CentOS7.8下升级Git1.8.3.1升级到Git2.2.

git上传代码提示报错，如图:

卸载老版本git：

yum remove git

安装当前环境配置：

yum install-y gcc curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc xmlto perl-devel perl-CPAN autoconf*

下载git2.2.1并将git添加到环境变量中，按顺序执行，有些步骤可能需要一会，静静等待：

# wget https://github.com/git/git/archive/v2.2.1.tar.gz

# tar zxvf v2.2.1.tar.gz

# cd git-2.2.1

# make configure

# ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv

# make all doc

# make install install-doc install-html

# echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc

# source /etc/bashrc
