自己証明書でSSLしたオレオレgitリポジトリサーバ(以下、オレオレ)と通信する場合のエラー対処

オレオレから、git clone

$ git clone https://example.com/repos.git
Cloning into 'repos'...
fatal: unable to access 'https://example.com/repos.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

自己証明書を持って来て.gitconfigでPATHを指定する

$ vim ~/.gitconfig

[http]
    sslCAInfo = /path/to/shomeisho.crt    ※証明書のPATH

オレオレから、composer install

オレオレにSatisを入れてそこからパッケージを引っ張ってくる場合

$ cat composer.json
{
    "name": "example.com/web",
    "description": "web example.",
    "homepage": "http://example.com",
    "authors": [
        {
            "name": "John Smith",
            "email": "john@example.com"
        }
    ],
    "repositories": [
        {
            "url": "https://example.com/satis/",
            "type": "composer"
        },
        {"packagist": false}
    ],
    "require": {
        "web/package1":"dev-master",
        "web/package2":"dev-master"
    }
}

$ php composer.phar install

オレオレ側ではなく、クライアント側のphp.iniに以下を追記

curl.cainfo=/path/to/shomeisho.crt    ※証明書のPATH
openssl.cafile=/path/to/shomeisho.crt    ※証明書のPATH
