PostgreSQL 12를 설치합니다.

yum install -y postgresql12.x86_64 postgresql12-contrib.x86_64 postgresql12-server.x86_64

데이터베이스를 초기화하다.

/usr/pgsql-12/bin/postgresql-12-setup initdb
Initializing database ... OK

데이터베이스를 시작합니다.

systemctl start postgresql-12

systemctl enable postgresql-12

postgreq 사용자의 비밀번호를 수정합니다.

-bash-4.2$ exit
  

데이터베이스 액세스 권한을 수정합니다.

vi /var/lib/pgsql/12/data/pg_hba.conf
......
# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only

# IPv4 local connections:

host    all              all             0.0.0.0/0               md5

데이터베이스에 원격으로 접근할 수 있도록 합니다.

vi /var/lib/pgsql/12/data/postgresql.conf
# - Connection Settings -

listen_addresses = '*'                  # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for all
                                        # (change requires restart)
port = 5432                             # (change requires restart)

systemctl restart postgresql-12
