Updating apache configuration

Due to ArchLinux’s “pacman -Syu –noconfirm”, My apache upgraded from 2.2 to 2.4, thus the configuration file won’t work for the new version. When using “systemctl restart httpd.service”, it complains some module won’t be loaded.

For solving this problem, first make sure you upgraded to the newest version, then go to directory of “/etc/httpd/conf”, backup your own httpd.conf, then move the httpd.conf.pacnew into httpd.conf, then restart the httpd.service.

The configuration of the httpd.conf should also be upgraded, notice the following lines in my own configuration file:

	DocumentRoot "/home/Trusty/code/octo/heroku/Tomcat/public"
	#DocumentRoot "/srv/http"
	#<Directory "/srv/http">
	<Directory "/home/Trusty/code/octo/heroku/Tomcat/public">

Restart again, and now your apache should work properly again.

Converting Markdown into PDF under ArchLinux

Today I want to convert the webpages which wrote from markdown into PDF format file. Following is the steps for how to convert. Just one command is OK:

	pandoc jailbreak.md -o jailbreak.pdf --latex-engine=xelatex -V mainfont="WenQuanYi Zen Hei"

But the link will cause the format ugly, then we have to use a template for fixing this, download the template from following URL: https://raw.github.com/tzengyuxio/pages/gh-pages/pandoc/pm-template.latex Then put it into the same directory, replace the following lines with the fonts which you have installed on your system:

	# Following will be deleted
	\setCJKmainfont{LiHei Pro} 	% 設定中文字型
	\setCJKmainfont{WenQuanYi Zen Hei} 	% 設定中文字型

Now you lock of Microsoft fonts, simply copy it from your own windows machine, and setup a link

	ln -s /windows/Windows/Fonts /usr/share/fonts/WindowsFonts
	# Update font cache
	fc-cache

Generate the pdf file with the following command:

	pandoc jailbreak.md -o jailbreak1.pdf --latex-engine=xelatex -V mainfont="WenQuanYi Zen Hei" --template=pm-template.latex

Now you will see the well-formated PDF file has been generated from the Markdown file.
