解压redis后，第一次make出现报错：

安装gcc后，继续make出现以下报错：
[root@localhost redis-3.2.5]# make
cd src && make all
make[1]: Entering directory `/data/redis/redis-3.2.5/src'
CC adlist.o
In file included from adlist.c:34:0:

make: *** [all] Error 2redis
解决方法：
第一种：执行 make MALLOC=libc 命令 ，若是执行后报错 或 还有其余错误,建议删除redis全部文件从新解压编译尝试ui
缘由：因为系统没有jemalloc 而只有 libc ，可是默认回去找jemalloc，致使了 make 出错。 因此加参：make MALLOC=libclua
第二种：make CFLAGS="-march=x86-64" spa
在README 有这个一段话。prototype
Allocator
---------
Selecting a non-default memory allocator when building Redis is done by setting
the `MALLOC` environment variable. Redis is compiled and linked against libc
malloc by default, with the exception of jemalloc being the default on Linux
systems. This default was picked because jemalloc has proven to have fewer
fragmentation problems than libc malloc.
To force compiling against libc malloc, use:
% make MALLOC=libc
To compile against jemalloc on Mac OS X systems, use:
% make MALLOC=jemallocserver
在构建Redis时，经过设置来选择非默认的内存分配器htm
MALLOC的环境变量。Redis被编译并连接到libc内存
malloc是默认的，jemalloc是Linux上的默认值。之因此选择这个默认值，是因为事实证实jemalloc的内存更少，碎片化问题比libc malloc严重。string
如今因为没有jemalloc 而只有 libc ，可是默认回去找jemalloc，致使了 make 出错。 因此加这么一个参数。
要强制编译libc malloc，请使用:
% MALLOC = libc
要在Mac OS X系统上编译jemalloc，请使用:
% MALLOC = jemalloc
