MacでSSL CA(認証局)証明書インストールする方法が解らない。(2020年に解決)

Last updated at Posted at 2018-04-08

2018年4月頃 作成
2020-08-12 更新

MacOSX 10.8.5
HomeBrewをインストール不可能なMacOSX 10.8.5マシンがある。

OpenSSL 1.0.2o 27 Mar 2018
ruby 2.4.4p296 (2018-03-28 revision 63013) [x86_64-darwin12.6.0]
curl 7.59.0 (x86_64-apple-darwin12.6.0) libcurl/7.59.0 OpenSSL/1.0.2o zlib/1.2.11
Release-Date: 2018-03-14

#1. HomeBrewインストールコマンドを実行しても、エラーになる。

$ /usr/local/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

#2. opensslの証明書を更新。

ruby -ropenssl -e "p OpenSSL::X509::DEFAULT_CERT_FILE"
に出力されるディレクトリを
/usr/local/xxxxxxxxxx/xxxxxx/cert.pem
だとすると、
sudo wget -O /usr/local/xxxxxxxxxx/xxxxxx/cert.pem http://curl.haxx.se/ca/cacert.pem
としても1のエラーは変わらない。

#3. (追記)エラーが変わった。

時間を変えてやってみたところエラーが変わった。
sudo wget -O /usr/local/xxxxxxxxxx/xxxxxx/cert.pem http://curl.haxx.se/ca/cacert.pem
今まではなんだったのか?更新されていなかったのか?

これで更新されたようだ。#4以降は未だに不明。

#4. 【質問】Macで、SSL CA(認証局)証明書インストールする方法が解らない。

SSL CA(認証局)証明書が古くてcurl がエラーになる件
