PLEASE READ CONFIGURATION INSTRUCTIONS BELOW THOROUGHLY

If you miss one step you will get an nginx EMERG error. This is normally a result of not downloading either blockbots.conf, ddos.conf, whitelist-ips.conf, whitelist-domains.conf, bad-referrer-words.conf, custom-bad-referrers.conf, blacklist-user-agents.conf or blacklist-ips.conf into your /etc/nginx/bots.d folder. If any of the include files are missing Nginx will EMERG and will not reload.

AUTO INSTALLATION INSTRUCTIONS

It is HIGHLY SUGGESTED to please use the auto installation scripts created by Stuart Cardall @itoffshore Please see: https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/blob/master/AUTO-CONFIGURATION.md or https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/blob/master/README.md

MANUAL INSTALLATION INSTRUCTIONS

STEP 1:

COPY THE GLOBALBLACKLIST.CONF FILE FROM THE REPO

Copy the contents of /conf.d/globalblacklist.conf into your /etc/nginx/conf.d folder.

cd /etc/nginx/conf.d

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/conf.d/globalblacklist.conf -O globalblacklist.conf

STEP 2:

COPY THE INCLUDE FILES FROM THE REPO

  • From your command line in Linux type

sudo mkdir /etc/nginx/bots.d

cd /etc/nginx/bots.d

  • copy the all the following files into that folder

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/blockbots.conf -O blockbots.conf sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/ddos.conf -O ddos.conf

STEP 3:

WHITELIST ALL YOUR OWN DOMAIN NAMES AND IP ADDRESSES

Whitelist all your own domain names and IP addresses. Please note important changes, this is now done using include files so that you do not have to keep reinserting your whitelisted domains and IP addresses every time you update.

cd /etc/nginx/bots.d

  • copy the whitelist-ips.conf file into that folder

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/whitelist-ips.conf -O whitelist-ips.conf

  • copy the whitelist-domains.conf file into the same folder

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/whitelist-domains.conf -O whitelist-domains.conf

Use nano, vim or any other text editor to edit both whitelist-ips.conf and whitelist-domains.conf to include all your own domain names and IP addresses that you want to specifically whitelist from the blocker script. When pulling any future updates now your domains and IP whitelists will not be overwritten.

STEP 4:

BLACKLIST USING YOUR OWN CUSTOM USER-AGENT BLACKLIST

Copy the custom User-Agents blacklist file into your /etc/nginx/bots.d folder

cd /etc/nginx/bots.d

  • copy the blacklist-user-agents.conf file from the repository

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/blacklist-user-agents.conf -O blacklist-user-agents.conf

Use nano, vim or any other text editor to edit (if needed) blacklist-user-agents.conf to include your own custom list of bad agents that are not included in the blocker like "omgilibot" which some people choose to block. When pulling any future updates now your custom User-Agents blacklist will not be overwritten.

STEP 5:

BLACKLIST USING YOUR OWN CUSTOM BAD REFERRERS

Copy the custom bad referrers blacklist file into your /etc/nginx/bots.d folder

cd /etc/nginx/bots.d

  • copy the custom-bad-referrers.conf file from the repository

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/custom-bad-referrers.conf -O custom-bad-referrers.conf

Use nano, vim or any other text editor to edit (if needed) custom-bad-referrers.conf to include your own custom list of bad referrer domains that are not included in the blocker. When pulling any future updates now your custom referrers list will not be overwritten.

STEP 6:

BLACKLIST IPS AND IP RANGES USING YOUR OWN CUSTOM LIST

Copy the custom IP blacklist file into your /etc/nginx/bots.d folder

cd /etc/nginx/bots.d

  • copy the blacklist-ips.conf file from the repository

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/blacklist-ips.conf -O blacklist-ips.conf

Use nano, vim or any other text editor to edit (if needed) blacklist-ips.conf to include your own custom list of IP Addresses and IP Ranges that you wish to block.
When pulling any future updates now your custom IP blacklist will not be overwritten.

STEP 7:

DOWNLOAD CUSTOM BAD REFERRER WORDS INCLUDE FILE FOR CUSTOMIZED SCANNING OF BAD WORDS

Copy the custom bad referrer words include file into your /etc/nginx/bots.d folder

cd /etc/nginx/bots.d

  • copy the bad-referrer-words.conf file from the repository

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/bots.d/bad-referrer-words.conf -O bad-referrer-words.conf

Use nano, vim or any other text editor to edit the bad-referrer-words.conf file as you like. When pulling any future updates now your custom bad referrer words list will not be overwritten.

