mysql installation version configuration

MySQL is currently one of the most widely used relational databases. It is easy to operate, stable, reliable, and highly secure, and has been widely favored by many developers. This article will introduce the configuration process of the MySQL installation version for beginners' reference.

1. Download and install MySQL

Download the free installation version of MySQL from the official website and follow the installation wizard to install it. Select Full Installation to install the client and server sides of MySQL, as well as other related components.

2. Configure MySQL

1. Set the root user password

In MySQL, the root user has super privileges, so its password must be set to ensure safety. First open the MySQL command line client and enter the following command in the command line:

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yourpassword');

Replace yourpassword in the above command with the password you want to set. When finished typing, press Enter.

2. Modify the character set

In MySQL, the character set is one of the very important settings because it directly affects the storage and processing of data. The Latin1 character set is used by default in MySQL. If you need to use other character sets such as UTF-8, you can configure it in my.ini.

Open the my.ini file, find the [mysqld] section, and add the following content:

[mysqld]
character-set-server = utf8
collation-server = utf8_general_ci

3. Configure the connection method

In the my.ini file , you can configure the MySQL connection method. If you need to allow remote connections, you need to add the following:

[mysqld]
bind-address = 0.0.0.0

Among them, 0.0.0.0 means allowing all connections. If you need to limit the number of connections, you can set max_connections in the my.ini file.

4. Configuring logging

MySQL supports multiple types of logging, such as error logs, slow query logs, etc. These logs are very important for MySQL operation, maintenance and tuning. You can configure the following content in the my.ini file:

[mysqld]
log-error = D:/mysql/mysql-8.0.25-winx64/mysql_error.log
slow-query-log = D:/mysql/mysql-8.0.25-winx64/mysql_slow.log

Among them, log-error represents the error log, and slow-query-log represents the slow query log. What needs to be noted here is that the path needs to be replaced with your actual path.

5. Configuring cache size

The cache size of MySQL also has a very important impact on database performance. The following parameters can be configured in the [mysqld] section of the my.ini file:

[mysqld]
query_cache_size = 16M

Among them, the query_cache_size parameter represents the cache size, and 16M represents 16MB.

6. Configuring key authentication

In addition to password authentication, MySQL also supports the use of key authentication, which improves security. Add the following parameters in the my.ini file:

[mysqld]
ssl-ca = D:/mysql/mysql-8.0.25-winx64/ca.pem
ssl-cert = D:/mysql/mysql-8.0.25-winx64/server-cert.pem
ssl-key = D:/mysql/mysql-8.0.25-winx64/server-key.pem

Where ssl-ca represents the CA certificate, ssl-cert represents the server certificate, and ssl-key represents the server key. What needs to be noted here is that you need to generate the certificate and key yourself and place them in the corresponding path.

3. Start MySQL

After all configurations are completed, you can start MySQL. Find the bin directory under the MySQL installation directory and start the MySQL service:

D:mysqlmysql-8.0.25-winx64in>mysqld

If the service is started successfully, the command line will remain running until the MySQL service is manually stopped.

The above is the configuration process of the MySQL installation version. In actual applications, we need to configure it according to specific application requirements to ensure the high performance and high reliability of the MySQL database.
