docker安装redis并持久化数据

1. 创建挂载目录

sudo mkdir -p /home/redis/conf
sudo mkdir -p /home/redis/data
sudo touch /home/redis/conf/redis.conf

cat > /home/redis/conf/redis.conf << EOF
appendonly yes
EOF

root@k8s-master:/home/redis# ls
conf  data
root@k8s-master:/home/redis# tree /home/
/home/
└── redis
    ├── conf
    │   └── redis.conf
    └── data

3 directories, 1 file
root@k8s-master:/home/redis# 

2. 运行容器

docker run -p 6379:6379 --name redis --restart=always  \
-v /home/redis/data:/data  \
-v /home/redis/conf/redis.conf:/etc/redis/redis.conf  \
-d redis:5.0.5 redis-server /etc/redis/redis.conf

root@k8s-master:/home/redis# docker run -p 6379:6379 --name redis --restart=always  \
> -v /home/redis/data:/data  \
> -v /home/redis/conf/redis.conf:/etc/redis/redis.conf  \
> -d redis:5.0.5 redis-server /etc/redis/redis.conf
904689cd1b093c967f93072b5a2ad1df4c481515acf5188db4345853bfd25db3
root@k8s-master:/home/redis# docker ps -l
CONTAINER ID   IMAGE         COMMAND                  CREATED         STATUS         PORTS                                       NAMES
904689cd1b09   redis:5.0.5   "docker-entrypoint.s…"   6 seconds ago   Up 5 seconds   0.0.0.0:6379->6379/tcp, :::6379->6379/tcp   redis
root@k8s-master:/home/redis# 

3. 进入容器

docker exec -it redis /bin/bash #进入容器
redis-cli #登录redis
set name mqq
get name
exit

root@k8s-master:/home/redis# docker exec -it redis /bin/bash #进入容器
root@904689cd1b09:/data# redis-cli
127.0.0.1:6379> set name mqq
OK
127.0.0.1:6379> get name
"mqq"
127.0.0.1:6379> exit
root@904689cd1b09:/data# exit
exit
root@k8s-master:/home/redis# cd /home/redis/data/
root@k8s-master:/home/redis/data# ls
appendonly.aof
root@k8s-master:/home/redis/data# cat appendonly.aof 
*2
$6
SELECT
$1
0
*3
$3
set
$4
name
$3
mqq
root@k8s-master:/home/redis/data# 

4. 重启容器查看数据还在

docker rm -f redis #删除容器
docker run -p 6379:6379 --name redis --restart=always  -v /home/redis/data:/data -v /home/redis/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.5 redis-server /etc/redis/redis.conf #重新启动容器
docker exec -it redis /bin/bash #进入容器
redis-cli
get name
exit

root@k8s-master:/home/redis/data# docker rm -f redis
redis
root@k8s-master:/home/redis/data# docker run -p 6379:6379 --name redis --restart=always  -v /home/redis/data:/data -v /home/redis/conf/redis.conf:/etc/redis/redis.conf -d redis:5.0.5 redis-server /etc/redis/redis.conf
81a02a81e76a6b9cb7e322cb3d1c8c94888cbebbdfb37dbbf44dcf49f3f6f93e
root@k8s-master:/home/redis/data# docker exec -it redis /bin/bash
root@81a02a81e76a:/data# redis-cli  
127.0.0.1:6379> get name
"mqq"
127.0.0.1:6379> exit
root@81a02a81e76a:/data# exit 
exit
root@k8s-master:/home/redis/data#

5.用redis远程工具测试

这里是没有任何的密码

6. 给redis设置登录密码

6.1 修改配置文件

#这个文件添加了requirepass Maqiang，密码是Maqiang
cat /home/redis/conf/redis.conf
appendonly yes
requirepass Maqiang

docker restart redis #重启容器

6.2 用redis远程工具无密码无法登录

6.3 用redis远程工具用密码登录

密码是刚才设置的Maqiang
