Redhat 4说实话真心是太老了，可是没办法，给的环境就是这个，所以接受折磨吧，

这里把整个过程记录下来，留待后用。

1 安装yum

机器上没有一个软件包管理器着实蛋疼，所以首先是将这个搞定，下面是步骤

wget http://yum.baseurl.org/download/2.0/yum-2.0.8-1.src.rpm
rpmbuild --rebuild yum-2.0.8-1.src.rpm
cd /usr/src/redhat/RPMS/noarch/
rpm -ivh yum-2.0.8-1.noarch.rpm

vi /etc/yum.conf

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
[base]
name=Red Hat Linux $releasever - $basearch - Base
baseurl=http://vault.centos.org/4.6/os/i386/


[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://vault.centos.org/4.6/updates/i386/

vi /etc/yum.repos.d/CentOS-Base.repo

#CentOS-Base.repo
#
# CentOS-4 is past End of Life ... use at your own risk

[base]
name=CentOS-$releasever - Base

gpgcheck=1
gpgkey=http://vault.centos.org/RPM-GPG-KEY-centos4

#released updates 
[update]
name=CentOS-$releasever - Updates 
baseurl=http://vault.centos.org/4.9/updates/$basearch/
gpgcheck=1
gpgkey=http://vault.centos.org/RPM-GPG-KEY-centos4

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=http://vault.centos.org/4.9/addons/$basearch/
gpgcheck=1

#additional packages that may be useful

gpgkey=http://vault.centos.org/RPM-GPG-KEY-centos5

#additional packages that extend functionality of existing packages
[centosplus]

baseurl=http://vault.centos.org/4.9/centosplus/$basearch/
gpgcheck=1

gpgkey=http://vault.centos.org/RPM-GPG-KEY-centos4

#contrib - packages by Centos Users

gpgcheck=1

gpgkey=http://vault.centos.org/RPM-GPG-KEY-centos4

选用中科大的源：centos.ustc.edu.cn

最后一步，update

yum update

2 搭建git服务器

首先是安装git所需的一些依赖包

yum install curl
yum install curl-devel
yum install zlib-devel
yum install openssl-devel
yum install perl
yum install expat-devel
yum install gettext-devely

wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.gz

tar zvxf git-latest.tar.gz 
cd git-2013-03-29/（这个版本可能和我不一样，看下载的时间）
autoconf
./configure 
make
make install
git -version

git version 1.8.2.GIT

这时还需要做一件事，就是配置环境变量

在.bashrc和.bash_profile中添加一句

export PATH=/home/svn/git-2013-03-29:$PATH（其中路径为下载的git源码路径，因为安装到了那个目录下）

这个我就不罗嗦了，直接上步骤吧，跟着来就可以了

[root@localhost git]# mkdir test
[root@localhost git]# git init --bare test
Initialized empty Git repository in /home/git/test/
[root@localhost git]# cd test/
[root@localhost test]# mkdir initial
[root@localhost test]# cd initial/
[root@localhost initial]# git init
Initialized empty Git repository in /home/git/test/initial/.git/
[root@localhost initial]# git remote add origin /home/git/test
[root@localhost initial]# touch Readme
[root@localhost initial]# git add Readme 
[root@localhost initial]# git commit -m "initial commit"
[master (root-commit) f067423] initial commit
 Committer: root <root@localhost.localdomain>
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

 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 Readme

有时候，我们需要单独安装nginx，来处理大量的下载请求。单独在Centos5安装nginx遇到的rewrite和HTTP cache错误解决办法：

wget http://nginx.org/download/nginx-0.8.33.tar.gz
tar -zxvf nginx-0.8.33.tar.gz 
cd nginx-0.8.33
./configure --prefix=/usr/local/nginx

安装Nginx时报错

./configure: error: the HTTP rewrite module requires the PCRE library.

安装pcre-devel解决问题
yum -y install pcre-devel

错误提示：./configure: error: the HTTP cache module requires md5 functions
from OpenSSL library.   You can either disable the module by using
--without-http-cache option, or install the OpenSSL library into the system,
or build the OpenSSL library statically from the source with nginx by using
--with-http_ssl_module --with-openssl=<path> options.

解决办法：

yum -y install openssl openssl-devel

总结：

yum -y install pcre-devel openssl openssl-devel

./configure --prefix=/usr/local/nginx

make

make install

一切搞定
