解决服务器Redis无法连接问题

解决服务器Redis无法连接问题

2023.3.21

找到你的redis配置文件，进行以下步骤修改。（本人的在

/etc/redis.conf

，如果找不到，直接创建一个，然后度娘一个默认的redis配置文件粘贴上去即可，启动时使用命令

redis-cli +文件路径

，下文会讲）

1. 修改bind，默认为bind 127.0.0.1，将其注释(前面加个#)，如果没有找到bind 127.0.0.1或已经注释，跳过此步。

# By default Redis listens for connections from all the network interfaces# available on the server. It is possible to listen to just one or multiple# interfaces using the "bind" configuration directive, followed by one or# more IP addresses.## Examples:# bind 127.0.0.1

1. 关闭保护模式，默认为protected-mode yes,将yes修改为no，如果没有找到protected-mode yes，可以随意另起一行添加protected-mode no；或已经修改为protected-mode no，跳过此步。

# When protected mode is on and if:## 1) The server is not binding explicitly to a set of addresses using the#    "bind" directive.# 2) No password is configured.## The server only accepts connections from clients connecting from the# IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain# sockets.## By default protected mode is enabled. You should disable it only if# you are sure you want clients from other hosts to connect to Redis# even if no authentication is configured, nor a specific set of interfaces# are explicitly listed using the "bind" directive.
protected-mode no

1. 如果有需求，设置密码（没有需求则跳过），添加一行requirepass 123456，作用是设置连接密码为123456，如有需求可以修改密码

################################## SECURITY #################################### Require clients to issue AUTH <PASSWORD> before processing any other# commands.  This might be useful in environments in which you do not trust# others with access to the host running redis-server.## This should stay commented out for backward compatibility and because most# people do not need auth (e.g. they run their own servers).## Warning: since Redis is pretty fast an outside user can try up to# 150k passwords per second against a good box. This means that you should# use a very strong password otherwise it will be very easy to break.## requirepass foobared
requirepass 123456

1. 重启你的redis，在安装redis的位置使用命令redis-cli shutdown，然后再使用命令./redis-server /etc/redis.conf启动redis，请注意，如果你修改的配置文件在其他地方：例如/opt/redis/redis.conf，请你使用./redis-server /opt/redis/redis.conf启动redis。

如果启动后无法进行其他操作，请使用

Ctrl+C

结束该进程后，找到刚刚修改的配置文件，找到并修改为或者添加

 daemonize=yes

（稍微提一嘴，windows版本不支持），然后再启动redis。

 daemonize=yes

最后关闭你的防火墙，或者将redis加入白名单，这里只做关闭处理，这一步操作因linux版本而异

systemctl status firewalld.service  #查看防火墙状态
systemctl stop firewalld.service    #关闭防火墙
