seata Adjusted frame length exceeds 8388608: 539959368，nacos+mysql+seata部署

本文主要是介绍seata Adjusted frame length exceeds 8388608: 539959368，nacos+mysql+seata部署，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

问题：docker 部署 seata 后出现异常

seata Adjusted frame length exceeds 8388608: 539959368

CSDN上找了一圈都解决不了。github又半天访问不上。后来终于访问上了，发现这是一个很离谱的问题。。。

原因：访问错了端口

seata默认分两个端口8091，7091，7091是网页访问的端口，8091是seata服务的端口，如果用网页访问，因为不支持http，所以会报这个错误

seata：部署步骤

1、启动一个容器

docker run -d --name seata seataio/seata-server

2、拷贝文件到外部方便修改

docker cp seata:/seata-server /usr/local/docker/seata/

3、删除旧容器

docker stop seata
docker rm seata

4、搭建好自己的mysql，nacos（这里就不详细说了）

5、mysql 创建seata数据库，运行数据库脚本

6、进入/usr/local/docker/seata/ 目录修改seata-server，拷贝application.example.yml为application.yml

cp application.example.yml application.yml

7、修改application.yml , seata.config

seata:
config:
# support: nacos 、 consul 、 apollo 、 zk 、 etcd3
type: nacos
nacos:
server-addr: #你的nacos地址（默认为127.0.0.1:8848）
namespace:
group: SEATA_GROUP
context-path:
##1.The following configuration is for the open source version of Nacos
username: #你的nacos用户名(默认为nacos)
password: #你的nacos密码(默认为nacos)
##2.The following configuration is for the MSE Nacos on aliyun
#access-key:
#secret-key:
##3.The following configuration is used to deploy on Aliyun ECS or ACK without authentication
#ram-role-name:
data-id: seataServer.properties

8、修改application.yml , seata.registry

registry:

# support: nacos 、 eureka 、 redis 、 zk 、 consul 、 etcd3 、 sofa

type: nacos

preferred-networks: 30.240.*

nacos:

application: seata-server

server-addr: #你的nacos地址（默认为127.0.0.1:8848

group: SEATA_GROUP

namespace:

cluster: default

context-path:

##1.The following configuration is for the open source version of Nacos

username: #你的nacos用户名(默认为nacos)

password: #你的nacos用户名(默认为nacos)

##2.The following configuration is for the MSE Nacos on aliyun

#access-key:

#secret-key:

##3.The following configuration is used to deploy on Aliyun ECS or ACK without authentication

#ram-role-name:

9、修改application.yml , store

store:

# support: file 、 db 、 redis 、 raft

mode: db

session:

mode: file

lock:

mode: file

file:

dir: sessionStore

max-branch-session-size: 16384

max-global-session-size: 512

file-write-buffer-cache-size: 16384

session-reload-read-size: 100

flush-disk-mode: async

db:

datasource: druid

db-type: mysql

driver-class-name: com.mysql.jdbc.Driver

url: jdbc:mysql://IP:3306/seata?rewriteBatchedStatements=true

user: #数据库用户

password: #数据库密码

min-conn: 10

max-conn: 100

global-table: global_table

branch-table: branch_table

lock-table: lock_table

distributed-lock-table: distributed_lock

query-limit: 1000

max-wait: 5000

10、application.yml 的最后加上store.security、console配置

security:
secretKey: "key"
tokenValidityInMilliseconds: 1000000
console:
user:
username: #你想的用户名
password: #你想一个密码

11、启动seata

docker run -d --restart always --name seata -p 8091:8091 -p 7091:7091 -v /usr/local/docker/seata/seata-server/:/seata-server -e SEATA_PORT=8091 seataio/seata-server
