName www.ofstack.com
</VirtualHost> 

Note: the blue part is the implementation to deny any access request directly through the IP of 221.*.*.*. The red part allows access through the domain name www.ofstack.com, and the home directory points to c:/web. (let's say the root of your site is c:/web.)

Linux blocks access to IP

# Block a single IP The command is 
iptables -I INPUT -s 123.45.6.7 -j DROP
# Seal the entire segment immediately from 123.0.0.1 to 123.255.255.254 The command 
iptables -I INPUT -s 123.0.0.0/8 -j DROP
# seal IP Section is from 123.45.0.1 to 123.45.255.254 The command 
iptables -I INPUT -s 124.45.0.0/16 -j DROP
# seal IP Section is from 123.45.6.1 to 123.45.6.254 The command is 
iptables -I INPUT -s 123.45.6.0/24 -j DROP
service iptables save 

Save in /etc/sysconfig/iptables if there is no iptables file will be created automatically

Nginx prohibits access to IP

First create the following configuration file and place it under nginx's conf directory, blocksip.conf:

deny 4.4.4.4 // this is IP to be banned by nginx

So let's save 1.
Add: include blocksip.conf; include blocksip.conf; Then restart nginx and it will take effect. When the blocked ip opens the site, it will prompt:

403 Forbidden

blocksip.conf: there are many other formats that can be configured to allow only IP access or IP segment access:

deny IP;
allow IP;
# block all ips
deny all;
# allow all ips
allow all;

The section is written like this: 192.168.1.0/24.
