在成功安装配置前，说一个报错信息：

io.seata.common.loader.EnhancedServiceNotFoundException: not found service provider for : io.seata.core.store.DistributedLocker

所用版本：docker pull seataio/seata-server  默认TAG：latest，两个配置文件：registry.conf和file.conf 应该配置正确的，这个报错我没有找到对应的解决方法，哎。。

最后通过指定版本 seataio/seata-serve:1.3.0 和seataio/seata-serve:1.4.2  这两个版本配置成功，其它版本就没有测试过了。

进入正题，记录我通过Docker 安装Seata 并注册进Nacos的过程及配置文件信息：

一、Seata 配置

1、docker 下载seata 镜像  官网下载地址：http://seata.io/zh-cn/blog/download.html  查看各版本

docker pull seataio/seata-server:1.4.2

2、 宿主机创建配置文件目录，用于挂载文件，位置自定

###配置文件目录
mkdir /root/dev/docker/seata/seata-config
##日志文件目录
mkdir /root/dev/docker/seata/logs

3、Seata 两个配置文件信息

registry.conf：注意服务器的地址等信息

#服务,将type从file改成nacos,将seata服务配置进nacos
registry {

  type = "nacos"
  nacos {
    application = "seata-server"
    serverAddr = "106.15.38.88:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
 
config {
  # file、nacos 、apollo、zk、consul、etcd3
## 注意路径，这只是一种配置写法
 type = "file"
 file {
    name = "file:/root/dev/docker/seata/seata-config/file.conf"
  }
}

file.conf：注意mode 类型及mysql 地址

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db" ## 原来为file
 
  ## file store property
  file {
    ## store location dir
    dir = "sessionStore"
    # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
    maxBranchSessionSize = 16384
    # globe session size , if exceeded throws exceptions
    maxGlobalSessionSize = 512
    # file buffer size , if exceeded allocate new buffer
    fileWriteBufferCacheSize = 16384
    # when recover batch read size
    sessionReloadReadSize = 100
    # async, sync
    flushDiskMode = async
  }

  ## database store property
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.cj.jdbc.Driver"
    ## 因为设置为db，所以需要选择数据库，这里设置数据库及密码，seata是需要创建的，默认的表是通过脚本运行得到的
     url = "jdbc:mysql://106.15.38.88:3306/seata?serverTimezone=GMT%2B8"
    user = "root"
    password = "123456"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

4、创建seata数据库和表，全局事务会话信息由3块内容构成，全局事务-->分支事务-->全局锁，对应表global_table、branch_table、lock_table，库名自定，与file.conf的mysql 配置信息要一致

mysql.sql传送门

 
-- -------------------------------- 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,

    `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`

    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

二、将seata 中的config.txt配置信息导入到nacos配置中心

1、配置信息

##创建两个文件
touch config.txt
touch nacos-config.sh

config.txt：注意service.vgroupMapping.my_test_tx_group=default 和mysql 信息修改

nacos-config.sh： 不用修改

echo "========================================================================="

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

2、在Linux 中执行 nacos-config.sh 推送信息，nacos服务必须8848的端口启动否则执行不生效

sh nacos-config.sh -h 106.15.38.88 -p 8848 -g SEATA_GROUP  -u nacos -w nacos
 ### 106.15.38.88 为nacos的服务器地址

注意：我在执行时，config.txt 和nacos-config.sh放在了同一目录出错了，nacos-config.sh 找的是自己所在目录的上一层目录的config.txt，小问题

执行结果

 三、启动seata

docker run -it -d   -p 8091:8091 \
-v /root/dev/docker/seata/seata-config/registry.conf:/seata-server/resources/registry.conf \
-v /root/dev/docker/seata/seata-config/file.conf:/seata-server/resources/file.conf \
-v /root/dev/docker/seata/logs:/root/logs \
-e SEATA_IP=106.15.38.88 \   ## 指定外网ip地址，NettyClientChannelManager可通过外网ip访问
-e SEATA_PORT=8091 \
--name seata1.4.2  seataio/seata-server:1.4.2

注意配置文件的对应路径，我也试过其它启动配置方法，失败了，暂且用这种吧

启动成功后，可在nacos服务列表中看到seata-server

至此整个过程结束
