Kloxo-MR Technical Helps / How to configure nginx geoIP logs
« on: 2021-07-15, 21:54:47 »
Install nginx-module-geoip:

Code: [Select]
yum -y install nginx-module-geoip
Download GeoIP files:

Code: [Select]
mkdir /etc/nginx/geoip;
cd /etc/nginx/geoip;
wget https://mailfud.org/geoip-legacy/GeoIP.dat.gz
wget https://mailfud.org/geoip-legacy/GeoIPCity.dat.gz
gunzip GeoIP.dat.gz;
gunzip GeoIPCity.dat.gz

Add script to update GeoIP files:

Code: [Select]
cd ~;
wget https://mailfud.org/geoip-legacy/geoip_update.sh;

Change lines:

Code: [Select]
DBDIR=/usr/share/GeoIP
FILES="GeoIP GeoIPv6"

to:

Code: [Select]
DBDIR=/etc/nginx/geoip
FILES="GeoIP GeoIPCity"

Add a line to /var/spool/cron/root:

Code: [Select]
* 3 * * * sh /root/geoip_update.sh
You can run the script manually to check if all is working fine:

Code: [Select]
sh /root/geoip_update.sh
It should respond with something like this:

Code: [Select]
2021-07-15 22:36:59 URL:https://mailfud.org/geoip-legacy/GeoIP.dat.gz [1076511/1076511] -> "GeoIP.dat.gz" [1]
GeoIP.dat is up to date
2021-07-15 22:37:00 URL:https://mailfud.org/geoip-legacy/GeoIPCity.dat.gz [17027045/17027045] -> "GeoIPCity.dat.gz" [1]
GeoIPCity.dat is up to date

Add in /etc/nginx/nginx.conf line on top and copy the file to /opt/configs/nginx/etc/conf/custom.nginx.conf:

Code: [Select]
load_module "modules/ngx_http_geoip_module.so";
and also at the end before "include" these lines:

Code: [Select]
geoip_country /etc/nginx/geoip/GeoIP.dat; # the country IP database
geoip_city /etc/nginx/geoip/GeoIPCity.dat; # the city IP database

Add the following lines to /etc/nginx/fastcgi_params and copy the file to /opt/configs/nginx/etc/conf/custom.fastcgi_params before # PHP only line:

Code: [Select]
### SET GEOIP Variables ###
fastcgi_param GEOIP_COUNTRY_CODE $geoip_country_code;
fastcgi_param GEOIP_COUNTRY_CODE3 $geoip_country_code3;
fastcgi_param GEOIP_COUNTRY_NAME $geoip_country_name;

fastcgi_param GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
fastcgi_param GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;
fastcgi_param GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name;
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_CITY $geoip_city;
fastcgi_param GEOIP_POSTAL_CODE $geoip_postal_code;
fastcgi_param GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
fastcgi_param GEOIP_LATITUDE $geoip_latitude;
fastcgi_param GEOIP_LONGITUDE $geoip_longitude;

Change the following lines in /etc/nginx/conf.d/~lxcenter.conf and copy the file to /opt/configs/nginx/etc/conf.d:

Code: [Select]
   log_format main '$remote_addr - $remote_user [$time_local] "$request" '
        '$status $body_bytes_sent "$http_referer" '
        '"$http_user_agent" "$http_x_forwarded_for"';

to

Code: [Select]
  log_format main '$remote_addr - $remote_user [$time_local] "$request" '
        '$status $body_bytes_sent "$http_referer" '
        '"$http_user_agent" "$http_x_forwarded_for" '
        '"$geoip_country_name" "$geoip_country_code" ';

Finally restart nginx with:

Code: [Select]
service nginx restart
Now you can try checking your logs and you will something like this. At the end you will notice country and country code is listed e.g. "United Kingdom" "GB":

Code: [Select]
80.1.2.62 - - [15/Jul/2021:21:49:15 +0200] "GET /p3700/Clipboard02.jpg HTTP/1.1" 200 71231 "https://vi.vipr.ebaydesc.com/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36" "-" "United Kingdom" "GB"
If you use IPv6 on your server you need to also use GeoIPv6 and GeoIPCityv6.

newServer({address='127.0.0.1:5300', pool='auth'})
newServer({address='127.0.0.1:5301', pool='recursor'})

recursive_ips = newNMG()
recursive_ips:addMask('127.0.0.1') -- These network masks are the ones from allow-recursion in the Authoritative Server

addAction(NetmaskGroupRule(recursive_ips), PoolAction('recursor'))
addAction(AllRule(), PoolAction('auth'))

7. Restart everything:

Code: [Select]

1. Logon to Kloxo-MR panel.

2. Go to Domains -> yourdomain.com -> Pointer domains -> Click Add Redirected tab

3. In Pointer Domain type mta-sts in Destination Directory type anything like contact (this is just technical domain and will show 404 error). Leave Map Mail untouched.

