文章目錄

• ​​1. 建立檔案config.txt​​
• ​​2. 建立nacos-config.sh​​
• ​​3. 配置導入nacos配置中心​​
• ​​4. 配置驗證​​

1. 建立檔案config.txt

在seata的安裝檔案夾下建立檔案config.txt

[root@node2 ~]# cd /app/seata/seata-server-1.4.2/
[root@node2 seata-server-1.4.2]# vim config.txt      

說明：

第一行：這裡order-service值得是訂單子產品的服務

從第二行開始：下面是資料庫資訊根據自己的實際情況配置

注意點：不能添加中文注釋

添加以下内容：

service.vgroupMapping.order-service=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/ry-seata?useUnicode=true
store.db.user=root
store.db.password=123456
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000      

上面的檔案是精簡後的部分，完整檔案可在github中找到

2. 建立nacos-config.sh

在conf/檔案夾下下載下傳檔案

​​​https://github.com/seata/seata/blob/develop/script/config-center/nacos/nacos-config.sh ​​ 用于将上面的seata配置資訊導入到nacos 執行下面的指令

[root@node2 seata-server-1.4.2]# cd conf
[root@node2 conf]# vim nacos-config.sh

if [ -z ${host} ]; then
    host=localhost
fi
if [ -z ${port} ]; then
    port=8848
fi
if [ -z ${group} ]; then
    group="SEATA_GROUP"
fi
if [ -z ${tenant} ]; then

    count=`expr $count + 1`

if [ ${failCount} -eq 0 ]; then
  echo " Init nacos config finished, please start seata-server. "
else
  echo " init nacos config fail. "
fi      

3. 配置導入nacos配置中心

将seata配置資訊導入到nacos config配置中心

sh nacos-config.sh -h 127.0.0.1      

• -h後面是nacos配置中心的位址

  操作記錄：

[root@node2 conf]#  sh nacos-config.sh -h 127.0.0.1
set nacosAddr=127.0.0.1:8848
set group=SEATA_GROUP
Set service.vgroupMapping.order-service=default successfully 
Set store.mode=db successfully 
Set store.db.datasource=druid successfully 
Set store.db.dbType=mysql successfully 
Set store.db.driverClassName=com.mysql.cj.jdbc.Driver successfully 
Set store.db.url=jdbc:mysql://127.0.0.1:3306/ry-seata?useUnicode=true successfully 
Set store.db.user=root successfully 
Set store.db.password=123456 successfully 
Set store.db.minConn=5 successfully 
Set store.db.maxConn=30 successfully 
Set store.db.globalTable=global_table successfully 
Set store.db.branchTable=branch_table successfully 
Set store.db.queryLimit=100 successfully 
Set store.db.lockTable=lock_table successfully 
Set store.db.maxWait=5000 successfully 
=========================================================================
 Complete initialization parameters,  total-count:15 ,  failure-count:0 
=========================================================================
 Init nacos config finished, please start seata-server. 
[root@node2 conf]#      

4. 配置驗證

執行完成後登入到nacos 檢視配置中心的資料是否導入完畢，如圖所示
