安装openssl使不执行mv /usr/bin/openssl /usr/bin/openssl.bak会出问题吗?

在安装 OpenSSL 的过程中执行 `mv /usr/bin/openssl /usr/bin/openssl.bak` 命令会将系统原本的 OpenSSL 命令备份为 `openssl.bak`,然后再将新的 OpenSSL 命令放到 `/usr/bin/openssl` 中。如果在这个过程中出现问题,可能会导致 OpenSSL 命令无法正常工作,从而影响到系统的正常运行。
因此,在执行这个命令之前,建议先备份系统原本的 OpenSSL 命令,并确保备份的文件名与路径没有被其他程序使用。另外,也可以先在测试环境中进行安装和测试,确保安装过程不会影响到系统的正常运行。

在执行make && make install之前先执行mv /usr/bin/openssl /usr/bin/openssl.bak会报错吗?
执行 `mv /usr/bin/openssl /usr/bin/openssl.bak` 会将 `/usr/bin/openssl` 文件重命名为 `/usr/bin/openssl.bak`,如果 `/usr/bin/openssl` 是一个有效的文件,则执行 `make && make install` 时可能会报错,因为编译器需要 `/usr/bin/openssl` 文件。如果你已经备份了 `/usr/bin/openssl` 文件,可以先执行 `make && make install`,如果编译器需要 `/usr/bin/openssl` 文件时出现问题,再将备份的 `/usr/bin/openssl.bak` 文件重命名为 `/usr/bin/openssl`。
/usr/local/Cellar/openssl@1.1/./1.1.1t: Permission denied
This error message indicates that you do not have permission to access the specified directory or file. It is possible that the file or directory has restricted permissions, or that you are not logged in as a user with sufficient privileges to access it.
To resolve this issue, you can try the following steps:
1. Check the permissions of the file or directory: Run the command `ls -l /usr/local/Cellar/openssl@1.1/./1.1.1t` to see the permissions of the file or directory. If the permissions are set to read-only or restricted, you may need to change them using the `chmod` command.
2. Run the command with elevated privileges: If you are not logged in as a user with sufficient privileges to access the file or directory, try running the command with `sudo` to elevate your privileges.
3. Check for file system errors: If the issue persists, it is possible that there are errors on your file system that are preventing you from accessing the file or directory. You can run the `fsck` command to check for and repair any errors on your file system.
If none of these steps resolve the issue, you may need to seek assistance from a system administrator or technical support.
