最少需要RAM 3kb,具体等于多少EOS需要根据当前RAM的价格来定

EOS enable mongodb

 2018-07-05　  Surou　  阅读 　  EOS-新手问答　  0 评论 
git clone -b release/1.1 https://github.com/EOSIO/eos.git
cd eos
git fetch –all –tags –prune
git merge -m “merge” –commit origin/gh#3030-enable-mongodb
git submodule update –init –recursive
./eosio_build.sh
cd build
make install

修改config.ini配置文件，添加如下两行：

plugin = eosio::mongo_db_plugin
mongodb-uri = mongodb://localhost:27017/eosmain

其中，eosmain是要写入的MongoDB数据库名。
好了，万事俱备，开始启动
进入~/opt/mongodb/bin目录，启动MongoDB服务。

cd ~/opt/mongodb/bin
./mongod

这时MongoDB服务会默认监听27017端口，如下图所示。

新开一个小窗，重启nodeos，需要加上–replay-blockchain，以使历史交易数据同步到MongoDB。
如果没有意外的话，此时MongoDB应该开始写入相关记录了。
执行mongo程序进入MongoDB控制台，查询相应数据库和记录，如下图。

boost::interprocess::bad_alloc

 2018-07-05　  Surou　  阅读 　  EOS-新手问答　  0 评论

由于解决 cleos get transaction 返回空的信息
此问题，导致运行 nodeos 提示以下错误

terminate called after throwing an instance of 'boost::interprocess::bad_alloc'
  what():  boost::interprocess::bad_alloc

解决方案：修改 config.ini 中 chain-state-db-size-mb调大些，默认1024，一般改为2048即可，当然服务器内存较大可以再多分些。
参考：github issues

EOS节点开启RPC访问

修改 config.ini

  1. access-control-allow-origin = * //解决跨域问题
  2. http-server-address = 0.0.0.0:8888 //接受任何IP的访问

cleos get transaction 返回空的信息

修改 config.ini中filter-on = * 或者 nodeos启动时添加参数--filter-on "*"
重新发起transaction获取新的transaction_id。之前旧的transaction_id无法获取
