Redis 密码认证

2.2. /etc/redis.conf

2.2.1. 密码认证

打开 /etc/redis.conf 修改 requirepass 配置项

# vim /etc/redis.conf

requirepass test123

测试

# service redis restart
Stopping redis-server:                                     [  OK  ]
Starting redis-server:                                     [  OK  ]

# redis-cli
redis 127.0.0.1:6379> set h helloworld
(error) ERR operation not permitted

auth test123

redis 127.0.0.1:6379> auth test123
OK
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

redis-cli -a 参数指定密码

# redis-cli -a test123
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

通过 config 动态改变密码，无需重新启动 redis 进程

# redis-cli -a test123
redis 127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "test123"
redis 127.0.0.1:6379> config set requirepass passabc
OK
redis 127.0.0.1:6379> auth passabc
OK
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

注意：config 不能保存到配置文件

# grep requirepass /etc/redis.conf

# If the master is password protected (using the "requirepass" configuration
# requirepass foobared
requirepass test123

master/slave 模式， master 有密码, slave 怎样配置？

masterauth  password
