seata 启动报错 the {store.db.driver-class-name} can't be empty

[jarvisqi]

Version：1.0.0 ，Seata 启动报错 the {store.db.driver-class-name} can't be empty ，

registry.conf 文件 如下

`
registry {
type = "nacos"
nacos {
serverAddr = "10.10.10.10:8849"
namespace = ""
cluster = "default"
}
}
config {
type = "nacos"
nacos {
serverAddr = "10.10.10.10:8849"
namespace = ""
}
}

`

file.conf 文件 如下

Environment:

• JDK version : 1.8
• OS : CentOS 7.5

registry.conf 中config的type=“nacos“改成type=”file“试试

[usench]

这个问题我也遇到了，我用的是type="nacos",因此file.conf 这个配置文件是不起作用的（@jarvisqi )；
简单写下我解决的步骤；
我的环境：
OS: ubuntu 18.04 LTS
JDK version: 1.8
nacos server version: nacos-server-1.1.4
seata server version:seata-server-1.0.0

• 将nacos server 跑起来；
• [ ] 进入 nacos conf 目录：

1. 将cluster.conf.example 修改cluster.conf ,你安装了几个nacos （集群）,这里就填nacos 所在机子ip; 我只有一个，所以填本机ip：

it is ip

example

192.168.1.150

1. application.properties里添加以下几行数据库配置信息：

db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3366/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=usench1
db.password=123456

1. 执行nacos-mysql.sql，前提是先创建nacos_config 数据库；

2. 执行bin 目录 下的startup.sh:

bash startup.sh   (centos 下，直接sh startup.sh )
usench1@usench-computer:~/workspace/my-study/seata/nacos-server/bin$ bash startup.sh 
/home/usench1/app/jdk/jdk1.8.0_181/bin/java  -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/home/usench1/workspace/my-study/seata/nacos-server/logs/java_heapdump.hprof -XX:-UseLargePages -Djava.ext.dirs=/home/usench1/app/jdk/jdk1.8.0_181/jre/lib/ext:/home/usench1/app/jdk/jdk1.8.0_181/lib/ext:/home/usench1/workspace/my-study/seata/nacos-server/plugins/cmdb:/home/usench1/workspace/my-study/seata/nacos-server/plugins/mysql -Xloggc:/home/usench1/workspace/my-study/seata/nacos-server/logs/nacos_gc.log -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=100M -Dnacos.home=/home/usench1/workspace/my-study/seata/nacos-server -Dloader.path=/home/usench1/workspace/my-study/seata/nacos-server/plugins/health -jar /home/usench1/workspace/my-study/seata/nacos-server/target/nacos-server.jar  --spring.config.location=classpath:/,classpath:/config/,file:./,file:./config/,file:/home/usench1/workspace/my-study/seata/nacos-server/conf/ --logging.config=/home/usench1/workspace/my-study/seata/nacos-server/conf/nacos-logback.xml --server.max-http-header-size=524288
nacos is starting with cluster
nacos is starting，you can check the /home/usench1/workspace/my-study/seata/nacos-server/logs/start.out
usench1@usench-computer:~/workspace/my-study/seata/nacos-server/bin$

1. 访问nacos,http://127.0.0.1:8848/nacos/#/login ,用户名:nacos,密码:nacos,成功进入,至此，nacos server 就算是完成了；

• 将seata server 跑起来

• [ ] 进入seata conf 目录

1. 将registry.conf 修改如下：

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

  nacos {
    serverAddr = "192.168.1.150"
    namespace = ""
    cluster = "default"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "192.168.1.150"
    namespace = ""
  }
}

注意点：namespace 填 命名空间ID ，我的public 命名空间ID 是空；serverAddr 是nacos 机子ip;

1. 将seata github 代码里的config.txt (seata/script/config-center/config.txt)下载下来，放到本地seata server 的bin 目录下，修改里面的数据库配置信息(store.db.* 相关)；

1. 在seata server 的bin 目录下创建nacos-config.sh，内容如下：

1. 执行nacos-conf.sh, 注：先保证nacos server 已启动成功；执行完脚本后，登录nacos web 就可以看见新添加的参数了(在public 空间)；脚本是我修改过的，脚本默认是在public 空间里添加参数，如果想在自己创建的空间下添加配置呢？有知道的请告知，不过nacos web 里有个克隆按钮；

出现问题：
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'seata.global_table' doesn't exist
解决： 到seata github 源码里：seata/script/server/db/mysql.sql，在seata 数据库中执行即可；

到此，seata server 与 nacos server 成功启动；

@usench very patient and kind answer.
@jarvisqi have you solved the problem? The point is that there are "store.db.driver-class-name" configuration items in the nacos configuration center?
