Redis 安裝報錯

error: jemalloc/jemalloc.h: No such file or directory解決方法

文章轉載http://blog.csdn.net/bugall/article/details/45914867

錯誤描述
安裝Redis 2.8.18時報錯：
zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/data0/src/redis-2.6.2/src'
make: *** [all] Error 2
原因分析
在README 有這個一段話。
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=jemalloc

說關於分配器allocator，如果有MALLOC 這個環境變數，會有用這個環境變數的去建立Redis。
而且libc 並不是默認的分配器，默認的是 jemalloc, 因為 jemalloc 被證明有更少的 fragmentation problems 比libc。
但是如果你又沒有jemalloc 而只有 libc 當然 make 出錯。所以加這麼一個參數。
解決辦法
make MALLOC=libc
