Step‑by‑Step: Install MySQL 8.0/8.4 on Ubuntu 24.04 and Debian 11/12

Installing MySQL from the Apt Repository

This section describes how to install MySQL 8.0 or 8.4 on Ubuntu 24.04 and Debian 11/12 using the official MySQL APT repository.

1. Add the MySQL APT repository

Download the repository package and install it with dpkg. On Debian you may need to install gnupg first.

# wget https://dev.mysql.com/get/mysql-apt-config_0.8.34-1_all.deb
# dpkg -i mysql-apt-config_0.8.34-1_all.deb
# apt update

2. Choose the MySQL version

During the dpkg configuration, use the arrow keys to select the desired version (e.g., mysql-8.0 or mysql-8.4-lts) and confirm with Enter.

3. Install MySQL server

# apt install -y mysql-community-server

4. Enable and start the service

# systemctl enable --now mysql

5. Verify the installation

# mysql -V
# systemctl status mysql
# mysql -e "SHOW DATABASES;"
# mysql -e "STATUS;"

Typical output shows the MySQL version (e.g., 8.0.43‑0ubuntu0.24.04.2 or 8.4.6‑1ubuntu24.04), confirms the service is active, and lists the default databases ( information_schema, mysql, performance_schema, sys).

6. Optional: Replace the default repository with a domestic mirror

# sed -i.bak 's|http://repo.mysql.com|https://mirrors.nju.edu.cn/mysql|g' /etc/apt/sources.list.d/mysql.list
# apt update

After the mirror change, repeat step 3 to install the server from the new source.
