Redis安装、设置和管理

摘要

• 安装
• 设置密码
• 本地访问
• 远程访问
• 实现图形化管理

安装

Ubuntu 22.04 LTS安装很简单

apt install redis

设置密码访问

配置文件在/etc/redis文件夹下：

vi /etc/redis/redis.conf

查找requirepass，取消前边的注释，设置成自己的密码

# IMPORTANT NOTE: starting with Redis 6 "requirepass" is just a compatibility
# layer on top of the new ACL system. The option effect will be just setting
# the password for the default user. Clients will still authenticate using
# AUTH <password> as usually, or more explicitly with AUTH default <password>
# if they follow the new protocol: both will work.
#
requirepass myPassword

重新启动服务：

systemctl restart redis

在redis服务器上测试连接

root@cap-server:/etc/redis# redis-cli
127.0.0.1:6379> config rewrite
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth myPassword
OK
127.0.0.1:6379> 

在另外一台Linux访问刚才安装的redis

redis的命令行是可以单独安装的：

1、安装redis-tools

Ubuntu 22.04 LTS

apt install redis-tools

2、连接远程redis

根据官网文章，尝试访问：

root@dev-server:/mnt/disk5t/portainer-ce# redis-cli -h 192.168.3.201 -a myPassword
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
Could not connect to Redis at 192.168.3.201:6379: Connection refused

怀疑是redis不允许127.0.0.1之外的IP访问，接下来：

3、修改redis.conf

打开配置文件

vi /etc/redis/redis.conf

注释掉bind 127.0.0.1 ::1

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all available network interfaces on the host machine.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only on the
# IPv4 loopback interface address (this means Redis will only be able to
# accept client connections from the same host that it is running on).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT OUT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# bind 127.0.0.1 ::1

重新启动redis

systemctl restart redis

4、再次连接远程redis

root@dev-server:/mnt/disk5t/portainer-ce# redis-cli -h 192.168.3.201 -a myPassword
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
192.168.3.201:6379> 

Redis Insight

1、安装

根据官网文章编排出下述文件：

version: '3.3'
services:
  redis_insight:
    # 镜像                                                  #  ↓↓↓↓↓ --- 1、 修改镜像版本号，或者干脆写成latest
    image: redis/redisinsight:latest
    container_name: redis-insight # 容器名
    restart: always
    volumes:
      #   ↓↓↓↓↓ ------------------------------------------------------- 2、 修改数据库以及证书存储路径
      - ./data:/data
    ports: # 端口映射
      - "5540:5540"
    environment: # 环境变量
      - TZ=Asia/Shanghai

启动

docker-compose up -d

首次启动后报错，用docker logs查看原因是很清晰的：对data目录的权限不够

chmod -R 777 data

重新启动容器

docker-compose restart

2、使用

首次打开：

勾选了默认设置，并提交后：

添加第一个数据库

在上一个图片中，选择：

下图中要把127.0.0.1换掉，因为Redis Insight是运行在容器里，容器内部并没有安装Redis。我们的Redis是安装在物理主机，所以要把IP地址换成192.168.3.201

添加成功了：

只贴一张图：

后记

这篇文章基本涵盖了redis入门级的方方面面，后续会不断完善这篇文章。
