ubuntu安装PostgreSQL

官网：

https://www.postgresql.org/

配置ubuntu源等信息

https://www.postgresql.org/download/linux/ubuntu/

配置信息可以写成脚本安装

vim install_PostgreSQL.sh

写入一下内容，这里的内容根据官网的内容来复制，版本会更新

# Import the repository signing key:
sudo apt install curl ca-certificates
sudo install -d /usr/share/postgresql-common/pgdg
sudo curl -o /usr/share/postgresql-common/pgdg/apt.postgresql.org.asc --fail https://www.postgresql.org/media/keys/ACCC4CF8.asc

# Create the repository configuration file:
sudo sh -c 'echo "deb [signed-by=/usr/share/postgresql-common/pgdg/apt.postgresql.org.asc] https://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

# Update the package lists:
sudo apt update

# Install the latest version of PostgreSQL:
# If you want a specific version, use 'postgresql-16' or similar instead of 'postgresql'
sudo apt -y install postgresql

安装好以后进入到postgres用户里面初始化数据库

su - postgres

初始化数据库，我这里是16的版本，如果你是17或者更新的版本，把版本号改一下

/usr/lib/postgresql/16/bin/initdb -D /var/lib/postgresql/data

启动数据库，我这里是16的版本，如果你是17或者更新的版本，把版本号改一下

/usr/lib/postgresql/16/bin/pg_ctl -D /var/lib/postgresql/data -l logfile start

查看版本号

postgres@zookeeper-1:~$ psql -c "SELECT version();"
                                                              version
