一：拉取Seata镜像

docker pull seataio/seata-server:1.4.2

二：运行Seata容器

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

2.1. 容器内目录拷贝到宿主机

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

2.2. 编辑 registry.conf 和 file.conf

[root@master01 resources]# pwd
/usr/local/home/docker/seata/seata-server/resources
[root@master01 resources]# ll
总用量 24
-rw-r--r-- 1 root root 1869 12月 23 01:53 file.conf
-rw-r--r-- 1 root root 3112 1月   1 1970 file.conf.example
drwxr-xr-x 3 root root   19 1月   1 1970 io
drwxr-xr-x 2 root root  114 1月   1 1970 logback

drwxr-xr-x 3 root root   22 1月   1 1970 META-INF
-rw-r--r-- 1 root root 1324 1月   1 1970 README.md
-rw-r--r-- 1 root root 1327 1月   1 1970 README-zh.md
-rw-r--r-- 1 root root 1982 12月 23 03:18 registry.conf

2. 2.1. 编辑注册中心相关文件

vim registry.conf

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"
	  }
  }

2.2.2. 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/seata-config"
    user = "****"
    password = "****"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

刚刚修改的是宿主机文件，但需注意即使是挂载目录进入容器相关修改的配置文件也不会生效

2.3. 宿主机文件拷贝至容器内部

docker cp /usr/local/home/docker/seata/seata-server/resources/registry.conf 16920a0fb6a5:/seata-server/resources/registry.conf

docker cp /usr/local/home/docker/seata/seata-server/resources/file.conf 16920a0fb6a5:/seata-server/resources/file.conf

三：Nacos注册中心相关配置操作

3.1 配置 seataServer.properties

填写：Data Id = seataServer.properties
GROUP = SEATA_GROUP
配置内容为：

3.2 重启seata服务 - > 看是否注入seata

3.3 没有注入 - > 进入容器查看配置文件

已经生效

[root@master01 resources]# docker exec -it 4d0f7460795d sh
/seata-server # ls
classes       libs          resources     sessionStore
/seata-server # cd resources/
/seata-server/resources # ls
META-INF           README.md          file.conf.example  logback            registry.conf
README-zh.md       file.conf          io                 logback.xml
/seata-server/resources # vi registry.conf

3.4 重启服务或刷新，在此查看，成功
