tmuxセッション内でsshした先でtmuxのコマンドをssh元に送信する †

• 下記のようなことがやりたい
  1. [LOCAL]:$ tmux
  2. [LOCAL]:$ ssh REMOTE
  3. [REMOTE]:$ tmux select-pane -D

• tmuxのソケットをsshでフォワードすることで可能

  ssh -R /tmp/tmux-<REMOTE_UID>/default:/tmp/tmux-<LOCAL_UID>/default REMOTE_SERVER

  • リモートサーバ上の、/tmp/tmux-<REMOTE_UID>/default がすでに存在していると、ソケット作成に失敗するので、あらかじめ削除しておく必要がある

コマンドオプション †

• -r
  • プリフィックスを1回だけ入力して、以降、同じショートカットキーを連続で入力できる。

    bind -r n next-window

  • 連続入力の制限時間は、repeat-timeで設定できる。デフォルトは500ms。

    set-option -g repeat-time 1000

TPM (Tmux Plugin Manager) †

• github
  • https://github.com/tmux-plugins/tpm
• インストール

  git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

• tmux.conf設定

  # List of plugins
  set -g @plugin 'tmux-plugins/tpm'
  set -g @plugin 'tmux-plugins/tmux-sensible'
  
  # Other examples:
  # set -g @plugin 'github_username/plugin_name'
  # set -g @plugin 'git@github.com/user/plugin'
  # set -g @plugin 'git@bitbucket.com/user/plugin'
  
  # Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
  run '~/.tmux/plugins/tpm/tpm'

• リロード

  $ tmux source ~/.tmux.conf

RHEL6.3でtmuxのビルド †

• tmuxのソース
  • https://github.com/tmux/tmux
• 依存PKG1 : libevent 2.x
  • RHEL6の標準は1.4なので、下記からソースを取ってきてビルドする
  • http://libevent.org/
  • ビルド後やること
    • libeven-2.x.so.xのlibディレクトリをLD_LIBRARY_PATHに通すなどして、参照できるようにする（もしくは参照できる場所にmake installする。libevent1.4との衝突に注意)
    • /usr/lib64/pkgconfig配下に、<make install先DIR>/lib/pkgconfig/libevent.pcを配備(リンクでもOK）
• 依存PKG2 : ncurses
  • 標準DVDからインストール可能
  • ncurses-develも必要
