centos中安装、升级git

yum install git如果从老版本升级，则按下面方法。（centos中）先更新系统sudo yum update    安装依赖的包yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker下载git源码并解压缩wget https://github.com/git/git/archive/v2.3.0.zipunzip v2.3.0.zipcd git-2.3.0make prefix=/usr/local/git allmake prefix=/usr/local/git install在这可能会相似下面的错误：/root/git/git-2.3.0/utf8.c:463: undefined reference to `libiconv'而后按后面的方法解决。安装成功后git --version，若不是新版本，则要把编译安装的git路径放到环境变量里查看git所在的路径：whereis gitgit: /usr/bin/git /usr/local/git /usr/share/man/man1/git.1.gz第二个便是git的路径vi /etc/profile    在最后加：export PATH=/usr/local/git/bin:$PATH从新加载source /etc/profilegit --versiongit version 2.3.0大功告成。------------------安装libiconvcd && wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gztar -zxvf libiconv-1.14.tar.gzcd libiconv-1.14./configure --prefix=/usr/local/libiconv  &&  make  && make install建立一个软连接到/usr/libln -s /usr/local/lib/libiconv.so /usr/libln -s /usr/local/lib/libiconv.so.2 /usr/lib而后回到git目录继续编译cd /usr/local/gitmake configure./configure --prefix=/usr/local --with-iconv=/usr/local/libiconvmakemake install
