概述
NodeCore是运行VBK区块链的服务。 它采用Java编写，可以在Windows，Linux和Mac上运行。
要查看安装NodeCore的操作指南，请参阅：NodeCore_Operations
步骤
解开压缩包：
| Windows | Mac 和 Linux |
|---|---|
| 解压缩nodecore-*.zip文件到bin文件夹中，然后运行nodecore.bat | 解压缩到首选目录，然后运行nodecore。
注意：在Linux和Mac系统上，您可能需要通过运行以下命令来让nodecore shell脚本可执行： chmod a+x nodecore |
当您第一次运行NodeCore时，它将在新的testnet文件夹（nodecore.properties，veriblock.nodecore.log，nodecore.dat等）中创建其他几个文件，并加载现有的区块链文件。
NodeCore可能需要几分钟才能加载区块链中的所有块。 请参阅https://TestNet.Explore.Veriblock.org上的当前最高区块。 这显示了本地NodeCore必须加载的块数。 NodeCore将创建一个缓存文件，以便在重新启动程序时，下次加载的速度更快。
FAQ
为什么区块时间的值为负？
时间为负说明矿工的时钟超前了。

如何在升级NodeCore的同时保留钱包
由于当前是一个测试网络，将更为频繁的发布新版本的NodeCore。 因为更新进程较快。
如果您没有以前的钱包/地址/余额，那么操作很简单，只需下载并运行新的NodeCore即可。
如果您有要继续使用的钱包/地址/余额需要迁移，这仍然很容易，只需确保执行以下操作：
- 确保您有钱包的备份！ 您可以复制testnet文件夹，或使用NC_CLI中的NodeCore_CommandLine#importwallet命令。
- 将NodeCore解压缩到新的文件夹位置，请注意不要覆盖以前的版本。
- 在新版本中：
- 创建一个testnet文件夹（一般在“nodecore-0.X.X \ bin”中）
- 将之前的wallet.dat和walletconfig.dat文件复制到“nodecore-0.X.X\bin\testnet”中。
- 当您在新版本上运行NC_CLI getinfo命令时，您应该可以看到之前的钱包和余额。
如何升级NodeCore PoW并保留比特币testnet钱包
When upgrading your PoP miner, you can copy the file "bitcoin-pop-testnet.wallet" from the bin folder of your current PoP miner directory to the bin folder of your new PoP miner.
How to specify a data directory for NodeCore
NodeCore can take a data directory ~d as part of the startup.
Example for Linux:
cd /<myDir>/nodecore-0.1.7/bin ./nodecore -d ~/data/ > /dev/null 2>&1 &
- nodecore.properties will be in ~/data/nodecore.properties
- /testnet folder will be in ~/data/testnet
Example for Windows
cd <myDir>\nodecore-0.2.1-r2\bin nodecore.bat -d C:\data # nodecore.properties will be in C:\data\nodecore.properties # /testnet folder will be in C:\data\testnet
How to send from a specific address?
As of 7/18/2018, the send command only sends from the default address, there is not a public way to select the address.
A workaround is to call the setdefaultaddress (see: NodeCore_CommandLine#setdefaultaddress )
Then 'send' will use that new address.
Troubleshooting
NodeCore is stuck on a block
Ideally this should not happen, but if it does first try restarting NodeCore.
Java out-of-memory
It is possible that you only have a 32-bit version of Java installed. 64-bit is highly recommended.
Modify the start file (nodecore.bat for windows, nodecore for linux) to increase the memory limit. Pass in a value, such as "1024 MB" into the DEFAULT_JVM_OPTS variable:
DEFAULT_JVM_OPTS=-Xmx1024m
NodeCore keeps turning off with "Application exit"
If messages like:
INFO [main] n.Program [Program.java:133] Application exit
Then something external is shutting off NodeCore (such as a server restart, external process kill, or something else).
Having trouble on a mac
On a Mac, you need to install the JDK (Java Development Kit) instead of just the JRE: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
