## 5.问题

```
#编译emqx报git版本太低
#安装依赖
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker -y
#卸载git
yum -y remove git
rm -rf /usr/bin/git
#下载源码包
wget https://github.com/git/git/archive/refs/tags/v2.33.1.tar.gz
cd git-2.33.1
make prefix=/usr/local/git all
make prefix=/usr/local/git install
vi /etc/profile 
export PATH=$PATH:/usr/local/git/bin
source /etc/profile
git --version
