brew is a bad neighbor

This isn't a guide about locking down homebrew so that it can't touch the rest of your system security-wise.

This guide doesn't fix the inherent security issues of a package management system that will literally yell at you if you try to do something about "huh, maybe it's not great my executables are writeable by my account without requiring authorization first".

But it absolutely is a guide about shoving it into its own little corner so that you can take it or leave it as you see fit, instead of just letting the project do what it likes like completely taking over permissions and ownership of a directory that might be in use by other software on your Mac and stomping all over their contents.

By following this guide you will:

• Never have to run sudo to forcefully change permissions of some directory to be owned by your account

mTLS 配置

对于mTLS的配置的证书来说，有如下的提示。

• 三个文件。 对于大多数系统，如：MySQL, Redis，PostgreSQL。会需要三个文件：CA证书 + CERT 和 KEY。可以在我的这个开源项目（https://github.com/haoel/mTLS/tree/main/certs ）中找到我生成的CA，以及 Server 和 Client的 .crt 和 .key 文件。生成的方法也在我的那个开源项目中了。

• 两个文件。 对于有的系统，比如：MongoDB，他只要两个文件，一个是CA，一个是 pem 文件，对于pem文件，你可以直接把上面的 .crt 和 .key 合并了就好了。如：cat server.crt server.key > server.pem

• JKS文件。 对于一些系统，比如：Kafka 和 Zookeeper。他要的不是上面的明文的格式，他要的是一种jks的格式，这是Java的格式。怎么从上面的明文的方式转到jks的文件。需要经过下面几步。

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).
