安装oneinstack时，在进行到Nginx安装的过程中出现错误
make[2]: Leaving directory `/oneinstack/oneinstack/src/openssl-1.1.1g’
make[1]: Leaving directory `/oneinstack/oneinstack/src/nginx-1.18.0′
make: *** [build] Error 2
Nginx install failed, Please Contact the author!
这是因为系统缺少必要的工具和依赖包，工具有gcc，gcc-c++。依赖包有 pcre-devel ，zlib-devel，openssl-devel 这些通过yum安装即可。安装完成后重新进行oneinstack的安装配置，就没有问题了。
yum -y install gcc gcc-c++ make automake autoconf kernel-devel ncurses-devel libxml2-devel openssl-devel curl-devel libjpeg-devel libpng-devel pcre-devel libtool-libs freetype-devel gd zlib-devel file bison patch mlocate flex diffutils readline-devel glibc-devel glib2-devel bzip2-devel gettext-devel libcap-devel libmcrypt-devel cmake
