安装需要的库
yum install -y epel-release
yum install jemalloc-devel
yum install gcc
epel的全称叫 Extra Packages for Enterprise Linux 。是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。装上了 EPEL之后，就相当于添加了一个第三方源，版本会比官方的包更新，而且还有一些官方没有的包，比如jemalloc-devel。

# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
