一般容易忘比如云服务器安全组的开放
docker ps 查看运行中的容器

报错信息是netty 解码大小相关，百度上搜了一下有说是版本号的，也有说是没有注册到nacos相关原因；
宿主机相关配置检查了一下是没问题的;
然后到容器里查看配置,如下；
发现并没有生效，估计是中间运行了几次容器，容器挂载目录可能失效了，手动修改一下:
registry和file配置文件
[root@VM-12-7-centos resources]# docker exec -it 406794a01181 /bin/sh
/seata-server # ls
classes libs resources sessionStore
/seata-server # cd resources/
/seata-server/resources # ks
/bin/sh: ks: not found
/seata-server/resources # ks
/bin/sh: ks: not found
/seata-server/resources # ls
META-INF README-zh.md README.md file.conf file.conf.example io logback logback.xml registry.conf
/seata-server/resources # vi registry.conf
registry {
# file ...nacos ...eureka...redis...zk...consul...etcd3...sofa
type = "file"
nacos {
application = "seata-server"
保存重启seata和nacos服务，查看日志和nacos客户端，已经有了刚刚的服务
docker pull seataio/seata-server:1.4.2二：创建Seata容器并指定挂载目录
docker run -d --restart always --name seata-server -p 8091:8091 -v /docker-data/seata:/seata-server -e SEATA_IP=IP-ADDRESS -e SEATA_IP=101.****.62 -e SEATA_PORT=8091 seataio/seata-server:1.4.2 docker run -d --restart always --name seata-server -p 8091:8091 -v /docker-data/seata:/seata-server -e SEATA_IP=101.****.62 -e SEATA_PORT=8091 seataio/seata-server:1.4.2三：拉取Nacos镜像
docker pull nacos/nacos-server -----拉取nacos镜像四：创建Nacos容器
大致能运行打开; docker run --name nacos -d -p 8848:8848 --privileged=true --restart=always -e JVM_XMS=256m -e JVM_XMX=256m -e MODE=standalone -e PREFER_HOST_MODE=hostname nacos/nacos-server五：创建Seata相关表

编辑配置相关文件 vim registry.conf 编辑以下两部分: 注册中心相关指向；
registry {
type = "nacos"
nacos {
# 应用名
application = "seata-server"
# nacos ip 地址
serverAddr = "101.****:8848"
# nacos创建的分组
group = "SEATA_GROUP"
# nacos 创建的命名空间名
namespace = "seata-naming"
cluster = "default"
# nacos登录的账号和密码
username = "nacos"
password = "nacos"
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "nacos"
nacos {
# nacos ip 地址
serverAddr = "101.****:8848"
# nacos 创建的命名空间名
namespace = "seata-naming"
# nacos创建的分组
group = "SEATA_GROUP"
# nacos登录的账号和密码
username = "nacos"
password = "nacos"
# nacos配置相当于主键id，唯一标识配置
dataId = "seataServer.properties"
}
file {
name = "file.conf"
}
}
编辑Seata存储数据的相关配置文件 vim file.conf; 这里面连接的库就是上面执行脚本的库;
## transaction log store, only used in seata-server
store {
## store mode: file、db、redis
mode = "db"
## 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.cn.jdbc.Driver"
## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
url = "jdbc:mysql://182.****:3307/order-info"
user = "****"
password = "****"
minConn = 5
maxConn = 100
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
maxWait = 5000
}
}
七：进入Nacos配置Seata相关信息
根据上一步注释可以看到需要修改补充哪些字段属性；
先在配置管理里面进行相应操作：
填写：Data Id = seataServer.properties
GROUP = SEATA_GROUP

创建命名空间:
用于后面区分唯一服务和配置 ->
命名空间ID(不填则自动生成)：seata-naming
命名空间名：seata
描述：desc
docker stop seata-container-id 停掉
docker start seata-container-id 开启
docker ps 查看运行中的容器
docker logs containerid 启动打印日志
我遇到的问题放到了开头 第0点
