• Dawn = Alpha
• V1.. = Beta
• EOS Mainnet 版本 = Stable

Alpha：是内部测试版,一般不向外部发布,会有很多Bug.一般只有测试人员使用。Beta：也是测试版，这个阶段的版本会一直加入新的功能。在Alpha版之后推出。Stable：稳定版；来自预览版本释出使用与改善而修正完成。

更新 ~/.local/share/eosio/nodeos/config/config.ini
修改或添加
http-validate-host=false

或者 nodeos 启动时添加参数 --http-validate-host=false

kill 命令再次执行时会导致以下错误。

pkill -9 nodeos or kill -9 {pid}
database dirty flag set (likely due to unclean shutdown): replay required

当重新运行nodeos时，必须使用--replay-blockchain命令忽略它。

让我们安全的结束nodeos 进程

This appears to be two different issues.

Startup after a crash or ungraceful shutdown nearly always fails due to corruption of the boost shared memory cache of the in-memory database. --resync is required to clean up the mess.

For normal shutdown, never kill with -9. Always use either the default (no argument) signal (which is SIGTERM) or SIGINT. Numerically, those are 15 and 2, respectively.

pkill nodeos | Safe
pkill -15 nodeos | Safe
pkill -2 nodeos | Safe
pkill -TERM nodeos | Safe
pkill -SIGTERM nodeos | Safe
pkill -INT nodeos | Safe
pkill -SIGINT nodeos | Safe
pkill -9 nodeos | Not Safe
pkill -KILL nodeos | Not Safe
pkill -SIGKILL nodeos | Not Safe

The core dump is a different problem. That looks like a corrupted network packet, specifically a signed_block_summary. Summary messages are being eliminated from the protocol, so this particular error will no longer be possible soon.

新手第一次编译EOS后执行编译Hello World合约时经常出现如下错误

root@ubuntu:~/eos/build/tools# ./eosiocpp -o ../contracts/hello/hello.wast ../contracts/hello/hello.cpp 
../hello/hello.cpp:3:10: fatal error: 'eosiolib/eosio.hpp' file not found #include ^~~~~~~~~~~~~~~~~~~~ 1 error generated.
root@ubuntu:~/eos/build/tools#

解决此问题方案如下

1. cd eos_source/build,执行 sudo make install
2. cd ../contracts/hello/ 切换到hello 合约目录
3. 去掉执行程序eosiocpp前的./，修改为 eosiocpp -o hello.wast hello.cpp

v1.1.0 之后版本 出现的问题 参考（更新v1.1.0后，在执行 sudo make install 之后，cleos 等指令还是无效）

添加环境变量

打开 ~/.bashrc

vi ~/.bashrc

在文件最后添加

#set eosio path
export EOSIO_PATH=/usr/local/eosio/bin
export PATH=$EOSIO_PATH:$PATH

终端执行以下命令，添加立即生效

source ~/.bashrc
