Linux安装Temporal工作流引擎

使用Docker安装Temporal， 使用外部MySQL数据库

1. 初始化MySQL数据库

# 创建用户 temporal
CREATE USER 'temporal'@'%' IDENTIFIED BY 'temporal';

# 创建数据库 temporal
CREATE DATABASE `temporal` DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;
grant all privileges on `temporal`.* TO 'temporal'@'%';

# 创建数据库 temporal_visibility
CREATE DATABASE `temporal_visibility` DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;
grant all privileges on `temporal_visibility`.* TO 'temporal'@'%';

2. 配置文件

docker-compose.yml

services:
  temporal-init:
    image: temporalio/auto-setup:1.29.3
    container_name: temporal_init
    environment:
      DB: mysql8
      # 改为正确MySQL配置
      MYSQL_SEEDS: "192.168.2.215"
      DB_PORT: 3306
      MYSQL_USER: "temporal"
      MYSQL_PWD: "temporal"
      MYSQL_DB: "temporal"
      DEFAULT_NAMESPACE: "default"
    command: ["temporal-sql-tool", "create-schema", "-k", "default", "-v", "1.19"]
    restart: "no"
    
  temporal:
    image: temporalio/auto-setup:1.29.3
    container_name: temporal_server
    environment:
      # 使用外部 MySQL
      DB: mysql8
      MYSQL_SEEDS: "192.168.2.215"    # 你的 MySQL 地址
      DB_PORT: 3306
      MYSQL_USER: "temporal"
      MYSQL_PWD: "temporal"
      MYSQL_DB: "temporal"                 # Temporal 数据库
      DEFAULT_NAMESPACE: "default"
      # 这里填127.0.0.1会报错， 需要在ports将7233端口映射到宿主机， 填写宿主机的IP
      TEMPORAL_BROADCAST_ADDRESS: "192.168.2.215"
    ports:
      - "7233:7233"   # gRPC frontend
      - "7234:7234"   # history
      - "7235:7235"   # matching
      - "7239:7239"   # worker
      - "8088:8088"   # Temporal Web API (可选)
    depends_on:
      - temporal-init
    restart: always

  temporal-ui:
    image: temporalio/ui:2.45.0
    container_name: temporal_ui
    environment:
      TEMPORAL_ADDRESS: "temporal:7233"  # 指向 Temporal Server 容器名
      TEMPORAL_UI_PORT: "8080"
    ports:
      - "8080:8080"   # 浏览器访问
    depends_on:
      - temporal
    restart: always

temporal-init: 用于自动初始化数据
temporal: 启动核心进程
temporal-ui: 启动UI管理界面

3. 启动

# 启动
docker compose up -d
# 查看日志
docker logs --tail=100 -f temporal_server

销毁命令:

docker compose down
docker container list
