CentOS6.4のへpython-2.7（ansible用）をインストール
Ansibleのテストをしてみたかったけど
[vagrant@localhost ~]$ python -V Python 2.6.6 [vagrant@localhost ~]$
まじか
pythonはいろいろなツールと関連しているから簡単にバージョンアップできないようなイメージがあるけどどうなんだろう…
epelリポジトリなどを取り込み
sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm sudo yum update -y sudo yum -y groupinstall "Development Tools"
必要なライブラリを取り込む
sudo yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
pythonをインストール
cd /var/tmp git clone https://github.com/tagomoris/xbuild.git sudo xbuild/python-install 2.7.6 /opt/python-2.7 echo 'PATH=/opt/python-2.7/bin:$PATH' >> ~/.bashrc source ~/.bashrc sudo /opt/python-2.7/bin/pip install ansible
※ansibleは入れなくてもいいかもしれないけど他のサーバにも設定しないといけないのか…
確認
[vagrant@localhost tmp]$ source ~/.bashrc [vagrant@localhost tmp]$ python -V Python 2.7.6 [vagrant@localhost tmp]$
クライアント設定
macでいろいろ設定して実行
hostsファイルを作成
