## 1.获取镜像 ##

## 使用下面命令获取最新版本的镜像，此时我的最新版本是1.3.0 
    ## 或者可以使用docker pull seataio/seata-server:1.3.0t获取指定版本的镜像
    docker pull seataio/seata-server:latest

## 2.运行容器并获取配置 ##

为方便我们对seata配置修改我们需要先运行下seata-server，然后将配置拷贝到宿主机中，完成之后删除之前配置并通过宿主机运行容器。

## 运行容器
    docker run --name seata-server -p 8091:8091 -d  seataio/seata-server:latest
    ## 将容器中的配置拷贝到/usr/local/seata-1.3.0
    docker cp seata-server:/seata-server /usr/local/seata-1.3.0
    ## 完成后就会在/usr/local/seata-1.3.0出现容器的配置，我们现在可以将原来容器停止并删除
    docker stop seata-server
    docekr rm seata-server

## 3.修改配置文件 ##

进入目录/usr/local/seata-1.3.0/resources中修改file.conf和registry.conf中的内容  
file.conf中的内容：

## 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.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://192.168.1.23:3306/seata"
        user = "root"
        password = "123456"
        minConn = 5
        maxConn = 30
        globalTable = "global_table"
        branchTable = "branch_table"
        lockTable = "lock_table"
        queryLimit = 100
        maxWait = 5000
      }
    
      ## redis store property
      redis { 
        host = "127.0.0.1"
        port = "6379"
        password = ""
        database = "0"
        minConn = 1
        maxConn = 10
        queryLimit = 100
      }

registry.conf内容：

registry { 
      # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
      ## 我们这里使用nacos作为注册中心，所以需要设置type为nacos并设置nacos的属性
      type = "nacos"
      nacos { 
        application = "seata-server"
        serverAddr = "192.168.1.23:8848"
        group = "SEATA_GROUP"
        ## 这里的namespace是你nacos服务的namespace的data-id，设置那里，到时就会在那个namespace中
        namespace = "a1493ff3-a94b-4f76-91af-7999fabff7d5"
        cluster = "default"
        username = "nacos"
        password = "nacos"
      }
    }
    
    config { 
      # file、nacos 、apollo、zk、consul、etcd3
      type = "file"
    
      file { 
        name = "file.conf"
      }
    }

这里配置完成后，需要初始化数据库，这里参考[另一篇博客][Link 1]的第二步。

## 3.启动seata ##

docker run -d --restart always  --name  seata-server -p 8091:8091  -v /usr/local/seata-1.3.0:/seata-server -e SEATA_IP=192.168.1.23 -e SEATA_PORT=8091 seataio/seata-server:latest

第一次启动完成后，以后可以用`docker restart <imageid>`或`docker start <imageid>`进行启动或者关闭
