My Octopress Blog

Rise of the Apes.

再搭Octpress

本文主要参照Octopress Setup来搭建博客，数月前我曾写了Octopress的落成，当时刚上手，迷迷糊糊就搭建好了博客，就两个时间点的比较而言，自认为对git以及ssh都相对熟练了许多，因此对搭建博客的整个流程都不再是迷迷糊糊过来的，所以最好你是熟悉ssh和git的，git的教程可以访问git-scm.com/book/zh，需要梯子。

下面开始搭建了……

git

首先安装git

sudo apt-get install git

Ruby 1.9.3 by RVM

然后安装Ruby1.9.3，教程说有两种方法——rbenv or RVM，我选择了后者。

RVM

先装RVM，参考Installing Ruby With RVM

sudo apt-get install curl

下面的命令不要执行了…翻到下面RVM again

curl -L https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable --ruby

执行完毕后输出的信息包含一下内容：
# [username],
#
# Thank you for using RVM!
# I sincerely hope that RVM helps to make your life easier and
# more enjoyable!!!
#
# ~Wayne

try Ruby 1.9.3

sudo apt-get install ruby-rvm
rvm install 1.9.3

在执行完上个命令的时候我没看仔细就开始了这个步骤，然后就有了如下的错误信息，其实上个步骤也有错误信息，选择性忽视掉了红字。

ERROR: The requested url does not exist: 'ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-.tar.bz2'
ERROR: Error running 'bunzip2 < '/usr/share/ruby-rvm/archives/ruby-1.9.3-.tar.bz2' | tar xf - -C /usr/share/ruby-rvm/tmp/rvm_src_8445', please read /usr/share/ruby-rvm/log/ruby-1.9.3/extract.log
ERROR: There has been an error while trying to extract the source.  
Halting the installation.
ERROR: There has been an error fetching the ruby interpreter. Halting the installation.

回去看才发现有两段错误信息

part 1:

* WARNING: You're using ~/.profile, make sure you load it,
add the following line to ~/.bash_profile if it exists
otherwise add it to ~/.bash_login:

  source ~/.profile

part 2:

Missing required packages: git-core.
RVM autolibs is now configured with mode '2' => 'check and stop if missing',
please run `rvm autolibs enable` to let RVM do its job or run and read `rvm autolibs [help]`
or visit https://rvm.io/rvm/autolibs for more information.

back to RVM

回去重装RVM，执行

curl -L https://get.rvm.io | bash -s stable --ruby

这次提示有些不同，他检测到RVM有错误：

It looks you are one of the happy Ubuntu users,
RVM packaged by Ubuntu is old and broken,
follow this link for details how to fix:
  http://stackoverflow.com/a/9056395/497756

不过他提供了一个网址，来自著名的stackoverflow，以下内容选自stackoverflow：

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output): (这里说要启动新的终端，应该不会输出什么)

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.(如果有输出要尝试启动新终端，不然就重启电脑。PS：我没启动新终端没输出，一开理解错误，我启动新终端，有输出，然后我以为正常了，然后开始了下面的操作。。。晕)

RVM again

install RVM：//期间输入三次左右的密码，下面的命令斜杠不是我加进去的，最好不要漏了

\curl -L https://get.rvm.io | bash -s stable --ruby --autolibs=enable --auto-dotfiles

好像下面是输出：

  If you find you need some hand-holding, take a look at [Installing Ruby on Ubuntu 12.04](http://blog.coolaj86.com/articles/installing-ruby-on-ubuntu-12-04.html), which gives a bit more explanation.
 * To start using RVM you need to run `source /home/liaobz/.rvm/scripts/rvm`
   in all your open shell windows, in rare cases you need to reopen all shell windows.

Ruby 1.9.3

运行

rvm install 1.9.3

输一次密码之后再下载，我擦嘞，9789K的东西提示我要40多分钟，我想先去看一集《权利的游戏》了……操蛋的ubuntu12.04自带的电影播放机，ass和srt都加载不了，好在有深度影音……那可是人家葬礼啊，让个小子在那里卖萌(那小子是死者儿子…)……兰尼斯特家的侏儒也来卖萌……终于装完了……深度影音暂停后最小话会自动播放，播放放最小话才是暂停……

言归正传，先改个东西，选择终端->菜单->编辑(Edit)->配置文件首选项(Profile Preferences)->标题和命令(Title and Command)->命令(Command)->勾上以登录Shell方式运行命令(Run command as a login shell)

快捷一点就是先选中终端窗口，Alt+E,O,然后剩下的看上面

接着执行(貌似还得重启终端)

rvm use 1.9.3

如果你偷懒没做上面的改动，会有下面的提示

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

意思就是你还是要改

rvm rubygems latest

然后

usrname@pcname:~$ ruby --version
ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]

Ruby就算好了，可以← Return to setup了。

Setup Octopress

git clone git://github.com/imathis/octopress.git octopress
cd octopress    # If you use RVM, You'll be asked if you trust the .rvmrc file (say yes).

提示了一大段，选yes，接着下两个命令都不会出上面大问题

gem install bundler
bundle install

如果你一边在看官网教程，你会发现上面有个rbenv rehash，那句不要执行，因为我用的RVM方式(# If you use rbenv, rehash to be able to run the bundle command)，我貌似断了下网，Ctrl+C了一下，重新执行，输出以下内容：

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

rake install

Octopress Setup Done!
Next Steps Set up deployment
这次我选择Deploying to Github Pages »，上次的Heroku太慢了

Deploying to Github Pages

在登陆github前提下访问new Github repository，新建一个与用户名同名的repository，记住网页上提供的SSH地址，终端运行

rake setup_github_pages

输入刚才的SSH地址，输出提示若干，接着终端运行

rake generate
rake deploy

此时应该是算完成了的，我自己倒是粗心做了比较多多余的事。官方说改动在十分钟左右生效，我的在提交过了十分钟还是不能访问，估计这个过程会稍微久一点。

PS:昨天后面太晚没去管了，回来发现liaobz.github.io还是上不去，反倒是liaobz.github.io/liaobz可以上去了。我发誓我是参照With Github User/Organization pages来的，而不是参照的With Github Project pages (gh-pages)，总之我不考究了。

最终还是发现了我失误在什么地方，毕竟gh-pages不能独立域名不幸福啊……我新建的Repository Name是liaobz，这是错误的，正确的应该是liaobz.github.com，嗯 就这么多。

本文特地尽可能多的将错误步骤贴上博客，希望被官方教程误导了的同学可以检索到，从而解决乃至避免错误，本文难免有疏漏/错误的地方，欢迎不吝指出。

下面是一点点补充，如果你的执行步骤中出现了以下语句

Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

你最好先按顺序执行这三条命令，设定用户名/密码，然后是修改提交信息吧好像

git config --global user.name "Your Name"
git config --global user.email you@example.com
git commit --amend --reset-author

执行rake deploy后输出的语句包含下面内容

## Pushing generated _deploy website
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

应该是忘了配SSH Keys了，自行补上即可。
