Redis was installed on the server today. For security reasons, set the password to access redis-server.

1. Find the redis.conf file

Our server has installed redis, now check the redis process through the command:

[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

You can see our The service address of redis-server is 192.168.17.105, and the port is 6379. When accessing externally, you need to specify the corresponding IP and port:

redis-cli -h 192.168.17.105 -p 6379

Search redis installation directory

> whereis redis
redis: /usr/local/redis

We can see that redis is installed in this directory, and then find the configuration fileredis.conf

> find /usr/local/redis/ -name redis.conf
/usr/local/redis/etc/redis.conf

Modify the configuration file:

vim redis.conf

Just change the configuration file:

# requirepass foobared
requirepass 123   指定密码123

The last step is to reload the configuration file:

 redis-server /usr/local/redis/etc/redis.conf

2. Connection test

Pass password -aAccess:

> redis-cli -h 192.168.17.105 -p 6379 -a 123

Run result:

[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
