Modify operating mode

Redis is started in the foreground by default. Our actual development is to run as a daemon. Find daemonize no and modify it to yes

Modify the local area network to be accessible

Many times the redis we install will also be open to colleagues on other LANs to connect and modify

bind   成为  bind 

(If you specify a certain ip access, you can set the corresponding ip, pay attention to the production environment not to directly will allow all ip connections)

Enable redis key expiration push

In the common development process, we often need to use redis key expiration message notification, such as unpaid order expiration, activity time expiration, etc., find
