CentOS6.5でfabricを動かす

fabric-on-centos.md

結論: pycryptoを2.5に落とせ。

やったこと。

fab deploy とかしたらこんなことを言われた

pycrypto が 文句を言ってるらしい。 http://stackoverflow.com/questions/17319033/fixing-warning-gmp-or-mpir-library-not-found-not-building-crypto-publickkey とか。

mpz-devel, gmp-devel を入れたり pycrypto をビルドしなおしたりとかしたけど、いまいち状況変わらず。

しかたないので pycrypto のバージョンを下げてみる。

sudo easy_install 'pycrypto==2.5'

fabric が動いた。

これは関係ないかもだけど、、、

pycrypto のビルド

gmp5 が /usr/local にインストールされてるからそっちを参照するように setup.py を修正する。

$ pip install --download ./ pycrypto
$ tar zxvf pycrypto-2.6.1.tar.gz 
$ cd pycrypto-2.6.1
$ vi setup.py

有効になった？

お。ありがとうございます。
gmp5 をビルドしないといけないのですねぇ。
