Windows系统下安装分布式事务seata服务端，配置中心使用nacos

官网下载地址： Releases · seata/seata · GitHub

这里我下载的是1.2版本

然后进行解压压缩包

解压后里面文件目录如下

 进入配置文件conf

默认目录如下

 修改 registry.conf 为如下，这里没有用的配置删除了，只留nacos的配置了；

 代码如下：

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "192.168.1.215"
    namespace = "public"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
   
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "file"

  nacos {
    serverAddr = "192.168.1.215"
    namespace = "public"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
 
}

修改  file.conf 配置文件，修改mode为db ，同时修改数据库链接信息；这里也可以不修改 file的配置文件，这里看有没有，如果用不用db模式启动，就需要这个file配置文件了

添加 nacos-config.txt 文件

代码如下：

transport.type=TCP
transport.server=NIO
transport.heartbeat=true

修改地方

 这里的语法为： service.vgroup_mapping.${your-service-gruop}=default ，中间的
${your-service-gruop} 为自己定义的服务组名称， 这里需要我们在程序的配置文件中配置。

然后创建 nacos-config.py 

#!/usr/bin/env python3
#  -*- coding: UTF-8 -*-

import http.client
import sys

if len(sys.argv) != 2:
    print ('python nacos-config.py nacosIp')
    exit()

headers = {
    'content-type': "application/x-www-form-urlencoded"
}

hasError = False
for line in open('nacos-config.txt'):
    pair = line.split('=')
    if len(pair) < 2:
        continue
    print (line),
    url_prefix = sys.argv[1] + ':8848'
    conn = http.client.HTTPConnection(url_prefix)
    url_postfix = '/nacos/v1/cs/configs?dataId={}&group=SEATA_GROUP&content={}'.format(str(pair[0]),str(line[line.index('=')+1:])).strip()
    conn.request("POST", url_postfix, headers=headers)
    res = conn.getresponse()
    data = res.read()
    if data.decode("utf-8") != "true":
        hasError = True
if hasError:
    print ("init nacos config fail.")
else:
    print ("init nacos config finished, please start seata-server.")

然后创建 nacos-config.sh，如果不知道怎么创建 .sh 文件，可以先创建text文件，然后修改后缀名

#!/usr/bin/env bash
if [ $# != 1 ]; then
echo "./nacos-config.sh nacosIp"
exit -1
fi

nacosIp=$1
echo "set nacosIp=$nacosIp"
error=0

for line in $(cat nacos-config.txt)

do

key=${line%%=*}
value=${line#*=}
echo "\r\n set "${key}" = "${value}

result=`curl -X POST "http://$nacosIp:8848/nacos/v1/cs/configs?dataId=$key&group=SEATA_GROUP&content=$value"`

if [ "$result"x == "true"x ]; then

  echo "\033[42;37m $result \033[0m"

else

  echo "\033[41;37 $result \033[0m"
  let error++

fi

done


if [ $error -eq 0 ]; then

echo  "\r\n\033[42;37m init nacos config finished, please start seata-server. \033[0m"

else

echo  "\r\n\033[41;33m init nacos config fail. \033[0m"

fi

创建完相关文件后，目录如下 

# 初始化 seata 的nacos配置
# 注意: 这里要保证nacos是已经正常运行的

 然后再conf目录下执行下面代码，将seata配置信息添加到nacos中

C:\Users\admin-xu\Desktop\seata-server-1.2.0\seata\conf>nacos-config.sh 192.168.1.215

打印日志如下

 去nacos配置中心查看

 开始启动seata，进入bin目录下

 执行命令

C:\Users\admin-xu\Desktop\seata-server-1.2.0\seata\bin>seata-server.bat -p 9000 -m db

打印日志

 去nacos服务中看下是否注册到nacos的注册中心，如下信息启动成功
