redis设置允许远程连接

打开redis配置文件 /usr/local/redis/etc/redis.conf

（1）设置后台启动

将redis.conf配置文件中daemonize no 改成 yes

daemonize yes

（2）设置远程连接

将redis.conf配置文件中里面的bind 那一行注释掉

#bind 127.0.0.1 -::1

（3）关闭保护模式

protected-mode no

（4）设置密码

requirepass 密码

（5）以阿里云为例，到控制平台，安全组添加6379端口

（6）防火墙开放端口

注：未开启防火墙可省略这一步骤

#检查防火墙状态
firewall-cmd --state

#开启防火墙
systemctl restart firewalld.service

#开启6379端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent

#重新载入配置
firewall-cmd --reload

#查看已开放的端口
firewall-cmd --list-ports

（7）lnmp自带重启redis命令

/etc/init.d/redis restart

由于已经设置了redis密码，会有如下错误提示

配置文件：/etc/init.d/redis 加上REDISPASSWORD 密码变量。

配置好后重启就可以了。
