sudo vi \/etc\/apache2\/apache2.conf
OR
Sudo vi \/etc\/httpd\/conf\/httpd.conf<\/pre>\n\n\n\nAdd the following statements in Directory, Files or Location blocks to allow\/block access, as per your requirement.<\/p>\n\n\n\n
Here is an example to allow access from only one IP address to root directory of your site \/var\/www\/html<\/p>\n\n\n\n
<Directory \"\/var\/www\/html\">
Require ip 12.34.56.78
<\/Directory><\/pre>\n\n\n\nHere is the command using Allow statement.<\/p>\n\n\n\n
<Directory \"\/var\/www\/html\">
Deny All
Allow 12.34.56.78
<\/Directory><\/pre>\n\n\n\nHere is the command to allow access to all URLs in \/product subfolder.<\/p>\n\n\n\n
<Location \"\/product\">
Require ip 12.34.56.78
<\/Location><\/pre>\n\n\n\nIf you need to provide access from multiple IP addresses, mention separate Require statements for each IP address.<\/p>\n\n\n\n
<Directory \"\/var\/www\/html\">
Require ip 12.34.56.78
Require ip 23.34.45.56
<\/Directory><\/pre>\n\n\n\nIf you need to allow access from a group of IP addresses, then you can also use a CIDR subnet mask to specify the range. Here is an example to allow access from 10.0.0.1 to 10.0.255.255.<\/p>\n\n\n\n
<Directory \"\/var\/www\/html\">
Require ip 10.0.0.0\/16
<\/Directory><\/pre>\n\n\n\nSometimes you may need to allow access from all IPs except one or more IP addresses. In such cases, use Require All statement to give access to all, followed by ‘Require not’ statements for IP addresses you want to block. Here is an example to allow access from all IP addresses but block IPs 12.23.34.45 and 20.0.0.0-20.0.255.255.<\/p>\n\n\n\n
<Directory \"\/var\/www\/html\">
Require all granted
Require not ip 12.23.34.45
Require not ip 20.0.255.255\/16
<\/Directory><\/pre>\n\n\n\nWhen you add the above statements to a Directory block, it will be applicable to all sub directories and files present in it. If you add it to File block, it will be applicable only to the said file. If you use it in Location block, then it will be applicable to all URLs served by that block.<\/p>\n\n\n\n
