CentOS is a Linux distribution compiled based on Red Hat Enterprise Linux (RHEL), so you can use RHEL's package management tools (such as Yum) to install, upgrade, and delete software packages. MySQL is a widely used relational database management system. This article will introduce how to install MySQL through rpm on CentOS system.
Select the appropriate version of the MySQL software package to download from the MySQL official website. Here, MySQL Community Server 8.0.25 is taken as an example. The download address is https://dev.mysql.com/downloads/mysql/.
According to the number of bits configured in the system (32-bit or 64-bit), select the corresponding compressed package to download. Here we choose the rpm package of CentOS 7 64-bit version.
After the download is completed, you can use the following command to install the rpm package:
# 安装MySQL服务器 sudo rpm -Uvh mysql-community-server-8.0.25-1.el7.x86_64.rpm # 安装MySQL客户端 sudo rpm -Uvh mysql-community-client-8.0.25-1.el7.x86_64.rpm
At this point, MySQL has been successful Installed on CentOS system.
After installing MySQL, you need to start the MySQL service through the systemctl command. Use the following command to start the MySQL service:
sudo systemctl start mysqld
In order to automatically start the MySQL service after each system startup, you can run the following command:
sudo systemctl enable mysqld
Before starting the MySQL service, you need to set the password of the MySQL administrator through the following command:
sudo mysql_secure_installation
After execution, you will be asked to enter the initial password. If this is the first installation, the MySQL administrator account does not have a password, just press Enter.
You will then need to enter a new password. Require strong passwords and avoid simple passwords. Please follow the prompts and set a password of at least 8 characters.
Next, you need to answer some security questions:
After setting up, restart the MySQL service to make the changes take effect:
sudo systemctl restart mysqld
Now, you can enter the MySQL database through the following methods:
mysql -u root -p
Enter the administrator password After that, you will enter the MySQL command line prompt.
