Postgres CentOS

Install PostgreSql Server

Login as the root user and enter the command:
# yum install postgresql postgresql-server

Start Postgresql

Type the following two command:
# chkconfig postgresql on
# service postgresql start

Connect to Postgresql Server

Connect to server using
# su - postgres

Connect using psql command line tool:
$ psql -d template1 -U postgres

Open TCP port 5432

Finally make sure iptables allows remote access to Postgresql database server:
Open /etc/sysconfig/iptables file:
# vi /etc/sysconfig/iptables
Append following line before COMMIT line to open port 5432:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5432 -j ACCEPT

Save and close the file. Restart the firewall:
# service iptables restart

wget http://yum.pgsqlrpms.org/reporpms/8.4/pgdg-centos-8.4-2.noarch.rpm
rpm -Uhv pgdg-centos-8.4-2.noarch.rpm
if don't work see url: http://yum.pgsqlrpms.org/reporpms/8.4

Adds
======
#su postgres
psql -d template1 -U postgres (enter the template1 service database)
alter user postgres with password 'postgres_password'; (run query to change the password)
/sbin/service postgresql restart

nmap -P0 -p 5432 192.168.1.2 (if don't have nmap --> #yum install nmap)
Here are the important lines from pg_hba.conf:
Some where you will have a file called postgresql.conf
#listen_addresses = 'localhost' --> '*' and uncomment

NHibernate works without mapping

ISQLQuery query = Session.CreateSQLQuery("SELECT p.*, c.* FROM Product p Left JOIN Product_CustomField c on p.ProductId=c.ProductId");
query.SetResultTransformer(NHibernate.Transform.Transformers.AliasToBean(typeof(Product)));
IList resultList = query.List();

Notes:
Add CusTomField1..5 into Product Class,not need declared in .hbm.xml

Combine with ScalarFields
public class SqlRepository {
...
public IList ListEmployees() {
using (ISession session = _sessionBuilder.GetSession()) {
return session
.CreateSQLQuery(@"
SELECT No_ AS EmployeeNumber, [E-mail Login] AS Username
FROM Employees")
.AddScalar("EmployeeNumber", NHibernateUtil.String)
.AddScalar("Username", NHibernateUtil.String)
.SetResultTransformer(Transformers.AliasToBean())
.List();
}
}
}


Add nHibernate mapping at run time
ISessionFactory sf = new Configuration()
.AddFile("Product.hbm.xml")
.AddFile("Category.hbm.xml")

Postgres configuration

classical paths

# vi /var/lib/pgsql/data/postgresql.conf
# vi /opt/Postgres/8.4/data/postgresql.conf


Enable Network:

listen_addresses = 'localhost' to listen_addresses = '*'

You must also have appropriate entries in pg_hba.conf for hosts and
authentication type. You could use something like:

#TYPE DATABASE USER ADDRESS METHOD
local all all password
host all all 127.0.0.1/32 password
host all all 192.168.1.0/24 password

Next line allow all ips
host all all 0.0.0.0/0 md5

Postgres save images

CREATE TABLE images (name text, img bytea);

 File file = new File("image.gif");
 FileInputStream fis = new FileInputStream(file);
 PreparedStatement ps = conn.prepareStatement("INSERT INTO images VALUES (?, ?)");
 ps.setString(1, file.getName());
 ps.setBinaryStream(2, fis, file.length());
 ps.executeUpdate();
 ps.close();
 fis.close();

setBinaryStream(), transfers a set number of bytes from a stream.
setBytes(), use this method if the contents of the image was already in a byte[].

Retrieving image

  PreparedStatement ps = conn.prepareStatement("SELECT img FROM images WHERE name=?");
  ps.setString(1, "image.gif");
  ResultSet rs = ps.executeQuery();
  if(rs.next()) {
         byte[] imgBytes = rs.getBytes(1);
  }
  rs.close();
 }
 ps.close();

You could have used a InputStream object instead.

Alternatively you could be storing a very large file and want to use the LargeObject API to store the file:

CREATE TABLE imagesLO (imgname text, imgOID OID);

To insert an image, you would use:

 conn.setAutoCommit(false); // All LargeObject API calls must be within a transaction
 
 LargeObjectManager lobj = ((org.postgresql.PGConnection)conn).getLargeObjectAPI();
 
 //create a new large object
 int oid = lobj.create(LargeObjectManager.READ | LargeObjectManager.WRITE);
 
 //open the large object for write
 LargeObject obj = lobj.open(oid, LargeObjectManager.WRITE);
 
 // Now open the file
 File file = new File("image.gif");
 FileInputStream fis = new FileInputStream(file);
 
 // copy the data from the file to the large object
 byte buf[] = new byte[2048];
 int s, tl = 0;
 while ((s = fis.read(buf, 0, 2048)) > 0)
 {
 obj.write(buf, 0, s);
 tl += s;
 }
 
 obj.close();
 
 //Now insert the row into imagesLO
 PreparedStatement ps = conn.prepareStatement("INSERT INTO imagesLO VALUES (?, ?)");
 ps.setString(1, file.getName());
 ps.setInt(2, oid);
 ps.executeUpdate();
 ps.close();
 fis.close();

Retrieving the image from the Large Object:

 conn.setAutoCommit(false);
 
 // Get the Large Object Manager to perform operations with
 LargeObjectManager lobj = ((org.postgresql.PGConnection)conn).getLargeObjectAPI();
 
 PreparedStatement ps = con.prepareStatement("SELECT imgOID FROM imagesLO WHERE imgname=?");
 ps.setString(1, "image.gif");
 ResultSet rs = ps.executeQuery();
 if (rs.next()) 
 {
  int oid = rs.getInt(1);//open the large object for reading
 LargeObject obj = lobj.open(oid, LargeObjectManager.READ);
 
 //read the data
 byte buf[] = new byte[obj.size()];
 obj.read(buf, 0, obj.size());
 //do something with the data read here
 obj.close();
 }
     rs.close();
 }
 ps.close();
