想來想去仍是想試試把個人博客轉成Jekyll, 一方面爲了git管理, 另外一方面實在是感受請求過多速度太慢, 可改造性太差. 通過遷移後, 默認主題, 速度槓槓的, 顯示時間不到 500ms哦~

安裝Jekyll

本文在CentOS7環境下操做.

環境須要

Ruby
RubyGems
NodeJS
Python 2.7(Whidy比較懶, 貌似CentOS7自帶? 仍是啥時候裝了, 不會的本身搜一下= =.)

安裝Ruby2.5.0和RubyGems

目前最新穩定版本是 2.5.0, CentOS自帶源的版本比較老, 咱們須要第三方源 rbenv來安裝最新穩定版, 安裝方法以下:

安裝rbenv和Ruby依賴的組件php

# yum install -y git-core zlib zlib-devel gcc-c++ patch readline readline-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison curl sqlite-devel

安裝rbenv和rub-build(務必在非root用戶的home下面操做)html

# cd ~
# git clone git://github.com/sstephenson/rbenv.git .rbenv
# echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
# echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
# git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
# echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
# source ~/.bash_profile

查看當前可安裝的Ruby版本node
```
# rbenv install -l
```
安裝目前最新穩定版本2.5.0python
```
# rbenv install -v 2.5.0
# rbenv rehash
```
rbenv rehash的做用是有多個Ruby版本的時候要執行的mysql
檢查安裝是否成功nginx
```
# rbenv versions
```
設置爲全局(不然ruby命令沒法使用?)並檢測版本是否正確c++
```
# rbenv global 2.5.0
# ruby -v
```
可選/必選安裝bundle, 由於參考的安裝資料包含Rails, 因此這個是否必須安裝尚不肯定, 若是同時須要Rails, 能夠查看底部的參閱文檔.git
```
# gem install bundler
```

實際上整個安裝過程已經把 RubyGems安裝好了?

參閱:github

Install Ruby on Rails with Rbenv on CentOS 7

其它:sql

安裝Ruby-官方文檔

安裝`NodeJS`

這個比較簡單, 直接安裝就行了

# yum install nodejs

用 RubyGems 安裝 Jekyll

$ gem install jekyll

建立一個Jekyll站點

接下來在當前用戶的目錄下建立一個博客站點並開啓服務

# cd ~
# jekyll new blog
# cd blog
# jekyll serve --host 0.0.0.0

此時打開瀏覽器訪問[server ip]:4000便可.(例如http://118.0.156.000:4000/)

Wordpress站點遷移至Jekyll全過程

官方有遷移文檔, 支持不少種類型的博客遷移, 因此看起來也就比較簡單了, 官方文檔 Import your old & busted site or blog for use with Jekyll., 咱們來嘗試Wordpress遷移.

先按照他的示例, 按照本身的網站進行修改, 大體以下

$ ruby -rubygems -e 'require "jekyll-import";
    JekyllImport::Importers::WordPress.run({
      "dbname"   => "yourWordpressDatabaseName",
      "user"     => "root",
      "password" => "IcannotTellYou",
      "host"     => "localhost",
      "port"     => "3306",
      "socket"   => "",
      "table_prefix"   => "wp_",
      "site_prefix"    => "",
      "clean_entities" => true,
      "comments"       => true,
      "categories"     => true,
      "tags"           => true,
      "more_excerpt"   => true,
      "more_anchor"    => true,
      "extension"      => "html",
      "status"         => ["publish"]
    })'

保證配置無誤後, 回車, 執行報錯!

