MySQL is a relational database management system that is widely used in background data management of web applications. When doing application development or testing, we often need to run a MySQL server in a local environment. MySQL officially provides an executable program installation package, but in some cases, we may need to use the installation-free version of MySQL server. This article will introduce you how to configure the installation-free version of MySQL.
Step 1: Download MySQL installation-free version
First, you need to download the portable version of MySQL server. You can download the file for your operating system from the MySQL official website. Once downloaded, you can unzip the file to any location you like. Note that these versions do not include the MySQL GUI tools or installer, you will need to configure and start the server manually.
Step 2: Create the data directory
Let’s start setting up the server. In the root directory of the MySQL server, we need to create a data directory to save MySQL data. Within the data directory, you can create subdirectories to house different databases. For example, to create a data directory named "test", follow these steps:
- Create a directory named "data" under the MySQL Server root directory, which will be used for Stores all MySQL data.
- Create a my.ini file in the root directory of MySQL Server. This is the configuration file of the MySQL server.
In this file, we need to set the location of the MySQL data directory. To do this, add the following line:
[mysqld]
datadir=C:/MySQL Server/data
- Double-click the directory data and create it under the name test folder.
In this way, you can see a database named test in the MySQL server.
Step Three: Configure MySQL Server
Next, we need to configure the MySQL server so that it can run on the local computer. In the my.ini file, we need to add the following:
[mysqld]
port=3306
default-character-set=utf8
default-storage-engine=INNODB
skip-name-resolve
You can adjust the port number and character encoding as needed. Note that name resolution is skipped, which will make the MySQL server run faster.
Step 4: Start the MySQL server
The next step is to start the MySQL service. For the installation-free version, starting the MySQL server is very simple. Just enter the MySQL bin folder in CMD, enter cmd in the address bar of the folder path, and then enter the following command after the bin folder path to successfully start the MySQL server:
mysqld -- console
You can enable remote access in the my.ini file so that your application can access the MySQL server from a remote computer.
Step 5: Connect to the MySQL server
Now, the MySQL server is ready and you can use the MySQL client to connect to it. We recommend using MySQL client command operations. You can find the MySQL client in the bin directory and use the following command to log in to the MySQL server:
mysql -u root -p
In the above command, "root" is the user name, system You will be prompted for your password. If your MySQL server does not set a password, you can press Enter to skip the password.
Finally, you can use the following command to create a new database:
create database test;
Now that you have successfully configured the installation-free MySQL server, start using it. !

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
