Introduction MySQL manages connections to the database server through socket file. This file helps in communications between different processes in MySQL. This file is called mysqld.sock. In the Linux systems it’s stored in /var/run/mysqld/ directory. If you face a socket error, the foremost solution is to restart $ sudo systemctl start mysql … $ sudo systemctl restart mysql Let us frsst verify where is the instllation of MySQL is done $ sudo nano /etc/mysql/mysql.conf.d/mysql.cnf Output should be like this /etc/mysql/mysql.conf.d/mysqld.cnf . . . [mysqld] user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 . . . Now…

1. Check CRASH ADDRESS in MySQL Problem Insufficient Memory is one of the major reason in SQL crash, i recommend to review the MySQL error log . $ sudo systemctl start mysql To review crash error logs: $ sudo less /var/log/mysql/error.log Solution Reducing your web application’s dependency . You can simply do it by adding static caching to your application. For an Examples JOOMLA, which has caching built-in feature that can be enabled also a WP Super Cache, a WordPress plugin will also reduce web application dependecny. Upgrading Virtual Private server storage size I recommend minmum 1GB of RAM for server using …

Introduction We are going to create a Battleship Game Code in Python. This project is not beginner friendly for python learners who just started learning python. This game is the single-player battleship code written in Python programming language. In this source code of the battleship game in python, we have made used grids. This grid consists of 7 rows and 7 columns of the battleship where you can destroy and sink the ships. This battleship game written in python is really interesting and challenging. The python learners must try this and get the code executed on the online compiler or…
