10. 登录测试¶
redis-cli
set num 10
get num
[root@152 redis]# redis-cli
127.0.0.1:6379> set num 10
OK
127.0.0.1:6379> get num
"10"
127.0.0.1:6379> exit
[root@152 redis]#
redis-cli基本功能¶
1. 进入命令行¶
redis-cli
2. 退出命令行¶
exit
3. 退出redis¶
redis-cli
shutdown
#或者
redis-cli shutdown
4. 启动redis¶
redis-server /data/6379/redis.conf
5. 登录本地redis¶
redis-cli -p 6379
6. 登录远程redis¶
#刚安装的redis有安全策略，不可远程登录
redis-cli -h 192.168.178.152 -p 6379
[root@152 redis]# redis-cli -h 192.168.178.152 -p 6379

(error) DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

7. 非交互式命令¶
redis-cli set num 10
8. 批量执行redis命令¶
#1.创建redis命令文件
vim /tmp/1.txt
set a 1
set b 2
set c 3
#2.批量执行
cat /tmp/1.txt |redis-cli
[root@152 redis]# vim /tmp/1.txt
[root@152 redis]# cat /tmp/1.txt
set a 1
set b 2
set c 3
[root@152 redis]# cat /tmp/1.txt |redis-cli
OK
OK
OK
[root@152 redis]# redis-cli get a
"1"
[root@152 redis]# redis-cli get b
"2"
[root@152 redis]# redis-cli get c
"3"
9. redis-cli命令参数¶
redis-cli
-p：指定端口
-h：指定IP
-a：指定密码
redis安全管理¶
1. 介绍¶
#redis默认开启了保护模式，只允许本地回环地址登录并访问数据库
2. 参数¶
protected-mode yes/no #保护模式，是否只允许本地访问
3. bind：指定IP监听(即白名单)¶
vim /data/6379/redis.conf
#添加如下一行内容
bind 192.168.178.152 127.0.0.1
4. 设置密码¶
vim /data/6379/redis.conf
requirepass 123456
5. 如何使用密码¶
#方法1:命令行中输入密码
redis-cli -a 123456
#方法2：客户端中输入密码
redis-cli
auth 123456
[root@152 redis]# vim /data/6379/redis.conf
[root@152 redis]# redis-cli shutdown
[root@152 redis]# redis-server /data/6379/redis.conf
[root@152 redis]#
[root@152 redis]# redis-cli
127.0.0.1:6379> set d 1
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> set d 1
OK
127.0.0.1:6379> get d
"1"
127.0.0.1:6379> quit
[root@152 redis]# redis-cli -a 123456
127.0.0.1:6379> set e 2
OK
127.0.0.1:6379> get e
