參考：https://www.postgresql.org/download/linux/redhat/

 

• Install the repository RPM:yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-centos10-10-1.noarch.rpm
• Install the client packages:yum install postgresql10
• Optionally install the server packages:yum install postgresql10-server
• Optionally initialize the database and enable automatic start:
• /usr/pgsql-10/bin/postgresql-10-setup initdb
systemctl enable postgresql-10
systemctl start postgresql-10

修改密碼：

su postgres
psql
ALTER USER postgres WITH PASSWORD '123456';
\q
su root

修改PostgresSQL數據庫配置實現遠程訪問

①、修改postgresql.conf 文件：

vi /var/lib/pgsql/10/data/postgresql.conf

 

將listen_addresses前的#去掉，並將 listen_addresses = 'localhost' 改爲 listen_addresses = '*'； 
②、修改客戶端認證配置文件pg_hba.conf，將須要遠程訪問數據庫的IP地址或地址段加入該文件。

vi /var/lib/pgsql/10/data/pg_hba.conf

 

將IPv4區下的127.0.0.1/32修改成0.0.0.0/0； 將ident修改成md5 
③、重啓服務使設置生效

systemctl restart postgresql-10