STEP 8:

INCLUDE IMPORTANT SETTINGS IN NGINX.CONF Also see SAMPLE-nginx.conf file in the root of this repository

cd /etc/nginx/conf.d

  • copy the botblocker-nginx-settings.conf file directly from the repo

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/conf.d/botblocker-nginx-settings.conf -O botblocker-nginx-settings.conf

What is included in this settings file above for nginx? The important settings file above adds the rate limiting functions and hash_bucket settings for nginx for you. Below is what the file contains, you cn add these manually to your nginx.conf file if you so please but the include file above will do it for you ad nginx loads any .conf file in /etc/conf.d (See STEP 6)

server_names_hash_bucket_size 64;

server_names_hash_max_size 4096;

limit_req_zone $binary_remote_addr zone=flood:50m rate=90r/s;

limit_conn_zone $binary_remote_addr zone=addr:50m;

PLEASE NOTE: The above rate limiting rules are for the DDOS filter, it may seem like high values to you but for wordpress sites with plugins and lots of images, it's not. This will not limit any real visitor to your Wordpress sites but it will immediately rate limit any aggressive bot. Remember that other bots and user agents are rate limited using a different rate limiting rule at the bottom of the globalblacklist.conf file.

The server_names_hash settings allows Nginx Server to load this very large list of domain names and IP addresses into memory. You can tweak these settings to your own requirements.

STEP 9: VERY IMPORTANT

MAKE SURE that your nginx.conf file contains the following include directive. If it's commented out make sure to uncomment it or none of this will work.

  • include /etc/nginx/conf.d/*

STEP 10: VERY IMPORTANT

ADD INCLUDE FILES INTO A VHOST

Open a site config file for Nginx (just one for now) and add the following lines.

VERY IMPORTANT NOTE:

These includes MUST be added within a server {} block of a vhost otherwise you will get EMERG errors from Nginx.

  • include /etc/nginx/bots.d/blockbots.conf;

  • include /etc/nginx/bots.d/ddos.conf;

STEP 11:

TESTING YOUR NGINX CONFIGURATION

sudo nginx -t

If you get no errors then you followed my instructions so now you can make the blocker go live with a simple.

sudo service nginx reload

The blocker is now active and working so now you can run some simple tests from another linux machine to make sure it's working.

STEP 12:

TESTING

Run the following commands one by one from a terminal on another linux machine against your own domain name. substitute yourdomain.com in the examples below with your REAL domain name

curl -A "googlebot" http://yourdomain.com

Should respond with 200 OK

curl -A "80legs" http://yourdomain.com

curl -A "masscan" http://yourdomain.com

Should respond with: curl: (52) Empty reply from server

curl -I http://yourdomain.com -e http://100dollars-seo.com

curl -I http://yourdomain.com -e http://zx6.ru

Should respond with: curl: (52) Empty reply from server

The Nginx Ultimate Bot Blocker is now WORKING and PROTECTING your web sites !!!

STEP 13:

UPDATING THE NGINX BAD BOT BLOCKER is now easy thanks to the automatic includes for whitelisting your own domain names.

Updating to the latest version is now as simple as:

cd /etc/nginx/conf.d

sudo wget https://raw.githubusercontent.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/master/conf.d/globalblacklist.conf -O globalblacklist.conf

sudo nginx -t

sudo service nginx reload

And you will be up to date with all your whitelisted domains included automatically for you now.

Relax now and sleep better at night knowing your site is telling all those baddies they are FORBIDDEN !!!

PULL REQUESTS:

To contribute your own bad referers, bots or to make corrections to any incorrectly blocked bots or domains please fork a copy of this repository and send pull requests on the individual files located in https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker/tree/master/_generator_lists and then send a pull request (PR).

Additions, Removals and Corrections will all be checked for accuracy before being merged into main blocker.

ISSUES:

Log any issues regarding incorrect listings or any other problems on the issues system and they will be investigated and removed if necessary. I responde very quickly to user problems and have helped countless users for days on end to get their bot blocker working. You could say I am mad (disputable) but I love helping people and do not ignore issues or people with problems getting this to work.

Coding makes me very thirsty why not buy me a beer🍺
