Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install MariaDB/MySQL
  1. Install using the official repo:

    sudo yum install -y mariadb-server
    sudo systemctl start mariadb
    sudo systemctl enable mariadb
    sudo mysql_secure_installation
Create required resources
  1. Log in to the server:

    mysql -u root -p
  2. Then, create the database and the table:

    create database city_data;
    use city_data
    create table city_info(
    LatD int,
    LatM int,
    LatS int,
    NS char,
    LonD int,
    LonM int,
    LonS int,
    EW char,
    City varchar(50),
    State varchar(50)
    ) ;
Bulk insert and validate the data
  1. Copy the cities.csv file into the mysql user’s home directory:

    sudo cp ./data/cities.csv /var/lib/mysql
  2. Perform the bulk insert:

    LOAD DATA INFILE '/var/lib/mysql/cities.csv' INTO table city_info Fields terminated by ',' ENclosed by '"' Lines terminated by 'n' Ignore 1 ROWS;
  3. Validate the data:

    select count(city) from city_info where state='KS';

Additional Resources

Your development team has requested an installation of MariaDB/MySQL on a CentOS7 server.
Once it has been installed and configured, you will be required to create a database named city_data.
In this database, you are to create a table named city_info and then bulk import the data located in /home/cloud_user/data/cities.csv.

Once this is complete, you will need to ensure that the data is present by validating that there are 3 cities in Kansas (KS).
