最近打算用ScyllaDB做分布式数据库，但在CentOS7.6上发现GCC太老需要升级，GCC并不好编译需要很多依赖的和对应的版本，试了两天终于通过了，编译过程比较漫长朋友们需要耐心等待。以下是已经验证过可以正确编译安装的步骤给大家参考，欢迎指教！

CentOS Linux release 7.6.1810 (Core)

Libraries have been installed in:
/usr/local/gcc-9.2.0/lib/../lib64
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
