2.Ubuntu Installing Redis
I have a lot of problems when installing RESID, actually did not solve, just changed the way of installation, which has insufficient permissions, the reason is not logged in as root, the installation steps:
Installing Redis
sudo apt-get update
sudo apt-get install Redis-server
Start Redis
Redis-server
Connecting from a client
Redis-cli
Http://www.cnblogs.com/taceywong/p/5840163.html contains an explanation of the REDIS-CLI parameters
To see if the boot was successful (the previous step goes to the terminal, which is equivalent to installing MySQL, after entering MySQL)
Ping
(If Pong appears, the installation is successful)
