SpringBoot3集成PostgreSQL的详细过程

# 1、RPM仓库
sudo yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
# 2、安装PostgreSQL
sudo yum install -y postgresql14-server
# 3、初始化选项
sudo /usr/pgsql-14/bin/postgresql-14-setup initdb
sudo systemctl enable postgresql-14
sudo systemctl start postgresql-14
# 4、查看版本
psql --version
psql (PostgreSQL) 14.11
