前言：之前我們只將nacos注冊中心和seata進行了整合，如果需要實現完整的功能還需要與nacos的配置中心進行整合。

一、配置管理

1. 創建文件config.txt

在seata的安裝文件夾下創建文件config.txt

[root@localhost ~]# cd /app/seata/ [root@localhost seata]# vim config.txt

添加一下內容：

# 這里order-service值得是訂單模塊的服務 service.vgroupMapping.order-service=default # 下面是數據庫信息根據自己的實際情況配置 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/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

上面的文件是精簡后的部分，完整文件可在github中找到

https://github.com/seata/seata/blob/develop/script/config-center/config.txt

2. 創建nacos-config.sh

在conf/文件夾下下載文件https://github.com/seata/seata/blob/develop/script/config-center/nacos/nacos-config.sh 用于將上面的seata配置信息導入到nacos 執行下面的命令

[root@localhost seata]# cd conf/ [root@localhost conf]# vim nacos-config.sh 內容比較多，建議直接下載吧 #!/bin/sh # Copyright 1999-2019 Seata.io Group. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at、 # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License.while getopts ":h:p:g:t:u:w:" opt docase $opt inh)host=$OPTARG;;p)port=$OPTARG;;g)group=$OPTARG;;t)tenant=$OPTARG;;u)username=$OPTARG;;w)password=$OPTARG;;?)echo " USAGE OPTION: $0 [-h host] [-p port] [-g group] [-t tenant] [-u username] [-w password] "exit 1;;esac doneif [ -z ${host} ]; thenhost=localhost fi if [ -z ${port} ]; thenport=8848 fi if [ -z ${group} ]; thengroup="SEATA_GROUP" fi if [ -z ${tenant} ]; thentenant="" fi if [ -z ${username} ]; thenusername="" fi if [ -z ${password} ]; thenpassword="" finacosAddr=$host:$port contentType="content-type:application/json;charset=UTF-8"echo "set nacosAddr=$nacosAddr" echo "set group=$group"urlencode() {length="${#1}"i=0while [ $length -gt $i ]; dochar="${1:$i:1}"case $char in[a-zA-Z0-9.~_-]) printf $char ;;*) printf '%%%02X' "'$char" ;;esaci=`expr $i + 1`done }failCount=0 tempLog=$(mktemp -u) function addConfig() {dataId=`urlencode $1`content=`urlencode $2`curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$dataId&group=$group&content=$content&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/nullif [ -z $(cat "${tempLog}") ]; thenecho " Please check the cluster status.

" elseecho " init nacos config fail. " fi

3. 配置導入nacos配置中心

將seata配置信息導入到nacos config配置中心

[root@localhost conf]# sh nacos-config.sh -h 127.0.0.1set 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/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@localhost conf]#

-h后面是nacos配置中心的地址

4. 配置驗證

執行完成后登錄到nacos 查看配置中心的數據是否導入完畢，如圖所示
