[linux] cron.d 설정으로 haproxy 로그 logrotate 적용

1분 주기로 haproxy 로그 확인해서 100M 넘으면 로테이트해서 500개 까지 보관(crontab 사용하지 않고, /etc/cron.d 설정)

mkdir /etc/logrotate.hourly

cat <<EOF > /etc/logrotate.hourly/haproxy
/var/log/haproxy/haproxy.log
/var/log/haproxy/haproxy-*.log {

  dateformat -%Y%m%d%H-%s

  postrotate
    /usr/bin/pgrep rsyslogd | xargs -I{} kill -s HUP {}
  endscript
}
