Vyattaにfluentd入れて、fluentd→fluentdでログ集めようとしたけど失敗した

環境 * ESXi5.0 u1 * Vyatta Core 6.4 (VMXNET3、Debianのリポジトリを追加してからVMware公式のVMware Tools入れてる) * fluentd 0.10.22

入れた手順

  1. rvm入れる
# aptitude install ruby-full
# curl -L get.rvm.io | bash -s stable
# source /usr/local/rvm/scripts/rvm
# rvm requirements
# aptitude install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
# rvm install 1.9.3
# rvm use ruby-1.9.3
# rvm use 1.9.3 --default
  1. fluentd入れる
# gem install fluentd

以下のエラーが出た

ERROR:  Loading command: install (LoadError)
    cannot load such file -- zlib
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand
  1. 必要なパッケージ入れる
# rvm pkg install readline

ここで

Error running 'autoreconf -is --force', please read /usr/local/rvm/log/readline/autoreconf.log

が出たら

# rvm --skip-autoreconf pkg install readline

で入れる

# rvm pkg install zlib
# rvm pkg install openssl
  1. ruby1.9.3入れ直す
# rvm remove 1.9.3
# rvm install 1.9.3
# rvm use 1.9.3 --default
  1. fluentd入れる
# gem install fluentd
# fluentd --setup /etc/fluent
# vi /etc/fluent/fluent.conf
# mkdir /var/log/fluent/
# touch /var/log/fluent/vyatta.log
# fluentd -d /var/run/fluentd.pid -c /etc/fluent/fluent.conf

これで、受け側のfluentdにログ飛ばす設定したんだけど、ログは飛ばかなくて以下のエラー

tcpdumpとかいろいろして見てみたんだけど、fluentd同士が生き死にを確認するために飛ばしているというudpのパケットがVMから出ていないようだった

ってこういうの前あったなと思ってググったらKBにありましたよ

UDP packets are dropped from Linux systems using the VMXNET3 Network Adapter

E1000に変えろとかね・・・

もうちょっと検証してみます・・・
