打开 /etc/redis.conf 修改 requirepass 配置项

# vim /etc/redis.confrequirepass test123

测试

# service redis restartStopping redis-server:                                     [  OK  ]Starting redis-server:                                     [  OK  ]# redis-cliredis 127.0.0.1:6379> set h helloworld(error) ERR operation not permitted

auth test123

redis 127.0.0.1:6379> auth test123OKredis 127.0.0.1:6379> set h helloworldOKredis 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 test123redis 127.0.0.1:6379> set h helloworldOKredis 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 test123redis 127.0.0.1:6379> config get requirepass1) "requirepass"2) "test123"redis 127.0.0.1:6379> config set requirepass passabcOKredis 127.0.0.1:6379> auth passabcOKredis 127.0.0.1:6379> set h helloworldOKredis 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 foobaredrequirepass test123

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

masterauth  password
