1. 安装并对redis进行配置
更新源并安装redis
sudo apt-get update
sudo apt-get install redis-server
将redis设置为systemctl
sudo vim /etc/redis/redis.conf
找到supervised选项，设置为systemd
# If you run Redis from upstart or systemd, Redis can interact with your
# supervision tree. Options:
# supervised no - no supervision interaction
# supervised upstart - signal upstart by putting Redis into SIGSTOP mode
# supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
# supervised auto - detect upstart or systemd method based on
# UPSTART_JOB or NOTIFY_SOCKET environment variables
# Note: these supervision methods only signal "process is ready."
# They do not enable continuous liveness pings back to your supervisor.
supervised systemd
开启redis服务
sudo service redis-server start
2. 测试redis
查看redis运行状态
sudo service redis-server status
打开redis命令行
redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set test "It's a working"
OK
127.0.0.1:6379> get test
"It's a working"
127.0.0.1:6379>exit
退出后重新连接redis，再次访问test键
127.0.0.1:6379> get test
"It's a working"
127.0.0.1:6379>
3. 绑定到本地
一般来说，不推荐配置redis远程可访问，因此，这里只将其配置为本地可访问。
打开Redis configuration file
sudo vim /etc/redis/redis.conf
定位到bind,并将其配置如下
# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
bind 127.0.0.1 ::1 # 这里本来被注释掉，去掉注释即可
保存退出，重启redis
sudo service redis-server restart
查看此项配置是否生效
$ sudo netstat -lnp | grep redis
tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 2086/redis-server 1
tcp6 0 0 ::1:6379 :::* LISTEN 2086/redis-server 1
4. 为redis配置密码
打开redis配置文件，定位到# requirepass foobared
sudo vim /etc/redis/redis.conf
将# requirepass foobared注释去掉，把foobared改成你想要的密码。
重启redis服务
sudo service redis-server restart
再次进入redis，尝试get
$ redis-cli
127.0.0.1:6379> get test
(error) NOAUTH Authentication required.
127.0.0.1:6379>
get失败，因为没有进行认证.
127.0.0.1:6379> auth your_redis_password
OK
127.0.0.1:6379> get test
"It's a working"
127.0.0.1:6379>
