PostgreSQL Overview

diposting pada tanggal 17 Agt 2016 02.36 oleh Putra Agung   [ diperbarui10 Feb 2017 06.14 ]

PostgreSQL has extensive and good help that should be the first source of information regarding this database product. This page outlines main differences to generic PostgreSQL installation used by Debian.

Installation

Required packages: postgresql postgresql-client

# apt-get install postgresql postgresql-client

Recommended packages:
  • postgresql-doc - PostgreSQL documentation.
  • pgadmin3 - PostgreSQL administration GUI.
  • phppgadmin - PostgreSQL web-based administration tool. 

Please note that the procedural languages are installed separately (plpgsql comes by default). Perform search packaging database to find the list of possibilities:

# aptitude search postgresql

User access

Both the default database user and default database are called postgres.

You may connect to the database using the following command:

# su - postgres
$ psql

New User and database

Create a regular system user account using adduser (skip this step to use an existing account):

# adduser mypguser    #from regular shell

Connect to database

# su - postgres
$ psql

Create a new database user and a database:

postgres=# CREATE USER mypguser WITH PASSWORD 'mypguserpass';
postgres=# CREATE DATABASE mypgdatabase OWNER mypguser;

or

# createuser mypguser    #from regular shell
# createdb -O mypguser mypgdatabase

Quit from the database

postgres=# \q

Connect as user mypguser to new database

# su - mypguser
$ psql mypgdatabase

or

# psql -d mypgdatabase -U mypguser

If you get errors like:

psql: FATAL:  Ident authentication failed for user "mypguser"

edit pg_hba.conf in /etc/postgresql/X.Y/main/pg_hba.conf

local   all         all                               trust     # replace ident or peer with trust

reload postgresql

# /etc/init.d/postgresql reload

Documentation

To get an overview about Debian's PostgreSQL architecture, instructions for a quick start, and pointers to the programs and manpages, have a look at /usr/share/doc/postgresql-common/README.Debian.gz.

Tutorial files

PostgreSQL documentation points to tutorial, which is included in postgresql-doc package. To get more information look at /usr/share/doc/postgresql-doc-[version]/tutorial/README.

Listing existing database clusters

Use pg_lsclusters command to check installed clusters and obtain some basic information such as: version (major version), name, port, status (online or down), owner, data directory and log file.

pg_lsclusters

pg_ctl replacement

pg_ctl is a PostgreSQL command line control program that can be used to control the database. Debian has made a Perl-wrapper for the pg_ctl called /usr/bin/pg_ctlcluster. Use the pg_ctlcluster whenever you need the pg_ctl. To customize the behavior check the /etc/postgresql/[version]/[cluster]/pg_ctl.conf

Debian installs SysV-init compatible (standard) start-up script /etc/init.d/postgresql-[version]. It can be used to start, stop, restart and reload the system. It calls pg_ctlcluster internally.

File locations

Debian splits the database configuration from the database files, opposed to generic PostgreSQL installation that puts everything under same directory. Note that Debian allows multiple clusters and even different versions of PostgreSQL to co-exist in same host.

Configuration files: /etc/postgresql/[version]/[cluster]/
Binaries: /usr/lib/postgresql/[version]
Data files: /var/lib/postgresql/[version]/[cluster]

Log files: Installing PostgreSQL creates log directory /var/log/postgresql/. Starting the database engine creates log file with name postgresql-[version]-[cluster].log.

Changing Debian default installation

Debian PostgreSQL installation automatically calls the initdb i.e. it initializes the cluster with default encoding and locale. Encoding can be changed later but the locale cannot. To change the locale (an possibly other options in initdb), delete the existing default cluster and create a new one:

1. Take root privileges.
2. Run the following command:

pg_dropcluster --stop <version> main

For example:
pg_dropcluster --stop 8.3 main

3. Run the initdb with your options. 

For example:
pg_createcluster --locale de_DE.UTF-8 --start 8.3 main


Warning!

