Here is a guide for users to fully automate the updating of their IP2Location DB24 IPv6 database. We will show how to download the IP2Location DB24 IPv6 CSV data from the web server and then unzip it before loading the data into a MySQL server on a Linux platform. We will explain what each part of the code does as we go through the whole process.
Configure login details
Firstly, we need to set up some login details for the IP2Location web server as well as the MySQL server information. Under the Configuration section of the script, you will need to key in all the relevant login information in the fields below:
# Configuration TOKEN="DOWNLOAD_TOKEN" CODE="DB24IPV6" DBHOST="YOUR_DATABASE_HOST" DBUSER="YOUR_DATABASE_USERNAME" DBPASS="YOUR_DATABASE_PASSWORD" DBNAME="YOUR_DATABASE_NAME"
For most cases, you shouldn’t have to modify anything else in the script but we will still explain what is going on in case you want to modify the code.
Checking for pre-requisites
Some Linux packages like wget, unzip, mysql, wc, find and grep are needed for this script to run. If any of them are not installed, an error message will be shown and the script will terminate itself.
for a in wget unzip mysql wc find grep; do if [ -z "$(which $a)" ]; then error "Command \"$a\" not found." exit 0 fi done
Creating the temporary folder for storing the downloaded zipped data file
If the temporary folder does not exist, it will be created. An error message will be shown if the folder cannot be created and the script will terminate itself.
if [ ! -d /tmp/ip2location ]; then echo -n "Create temporary directory.......................... " mkdir /tmp/ip2location if [ ! -d /tmp/ip2location ]; then error "Failed to create /tmp/ip2location" exit 0 fi success "[OK]" fi
Downloading the zipped data file from the web server
If download is not successful then an error message will be shown and the script will terminate itself.
wget -O database.zip -q https://www.ip2location.com/download?token=$TOKEN\&file=$CODE 2>&1 if [ ! -f database.zip ]; then error "Download failed." exit 0 fi if [ ! -z "$(grep 'NO PERMISSION' database.zip)" ]; then error "Permission denied." exit 0 fi if [ ! -z "$(grep '5 times' database.zip)" ]; then error "Download quota exceed." exit 0 fi if [ $(wc -c < database.zip) -lt 102400 ]; then error "Download failed." exit 0 fi
Decompressing the zipped file
If decompression is not successful then an error message will be shown and the script will terminate itself.
unzip -q -o database.zip if [ -z $(find . -name 'IPV6-COUNTRY*.CSV') ]; then echo "ERROR:" exit 0 fi NAME="$(find . -name 'IPV6-COUNTRY*.CSV')"
Creating a temporary table in MySQL to load the data
Drops the temporary table if it already exists and then creates the table. If an error is encountered, an error message will be shown and the script will terminate itself.
RESULT="$(mysql -h $DBHOST -u $DBUSER -p$DBPASS $DBNAME -e 'DROP TABLE IF EXISTS `ip2location_database_tmp`;' 2>&1)" if [ ! -z "$(echo $RESULT | grep 'connect')" ]; then error "Failed to connect MySQL host." exit 0 fi if [ ! -z "$(echo $RESULT | grep 'Access denied')" ]; then error "MySQL authentication failed." exit 0 fi RESULT="$(mysql -h $DBHOST -u $DBUSER -p$DBPASS $DBNAME -e 'CREATE TABLE `ip2location_database_tmp` (`ip_from` DECIMAL(39,0) NOT NULL,`ip_to` DECIMAL(39,0) NOT NULL,`country_code` CHAR(2) NOT NULL,`country_name` VARCHAR(64) NOT NULL,`region_name` VARCHAR(128) NOT NULL,`city_name` VARCHAR(128) NOT NULL,`latitude` DOUBLE NULL DEFAULT NULL,`longitude` DOUBLE NULL DEFAULT NULL,`zip_code` VARCHAR(12) NULL DEFAULT NULL,`time_zone` VARCHAR(8) NULL DEFAULT NULL,`isp` VARCHAR(255) NOT NULL,`domain` VARCHAR(128) NOT NULL,`net_speed` VARCHAR(8) NOT NULL,`idd_code` VARCHAR(5) NOT NULL,`area_code` VARCHAR(30) NOT NULL,`weather_station_code` VARCHAR(10) NOT NULL,`weather_station_name` VARCHAR(128) NOT NULL,`mcc` VARCHAR(128) NULL DEFAULT NULL,`mnc` VARCHAR(128) NULL DEFAULT NULL,`mobile_brand` VARCHAR(128) NULL DEFAULT NULL,`elevation` INT(10) NOT NULL,`usage_type` VARCHAR(11) NOT NULL,PRIMARY KEY (`ip_to`)) ENGINE=MyISAM;' 2>&1)" if [ ! -z "$(echo $RESULT)" ]; then error "Unable to create temporary table." exit 0 fi
Loading the CSV data into the MySQL temporary table
Loads the CSV data into the temporary table. If an error is encountered, an error message will be shown and the script will terminate itself.
RESULT="$(mysql -h $DBHOST -u $DBUSER -p$DBPASS $DBNAME -e 'LOAD DATA LOCAL INFILE '\'''$NAME''\'' INTO TABLE `ip2location_database_tmp` FIELDS TERMINATED BY '\'','\'' ENCLOSED BY '\''\"'\'' LINES TERMINATED BY '\''\r\n'\'';' 2>&1)" if [ ! -z "$(echo $RESULT)" ]; then error "Failed." exit 0 fi
Dropping the existing data table
Drops the existing data table. If an error is encountered, an error message will be shown and the script will terminate itself.
RESULT="$(mysql -h $DBHOST -u $DBUSER -p$DBPASS $DBNAME -e 'DROP TABLE IF EXISTS `ip2location_database`;' 2>&1)" if [ ! -z "$(echo $RESULT)" ]; then error "Failed to drop \"ip2location_database\" table." exit 0 fi
Rename the temporary table to become the live data table
Renames the temporary table to become the live data table. If an error is encountered, an error message will be shown and the script will terminate itself.
RESULT="$(mysql -h $DBHOST -u $DBUSER -p$DBPASS $DBNAME -e 'RENAME TABLE `ip2location_database_tmp` TO `ip2location_database`;' 2>&1)" if [ ! -z "$(echo $RESULT)" ]; then error "Failed to rename table." exit 0 fi
Remove temporary download folder and the downloaded data file
Remove the temporary download folder and all files in that folder.
rm -rf /tmp/ip2location
