# docker部署seata server
https://seata.io/zh-cn/docs/ops/deploy-by-docker.html

这里以1.4.1版本为例：
1. 启动seata-server实例
```
docker run -d --name seata-server -p 8091:8091 seataio/seata-server:1.4.1
```
2. 把相关文件拷到宿主机，主要包含三个文件夹：classes、libs、resources
```
docker cp 1ba061641b3b:/seata-server/classes /data/dockerdata/seata/seata-server-141
docker cp 1ba061641b3b:/seata-server/libs /data/dockerdata/seata/seata-server-141
docker cp 1ba061641b3b:/seata-server/resources /data/dockerdata/seata/seata-server-141
```
3. 修改相关配置，配置文件在resources下，修改的文件为registry.conf和file.conf，删除原容器准备重建seata-server容器
参考配置：
##### registry.conf

```
registry {
  type = "nacos"
  loadBalance = "RandomLoadBalance"
  loadBalanceVirtualNodes = 10

nacos {
    application = "seata-server"
    serverAddr = "192.168.10.xx:8848"
    group = "SEATA_GROUP"
    namespace = "public"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }

file {
    name = "file.conf"
  }
}

config {
  type = "nacos"
  nacos {
    serverAddr = "192.168.10.xx:8848"
    namespace = "public"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }

file {
    name = "file.conf"
  }
}
```
##### file.conf

```
store {
    mode = "db"
  ## rsa decryption public key
  publicKey = ""
  ## 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 {
    datasource = "druid"
    dbType = "mysql"
    driverClassName = "com.mysql.cj.jdbc.Driver"
    url = "jdbc:mysql://192.168.10.xxx:3309/test?rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai"
    user = "xx"
    password = "xxx"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}
```

#### 启动seata-server并挂载配置文件到宿主机
```
docker run -d --name seata-server \
        -p 8091:8091 \
        -e SEATA_CONFIG_NAME=file:/seata-server/resources/registry -e SEATA_IP=172.16.27.72 \
		-v /etc/localtime:/etc/localtime:ro \
        -v /data/dockerdata/seata/seata-server-141:/seata-server -v /data/logs/seata:/root/logs/seata \
        seataio/seata-server:1.4.1
```
注意：
```
# 让容器使用系统时区
-v /etc/localtime:/etc/localtime:ro
```
##### 此时可以去nacos查看是否有seata-server的可用服务
