[【原文链接】QEMIU-基于CentOS系统编译安装部署QEMU环境](http://devops-dev.com/article/651)

* 备份原有的yum源配置
```bash
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
```

* 设置阿里云的yum源
```bash
wget -O /etc/yum.repos.d/CentOS-Base.repo  http://mirrors.aliyun.com/repo/Centos-7.repo
```

* 添加EPEL源
```bash
wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-7.repo
```

* 更新yum缓存
```bash
yum clean all
yum makecache
```

* 安装依赖包
```bash
yum install gcc*
yum install zlib*
yum install -y glib*
yum install install autoconf automakelibtool
yum install SDL-devel
```

* 下载qemuu并解压
```bash
cd /opt
wget https://github.com/qemu/qemu/archive/refs/tags/v2.7.0.tar.gz
tar -zxvf v2.7.0.tar.gz
```

* 编译安装
```bash
cd qemu-2.7.0
./configure
make
make install
```

* 验证qemu
退出后重新登录，然后执行qemu- 加tag，即出现如下命令提示，表示qemu已经编译安装成功
```bash
