DOC="A tiflash alive detect helper script.\
If tiflash is hanging, it receives the packets but doesn't respond. \
Dropping the packets will slow down the queries caused by the tidb \

This script checks the status port to detect whether TiFlash is hanging. \
Add a rule to iptables to REJECT the TCP packets once tiflash is hanging, \

I want to debug with CodeLLDB on CentOS 7, but get an error like this:

/home/xxx/.vscode/extensions/vadimcn.vscode-lldb-1.6.1/adapter/codelldb: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /home/xxx/.vscode/extensions/vadimcn.vscode-lldb-1.6.1/adapter/codelldb)

LLDB requires a higher version of glibc.

I get it work by the following steps:

github的多人协作

1. github上你可以用别人的现成的代码 直接 git clone 即可了

2. 然后你也想改代码或者贡献代码咋办？
