解决Redis开启远程访问及密码问题

Redis开启远程访问及密码，具体介绍如下所示：

一、开启远程访问

1.开放端口

firewall-cmd --zone=public --add-port=6379
firewall-cmd --zone=public --add-port=6379 --permanent

2.查看已开放端口

firewall-cmd --list-port

3.修改配置文件

vim redis.conf

将bind 127.0.0.1 注释或者改为bind 0.0.0.0

将protected-mode yes  改为protected-mode no;

二、设置密码

找到 # requirepass foobared 将注释去掉，修改foobared 为自己想要的密码，如 requirepass 123456

之后重启即可

systemctl restart redis

ps：Redis启动报错解决

报错

>删除pid文件

 cd /var/run
 mv redis_6379.pid redis_6379.pid_bak

>删除dump.rdb（内存快照）文件

 cd /var/lib/redis/6379
 mv dump.rdb dump.rdb_bak

>之后查看是否还有redis服务启动

 ps -ef |grep redis
 kill -9 

>之后重启即可
