RMAN> exit

Recovery Manager complete.

Revisamos las variables de entorno

[oracle@vbgeneric oracle]$ env|grep SID
ORACLE_SID=orcl12c

Miramos si esta la variable NLS_DATE_FORMAT

[oracle@vbgeneric oracle]$ env|grep NSL

No obtenemos ningun resultado

[oracle@vbgeneric oracle]$ echo “export NLS_DATE_FORMAT=’DD-MM-RRRR HH24:MI:SS'” >> .bash_profile

Agregamos la variable al profile

[oracle@vbgeneric oracle]$ export NLS_DATE_FORMAT=’DD-MM-RRRR HH24:MI:SS’

Exportamos la variable y volvemos a acceder a RMAN

Ejecutar php sin servidor web

Hoy continuo realizando un proyecto, he tenido la necesidad de ver vía navegador parte de código antiguo que esta en php, pues bien, normalmente suelo ejecutar :

python -m SimpleHTTPServer 80

Serving HTTP on 0.0.0.0 port 80 ...
192.168.1.90 - - [08/Sep/2016 08:40:21] "GET / HTTP/1.1" 200 -
192.168.1.90 - - [08/Sep/2016 08:40:51] "GET /test HTTP/1.1" 200 -

Esto va muy bien si lo que necesitas ver es html o descargar algún fichero, normalmente lo utilizo para descargar algún pdf o música al móvil, entre otras.

El problema que surgía hoy es que tenia un antiguo proyecto en php, puedo arrancar alguna maquina virtual, subir el proyecto y listo, pero, por que no lo puedo visualizar desde mi equipo tal y como esta, la solución esta en php.

En mi caso como ejecutable php tengo el siguiente binario :

/usr/bin/php5

Este lo utilizo por consola para ejecutar algunos scripts en php.

Ahora bien, ¿como hago para poder poner en escucha el equipo en el puerto 80 y poder interpretar en código php?
Se hace de la siguiente forma:

Accedemos como superuser al directorio donde tenemos nuestro código php y ejecutamos:

php5 -S 127.0.0.1:80 -t .
php5 [options] -S <addr>:<port> [-t docroot]

Fuente: http://www.enmimaquinafunciona.com/pregunta/12982/como-ejecutar-php-con-simplehttpserver

Fuente: http://www.enmimaquinafunciona.com/pregunta/12982/como-ejecutar-php-con-simplehttpserver

Fuente: http://www.enmimaquinafunciona.com/pregunta/12982/como-ejecutar-php-con-simplehttpserver

Si os fijáis hay un punto al final, este indica el directorio actual, también podríamos indicar el directorio a publicar :

php5 -S 127.0.0.1:80 -t /home/test/project_php

De esta forma se pone a la escucha.

Listening on http://127.0.0.1:80
Document root is /home/test/project_php
Press Ctrl-C to quit.

Si accedemos vía navegador, veremos como se ejecuta correctamente:

También podemos observar a que fichero hemos accedido, con su código de estado:

Bien de una forma u otra podemos interpretar el código php para visualizarlo en el navegador, también recordemos como lo hemos hecho con python.
