服务器CentOS6.5,安装git并使用
1.卸载CentOS6.5自带的git版本，以便安装更高版本的git
查看版本号
# git --version
git version 2.1.2
卸载：# yum remove git
2.下载git2.1.2版本并解压：
# wget https://www.kernel.org/pub/software/scm/git/git-2.1.2.tar.gz
# tar xzf git-2.1.2.tar.gz
若下载时报--no-check-certificate 则在wget 后添加： --no-check-certificate
或者：echo "check_certificate = off" >> ~/.wgetrc
3.安装git并添加到环境变量中
# cd git-2.1.2
# make prefix=/usr/local/git all
# make prefix=/usr/local/git install
# echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
# source /etc/bashrc
错误：没有安装libssl
错误：安装libssl-dev时No package libssl-dev available
解决办法：yum install expat-devel
注：libssl-dev是ubuntu系统的库，而centos系统对应的是openssl-devel ，所以运行centos中运行yum install openssl-devel，ubuntu系统运行apt-get install libssl-dev
错误：make[1]: *** [perl.mak] Error 2
解决办法：yum install perl-ExtUtils-MakeMaker package
