Redis 2.8.18 安裝報錯 error: jemalloc/jemalloc.h: No such file or directory解決方法

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(guān)于分配器allocator， 如果有MALLOC  這個 環(huán)境變量， 會有用這個環(huán)境變量的 去建立Redis。

而且libc 并不是默認(rèn)的 分配器， 默認(rèn)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(dāng)然 make 出錯。 所以加這么一個參數(shù)。

解決辦法

make MALLOC=libc

即

make PREFIX=/opt/redis MALLOC=libc install
