One, Linux install docker
Docker installation requires CentOS7 or higher to install
1. Check the CentOS version:
| cat /etc/redhat-release |
2. Install the required software packages
| sudo yum install -y yum-utils device-mapper-persistent-data lvm2 |
3. Set up stable mirror warehouse:
| sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo |
Carriage return
4. Enable edge and test mirror warehouse:
| sudo yum-config-manager --enable docker-ce-edge sudo yum-config-manager --enable docker-ce-testing |
5. Update the yum package index:
| sudo yum makecache fast |
6. Install the latest version of Docker:
| sudo yum install docker-ce |
- Choose y to continue
--Until the installation is complete
7. Start Docker
| sudo systemctl start docker |
8. Verify whether the startup is successful:
| sudo docker run hello-world |
Docker installation is complete!
Two, docker install fastdfs
1. View the image of fastdfs
| Docker search fastdfs |
2. Pull the fastDFS image containing nginx
Here is an example of delron/fastdfs
| docker pull delron/fastdfs |
3. Start the storage service
| docker run -d --network=host --name tracker -v /home/xxx/docker/fastdfs/tracker:/var/fdfs delron/fastdfs tracker |
4. Start the storage service
| docker run -d --network=host --name storage -e TRACKER_SERVER=10.0.14.50:22122 -v /home/xxx/docker/fastdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage |
5. View all containers
| docker ps -a |
- View the running container
| docker ps |
6. Modify Nginx port
In this image, nginx listens on port 8888 by default, if you don’t need to modify it, you can ignore this step
--Enter the storage container 7cac30fe4f4f to view the CONTAINER ID of storange in docker ps
| docker exec -it 7cac30fe4f4f bash |
| vi /etc/fdfs/storage.conf |
Modify the last line to:
| # the port of the web server on this storage server http.server_port=80 |
--Modify the Nginx port to be consistent with the above
| vi /usr/local/nginx/conf/nginx.conf |
--Restart the container 7cac30fe4f4f is the CONTAINER ID of storange in the docker ps view
| docker restart 7cac30fe4f4f |
7. Test whether the configuration is successful
--Copy a picture (a.png) to the directory /home/xxx/docker/fastdfs/storage
--Enter the storage container 7cac30fe4f4f to view the CONTAINER ID of storange in docker ps
| docker exec -it 7cac30fe4f4f bash |
--Enter the fdfs directory
| cd / var / fdfs |
--Run the command
| / usr / bin / fdfs_upload_file /etc/fdfs/client.conf a.png |
运行成功后会返回地址：
group1/M00/00/00/CgAOMl58eJuAXYfgAALnd0AYnuI035.png
- 在浏览器中访问
| http://10.0.14.50/group1/M00/00/00/CgAOMl58eJuAXYfgAALnd0AYnuI035.png |
fastDFS和 nginx部署完成！
三、docker安装redis
- 查看redis的镜像
| docker search redis |
2、拉取redis镜像
| docker pull redis |
3、启动
| docker run --name redis -p 6379:6379 -d --restart=always redis redis-server --appendonly yes --requirepass "bichart" |
参数讲解
--name为容器取一个唯一的名字
-p端口映射，把宿主机的端口映射到容器内的端口
--restar=always随容器启动而启动
redis-server --appendonly yes在容器里执行redis-server命令，打开redis持久化
--requirepass密码 （请自行设置）
4、查看容器
| docker ps |
5、连接进入容器
| docker exec -it 6e50f2be93f4 redis-cli |
6、测试
--输入密码
| auth admin123 |
--储存数据
| set a helloword |
--获取储存数据
| get a |
Redis数据库部署完成！
四、docker安装mysql 5.7
1、查看镜像
| docker search mysql |
2、拉取镜像
| sudo docker pull mysql:5.7 |
- 查看镜像
| sudo docker images |
4、创建文件夹保存数据
| mkdir -p /data/mysql/conf （保存mysql配置文件） mkdir -p /data/mysql/data （保存mysql数据） mkdir -p /data/mysql/log (保存mysql日志) |
- 创建容器 密码请自行设置
| sudo docker run -p 3306:3306 --name mysql -v /data/mysql/conf:/etc/mysql -v /data/mysql/log:/var/log/mysql -v /data/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7 |
参数说明
| -p 3306(本机端口):3306(容器端口) 将容器3306的端口映射到本机的3306端口 --name mysql 为创建的容易命名 -v /data/mysql/conf:/etc/mysql 将本地文件夹映射到容器的文件夹里 -e MYSQL_ROOT_PASSWORD=root 设置root的密码 -d 指定创建容器的image |
不同的镜像，对应容器里面的文件夹路径也不同，如果路径不存在会报错。如果想查看容易内的mysql文件的路径，可参考下面做法：
--创建一个守护态的docker容器
| sudo docker run -itd mysql:5.7 /bin/bash |
--查看容器信息
| docker ps -a |
--使用docker attach进入该容器
| sudo docker attach 407717ba3d18(对应容器的ID) |
Mysql数据库部署完成！
