root,

If you have any questions, issues and/or ideas for improvement please
fork the project and issue a pull request.

If you wish to disable the project .rvmrc file functionality, set
rvm_project_rvmrc=0 in either /etc/rvmrc or ~/.rvmrc.

NOTE: To Multi-User installers, please do NOT forget to add your users to the 'rvm' group.
  The installer no longer auto-adds root or users to the rvm group. Admins must do this.
  Also, please note that group memberships are ONLY evaluated at login time.
  This means that users must log out then back in before group membership takes effect!

Thank you for using RVM!

I sincerely hope that RVM helps to make your life easier and more enjoyable!!!

  ~Wayne


SYSTEM NOTES:

If you do not wish to enable reading of per-project .rvmrc files, simply set:
        export rvm_project_rvmrc=0
within either your /etc/rvmrc or $HOME/.rvmrc file, then log out and back in.


In case your shell exits on entering directory with freshly checked out sources
you should update .rvmrc file, and replace any `exit ` with `return `.


You _must_ read 'rvm requirements' for additional OS specific requirements for
various rubies, and native-extension gems. Expect failures until those are met!


For screen users, please do not forget to read https://rvm.beginrescueend.com/workflow/scre                        en/.
You will need to add 'shell -/bin/bash' to your $HOME/.screenrc to properly load RVM.


Installation of RVM to /usr/local/rvm/ is complete.



Requirements for Linux ( CentOS release 5.7 (Final) )

NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X)
             This is the *original* / standard Ruby Language Interpreter
      'ree'  represents Ruby Enterprise Edition
      'rbx'  represents Rubinius

bash >= 4.1 required
curl is required
git is required (>= 1.7 recommended)
patch is required (for ree and some ruby-head's).

To install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.

NOTE: To all Multi-User installers - DO NOT forget to add your users to the 'rvm' group.
      The installer does not auto-add any users to the rvm group. Admins must do this.
      Group memberships are ONLY evaluated at login time. Log them out, then back in.

Additional Dependencies:
# For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
  ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel ## NOTE:                         For centos >= 5.4 iconv-devel is provided by glibc

  # For JRuby, install the following:
  jruby: yum install -y java

グループと環境変数

・rvmグループに，自分のアカウントを追加する．

$ vigr

・一度logoutして，再度loginすると，環境変数とグループが設定される．

$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/rvm/bin:/home/yc/bin
$ groups
... wheel rvm

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

さくらのVPS 1Gの設定-SSHの設定

SSH公開鍵を用い，ネットワーク経由でログインできるようにします．
※←はオプショナルです．

・さくらの「VPSコントロールパネル」から，指定されたrootパスワードでログインする
・OSのアップグレードをする（yum upgrade）
・自分のユーザアカウントを作成する（useraddコマンド）
・パスワードを設定する（passwdコマンド）
・wheelにsudoでのコマンド実行を許可する（visudoコマンド）
・自分をwheelに追加する（vigrコマンド）
・自分のアカウントに切り替える（su -コマンド）

※sudoをテストする
※SSH公開鍵を生成する（ssh-keygenコマンド）

・自分が持っているSSHの公開鍵をsftpでサーバにアップロードする．
・.ssh/authorized_keysに公開鍵を追加する

$ cat id_rsa.pub >> .ssh/authorized_keys
$ chmod 600 .ssh/authorized_keys

以上です．
