passengerのapacheモジュールインストール時のエラー

エラー詳細

c++: コンパイラ内部エラー: 強制終了 (プログラム cc1plus)
Please submit a full bug report,
Your compiler failed with the exit status 4. This probably means that it ran out of memory. To solve this problem, try increasing your swap space: https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04

メモリが足らないので以下対応する

$ gem install passenger
$ sudo dd if=/dev/zero of=/tmp/swap.img bs=1M count=1024
$ sudo chmod 600 /tmp/swap.img
$ sudo mkswap /tmp/swap.img
$ sudo swapon /tmp/swap.img
$ passenger-install-apache2-module
