Redis安装报错error:jemalloc/jemalloc.h:No such file or directory解决方法

安装Redis

下载Redis：

$ wget https://github.com/antirez/redis/archive/3.2.0.tar.gz

1	$ wget https://github.com/antirez/redis/archive/3.2.0.tar.gz

在安装Redis之前，需要安装Redis的依赖程序tcl，如果不安装tcl在Redis执行make test的时候就会报错的哦。

$ yum install -y tcl

1	$ yum install -y tcl

$ tar xvf 3.2.0.tar.gz -C /usr/local
$ cd /usr/local/
$ mv redis-3.2.0 redis
$ cd redis
$ make
$ make test
$ make install
$ mkdir /etc/redis
$ cp redis/redis.conf /etc/

$ tar xvf 3.2.0.tar.gz -C /usr/local

$ cd /usr/local/

$ mv redis-3.2.0 redis

$ cd redis

$ make

$ make test

$ make install

$ mkdir /etc/redis

$ cp redis/redis.conf /etc/

以redis用户启动redis

$ useradd -s /bin/false -M redis
$ sudo -u redis `which redis-server` /etc/redis.conf

1 2	$ useradd -s /bin/false -M redis $ sudo -u redis `which redis-server` /etc/redis.conf

错误描述

如果在make时，Redis报错：

zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h:55:2: error: #error "Newer version of jemalloc required"

1 2	zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory zmalloc.h:55:2: error: #error "Newer version of jemalloc required"

原因分析

在README有这个一段话。

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

the `MALLOC` environment variable. Redis is compiled and linked against libc

malloc by default, with the exception of jemalloc being the default on Linux

% make MALLOC=jemalloc

Redis在安装时关于内存分配器allocator，如果指定了MALLOC这个环境变量，那么会用这个环境变量的去建立Redis。如果没有，那么就是用默认的分配器

Redis 2.4版本之后，默认使用jemalloc来做内存管理，因为jemalloc被证明解决fragmentation problems（内存碎片化问题）比libc更好。但是如果你又没有jemalloc而只有libc，当make出错时，你可以加这么一个参数即可。

make MALLOC=libc

1	make MALLOC=libc

如果想用jemalloc，安装jemalloc即可。

如果使用yum安装的话需要安装EPEL源。

$ yum install jemalloc
$ rpm -ql jemalloc
/usr/bin/jemalloc.sh
/usr/lib64/libjemalloc.so.1

$ yum install jemalloc

$ rpm -ql jemalloc

/usr/bin/jemalloc.sh

/usr/lib64/libjemalloc.so.1

也可以编译安装，先下载jemalloc：

https://github.com/jemalloc/jemalloc/releases/download/4.2.1/jemalloc-4.2.1.tar.bz2

$ tar xvf jemalloc-4.2.1.tar.bz2
$ cd jemalloc-4.2.1
$ ./configure --prefix=/usr/local/jemalloc
$ make && make install

$ tar xvf jemalloc-4.2.1.tar.bz2

$ cd jemalloc-4.2.1

$ ./configure --prefix=/usr/local/jemalloc

$ make && make install

$ ll /usr/local/jemalloc/
