构建自己专属seata-server 镜像(分布式事务)？（第二篇）

码云地址：https://gitee.com/jessyxu/yc-seata-server

一.镜像构建前确保自己的seata-server 能够启动成功！

seata-server

官方建议：JDK版本不低于 1.8.0_281版本，兼容JDK 8、JDK11,可使用OpenJDK 8/11、Alibaba Dragonwell 8/、BiShengJDK 8/11

一 部署前准备

1.1 导入数据库脚本

导入数据库脚本前需要创建数据库

方式一：

Seata官方提供的数据库脚本

将/script/server/db/mysql.sql导入数据库中

方式二：

本文最上方csdn资源-提供的数据库脚本，包括Seata相关表、Seata在Nacos中的配置、环境相关配置信息

将yc-database项目中的/java微服务/{version}/nacos-mysql.sql导入数据库中

1.2 修改配置文件

注册至Nacos

打开/conf/application.yml配置文件，找到第11行，修改Nacos相关配置,如下所示

spring:
  application:
    name: seata-server
  cloud:
    nacos:
      discovery:
        # 服务注册地址
        server-addr: 127.0.0.1:30099
      config:
        server-addr: ${spring.cloud.nacos.discovery.server-addr}

读取nacos上的配置

打开/conf/application.yml配置文件，找到第46行,如下所示，

seata-server.properties为Nacos的配置

seata:
  config:
    # support: nacos 、 consul 、 apollo 、 zk  、 etcd3
    type: nacos
    nacos:
      # nacos ip地址
      server-addr: ${spring.cloud.nacos.discovery.server-addr}
      group: DEFAULT_GROUP
      namespace:
      username: "nacos"
      password: "nacos"
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      # 读取nacos上的配置文件
      data-id: seata-server.properties

1.3 增加Nacos配置

打开Nacos控制台并登录，依次点击【配置管理】-【配置列表】-【public】，点击右侧【+】,

• Data ID：seata-server （注意：和上述1.2中读取nacos上的配置中的data-id名称保持一致）
• Group：默认即可
• 配置格式：Properties （注意：和上述1.2中读取nacos上的配置中的data-id格式保持一致）
• 配置内容：复制/script/config-center/config.txt所有内容，并做如下调整

# 第26行
#######事务分组名#######
service.vgroupMapping.default_tx_group=default

# 第28行
#######Seata服务地址#######
service.default.grouplist=127.0.0.1:30095

# 第69-71
######mode改成db模式(根据实际场景修改)######
store.mode=db
store.lock.mode=db
store.session.mode=db

# 第86-89行
######MySQL配置内容######
store.db.datasource=druid
store.db.dbType=mysql
# MySQL5.7.x 驱动为com.mysql.jdbc.Driver,MySQL8.0.x驱动为com.mysql.cj.jdbc.Driver
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/yc_nacos?characterEncoding=utf8&rewriteBatchedStatements=true&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=GMT%2B8
store.db.user=username
store.db.password=password

二、启动、停止操作

2.1 Windows环境

• 启动：双击seata-server.bat
• 停止：双击shutdown.bat

2.2 Linux环境

# 启动
sh startup.sh

# 停止
sh shutdown.sh

三 访问控制台

• 访问地址： http://127.0.0.1:30095
• 用户名：seata
• 密码：seata

四 常见问题

如果直接使用官方下载的安装包并在JDK11环境下运行，需要将bin/seata-server.sh文件中第132行替换成如下内容

JAVA_MAJOR_VERSION=$($JAVACMD -version 2>&1 | head -1 | cut -d'"' -f2 | sed 's/^1\.//' | cut -d'.' -f1)

二、构建docker镜像

nacos 配置文件如下
