![]() Prior to installing an ODBC driver on Linux, you need to install the unixODBC driver manager and its dependencies. Both DEB and RPM packages of Devart ODBC drivers require unixODBC as the driver manager. You can choose to install the ODBC driver using the DEB or RPM package, depending on your Linux distribution. If you would like to use iODBC with our drivers on Linux, you would have to manually modify the configuration files of the driver manager note though that full compatibility with iODBC and stable operation of the drivers is not guaranteed in this event. We recommend using the unixODBC driver manager as it is more popular among Linux users and our drivers are fully compatible with it. On Linux systems, you can choose between the unixODBC and iODBC driver manager. The driver manager carries out a number of tasks, such as resolving data source names, loading and unloading of the driver, processing and passing ODBC function calls to the driver, mapping function calls and data types between different versions of the ODBC standard, e.g. ODBC drivers work under the control of an ODBC driver manager, which is a library that manages communication between the ODBC-aware application and ODBC drivers. It allows an ODBC-compliant application to gain access to one or more data sources. ![]() It is based on call-level specifications for database APIs and uses SQL as its database access language.Īn ODBC driver uses the ODBC interface to access data in database management systems. Open Database Connectivity (ODBC) is an industry-standard application programming interface for database access. Step-By-Step ODBC Data Source Setup on Linux.Installing and Configuring an ODBC Driver on CentOS.Installing and Configuring an ODBC Driver on Ubuntu.If your permissions scheme is currently ‘Ident’ you might need to change that to ‘md5’ as PhpPgAdmin requires it.This article explains how to install, configure, and test Devart ODBC drivers on Debian-based or RPM-based Linux distributions. PostgreSQL visual interface similar to phpMyAdmin? – in short, if you know phpMyAdmin and want phpPgAdmin, you need to add the EPEL repositories, Apache (yum install httpd) and then install using: # su postgres -c psql Add (or create) a user with permission to specific database? # You can also short the two commands into: # CTRL + D twice to exit both psql and su. To start ‘psql’ as postgres: # change user to postgres Managing from Command line login to postgresĪs I mentioned, default setup has ident authentication means the only user that can get in initially is user “postgres”, so if you haven’t changed permissions scheme you should su to postgres before. read the PostgreSQL: Documentation: Getting Started to configure your environment. ![]() To make centos postgresql load on boot use the chkconfig command as follows: chkconfig postgresql on #listen_addresses = 'localhost'Īnd then, to start on centos postgresql service use: service postgresql start If you need to change the default port (5432 by default) and Listen Addresses (localhost by default), you can set those vars inside the nf inside /var/lib/pgsql/data folder. If you want to use phpPgAdmin (described later) you should change from ‘Ident’ to ‘md5’ or else it won’t login to your system. change from ‘ident’ to ‘md5’ is recommended. If you want to login and use postgres with other users than `postgres` you can change the permissions method in pg_hba.conf. Psql: FATAL: Ident authentication failed for user “root” Means the only user that can get in initially is user “postgres”, so if you’ll try ‘psql’ from root you’ll get error: These configuration settings are in the pg_hba.conf file inside the data folder. You can’t run this command again without deleting first this folder (and all your data).Īlso, when you called the initdb command above from RedHat’s init script configured permissions on the database. This created a data folder in /var/lib/pgsql. To init on centos postgresql service use: service postgresql initdb If you’ll try to start PostgreSQL using the service command, you will see an error tells you must init the db first and create the db files in: /var/lib//pgsql/data If you prefer or installed using repository (yum), continue… If you want to compile using source you better move to that article. it’s recommended for advanced users and one may argue it’s recommended too for production.Īnyway, this article from DigitalOcean covers this area well (and more). ![]() If you want to install the latest version of PostgreSQL you should compile from source. ![]()
