1. docker 安装 mysql

	docker run -p 3315:3306 --name mysql5.7 \
	-v /usr/local/docker/mysql5.7/conf:/etc/mysql/mysql.conf.d \
	-v /usr/local/docker/mysql5.7/log:/var/log/ \
	-v /usr/local/docker/mysql5.7/data:/var/lib/mysql \
	-e MYSQL_ROOT_PASSWORD=123456 \
	-d mysql:5.7

2.docker安装nacos

docker run -d -p 8848:8848 \
--env MODE=standalone \
--env SPRING_DATASOURCE_PLATFORM=mysql \
--env MYSQL_SERVICE_HOST=101.43.236.92 \
--env MYSQL_SERVICE_PORT=3315 \
--env MYSQL_SERVICE_DB_NAME=nacos \
--env MYSQL_SERVICE_USER=root \
--env MYSQL_SERVICE_PASSWORD=123456 \
--restart=always \
--name nacos  nacos/nacos-server:1.4.1

3.docker 安装 seata 1.4.2

3.1 拉取镜像、启动服务、将容器文件拷贝到宿主机

docker pull seataio/seata-server:1.4.2
docker run -d --name seata-server -p 8091:8091 seataio/seata-server:1.4.2
docker cp seata-server:/seata-server  /xl/seata

3.2 修改 resource/registry.conf，重点修改nacos配置

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

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = "seata-dev"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }

......

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = "seata-dev"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
    dataId = "seataServer.properties"
  }
}

3.3 修改 resource/file.conf，重点修改 db 配置。

  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"
    ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
    url = "jdbc:mysql://101.43.236.92:3315/seata?rewriteBatchedStatements=true"
    user = "root"
    password = "123456"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

3.4 在Nacos 命名空间 seata-dev 上新增 seataServer.properties

3.5 删除原有容器，重新创建容器

docker stop seata-server
docker rm seata-server

docker run -d \
--restart always \
--name seata-server \
-p 8091:8091 \
-v /xl/seata/seata-server:/seata-server \
-e SEATA_IP=101.43.236.92 \
-e SEATA_PORT=8091 \
seataio/seata-server:1.4.2
