1 部署配置

1.1 初始化数据库

• 使用[mysql脚本]，初始化 Seata 的 db 数据库

DROP TABLE IF EXISTS `branch_table`;
CREATE TABLE `branch_table` (
  `branch_id` bigint(20) NOT NULL,

SET FOREIGN_KEY_CHECKS = 1;

1.2 配置Nacos

1.2.1 新增命名空间

1.2.2 下载seata（1.1.0）源码

mkdir -p /opt/seata
cd /opt/seata
wget https://github.com/seata/seata/archive/refs/tags/v1.1.0.tar.gz
tar -zxvf seata-1.1.0.tar.gz

1.2.3 执行seata config-center 的 shell脚本

cd seata-1.1.0/script/config-center

## 编辑 config.txt 文件修改 自己对应的配置项

## 这边采用的是 nacos 作为注册中心和配置中心

cd nacos

./nacos-config.sh -h Nacos地址 -p Nacos地址端口 -g Nacos分组 -t Nacos命名空间

这样就配置好了nacos的配置

2 K8S 部署配置

2.1 新增命名空间

kubectl create namespace seata-ha

2.2 编辑配置文件

vim k8s-seata-ha-server-deploy.yaml

2.2 部署

kubectl create -f k8s-seata-ha-server-deploy.yaml