The previous operation obviously deletes everything you had in cluster databases. Perform this operation right after you have installed the base package. Check the PostgreSQL manual if you need to change locale for an existing database (it is not a trivial operation).

Check the Locale page to see how to add more locales.

Automated Backup on Linux

diposting pada tanggal 17 Agt 2016 02.33 oleh Putra Agung   [ diperbarui10 Feb 2017 06.14 ]

Here are some scripts which will backup all databases in a cluster individually, optionally only backing up the schema for a set list. The reason one might wish to use this over pg_dumpall is that you may only wish to restore individual databases from a backup, whereas pg_dumpall dumps a plain SQL copy into a single file. This also provides the option of specifying which databases you only want the schema of. The idea is to run these in a nightly cron job.

  • pg_backup.config - The main configuration file. This should be the only file which needs user modifications.
  • pg_backup.sh - The normal backup script which will go through each database and save a gzipped and/or a custom format copy of the backup into a date-based directory.
  • pg_backup_rotated.sh - The same as above except it will delete expired backups based on the configuration. 


Using Rsync

diposting pada tanggal 15 Agt 2016 10.25 oleh Putra Agung   [ diperbarui17 Agt 2016 02.31 ]

Introduction

Rsync, which stands for "remote sync", is a remote and local file synchronization tool. It uses an algorithm that minimizes the amount of data copied by only moving the portions of files that have changed.

In this guide, we will cover the basic usage of this powerful utility. We will be using an Ubuntu 12.04 VPS in the examples, but you can use any modern Linux distribution to follow along.

What Is Rsync?

Rsync is a very flexible network-enabled syncing tool. It can also refer to the network protocol developed to utilize this tool.

When we reference rsync in this guide, we are mainly referring to the utility, and not the protocol.

Due to its ubiquity on Linux and Unix-like systems and its popularity as a tool for system scripts, it is included on most Linux distributions by default.

Basic Syntax

The basic syntax of rsync is very straight forward, and operates in a way that is similar to ssh, scp, and cp.

We will create two test directories and some test files with the following commands:

cd ~
mkdir dir1
mkdir dir2
touch dir1/file{1..100}

We now have a directory called dir1 with 100 empty files in it.

ls dir1
file1    file18  file27  file36  file45  file54  file63  file72  file81  file90
file10   file19  file28  file37  file46  file55  file64  file73  file82  file91
file100  file2   file29  file38  file47  file56  file65  file74  file83  file92
file11   file20  file3   file39  file48  file57  file66  file75  file84  file93
file12   file21  file30  file4   file49  file58  file67  file76  file85  file94
file13   file22  file31  file40  file5   file59  file68  file77  file86  file95
file14   file23  file32  file41  file50  file6   file69  file78  file87  file96
file15   file24  file33  file42  file51  file60  file7   file79  file88  file97
file16   file25  file34  file43  file52  file61  file70  file8   file89  file98
file17   file26  file35  file44  file53  file62  file71  file80  file9   file99

We also have an empty directory called dir2.

To sync the contents of dir1 to dir2 on the same system, type:

rsync -r dir1/ dir2

The -r option means recursive, which is necessary for directory syncing.

We could also use the -a flag instead:

rsync -a dir1/ dir2

The -a option is a combination flag.

It stands for "archive" and syncs recursively and preserves symbolic links, special and device files, modification times, group, owner, and permissions.

It is more commonly used than -r and is usually what you want to use.

An Important Note

You may have noticed that there is a trailing slash (/) at the end of the first argument in the above commands:

rsync -a dir1/ dir2

This is necessary to mean "the contents of dir1".

The alternative, without the trailing slash, would place dir1, including the directory, within dir2. This would create a hierarchy that looks like:

~/dir2/dir1/[files]

Always double-check your arguments before executing an rsync command.

