# Install the repository RPM: sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm # Disable the built-in PostgreSQL module: sudo dnf -qy module disable postgresql # Install PostgreSQL: sudo dnf install -y postgresql13-server # Optionally initialize the database and enable automatic start: sudo /usr/pgsql-13/bin/postgresql-13-setup initdb sudo systemctl enable postgresql-13 sudo systemctl start postgresql-13
过程中如果出现错误，请执行：sudo dnf install wget
三、配置
# 切换成 postgres 用户 sudo -i -u postgres
\password
四、远程访问
cd /var/lib/pgsql/13/data
1、修改pg_hba.conf，添加一行到IPv4
host all all 0.0.0.0/0 scram-sha-256

取消#listen_addresses = ‘localhost‘注释
修改为listen_addresses = ‘*‘
3、重启
systemctl restart postgresql-13.service
