# 新增挂载配置文件夹

因为 redis 默认配置你会发现只能够本地连接，不能进行远程访问，使用 Redis Desktop Manager连接都会报错，因此需要手动挂载 redis 配置文件/ 新建data和conf两个文件夹，位置随意。例如：

mkdir -p /export/servers/redis/conf
mkdir -p /export/servers/redis/data

# 新增Redis配置文件

vim /export/servers/redis/conf/redis.conf
1

内容如下：

#bind 127.0.0.1 
protected-mode no
appendonly yes 
requirepass root
1

  • 将bind 127.0.0.1注释掉，保证可以从远程访问到该Redis，不单单是从本地
  • appendonly：开启数据持久化到磁盘，由于开启了磁盘映射，数据最终将落到/export/server/redis/data目录下
  • requirepass：设置访问密码为root

# 创建redis容器并启动

docker run --restart=always --privileged=true \
-p 6379:6379 --name redis \
-v /export/servers/redis/data:/data \
-v /export/servers/redis/conf/redis.conf:/etc/redis/redis.conf \
-d redis redis-server /etc/redis/redis.conf

  • docker run表示运行的意思
  • --name redis表示运行容器的名字叫redis
  • -p 6379:6379表示将服务器的6379（冒号前的6379）端口映射到docker的6379（冒号后的6379）端口，这样就可以通过服务器的端口访问到docker容器的端口了
  • -d 表示以后台服务的形式运行redis
  • -v /export/servers/redis/data:/data表示将服务器上的/export/server/redis/data映射为docker容器上的/data ，这样/data中产生的数据就可以持久化到本地的目录下了
  • -v /export/servers/redis/conf/redis.conf:/etc/redis/redis.conf表示将本地/export/server/redis/conf/redis.conf映射为docker容器上的/etc/redis/redis.conf，这样再配合指令末尾的redis redis-server /etc/redis/redis.conf实现让docker容器运行时使用本地配置的Redis配置文件的功能了。
  • redis redis-server /etc/redis/redis.conf表示运行redis服务器程序，并且指定运行时的配置文件
