用docker部署springCloud环境全家桶

docker部署

步骤一：安装docker

yum install  -y  yum-utils

设置更新docker镜像源
yum-config-manager --add-repo  https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker镜像

yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

启动命令

systemctl start docker

设置开机自动启动

systemctl enable docker

步骤二：配置docker镜像源

创建文件夹

mkdir -p /etc/docker

进入docker目录

cd /etc/docker

创建daemon.json文件

touch daemon.json  

步骤三：书写配置信息

{
  "registry-mirrors": [
    "https://docker.m.daocloud.io",
    "https://docker.imgdb.de",
    "https://docker-0.unsee.tech",
    "https://docker.hlmirror.com",
    "https://docker.1ms.run",
    "https://func.ink",
    "https://lispy.org",
    "https://docker.xiaogenban1993.com"
  ]
}

步骤四：重载配置信息

systemctl daemon-reload

systemctl restart docker

docker run -d -p 3306:3306 --name mysql --restart=always --privileged=true -e TZ=Asia/Shanghai -e MYSQL_ROOT_PASSWORD=root  mysql:8.0

步骤二：修改MySQL密码

docker exec -it   容器名/容器id bash

mysql -uroot -proot

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root'

seate部署 

步骤一：安装seate

docker pull seataio/seata-server:2.0.0

mkdir -p /opt/seata/config

docker run -d -p 8091:8091 -p 7091:7091  --name seata-server seataio/seata-server:2.0.0

docker cp seata-server:/seata-server/resources/. /opt/seata/config

步骤二：更改配置

1.修改application.example.yml中的配置信息（用db模式，并配置连接信息）

2.配置file.conf，如下(注意修改ip)：

transport {
  # TCP 通信端口
  type = "TCP"
  server = "NIO"
  heartbeat = true
  enable-client-batch-send-request = true
  thread-factory {
    boss-thread-prefix = "NettyBoss"
    worker-thread-prefix = "NettyServerNIOWorker"
    server-executor-thread-prefix = "NettyServerBizHandler"
    share-boss-worker = false
    client-selector-thread-prefix = "NettyClientSelector"
    client-selector-thread-size = 1
    client-worker-thread-prefix = "NettyClientWorkerThread"
    worker-thread-size = default
    boss-thread-size = 1
  }
  shutdown {
    wait = 3
  }
}

service {
  # 事务组映射配置
  vgroupMapping.default_tx_group = "default"
  default.grouplist = "ip:8091"
  enableDegrade = false
  disableGlobalTransaction = false
}

client {
  rm {
    asyncCommitBufferLimit = 10000
    lock {
      retryInterval = 10
      retryTimes = 30
      retryPolicyBranchRollbackOnConflict = true
    }
    reportRetryCount = 5
    tableMetaCheckEnable = false
    reportSuccessEnable = false
  }
  tm {
    commitRetryCount = 5
    rollbackRetryCount = 5
  }
}

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

  ## file store property
  file {
    dir = "sessionStore"
    maxBranchSessionSize = 16384
    maxGlobalSessionSize = 512
    fileWriteBufferCacheSize = 16384
    sessionReloadReadSize = 100
    flushDiskMode = true
  }

  ## database store property
  db {
    datasource = "druid"
    dbType = "mysql"
    driverClassName = "com.mysql.cj.jdbc.Driver"
    url = "jdbc:mysql://ip:3306/seata?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&useSSL=false"
    user = "root"
    password = "root"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

3.配置registry.conf信息

registry {
  # 注册中心类型：支持 nacos, eureka, redis, zk, consul, etcd3, sofa
  type = "nacos"

  nacos {
    application = "seata-server"  # Seata Server 在注册中心中的服务名称
    serverAddr = "ip:8848"  # Nacos 服务器地址
    group = "SEATA_GROUP"  # 分组名称
    namespace = "d201079a-a6fb-4f5e-a5d6-3300329baa87"  # 命名空间（可选）
    cluster = "default"  # 集群名称
    username = "qgy"  # Nacos 用户名（如果有）
    password = "qgy"  # Nacos 密码（如果有）
  }
}

config {
  # 配置中心类型：支持 nacos, consul, apollo, zk, etcd3
  type = "nacos"

  nacos {
    serverAddr = "ip:8848"  # Nacos 服务器地址
    group = "SEATA_GROUP"  # 分组名称
    namespace = "d201079a-a6fb-4f5e-a5d6-3300329baa87"  # 命名空间（可选）
    username = "qgy"  # Nacos 用户名（如果有）
    password = "qgy"  # Nacos 密码（如果有）
    dataId = "seataServer.properties"  # 配置文件的 Data ID
  }
}

4.在MySQL进行表的基本配置

-- 1. 执行语句创建名为 seata 的数据库
CREATE DATABASE seata DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;

-- 2.执行脚本完成 Seata 表结构的创建
USE seata;

-- https://github.com/seata/seata/blob/1.7.1/script/server/db/mysql.sql
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,
    `application_id`            VARCHAR(32),
    `transaction_service_group` VARCHAR(32),
    `transaction_name`          VARCHAR(128),
    `timeout`                   INT,
    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_status_gmt_modified` (`status` , `gmt_modified`),
    KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = INNODB
  DEFAULT CHARSET = utf8mb4;

-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
    `branch_id`         BIGINT       NOT NULL,
    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,
    `client_id`         VARCHAR(64),
    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = INNODB
  DEFAULT CHARSET = utf8mb4;

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(128),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),
    `table_name`     VARCHAR(32),
    `pk`             VARCHAR(36),
    `status`         TINYINT      NOT NULL DEFAULT '0' COMMENT '0:locked ,1:rollbacking',
    `gmt_create`     DATETIME,
    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_status` (`status`),
    KEY `idx_branch_id` (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = INNODB
  DEFAULT CHARSET = utf8mb4;

CREATE TABLE IF NOT EXISTS `distributed_lock`
(
    `lock_key`       CHAR(20) NOT NULL,
    `lock_value`     VARCHAR(20) NOT NULL,
    `expire`         BIGINT,
    PRIMARY KEY (`lock_key`)
) ENGINE = INNODB
  DEFAULT CHARSET = utf8mb4;

INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);

5.在使用的模块所在数据库中加入表

USE learndemo;

CREATE TABLE IF NOT EXISTS `undo_log` (
  `id` BIGINT(20) NOT NULL AUTO_INCREMENT,
  `branch_id` BIGINT(20) NOT NULL,
  `xid` VARCHAR(100) NOT NULL,
  `context` VARCHAR(128) NOT NULL,
  `rollback_info` LONGBLOB NOT NULL,
  `log_status` INT(11) NOT NULL,
  `log_created` DATETIME NOT NULL,
  `log_modified` DATETIME NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

 注意：配置好了记得重启

sentinel配置
