云服务器搭建seata1.4.2和使用

在学习尚硅谷的seata，由于他用的版本是0.9，而我使用的是1.4.2，配置上稍微有些许的不同，我适当做了调整

我没有设置group分组，如果需要设置，可以在配置文件中留一下

                        1    云服务器Server端配置

先启动naocs端才可进行下一步操作

1.1修改conf/file.conf下的文件

mode改为db模式，修改db文件，注：mysql5.7之前和mysql5.7之后的driver不同，如果是高版本则修改为com.mysql.cj.jdbc.Driver。url为mysql路径

1.2.修改conf/registry.conf文件，

serverAddr为nacos地址，username和password为nacos账号密码、

1.3.创建文件名nacos-config.sh，在文件中添加下列代码

while getopts ":h:p:g:t:u:w:" opt
do
  case $opt in
  h)
    host=$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
done

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
    tenant=""
fi
if [[ -z ${username} ]]; then
    username=""
fi
if [[ -z ${password} ]]; then
    password=""
fi

nacosAddr=$host:$port
contentType="content-type:application/json;charset=UTF-8"

echo "set nacosAddr=$nacosAddr"
echo "set group=$group"

failCount=0
tempLog=$(mktemp -u)
function addConfig() {
  curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$1&group=$group&content=$2&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/null
  if [[ -z $(cat "${tempLog}") ]]; then
    echo " Please check the cluster status. "
    exit 1
  fi
  if [[ $(cat "${tempLog}") =~ "true" ]]; then
    echo "Set $1=$2 successfully "
  else
    echo "Set $1=$2 failure "
    (( failCount++ ))
  fi
}

count=0
for line in $(cat $(dirname "$PWD")/conf/config.txt | sed s/[[:space:]]//g); do
  (( count++ ))
	key=${line%%=*}
    value=${line#*=}
	addConfig "${key}" "${value}"
done

echo "========================================================================="
echo " Complete initialization parameters,  total-count:$count ,  failure-count:$failCount "
echo "========================================================================="

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

1.4.新建config.txt文件，添加下列内容

注：修改该文件中的mysql数据库内容

可以看到数据已成功导入进nacos了

 

1.5.执行命令，将配置文件内容上传到nacos中

sh nacos-config.sh -h [nacosIp地址] -p 8848 -g SEATA_GROUP -u [用户名]-w [密码]

1.6.创建seata数据库并导入表

sql文件可以在github中获取

https://github.com/seata/seata/blob/1.4.2/script/server/db/mysql.sql

create database seata;
use seata;

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`

    `xid`                       VARCHAR(128) NOT NULL,

    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)

  DEFAULT CHARSET = utf8;

1.7.启动seata

sh bin/seata-server.sh

可以看到seata已经成功启动了！ 

                              2  Client端配置

2.1 POM文件引入

2.2 application.yaml文件导入

    grouplist.default: [云服务器的ip地址]:8091

 2.3配置springbootMain方法，

不需要手动设置数据源了，添加@EnableAutoDataSourceProxy可以自动代理

@EnableDiscoveryClient
@EnableFeignClients
@EnableAutoDataSourceProxy //seata启用自动数据源代理
@SpringBootApplication/*(exclude =  DataSourceAutoConfiguration.class)*/
public class SeataAccountMain2003 {
    public static void main(String[] args) {
        SpringApplication.run(SeataOrderMain2001.class,args);
    }
}

2.4设置全局事务，

        name可以随便设置，但要保证唯一性