4. Go to Mail accounts and add these e-mails tlsrpt@yourdomain.com and mta-sts@yourdomain.com. You can redirect them by clicking on them and choosing Mail forwards and typing Mail Forward Address.

5. Go to Domains -> yourdomain.com -> Manage DNS -> Add TXT:

_mta-sts as hostname and Value v=STSv1; id=20210806155900

Then again Add TXT:

_smtp._tls as hostname and Value  v=TLSRPTv1; rua=mailto:tlsrpt@yourdomain.com

6. Go to Domains -> yourdomain.com -> SSL Certificates. If you have your SSL already remove it. Click Add Let's Encrypt, leave default Key Bits 2048 and add mta-sts.yourdomain.com to Subject Alternative Name (SAN) list, then click Add.

7. Logon via SSH and create /var/run/letsencrypt/.well-known/mta-sts.txt with such content:

version: STSv1
mode: enforce
mx: mail.yourdomain.com
mx: *.yourdomain.com
max_age: 31557600

8. Check if all is working properly here: https://aykevl.nl/apps/mta-sts/

1. Add such line to /etc/pdns/pdns.conf:

Code: [Select]
gmysql-dnssec=yes
2. Restart PowerDNS with service pdns restart.

3. Open phpMyAdmin under https://YOUR_IP:7777/thirdparty/phpMyAdmin/index.php and login as root.

4. Select powerdns database and click SQL tab.

5. Enter:

Code: [Select]
ALTER table cryptokeys add column published BOOL DEFAULT 1 after active;
6. Go back to SSH terminal and type:

Code: [Select]
pdnsutil secure-zone yourdomain.com
7. Show DS keys:

Code: [Select]
pdnsutil show-zone yourdomain.com | grep CSK
Key ID is the number right after IN DNSKEY

Public key is the large string after 13 in a second line

8. Now go to your domain register e.g. online.net and in domain settings DNSSEC tab use such settings:

Quote
Key ID: 257 (or other as noted above)

Quote
Algorithm: 13/ ECDSAP256SHA256

Quote
Public key: copy the whole key (long string) after 13 and before ; from second line

You can verify on https://www.hardenize.com just enter domain name and hit ENTER

It should respond with:

Test passed
Everything seems to be well configured. Well done.

in DNSSEC section.

9. If you have subdomains with their own zones (e.g. extra subdomains via Kloxo) secure them too with:

Code: [Select]
pdnsutil secure-zone subdomain.yourdomain.com
10. Then list the subdomain zone with:

pdnsutil show-zone subdomain.yourdomain.com | grep DS

11. This will give you something like this, copy last 4 lines:

Code: [Select]
ID = 6 (CSK), flags = 257, tag = 20164, algo = 13, bits = 256     Active         Published  ( ECDSAP256SHA256 )
CSK DNSKEY = subdomain.yourdomain.com 777600 IN DNSKEY 257 3 13 lnOLSuqVqvCUVDgBHjxz5yhXlcX0kbbZ8sSdpBrb1bUAlAqelea47b36+YGrn4HHKE/fqk6tH0MNQdWNBZOtPg== ; ( ECDSAP256SHA256 )
DS = subdomain.yourdomain.com 777600 IN DS 20164 13 1 225e6a7160c9ce428c6212a122aa3d3d91af67c3 ; ( SHA1 digest )
DS = subdomain.yourdomain.com 777600 IN DS 20164 13 2 9f182e93515314797a310d574b681010b473830d8e7772993ee373353bb5cc01 ; ( SHA256 digest )

I simply used php branch. It sets default php version to 7.3.13.

PHP 7.4 is not possible on CentOS 6.10. Remi refused to compile it. Too much hassle.

That's not true. I use CentOS 6.10 with PHP 7.3.13 from remi repo. Only PHP 7.4 is not possible.
