我執行了這句：curl -L https://github.com/docker/compose/releases/download/1.9.0/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose，然后報如下錯誤：

[root@stat /]#curl -L https://github.com/docker/compose/releases/download/1.9.0/docker-compose-Linux-x86_64 > /usr/local/bin/docker-compose

curl: (60) Peer's Certificate issuer is not recognized.

More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"

?of Certificate Authority (CA) public keys (CA certs). If the default

?bundle file isn't adequate, you can specify an alternate file

?using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in

?the bundle, the certificate verification probably failed due to a

?problem with the certificate (it might be expired, or the name might

?not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use

?the -k (or --insecure) option.
