一键部署Docker中间件简单方法-redis为例

一键部署Docker中间件简单方法-redis为例

---

背景

想能够快速部署一些中间件.
写文档虽然可以, 但是总会有人问, 能够一键部署应该最好不过.

---

下载以及导出镜像

docker pull redis:7.2
docker save redis:7.2 |gzip > redis_docker_7.2.tar.gz

---

编写脚本进行容器部署

export password=mustchange
mkdir -p /data/redis/
read -p "请输入redis的密码: " -a password
cat > /data/redis/redis.conf <<EOF

docker rm -f redis

docker load -i redis_docker_7.2.tar.gz 

docker run -p 6379:6379 --name redis --restart=always -v /data/redis/redis.conf:/etc/redis/redis.conf  -v /data/redis/data:/data/redis -d redis:7.2   redis-server /etc/redis/redis.conf

---

处理方式

将第一的脚本 保存为 deployredis
与导出的Redis镜像文件放在同一目录
然后给deployredis 赋予 可执行权限
然后执行即可.

---

效果

[root@oracle12c redis]# ./deployredis
请输入redis的密码: somepassword
redis
Loaded image: redis:7.2
c8cbea0bb96f8cbd11aefc6a3550fb2470a84a192a06cc3859e754c13daf1be7
效果为:

docker ps
CONTAINER ID        IMAGE                                      COMMAND                  CREATED
c8cbea0bb96f        redis:7.2                                  "docker-entrypoint.s…"   3 seconds ago 

登录验证
[root@oracle12c redis]# docker exec -it redis bash
root@c8cbea0bb96f:/data# redis-cli
127.0.0.1:6379> auth somepassword
OK
127.0.0.1:6379>

---

其他处理

如果想修改密码
vim /data/redis/redis.conf
修改requirepass 的字段值 然后重启redis就可以了
docker restart redis 

效果为:

[root@oracle12c redis]# vim /data/redis/redis.conf
[root@oracle12c redis]# docker restart redis
redis
[root@oracle12c redis]# docker exec -it redis bash
root@c8cbea0bb96f:/data# redis-cli
127.0.0.1:6379> auth zhaobsh
OK
127.0.0.1:6379> info
# Server
