Deploy XAMPP On ArchLinux

###Installation On ArchLinux, Install xampp via Yaourt:

yaourt xampp

After installation, you will find the default xampp located in “/opt/lampp”. Start/Stop/Restart the xampp via:

/opt/lampp/lampp start/stop/restart

###Adjustment Enable the security via:

/opt/lampp/lampp security

Then you have to use username and password for accessing “http://localhost”, the default username is lampp, password is what you selected.
If you want to add your own Directory, add following lines into “/opt/lampp/etc/httpd.conf:

# Add our own Directory
#<Directory "/yourDirectory/">
<Directory "/home/Trusty/code/octo/heroku/Tomcat/public/">
    Options Indexes FollowSymLinks ExecCGI Includes
    AllowOverride All
    Require all granted
</Directory>

To enable virtualhost, you have to uncomment following line in “/opt/lampp/etc/httpd.conf:

# Virtual hosts
Include etc/extra/httpd-vhosts.conf

Then we should edit the etc/extra/httpd-xampp.conf, to change the security issue:

#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
	Order deny,allow
	Deny from all
	#Allow from ::1 127.0.0.0/8 \
	#	fc00::/7 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 \
	#	fe80::/10 169.254.0.0/16
	Allow from ::1 127.0.0.0/8
	Allow from all
	ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</LocationMatch>

Add more vhosts, the definition is located at /opt/lampp/etc/extra/httpd-vhosts.conf:

<VirtualHost *:80>
DocumentRoot /opt/lampp/htdocs
ServerName localhost
ServerAlias www.localhost
</VirtualHost>


<VirtualHost *:80>
DocumentRoot "/home/Trusty/code/octo/heroku/Tomcat/public/"
ServerName localhost2
ServerAlias www.localhost2
<Directory "/home/Trusty/code/octo/heroku/Tomcat/public/">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>

Add the definition of hostname in /etc/hosts:

127.0.0.1	localhost2.localdomain	localhost2
127.0.0.1 localhosts # for blog using in XAMPP

###Configuration Add the xampp into the startup procedure, in .xinitrc:

sudo /opt/lampp/lampp start &

Then everytime the lampp will automatically start.

Add systemd startup

Configure the systemd startup script via following commands:

$ pwd
/etc/systemd/system

$ cat xampp.service
[Unit]
Description=xampp for ArchLinux, locate in /opt/lampp
After=network.target

[Service]
ExecStart=/opt/lampp/lampp start 
ExecStop=/opt/lampp/lampp stop
Type=forking

[Install]
WantedBy=multi-user.target

Enable auto-start xampp.service by default:

# systemctl start xampp.service
# systemctl enable xampp.service
ln -s '/etc/systemd/system/xampp.service' '/etc/systemd/system/multi-user.target.wants/xampp.service'
# ps -ef | grep http

DXG ScreenSaver Hack

First, download the ScreenSavers hacker form:
http://www.mobileread.com/forums/showthread.php?t=88004
And unzip this file, copy the “Update_ss_0.43.N_dxg_install.bin” to the root directory of Kindle.

Then In kindle, [HOME] -> [MENU] > Settings -> [MENU] > Update Your Kindle. The DXG will automatically reboot.
Now mount the DXG into your computer, touch the “last” file under the linkss folder, as:

	[root@XXXyyy mnt]# cd linkss/
	[root@XXXyyy linkss]# ls
	auto        backups  cover_cache  info.txt          overflow  screensavers
	autoreboot  bin      etc          mounted_824x1200  run
	[root@XXXyyy linkss]# touch last

Now reboot your Kindle Again, your Kindle will remain the last read page as the ScreenSaver.

Explanation:

	--pretty="..." 定义输出的格式
	%h 是提交 hash 的缩写
	%d 是提交的装饰（如分支头或标签）
	%ad 是创作日期
	%s 是注释
	%an 是作者姓名
	--graph 使用 ASCII 图形布局显示提交树
	--date=short 保留日期格式更好且更短

Other tools: gitx (Mac) 和 gitk (任意平台) 在浏览日志历史时十分有用。
###Add Git TAG Add tag for the specified release: “git tag v1-data”, “git tag” to view all of the tags.
Revert the change via;

	git revert HEAD

这将带你到编辑器中。你可以编辑默认的提交信息，或直接 离开它。保存并关闭文件。Or Using the following with no editing:

	$ git revert HEAD --no-edit

Using tag for reverting the changes:

	$ git tag oops
	$ git reset --hard v1
	$ git tag -d oops

More than one modification but commit once:

	$ git add hello.rb
	$ git commit --amend -m "Add an author/email comment"

Change the directory structure:

	git mv hello.rb lib
	git commit -m "Moved hello.rb to lib"

View the directory tree:

	git cat-file -p 4ee1119fb7519dc8298fe5d8e9329f52566afaed

###Merge Merge the branch with master:

	git merge master

when conflicts happens, you will manually merge it.

Revert to specified version:

	git reset --hard <hash>

Clone the remote repository to local, using git clone:

	$ git clone hello cloned_hello
	$ git branch -a
	* master
	  remotes/origin/HEAD -> origin/master
	  remotes/origin/greet
	  remotes/origin/master

git fetch 命令的结果将从远程仓库取得新的提交，但它不会将这些提交合并到本地分支中。If we wnat to sync, then try following:

	[Trusty@~/code/git_learn/git_tutorial/cloned_hello]$ git merge origin/master
	Updating 5de15b7..105a3d0
	Fast-forward
	 README | 1 +
	 1 file changed, 1 insertion(+)
	[Trusty@~/code/git_learn/git_tutorial/cloned_hello]$ cat README 
	This is the Hello World example from the git tutorial.
	(Changed in original)

Clone the directory structure, mainly for backup:

	$ git clone --bare hello hello.git
	Cloning into bare repository hello.git...
	done.
	$ ls hello.git
	HEAD
	config
	description
	hooks
	info
	objects
	packed-refs
	refs

If we want to push changes to the remote, just git push.
迅速跳过克隆仓库，且让我们拉下刚才推送到共享仓库的更改。

	$ cd ../cloned_hello
	$ git remote add shared ../hello.git
	$ git branch --track shared master
	$ git pull shared master
	$ cat README

###On Daemon ####启动 Git 服务器

	# (From the work directory)
	$ git daemon --verbose --export-all --base-path=.

现在，在分开的终端窗口中，转到你的工作目录。

	# (From the work directory)
	$ git clone git://localhost/hello.git network_hello
	$ cd network_hello
	$ ls

你应当看到 hello 项目的拷贝。
####推送到 Git daemon
如果你想要推送到 Git daemon 仓库，添加 –enable=receive-pack 到 git daemon 命令。小心，因为此服务器没有授权，任何人 都能推送到你的仓库。
