修改网络配置后重启网络：

systemctl restart NetworkManager

# 安装Docker
sudo dnf install docker -y

# 启动Docker服务
sudo systemctl start docker
sudo systemctl enable docker

docker 配置代理：

vim /etc/docker/daemon.json

{
   "registry-mirrors":[
    "https://docker.1ms.run"
    ],
   "dns": ["8.8.8.8", "114.114.114.114"],
   "data-root": "/home/docker"
}

重启docker服务：

sudo systemctl restart docker

安装docker-compose

下载到指定目录：

sudo curl -L "https://github.com/docker/compose/releases/download/v2.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

添加可执行权限：

sudo chmod +x /usr/local/bin/docker-compose

# 创建项目目录
mkdir -p /data/mariadb/{data,config,logs}
cd /data/mariadb/

vim config/my.cnf

[mysqld]

datadir=/var/lib/mysql

port=3306

character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci

max_connections=1000

group_concat_max_len = 102400

创建 docker-compose.yml 文件：

vim docker-compose.yml

    image: mariadb:10.5
    container_name: mariadb
    restart: unless-stopped

# 修改目录权限，确保容器可以访问
sudo chown -R 1000:1000 ./data ./logs
sudo chmod -R 755 ./data ./logs ./config

# 启动服务
docker-compose up -d

# 查看服务状态
docker-compose ps

# 查看日志
docker-compose logs -f

# 连接到MariaDB
docker exec -it mariadb mysql -u root -p

# 在MySQL命令行中验证数据目录
SELECT @@datadir;

使用数据库自带工具备份：

挂载备份目录：

mount -t cifs -o username=administrator,password=Jjjt@china //192.168.32.188/diandaData /winshare

源数据库导出：

docker exec mariadb sh -c 'exec mariadb-dump -uxfyh -p"HN#xuefen#2025" --databases xfyh' > /winshare/xfyh/20251027.sql 2> error.log

自动执行：

vim mariadbBackupRun.sh

#!/bin/bash
current_day=$(date +"%Y-%m-%d")
docker exec mariadb sh -c 'exec mariadb-dump -uxfyh -p"HN#xuefen#2025" --databases xfyh' > /winshare/xfyh/$current_day.sql 2> error.log
 

chmod +x mariadbBackupRun.sh

crontab -e

30 1 * * 0-6  sh /root/mariadbBackupRun.sh 2>&1 > /root/mariadbBackup/log_incre_$(date +\%Y-\%m-\%d-\%H-\%M)

还原到目标数据库：

docker exec -i mariadb  sh -c 'exec mysql -uxfyh -p"HN#xuefen#2025"' < /winshare/xfyh/20251027.sql

启动docker 数据库：

#!/bin/bash
docker-compose down && docker-compose up -d
