关键错误

TCP/IP, --shared-memory, or --named-pipe should be configured on NT OS

解决方案

修改my.ini,添加shared-memory

这个问题是由于我的MySQL的的的更新至8版本以上了，在安装的时候我并没有指定用户登入密码加密方式，所以默认被设置为caching_sha2_password
解决方法：

mysql> show variables like 'default_authentication_plugin';

查看本地mysql用户的信息

mysql> select host,user,plugin from mysql.user;

注意 caching_sha2_password， 只修改root的密码加密方式就可以了

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

mysql> select host,user,plugin from mysql.user;

使用tdm-gcc
https://jmeubank.github.io/tdm-gcc/download/
然后再系统环境变量path里把tdragon的位置上移到cygwin上面，
让系统调用gcc时先识别tdragon的gcc，或者直接把cygwin的环境路径直接删除了，
或者直接从goland里的settings->Go->GoPath里添加tdragon的路径，如下图

EOS 编译Debug

./scripts/eosio_build.sh -o Debug

ubuntu设置coredump

sudo sysctl -w kernel.core_pattern=/corefiles/core.%p.%e
sudo mkdir /corefiles
sudo chmod -R 777 /corefiles
ulimit -c unlimited

当nodeos异常退出时，就会在/corefiles/生成dump文件

查看插件返回(github)

 rm.get_account_limits( result.account_name, result.ram_quota, result.net_weight, result.cpu_weight );

查看资源设置(github)

set_resource_limits( res_itr->owner, res_itr->ram_bytes + ram_gift_bytes, net, cpu );

结论

ram_bytes是实际买的RAM 大小，ram_quota 是加上了 赠送的ram_gift_bytes（等于1400）(github)

验证

cleos -u https://api.eoslaomao.com get account bcskillsurou

返回

memory:
     quota:     4.348 KiB    used:      3.49 KiB

查看账户资源表

cleos -u https://api.eoslaomao.com get table eosio bcskillsurou userres

返回

{
  "rows": [{
      "owner": "bcskillsurou",
      "net_weight": "0.0046 EOS",
      "cpu_weight": "0.0147 EOS",
      "ram_bytes": 3052
    }
  ],
  "more": false,
  "next_key": ""
}

计算
quota 与 ram_bytes差值等于 1400，与ram_gift_bytes值一致。
