CentOs7 ：
git clone https://github.com/frrouting/frr.git frr
在执行make check的时候会有报错，认为可能有人提交了新的修改导致当前版本不可用，又重新指定release版本的方式下载安装代码。
git clone -b stable/6.0 https://github.com/frrouting/frr.git frr
安装json
yum install json-c json-c-devel
安装python
yum install epel-release
yum install python34
注意：上面的安装方法并未安装pip和setuptools，如果你要安装这两个库可以使用下面的命令：
curl -O https://bootstrap.pypa.io/get-pip.py
/usr/bin/python3.4 get-pip.py
ln -sf /usr/bin/python3.4 /usr/bin/python
2、 一键安装解决依赖
yum install git autoconf automake libtool make \ readline-devel texinfo net-snmp-devel groff pkgconfig \ json-c-devel pam-devel bison flex pytest c-ares-devel \ python-devel systemd-devel python-sphinx libcap-devel
yum -y install cmake
安装yang
cd libyang
mkdir build; cd build
cmake -DENABLE_LYD_PRIV=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr \
-D CMAKE_BUILD_TYPE:String="Release" ..
make
sudo make install
