PostgreSQL is a popular open-source relational database management system (RDBMS). It is available in both binary and source code distributions. This article will show you how to install PostgreSQL from source on a Linux system.
Prerequisites
Before you can install PostgreSQL from source, you will need to have the following prerequisites installed on your system:
- A Linux distribution, such as Ubuntu, Fedora, or CentOS
- A compiler, such as GCC or Clang
- A development library, such as GNU Development Tools (GDT) or LLVM
- A text editor, such as Vim or Emacs
Installing PostgreSQL from Source
To install PostgreSQL from source, follow these steps:
- Download the PostgreSQL source code from the PostgreSQL website.
- Extract the PostgreSQL source code archive.
- Change to the PostgreSQL source code directory.
- Run the
./configure
script to configure PostgreSQL for your system. - Run the
make
command to build PostgreSQL. - Run the
make install
command to install PostgreSQL on your system.
Configuring PostgreSQL
The ./configure
script allows you to configure PostgreSQL for your system. The following are some of the options that you can configure:
- The data directory: This is the directory where PostgreSQL will store its data files.
- The port number: This is the port number that PostgreSQL will listen on.
- The user name and password for the PostgreSQL superuser: The PostgreSQL superuser is a special user that has complete control over the PostgreSQL database cluster.
Building PostgreSQL
The make
command builds PostgreSQL from source. This may take a few minutes to complete.
Installing PostgreSQL
The make install
command installs PostgreSQL on your system. This will create a number of files and directories, including:
- The PostgreSQL binaries: These are the executable files that you will use to interact with PostgreSQL.
- The PostgreSQL libraries: These are the libraries that are used by the PostgreSQL binaries.
- The PostgreSQL documentation: This is the documentation for PostgreSQL.
Starting PostgreSQL
To start PostgreSQL, run the following command:
pg_ctl start
This will start the PostgreSQL server. You can then connect to PostgreSQL using a client application, such as psql.
Stopping PostgreSQL
To stop PostgreSQL, run the following command:
pg_ctl stop
This will stop the PostgreSQL server.
Restarting PostgreSQL
To restart PostgreSQL, run the following command:
pg_ctl restart
This will stop and then start the PostgreSQL server.
Backing Up PostgreSQL
To back up PostgreSQL, run the following command:
pg_dumpall > backup.sql
This will create a SQL dump of the PostgreSQL database cluster. You can then use this SQL dump to restore PostgreSQL to a different system.
Restoring PostgreSQL
To restore PostgreSQL from a backup, run the following command:
psql -U postgres -d postgres -f backup.sql
This will restore the PostgreSQL database cluster from the SQL dump.
