seata docker 连接nacos

1.拉取镜像

docker pull seataio/seata-server:1.3.0

2.运行镜像

docker run --name seata1.3.0 -p 8091:8091 -d  seataio/seata-server:1.3.0

3.复制配置文件到主机

docker cp seata1.3.0:/seata-server  /home/dockerdata/seata1.3.0

4.停止服务

docker stop seata1.3.0

5.删除服务

docker rm seata1.3.0

6.重新运行服务，至此服务已经启动完成，接下来就是在/home/dockerdata/seata/seata-server目录中修改对应的配置（设置开机自启和关键配置挂载到本地目录方便修改配置）

docker run -d --restart always  --name  seata1.3.0 -p 8091:8091  -v /home/dockerdata/seata1.3.0/seata-server:/seata-server -e SEATA_IP=192.168.1.128 -e SEATA_PORT=8091 seataio/seata-server:1.3.0

1.4.0版本

docker run -d --restart always  --name  seata1.4.0 -p 8092:8091  -v /home/dockerdata/seata1.4.0:/seata-server -e SEATA_IP=192.168.0.159 -e SEATA_PORT=8091 seataio/seata-server:1.4.0

7.切换到seata配置目录 (如果没有目录 mkdir -p 创建目录)

cd /home/dockerdata/seata1.3.0/seata-server/resources

8.修改registry.conf文件，修为nacos启用方式

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "192.168.1.128:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = ""
    password = ""
  }
  eureka {
    serviceUrl = "http://localhost:8761/eureka"
    application = "default"
    weight = "1"
  }
  redis {
    serverAddr = "localhost:6379"
    db = 0
    password = ""
    cluster = "default"
    timeout = 0
  }
  zk {
    cluster = "default"
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
  consul {
    cluster = "default"
    serverAddr = "127.0.0.1:8500"
  }
  etcd3 {
    cluster = "default"
    serverAddr = "http://localhost:2379"
  }
  sofa {
    serverAddr = "127.0.0.1:9603"
    application = "default"
    region = "DEFAULT_ZONE"
    datacenter = "DefaultDataCenter"
    cluster = "default"
    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {
    name = "file.conf"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "192.168.1.128:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = ""
    password = ""
  }
  consul {
    serverAddr = "127.0.0.1:8500"
  }
  apollo {
    appId = "seata-server"
    apolloMeta = "http://192.168.1.204:8801"
    namespace = "application"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

9.修改数据库配置  file.conf

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db"

  ## 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"
    url = "jdbc:mysql://自己得ip:自己端口/seata"
    user = "自己数据库账号"
    password = "自己数据库密码"
    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
  }

}

10.执行推送nacos配置文件 nacos-config.sh   config.txt

sh nacos-config.sh -h 192.168.1.128 -p 8848 -g SEATA_GROUP -t  seata -u nacos -w nacos

上面命令得-t后面为nacos配置命名空间id

touch nacos-config.sh
