运行 install_server.sh 的时候会提示你配置redis端口号、配置文件路径等输入项。这里假设端口号为6666，配置文件为/etc/redis/6666.conf。
最终在生成启动文件/etc/init.d/redis_6666。

通过/etc/init.d/redis_6666 start可以读取配置文件启动redis，直接运行redis-server也是可以启动的，只不过这个时候是使用默认配置，而不是读取配置文件。
如果你直接运行redis-server的话，就有可能爆出一堆警告。

22325:M 20 Feb 17:08:02.792 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.

按照他的提示一点点修改一下。最后将其添加到开机启动项，在/etc/rc.local添加如下配置：

echo never > /sys/kernel/mm/transparent_hugepage/enabled
/etc/init.d/redis_6879 start