Rsync provides a method for doing this by passing the -n or --dry-run options. The -v flag (for verbose) is also necessary to get the appropriate output:

rsync -anv dir1/ dir2
sending incremental file list
./
file1
file10
file100
file11
file12
file13
file14
file15
file16
file17
file18
. . .

Compare this output to the output we get when we remove the trailing slash:

rsync -anv dir1 dir2
sending incremental file list
dir1/
dir1/file1
dir1/file10
dir1/file100
dir1/file11
dir1/file12
dir1/file13
dir1/file14
dir1/file15
dir1/file16
dir1/file17
dir1/file18
. . .

You can see here that the directory itself is transfered.

How To Use Rsync to Sync with a Remote System

Syncing to a remote system is trivial if you have SSH access to the remote machine and rsync installed on both sides. If you need to set up SSH keys, click here.

Once you have SSH access verified on between the two machines, you can sync the dir1 folder from earlier to a remote computer by using this syntax (note that we want to transfer the actual directory in this case, so we omit the trailing slash):

rsync -a ~/dir1 username@remote_host:destination_directory

This is called a "push" operation because it pushes a directory from the local system to a remote system.

The opposite operation is "pull". It is used to sync a remote directory to the local system. If the dir1 were on the remote system instead of our local system, the syntax would be:

rsync -a username@remote_host:/home/username/dir1 place_to_sync_on_local_machine

Like "cp" and similar tools, the source is always the first argument, and the destination is always the second.

Useful Options for Rsync

Rsync provides many options for altering the default behavior of the utility. We have already discussed some of the more necessary flags.

If you are transferring files that have not already been compressed, like text files, you can reduce the network transfer by adding compression with the -z option:

rsync -az source destination

The -P flag is very helpful. It combines the flags --progress and --partial. The first of these gives you a progress bar for the transfers and the second allows you to resume interrupted transfers:

rsync -azP source destination
sending incremental file list
./
file1
           0 100%    0.00kB/s    0:00:00 (xfer#1, to-check=99/101)
file10
           0 100%    0.00kB/s    0:00:00 (xfer#2, to-check=98/101)
file100
           0 100%    0.00kB/s    0:00:00 (xfer#3, to-check=97/101)
file11
           0 100%    0.00kB/s    0:00:00 (xfer#4, to-check=96/101)
. . .

If we run the command again, we will get a shorter output, because no changes have been made.

This illustrates rsync's ability to use modification times to determine if changes have been made.

rsync -azP source destination
sending incremental file list

sent 818 bytes received 12 bytes 1660.00 bytes/sec
total size is 0 speedup is 0.00

We can update the modification time on some of the files and see that rsync intelligently re-copies only the changed files:

touch dir1/file{1..10}
rsync -azP source destination
sending incremental file list
file1
           0 100%    0.00kB/s    0:00:00 (xfer#1, to-check=99/101)
file10
           0 100%    0.00kB/s    0:00:00 (xfer#2, to-check=98/101)
file2
           0 100%    0.00kB/s    0:00:00 (xfer#3, to-check=87/101)
file3
           0 100%    0.00kB/s    0:00:00 (xfer#4, to-check=76/101)
. . .

In order to keep two directories truly in sync, it is necessary to delete files from the destination directory if they are removed from the source. By default, rsync does not delete anything from the destination directory.

We can change this behavior with the --delete option. Before using this option, use the --dry-run option and do testing to prevent data loss:

rsync -a --delete source destination

If you wish to exclude certain files or directories located inside a directory you are syncing, you can do so by specifying them in a comma-separated list following the --exclude= option:

rsync -a --exclude=pattern_to_exclude source destination

If we have specified a pattern to exclude, we can override that exclusion for files that match a different pattern by using the --include= option.

rsync -a --exclude=pattern_to_exclude --include=pattern_to_include source destination

Conclusion

Rsync can simplify file transfers over networked connections and add robustness to local directory syncing. The flexibility of rsync makes it a good option for many different file-level operations.

A mastery of rsync allows you to design complex backup operations and obtain fine-grained control over what is transferred and how.
