explica como configurar las Variables de Entorno en Linux.<\/p>\r\n<p>Informaci\u00f3n extra\u00edda de:<br \/><a href=\"https:\/\/www.sysadmit.com\/2016\/04\/linux-variables-de-entorno-permanentes.html\">https:\/\/www.sysadmit.com\/2016\/04\/linux-variables-de-entorno-permanentes.html<\/a><\/p>\r\n<p>&nbsp;<\/p>\r\n<p>En sistemas Linux podemos ver, crear y modificar variables de entorno.<\/p>\r\n<p>Por defecto, cuando creamos, modificamos o borramos variables de entorno del sistema, al reiniciar se pierden los cambios efectuados.<\/p>\r\n<p>Veamos como administrar las variables de entorno en Linux:<\/p>\r\n<p>Ejecutando los comandos:\u00a0printenv,\u00a0env\u00a0o\u00a0set, podemos ver las variables de entorno actuales.<\/p>\r\n<p>Para ver una variable de entorno espec\u00edfica deberemos utilizar\u00a0printenv, por ejemplo:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>printenv USER<\/strong><br \/>root<\/p>\r\n<p>Para crear una variable de entorno, utilizaremos el comando\u00a0export:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>export VARIABLEENTORNO=SYSADMIT<\/strong><\/p>\r\n<p>Resultado:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>printenv | grep VARIABLEENTORNO<br \/><\/strong>VARIABLEENTORNO=SYSADMIT<\/p>\r\n<p>o bien:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>echo $VARIABLEENTORNO<\/strong><br \/>SYSADMIT<\/p>\r\n<p>Si quisi\u00e9ramos eliminar la variable de entorno, bastar\u00eda con ejecutar:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>export VARIABLEENTORNO=<\/strong><\/p>\r\n<p>Resultado:<\/p>\r\n<p>[root@LINUX1 ~]#\u00a0<strong>echo $VARIABLEENTORNO<\/strong><\/p>\r\n<p><strong>\u00bfC\u00f3mo configuramos una variable de entorno permanente?<\/strong><\/p>\r\n<p>Tendremos que configurar el\u00a0export\u00a0que establece la variable de entorno al inicio, editando alguno de los scripts de inicio que se ejecutan de forma predeterminada.<\/p>\r\n<p>Para ello, disponemos de los siguientes scripts que se cargan al inicio:<\/p>\r\n<p>Para todos los usuarios:\u00a0<\/p>\r\n<p>\/etc\/profile<\/p>\r\n<p>Para un usuario espec\u00edfico:<\/p>\r\n<p>\u00a0~\/.bash_profile<\/p>\r\n<p>~\/.bash_login<\/p>\r\n<p>~\/.profile<\/p>\r\n<p>El orden de carga de los scripts de inicio es el indicado, es decir primero se ejecuta:\u00a0\/etc\/profile\u00a0y luego al hacer login, por este orden:\u00a0\u00a0~\/.bash_profile, ~\/.bash_login, ~\/.profile<\/p>\r\n<p>~\/\u00a0:\u00a0Se refiere al home directory del usuario, por ejemplo, para el usuario root:\u00a0\u00a0~\/\u00a0equivale a\u00a0\/root\/<\/p>\r\n<p>Tambi\u00e9n podemos ver como los scripts de usuario, tienen un punto al principio del nombre del fichero, por lo tanto son ficheros ocultos.<\/p>\r\n<p>Podemos ver las variables de entorno permanentes que se inicializan en\u00a0\/etc\/profile, ejecutando:<\/p>\r\n<p>cat \/etc\/profile|grep export<\/p>\r\n<p><br \/><strong>Best practice:<\/strong><br \/><br \/>Si encontramos el fichero:\u00a0\/etc\/environment\u00a0en nuestro sistema operativo Linux,\u00a0ser\u00e1 el sitio donde ubicar las variables de entorno\u00a0permanentes.<br \/><br \/>Tengamos en cuenta que las reglas aqu\u00ed configuradas se ejecutar\u00e1n para todos los usuarios.<br \/><br \/>Ejemplo:<br \/><br \/>[root@LINUX1 ~]#\u00a0<strong>ls -lF \/etc\/environment<\/strong><br \/>-rw-r&#8211;r&#8211;. 1 root root 0 Oct 29\u00a0 2014 \/etc\/environment<br \/><br \/>En este ejemplo, podemos ver como existe el fichero\u00a0\/etc\/environment\u00a0y ocupa 0 bytes, pero al existir, significa que el sistema lo\u00a0procesar\u00e1 al inicio, por lo tanto si lo editamos y situamos\u00a0las variables de entorno all\u00ed, ser\u00e1n procesadas.<br \/><br \/>Esta es la forma m\u00e1s limpia de\u00a0configurar nuestras variables de entorno permanentes a nivel de equipo, ya que la definici\u00f3n de las mismas quedar\u00e1 separada del resto de configuraci\u00f3n definida en\u00a0los\u00a0scripts\u00a0de inicio.<br \/><br \/>El formato del interior de\u00a0\/etc\/environment\u00a0para definir las variables de entorno permanentes es el siguiente:<br \/><br \/>VARIABLEENTORNO=SYSADMIT<\/p>\r\n<p>&nbsp;<\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>En esta entrada se explica como