Traceback (most recent call last):
        1: from /home/whidy/.rbenv/versions/2.5.0/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'
/home/whidy/.rbenv/versions/2.5.0/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- ubygems (LoadError)

蛋疼, 查了下資料說多是rubygems的bug, 參閱[Ruby [SOLVED]: After ruby update to 2.5.0, require 'bundler/setup' raise exception](http://www.cloudypoint.com/Tu... 而後看了下, 貌似真的是的, 立馬升級

$ gem update --system

我說gem安裝很是坑爹, 毫無提示, 都不知道是否是正在處理執行的命令, 其實已經在執行了, 根據網絡狀況多等待一下. 接着唰唰唰的出來一大段, 一直到出現RubyGems system software updated, 就更新完了, 咱們再嘗試遷移命令... 又報錯!!!

Traceback (most recent call last):
        2: from -e:1:in `<main>'
        1: from /home/whidy/.rbenv/versions/2.5.0/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'
/home/whidy/.rbenv/versions/2.5.0/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require': cannot load such file -- jekyll-import (LoadError)

蛋疼, 上次不是裝了嗎, 仍是我記錯了. 好吧再裝一遍

$ gem install jekyll-import

而後再執行, 反覆報錯... 因而反覆執行各類依賴包... 總結以下

$ gem install sequel
$ gem install unidecode
$ gem install mysql2

這裏說要mysql2, 而後執行上面的命令報錯, 又說要mysql-devel, 服了- -, 那隻能一步步試試看了.

$ yum install mysql-devel

接着試

$ gem install mysql2

再跑遷移命令, 繼續報錯... 信息以下

1: from /home/whidy/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gem
/home/whidy/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/mysql2-0.5.0/li
111) (Sequel::DatabaseConnectionError)

查到說是要填寫剛纔遷移命令裏面的socket, 這個填啥呢, 我查了半天有各類各樣的, 好比/var/run/mysqld/mysqld.sock, /tmp/mysql.sock等等, 多是他們都是mysql, 而我是MariaDB, 爲了從根本問題上下手, 仍是看看個人MariaDB的配置文件裏面怎麼寫的吧.

這裏須要說明的是, 個人Wordpress數據庫和要遷移到的Jekyll都在同一服務器上, 所以 host這裏填寫的是 localhost

$ sudo vi /etc/my.cnf

查到socket=/var/lib/mysql/mysql.sock, 那麼修改遷移配置以下:

$ ruby -rubygems -e 'require "jekyll-import";
    JekyllImport::Importers::WordPress.run({
      "dbname"   => "yourWordpressDatabaseName",
      "user"     => "root",
      "password" => "IcannotTellYou",
      "host"     => "localhost",
      "port"     => "3306",
      "socket"   => "/var/lib/mysql/mysql.sock",
      "table_prefix"   => "wp_",
      "site_prefix"    => "",
      "clean_entities" => true,
      "comments"       => true,
      "categories"     => true,
      "tags"           => true,
      "more_excerpt"   => true,
      "more_anchor"    => true,
      "extension"      => "html",
      "status"         => ["publish"]
    })'

慢慢的, 從前面十幾條錯誤, 減小到了最後一條

Could not require 'htmlentities', so the :clean_entities option is now disabled.

看來仍是比較成功的... 那就裝一個試試看吧

$ gem install htmlentities

安裝後, 再次執行遷移命令, 搞得心都要碎了... 複製粘貼回車...

額, 沒. 有. 任. 何. 反. 應. 的. 結. 束. 了... 難道成功了?

在安裝Jekyll的目錄下編譯一下看看...

[whidy@VM_0_3_centos blog]$ jekyll b

又報錯...

查了下大概是說Liquid的正則規則, 面對{{這種玩意就掛了. 把它改爲{ {, 參閱: Liquid Exception: Variable '{{ {0}' was not properly terminated with regexp: /}}/ in #466, 而後我就去_posts目錄把這篇文章手動改了... 再jekyll b一下.

這樣就算完成了? 刷新一下我才配置的Nginx二級域名頁面, 方法大體如原文, 我靠, 昨天不是搞好了403錯誤嗎? 咋又來, 不過不怕, 已經知道是權限問題了, 咱們在分析下哪裏出問題. (而後一陣胡亂修改權限後就行了- -,), 我認爲估計有效的命令是這一條
