docker 运行 seata-server 配置nacos

服务端及源码下载地址：https://seata.apache.org/zh-cn

项目地址： https://github.com/seata/seata

项目官网： https://seata.io/zh-cn/docs/overview/what-is-seata.html

重要bug提示：seata at模式 每个库中的undo_log表的id一定删除掉，不然业务数据添加时返回的id会获取undo_log表中最新id设置到实体里面，1.4.2版本已经废弃id字段了

常见问题： https://seata.io/zh-cn/docs/overview/faq.html  问题10有说明

两个版本方式：

1、拉取镜像

docker pull seataio/seata-server:1.2.0

docker pull seataio/seata-server:1.3.0

docker pull seataio/seata-server:1.4.2

docker pull seataio/seata-server:1.5.2 #配置方式变成了application.yml方式

 

2、运行镜像

docker run --name seata-server -p 8091:8091 -d  seataio/seata-server:1.2.0

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

docker run --name seata1.4.2 -p 8091:8091 -d  seataio/seata-server:1.4.2

 

3、复制配置文件到主机

docker cp seata-server:/seata-server  /home/dockerdata/seata/seata-server

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

docker cp seata1.4.2:/seata-server  /home/dockerdata/seata1.4.2/seata-server

 

4、停止服务

docker stop seata-server

docker stop seata1.3.0

docker stop seata1.4.2

 

5、删除服务

docker rm seata-server

docker rm seata1.3.0

docker rm seata1.4.2

 

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  seata-server -p 8091:8091  -v /home/dockerdata/seata/seata-server:/seata-server -e SEATA_IP=172.168.1.35 -e SEATA_PORT=8091 seataio/seata-server:1.2.0 

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=172.168.1.35 -e SEATA_PORT=8091 seataio/seata-server:1.3.0 

docker run -d --restart always  --name  seata1.4.2 -p 8091:8091  -v /home/dockerdata/seata1.4.2/seata-server:/seata-server -e SEATA_IP=172.168.1.35 -e SEATA_PORT=8091 seataio/seata-server:1.4.2 

 

7、切换到seata配置目录

cd /home/dockerdata/seata/seata-server/resources

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

cd /home/dockerdata/seata1.4.2/seata-server/resources

 

8、修改registry.conf文件，修为nacos启用方式,绿色字体为修改的关键地方

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

  nacos {
    application = "seata-server"
    serverAddr = "172.168.1.35:8848"
    namespace = "89f54c6f-3b21-46a4-bd1b-242ae159c12e"
    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 = "file"

  nacos {
    serverAddr = "172.168.1.35:8848"
    namespace = "89f54c6f-3b21-46a4-bd1b-242ae159c12e"
    group = "DEFAULT_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"
  }
}

 

项目中的库需要执行，sql文件路径：https://github.com/seata/seata/tree/develop/script/client

seata服务 需要sql https://github.com/seata/seata/tree/develop/script/server

不用的模式执行不同的脚本

建议把sql中的lock_table表中的table_name字段长度改成64，不然某些表名太长会导致异常

具体的注意点查看/home/dockerdata/seata/resources/README-zh.md

9、修改file.conf存储方式为mysql

store {
  ## store mode: file、db
  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) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=false&serverTimezone=Asia/Shanghai"
    user = "root"
    password = "root"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

 

10、重启服务

docker restart seata-server
docker logs seata-server #查看启动日志

11、可以登录nacos查看服务列表，就会发现seata-server已经注册上来了
