1.部署 seata-server
1.創建seata-server需要的表
具體的 SQL 參考 https://github.com/seata/seata/tree/develop/script/server/db，這里使用的是 MySQL 的腳本，數據庫名稱為 seata
同時，也需要創建 undo_log 表， 可以參考 https://github.com/seata/seata/tree/develop/script/client/at/db
2.修改seata-server配置
將以下配置添加到 Nacos 配置中心，具體添加方法可以參考 https://github.com/seata/seata/tree/develop/script/config-center
[root@k8s-matser01 ~]# cat config.txt
ervice.vgroupMapping.my_test_tx_group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://10.2.1.12:30060/seata?useUnicode=true # 數據庫地址
store.db.user=root # seata數據庫的賬號
store.db.password=123456 # seata數據庫的密碼
[root@k8s-matser01 ~]# sh ./nacos/nacos-config.sh -h 10.2.1.12 -p 8848 -g SEATA_GROUP -u nacos -w nacos
參數說明:
-h: Nacos主機地址，默認是localhost
-p: Nacos主機端口，默認是8848
-g: 配置分組, the default value is 'SEATA_GROUP'.
-t: 租戶信息, 與Nacos的 "命名空間ID" 字段相對應, the default value is ''.
-u: Nacos用戶名, the default value is ''.
-w: Nacos密碼, the default value is ''.
[root@k8s-matser01 nacos]# cat nacos-config.sh
...
100 count=0
# 我這里改成了絕對路徑
101 for line in $(cat /root/nacos/config.txt | sed s/[[:space:]]//g); do
102 count=`expr $count + 1`
103 key=${line%%=*}
104 value=${line#*=}
···
2.部署 seata-server 到 Kubernetes
[root@k8s-matser01 ~]# cat seata.yaml
apiVersion: v1
kind: Service
metadata:
name: seata-ha-server
namespace: default
labels:

---

data:
registry.conf: |
registry {
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "10.2.1.12" #nacos的ip
}
}
config {
type = "nacos"
nacos {
serverAddr = "10.2.1.12" # nacos的ip
group = "SEATA_GROUP"
}
}
3.問題
# 這是我用的最新的seata鏡像,換成了seata:1.3.0就ok了，百度說了是jdk的問題
