Docker+nacos+seata1.3.0安裝與使用配置教程

Posted on by

在此之前我搞瞭一天，雖然seata好用，用起來也超級簡單，但是安裝配置是真的麻煩，遇見瞭各種坑，下面來進入正題。o(╥﹏╥)o

一 . 版本

   註意：如果版本不匹配也會有各種報錯，可以根據官網匹配版本。

seata：1.3.0
alibaba.cloud：2.2.3.RELEASE
nacos：2.0.2

二. docker安裝搭建seata服務端

         2.1 下載seata鏡像

docker pull seataio/seata-server:1.3.0

        2.2 在Linux目錄下創建registry.conf，我的路徑在/data/seate/registry.conf，接下來的所有創建都在這個目錄下

cd /data
mkdir seate
vim registry.conf

        2.3 registry.conf中的內容如下

registry {
  type = "nacos"
 
  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = ""
    password = ""
  }
}
 
config {
  type = "nacos"
 
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = ""
    password = ""
  }
}

註意registry和config需要在同一個組下,註冊中心我用的是nacos，註意nacos的地址要改。

—–>>>這裡我插一句，需要新建一個數據庫seata，並且新建三張表，

-- -------------------------------- 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,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,
    `application_id`            VARCHAR(32),
    `transaction_service_group` VARCHAR(32),
    `transaction_name`          VARCHAR(128),
    `timeout`                   INT,
    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;
 
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
    `branch_id`         BIGINT       NOT NULL,
    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,
    `client_id`         VARCHAR(64),
    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;
 
-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(96),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),
    `table_name`     VARCHAR(32),
    `pk`             VARCHAR(36),
    `gmt_create`     DATETIME,
    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

        實現分佈式每個業務庫都要加一張表undo_log，不然會報錯，

CREATE TABLE `undo_log` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主鍵',
  `branch_id` bigint(20) NOT NULL COMMENT 'branch transaction id',
  `xid` varchar(100) NOT NULL COMMENT 'global transaction id',
  `context` varchar(128) NOT NULL COMMENT 'undo_log context,such as serialization',
  `rollback_info` longblob NOT NULL COMMENT 'rollback info',
  `log_status` int(11) NOT NULL COMMENT '0:normal status,1:defense status',
  `log_created` datetime(6) NOT NULL COMMENT 'create datetime',
  `log_modified` datetime(6) NOT NULL COMMENT 'modify datetime',
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='AT transaction mode undo table';

2.4 創建推送配置文件 vim config.txt，是將文件中的配置推送到nacos中去。

vim config.txt
service.vgroupMapping.btb_tx_group=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://172.0.0.1:3306/seata?useUnicode=true
store.db.user=root
store.db.password=root
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

註意btb_tx_group需要與客戶端保持一致,順便註意數據庫驅動，如果是8以上用我的這個驅動，5.7的用com.mysql.jdbc.Driver

        2.5 創建推送腳本，因為執行腳本要在config.txt的下一層，所有加一層目錄

mkdir sh
cd sh
vim nacos-config.sh

內容如下：最好不要有任何的修改

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
    ;;

    ;;
  ?)
    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")/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

        2.6 執行推送腳本，後面是nacos的ip地址，如果端口不是8848還需要加一個-p 8884你的端口

bash nacos-config.sh -h 127.0.0.1

        2.7 創建容器，註意SEATA_IP如果是阿裡雲服務器需要寫外網ip

docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=172.0.0.1 -e SEATA_CONFIG_NAME=file:/data/seata/registry -v /data/seata:/data/seata  seataio/seata-server:1.3.0

三 . 客戶端（也就是微服務，項目中使用seata）

3.1 pom.xml 引入依賴

<!-- seata分佈式事務-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>io.seata</groupId>
                    <artifactId>seata-spring-boot-starter</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>io.seata</groupId>
            <artifactId>seata-spring-boot-starter</artifactId>
            <version>1.3.0</version>
        </dependency>

註意這裡一定要剔除原來自帶的 io.seata包，並且服務端和客戶端的包版本要一致。

3.2 配置項目配置文件

#seata
seata.application-id=${spring.application.name}
seata.tx-service-group=btb_tx_group
seata.config.type=nacos
seata.config.nacos.server-addr=172.0.0.1:8848
seata.config.nacos.group=SEATA_GROUP
seata.registry.type=nacos
seata.registry.nacos.application=seata-server
seata.registry.nacos.server-addr=172.0.0.1:8848
seata.registry.nacos.group=SEATA_GROUP

註意：這裡的btb_tx_group要跟服務端的vgroupMapping後面的key保持一致，

如：service.vgroupMapping.btb_tx_group=default

3.3 加入註解使用

@GlobalTransactional

擴展： 我用的是一個數據庫，執行報錯，說我缺少主鍵，於是我在表undo_log加瞭一個增的主鍵id，上面的創建undo_log表的sql是我加瞭id的，官方給的是沒有id的。請知曉！！！！

問題：單數源是有報錯的，原因是因為我是一個數據庫，需要設置代理配置如下 ，根據自己實際情況是指配置文件，不然會報錯

#單數據源
seata.enable-auto-data-source-proxy=true
#多數據源
seata.enable-auto-data-source-proxy=false
