Tsinghua University Mirror Configuration

Ubuntu image address: Tsinghua University Open Source Software Mirror

  1. Configure the Mirror Source

The software source configuration file for Ubuntu is /etc/apt/sources.list.

# By default, source mirrors are commented out to improve the speed of apt update. Uncomment them if needed.
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse

Some Common Commands

  1. Go to a specific location: cd /home/
  2. List the current directory: ls
  3. sudo apt install [pkgName]
  4. sudo apt update

Install PostgreSQL 14

Because the official default is postgresql-12, you need to configure the PostgreSQL source:

# Create the file repository configuration:
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

# Import the repository signing key:
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

# Update the package lists:
sudo apt-get update

# Install the latest version of PostgreSQL.
# If you want a specific version, use 'postgresql-12' or similar instead of 'postgresql':

sudo apt-get -y install postgresql-16

Install OpenJDK 11

# Install JRE
sudo apt-get -y install openjdk-11-jre

# Install JDK
sudo apt-get -y install openjdk-11-jdk-headless
