Docker 安装 Redis - firemail - Powered by Discuz!

首先，创建目录redis,用于存放后面的相关东西。

runoob@runoob:~$ mkdir -p ~/redis ~/redis/data

复制代码

data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录

进入创建的redis目录，创建Dockerfile

docker-entrypoint.sh 内容

#!/bin/sh
set -e
# first arg is `-f` or `--some-option`
# or first arg is `something.conf`
if [ "${1#-}" != "$1" ] || [ "${1%.conf}" != "$1" ]; then
set -- redis-server "$@"
fi
# allow the container to be started with `--user`
if [ "$1" = 'redis-server' -a "$(id -u)" = '0' ]; then
chown -R redis .
exec gosu redis "$0" "$@"
fi
exec "$@"

runoob@runoob:~/redis$ docker build -t redis:3.2 .

runoob@runoob:~/redis$ docker images redis
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 3.2 43c923d57784 2 weeks ago 193.9 MB

runoob@runoob:~/redis$ docker run --name redis -p 6379:6379 -v $PWD/data:/data -d redis:3.2 redis-server --appendonly yes

-p 6379:6379 :将容器的6379端口映射到主机的6379端口

-v $PWD/data:/data :将主机中当前目录下的data挂载到容器的/data

redis-server --appendonly yes :在容器执行redis-server启动命令，并打开redis持久化配置

出现如下错误：

docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"docker-entrypoint.sh\": executable file not found in $PATH".

在COPY后加上下面一句话：

RUN chmod +x /usr/local/bin/docker-entrypoint.sh

复制代码

docker exec -it redis bash

~ redis-cli
redis 127.0.0.1:6379>

127.0.0.1:6379> set key1 "tutut"

127.0.0.1:6379> get key1

"tutut"

远程连接测试
redis-cli -h 192.168.134.106 -p 6379

192.168.134.106:6379> get key1
"tutut"

exit退出
测试连接成功！

使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1

runoob@runoob:~/redis$ docker run -it redis:3.2 redis-cli -h 172.17.0.1
