Graphite on CentOS 8(失敗)

Posted at

Graphiteをインストールする手順メモ

先に言うと、失敗してます。
python3で試してます。python2でやれば動くかも。
公式インストール手順(pip)

# MEMO:: 公式では'python-devel'となっているけど、
#        それだと無いと怒られるのでpython3と指定  
$ sudo yum install python3-devel cairo-devel libffi-devel

python3をデフォルトに指定する

$ sudo alternatives --config python

There are 2 programs which provide 'python'.

  Selection    Command
-----------------------------------------------
*+ 1           /usr/libexec/no-python
   2           /usr/bin/python3

Enter to keep the current selection[+], or type selection number: 2

確認

$ python --version
Python 3.6.8
$ su -
# export PYTHONPATH="/opt/graphite/lib/:/opt/graphite/webapp/"
# pip3 install --no-binary=:all: https://github.com/graphite-project/whisper/tarball/master
# pip3 install --no-binary=:all: https://github.com/graphite-project/carbon/tarball/master
# pip3 install --no-binary=:all: https://github.com/graphite-project/graphite-web/tarball/master

DBセットアップ

ここでコケる。

# PYTHONPATH=$GRAPHITE_ROOT/webapp django-admin.py migrate --settings=graphite.settings --run-syncdb

たしかに graphite がないので、pipでインストールしようと試みる

# pip3 install graphite
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

この print の書き方はpython2なのでそりゃしくじると。
graphiteを入れるにはpip2である必要がありそう。

公式曰く、graphiteはpython2で書かれてるらしい。。
