General Options: -h, --help Show help. --isolated Run pip in an isolated mode, ignoring environment variables and user configuration. -v, --verbose Give more output. Option is additive, and can be used up to 3 times. -V, --version Show version and exit. -q, --quiet Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels). --log <path> Path to a verbose appending log. --proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port. --retries <retries> Maximum number of retries each connection should attempt (default 5 times). --timeout <sec> Set the socket timeout (default 15 seconds). --exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort. --trusted-host <hostname> Mark this host as trusted, even though it does not have valid or any HTTPS. --cert <path> Path to alternate CA bundle. --client-cert <path> Path to SSL client certificate, a single file containing the private key and the certificate in PEM format. --cache-dir <dir> Store the cache data in <dir>. --no-cache-dir Disable the cache. --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download.

Editamos un archivo de prueba python (testpython.py)
import redis #crear una connexion con la instancia del servidor local de redis# por default corren en puerto 6379redis_db = redis.StrictRedis(host="localhost", port=6379, db=0) redis_db.keys() redis_db.set("redis","Esta funcionando!") redis_db.keys() redis_db.get("redis") redis_db.incr("visitas") redis_db.get("visitas")
Este programa incrementa la key visitas, ahora jugamos con redis-cli para colocar la key visitas a un valor de 1.
