linux 下一键安装lnmp结果Mysql安装失败，解决方法如下：

mv /usr/bin/cmake /usr/bin/cmake.backup

wget http://www.cmake.org/files/v3.0/cmake-3.0.2.tar.gz

tar zxf cmake-3.0.2.tar.gz

cd cmake-3.0.2

./configure

gmake

make && make install

ln -sf /usr/local/bin/cmake /usr/bin/cmake

然后进入到lnmp安装目录后重新运行安装包./install.sh 就可以了
