How to connect Mariadb database using Python?

To connect to a MariaDB database from Python, you will need to install the mysql-connector-python package, which is a MariaDB Connector that implements the Python Database API v2.0 (PEP 249). Once you have that installed, you can use the following steps to connect to a MariaDB database from your Python code:

Import the mysql.connector module, which contains the connect() function that is used to connect to a MariaDB database.

import mysql.connector
  1. Create a mysql.connector.connect() instance, which represents a connection to a MariaDB database. You will need to specify the following arguments to the connect() function:
  • host: The hostname or IP address of the MariaDB server.
  • user: The username to use when connecting to the MariaDB server.
  • password: The password to use when connecting to the MariaDB server.
  • database: The name of the MariaDB database that you want to connect to.
cnx = mysql.connector.connect(
host="hostname",
user="username",
password="password",
database="database"
)
  1. Once the connection is established, you can use the cnx object to execute SQL statements and manage the connection to the MariaDB database. For example, you can create a mysql.connector.cursor.MySQLCursor object to execute SQL statements and retrieve the results of your queries:
cursor = cnx.cursor()

query = "SELECT * FROM table"
cursor.execute(query)

result = cursor.fetchall()
  1. When you are done working with the MariaDB database, you should close the cursor and the connection to the database using the close() method:
cursor.close()
cnx.close()

Creating Multiple VLANs over Bonding Interfaces with Proper Routing on a Centos Linux Host

In this post, I am going to explain configuring multiple VLANs on a bond interface. First and foremost, I would like to describe the environment and give details of the infrastructure. The server has 4 Ethernet links to a layer 3 switch with names: enp3s0f0, enp3s0f1, enp4s0f0, enp4s0f1 There are two bond interfaces both configured as active-backup bond0, bond1 enp4s0f0 and enp4s0f1 interfaces are bonded as bond0. Bond0 is for making ssh connections and management only so corresponding switch ports are not configured in trunk mode. enp3s0f0 and enp3s0f1 interfaces are bonded as bond1. Bond1 is for data and corresponding switch ports are configured in trunk mode. Bond0 is the default gateway for the server and has IP address 10.1.10.11 Bond1 has three subinterfaces with VLAN 4, 36, 41. IP addresses are 10.1.3.11, 10.1.35.11, 10.1.40.11 respectively. Proper communication with other servers on the network we should use routing tables. There are three

Listing Zimbra Accounts with Some Details

Recently I have to export the user list for a particular domain. Luckily Zimbra has Admin GUI with a search feature. When you search accounts, you can download search results as a comma-separated csv file. So I did a search and download the result file, but the result did not have all the columns I need and also there is no option for customizing columns for search results. So I had to write a bash script to get the desired list. Here is the bash script ( It can be customized by adding or removing field names. Run it under zimbra user like ./zimbra_account_list.sh <domain_name_here> ):
