fluentd

Fluentdインストール（１台のみでApacheのログでテスト）†

# yum install sudo -y
# curl -L https://toolbelt.treasuredata.com/sh/install-redhat-td-agent2.sh | sh
→公式インストール手順。リポジトリを引っ張ってインストール。
# cd /etc/td-agent
# cp -p td-agent.conf td-agent.conf.org
# vim td-agent.conf

Apacheの場合ここから†

<source>
type tail
path /var/log/httpd/*access_log
pos_file /tmp/access_log.pos
format apache2
tag apache2.access_log
</source>

<match apache2.access_log>
 type file
 path /var/log/td-agent/copy-access_log
</match>

nginxの場合ここから†

<source>
type tail
path /var/log/nginx/access.log
pos_file /var/lib/fluent/access.pos
tag nginx.access
format /^(?<remote>[^ ]*) (?<host>[^ ]*) (?<user>[^ ]*) \[(?<time>[^\]]*)\] "(?<method>\S+)(?: +(?<path>[^\"]*) +\S*)?" (?<code>[^ ]*) (?<size>[^ ]*)(?: "(?<referer>[^\"]*)" "(?<agent>[^\"]*)" "(?<forwader>[^\"]*)")?$/
time_format %d/%b/%Y:%H:%M:%S %z
</source>

# chmod 775 /var/log/nginx
# usermod -G nginx td-agent
