install git server

all the precedure is written in this article.

 但是我却碰到了一个很奇怪的问题，就是无论如何也clone不了新建的项目：
 fatal: protocol error: bad line length character: fatal: The remote end hung up unexpectedly 
有人说可以看一下这个命令的输出：
ssh mathieu@192.168.1.52 git-receive-pack /var/www/gitproject.git
然后我就看了：

This is BASH 4.2 - DISPLAY on :0.0

看起来最后一行好像是git的输出，而且没有错。那前面三行是什么东西？这段话好像每次ssh都会给我，于是去看了一眼.barshrc

# Looks best on a black background.....
#echo -e "${CYAN}This is BASH ${RED}${BASH_VERSION%.*}${CYAN} - DISPLAY on ${RED}$DISPLAY${NC}\n"
#date
#if [ -x /usr/games/fortune ]; then
#    /usr/games/fortune -s     # makes our day a bit more fun.... :-)
#fi

#function _exit()       # function to run upon exit of shell
#{
#    echo -e "${RED}Hasta la vista, baby${NC}"
#}
#trap _exit EXIT

把这些注释掉就好了，如此人说说：
The complaint is actually that the remote didn't reply with a proper git response - ie, there's a problem on the server running . (The first four bytes should be the line length - instead, they were the characters Unab... probably an error message of some kind.)
真的是手贱为啥要弄个无聊的欢迎信息在bashrc里呢。
