基于Docker Compose部署Traccar容器与主机MySQL的完整指南-优快云博客

本文链接：https://blog.youkuaiyun.com/armcsdn/article/details/149195304

Traccar Docker镜像内嵌了H2数据库，该数据库容量有限，当达到一定容量时，定位数据无法写入会导致无法定位显示。为此有必要为Traccar 配置外部数据库。根据官网文档和自身经验我选择了MySQL。

软件环境为ubuntu server 24.04版，Traccar 镜像为最新版。Mysql非容器版为主机安装版。硬件设备选用HP T530小主机，硬盘128GB，内存8GB.

如何拉取Traccar 镜像本文不再说明。请读者自行解决。

1安装MySQL

查看版本.

mysql --version

如果没有安装会出现：

安装

sudo apt update && apt install mysql-server

安装后查看版本

安装完成后，可以通过以下命令验证 MySQL 是否正常运行。如果服务正常运行，你会看到类似“active (running)”的状态。

sudo systemctl status mysql

2创建为Traccar 配套MySQL的数据库

sudo mysql -u root -p

输入 root 密码后进入 MySQL 命令行。

创建数据库

CREATE DATABASE traccardb DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

创建用户并设置密码

CREATE USER 'traccardb'@'%' IDENTIFIED BY 'yourpassword';

yourpassword改成你自己的密码，下文遇到有 yourpassword地方请使用你设置的密码。

`'%'` 表示允许任意主机连接，也可以用 `'localhost'` 限制只允许本机连接。

授权用户访问数据库

GRANT ALL PRIVILEGES ON traccardb.* TO 'traccardb'@'%';

这里用户名和数据库名都是traccardb，可以不一样。

刷新权限

FLUSH PRIVILEGES;

3配置数据库

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

4新建yml文件为Traccar配置数据库

如果先前有Traccar容器运行，可以先使用如下命令，停止并删除当前运行的容器。

docker stop traccar
docker rm traccar

重新运行容器，不使用 --restart 参数：

docker run -d --name traccar \
           -v /home/t503/traccar/to/data:/opt/traccar/data \
           -p 18082:8082 -p 15055:5055 \
           registry.cn-hangzhou.aliyuncs.com/armxu_docker/traccar

上面命令请不要照搬，仅供参考。

运行以下命令查看容器的重启策略：

docker inspect traccar --format '{{ .HostConfig.RestartPolicy.Name }}'

如果输出为 no，则表示容器不会自动重启

再次运行

docker stop traccar
docker rm traccar

ubuntu 查看IPV4地址

ifconfig

在服务器上创建项目目录：

mkdir -p ~/traccar-docker
cd ~/traccar-docker

创建 docker-compose.yml 文件：

nano docker-compose.yml

复制下面内容：

services:
  traccar:
    image: registry.cn-hangzhou.aliyuncs.com/armxu_docker/traccar
    container_name: traccar
    restart: unless-stopped
