如何升级Mac中自带的openssl ?下面这篇文章就给大家介绍关于Mac中自带的openssl升级过程,有需要的可以参考一下。
由于Mac自带的 openssl
太老了,所以,这里因为安装python扩展包需要升级到高版本,所以,总结下升级过程。
一、安装openssl
首先,来看看我们的openssl 的版本和目录:
-> ~ openssl version OpenSSL 0.9.8zh 14 Jan 2016 -> ~ which openssl /usr/bin/openssl -> ~
通过上面的查看,明显我们的版本号太低了。
按照上面的步骤,我们首先更新homebrew
brew update
安装:
brew install openssl # 重新安装 # brew reinstall openssl
安装成功后:
~ brew reinstall openssl ==> Reinstalling openssl ==> Downloading https://homebrew.bintray.com/bottles/openssl-1.0.2p.el_capitan.bottle.tar.gz Already downloaded: /Users/kaiyiwang/Library/Caches/Homebrew/downloads/96bc2acd84d0fe609dcbe4c6436c864808f7e8f26f2f12111f552f5972c3840a--openssl-1.0.2p.el_capitan.bottle.tar.gz ==> Pouring openssl-1.0.2p.el_capitan.bottle.tar.gz ==> Caveats A CA file has been bootstrapped using certificates from the SystemRoots keychain. To add additional certificates (e.g. the certificates added in the System keychain), place .pem files in /usr/local/etc/openssl/certs and run /usr/local/opt/openssl/bin/c_rehash openssl is keg-only, which means it was not symlinked into /usr/local, because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries. If you need to have openssl first in your PATH run: echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc For compilers to find openssl you may need to set: export LDFLAGS="-L/usr/local/opt/openssl/lib" export CPPFLAGS="-I/usr/local/opt/openssl/include" ==> Summary /usr/local/Cellar/openssl/1.0.2p: 1,793 files, 12.2MB
说明我们成功的将openssl安装到/usr/local/Cellar/openssl/1.0.2p
。
二、更换旧的
不过,我们还有最后一步,那就是当我们使用openssl时,使用的是我们用homebrew新下载的openssl。为了达到这个目的,我们有两种方法。
将homebrew下载的openssl软链接
到/usr/bin/openssl
目录下。这里,我们先将它保存一份老的,然后再软链接新下载的。
$ mv /usr/bin/openssl /usr/bin/openssl_old mv: rename /usr/bin/openssl to /usr/bin/openssl_old: Operation not permitted $ ln -s /usr/local/Cellar/openssl/1.0.2p/bin/openssl /usr/bin/openssl ln: /usr/bin/openssl: Operation not permitted
Operation not permitted提示没有权限操作,对/usr/bin目录下的东西,我已经遇到过几次这个问题了,于是继续google,在stackoverflow上找到了Operation Not Permitted when on root El capitan (rootless disabled)
。
重启系统,当启动的时候我们同时按下cmd+r进入Recovery模式,之后选择实用工具 => 终端,在终端输入如下命令,接口文件系统的锁定,并且重启电脑(cmd+r后,会进入另外一个选择系统启动的界面,在这个界面里面不要马上重新启动,先找到终端,在終端中输入csrutil disable):
$ csrutil disable $ reboot
最后,我们执行前面两个命令,查看版本。
$ sudo mv /usr/bin/openssl /usr/bin/openssl_old $ sudo ln -s /usr/local/Cellar/openssl/1.0.2p/bin/openssl /usr/bin/openssl $ openssl version OpenSSL 1.0.2p 14 Aug 2018 ➜ ~ which openssl /usr/local/opt/openssl/bin/openssl
这样,我们的openssl升级成功了。不过,为了安全起见,我还是重新启动电脑,然后重新开启了csrutil。
csrutil enable reboot

Python是解释型语言,但也包含编译过程。1)Python代码先编译成字节码。2)字节码由Python虚拟机解释执行。3)这种混合机制使Python既灵活又高效,但执行速度不如完全编译型语言。
