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.
