一、查找redis.conf文件
我们服务器已经安装了redis,现在通过命令查看下redis的进程:
[root@lnp ~]# ps -aux|grep redis
root 7374 0.0 0.0 145312 7524 ? Ssl 16:37 0:00 redis-server 192.168.17.105:6379
root 10692 0.0 0.0 112724 984 pts/7 S+ 16:54 0:00 grep --color=auto redis
可以看到我们的redis-server的服务地址为192.168.17.105,端口为6379,对外访问的时候需要指定对应的IP和端口:
redis-cli -h 192.168.17.105 -p 6379
查找redis安装目录
> whereis redis
redis: /usr/local/redis
我们可以看到redis在该目录下安装,然后找到配置文件redis.conf
> find /usr/local/redis/ -name redis.conf
/usr/local/redis/etc/redis.conf
修改配置文件:
vim redis.conf
改该配置文件即可:
requirepass 123 指定密码123
最后一步,重新加载配置文件即可:
redis-server /usr/local/redis/etc/redis.conf
二、连接测试
通过密码-a访问:
> redis-cli -h 192.168.17.105 -p 6379 -a 123
运行结果:
```c
[root@lnp etc]# redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit
[root@lnp etc]# redis-cli -h 192.168.17.105 -p 6379

192.168.17.105:6379> exit
[root@lnp etc]# redis-cli -h 192.168.17.105 -p 6379 -a 123
