一、查找redis.conf文件
我們服務器已經安裝了redis,現在通過命令查看下redis的進程:
[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
可以看到我們的redis-server的服務地址爲192.168.17.105,端口爲6379,對外訪問的時候需要指定對應的IP和端口:
redis-cli -h 192.168.17.105 -p 6379
查找redis安裝目錄
> whereis redis
redis: /usr/local/redis
我們可以看到redis在該目錄下安裝,然後找到配置文件redis.conf
> find /usr/local/redis/ -name redis.conf
/usr/local/redis/etc/redis.conf
修改配置文件:
vim redis.conf
改該配置文件即可:
requirepass foobared
requirepass 123 指定密碼123
最後一步,重新加載配置文件即可:
redis-server /usr/local/redis/etc/redis.conf
二、連接測試
通過密碼-a訪問:
> redis-cli -h 192.168.17.105 -p 6379 -a 123
運行結果:
```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
