Redirecting to /bin/systemctl start redis.service

三、配置

1、redis配置文件默认路径

/etc/redis.conf

2、修改配置文件

[root@iZuf61gy3n1d12woog919aZ html]# vim /etc/redis.conf
################################# GENERAL #####################################
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# 如果需要在其它地方远程redis，需要注释下面的一行
bind 127.0.0.1
# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
# 启动守护进程
daemonize yes
...

3、设置密码

// 进入redis命令行
[root@iZuf61gy3n1d12woog919aZ html]# /usr/bin/redis-cli -p 6379
// 修改密码为123456
127.0.0.1:6379> config set requirepass 123456
127.0.0.1:6379> ok
// 需要使用密码重新进入redis
[root@iZuf61gy3n1d12woog919aZ html]# /usr/bin/redis-cli -p 6379 -a 123456
// 查询密码
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "123456"
