redis安装中遇到的问题

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

1.错误描述：

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

说关于分配器allocator，如果有MALLOC 这个环境变量，会有用这个环境变量的去建立Redis。

而且libc 并不是默认的分配器，默认的是 jemalloc, 因为 jemalloc 被证明有更少的 fragmentation problems 比libc。

但是如果你又没有jemalloc 而只有 libc 当然 make 出错。所以加这么一个参数。

解决办法

1.make MALLOC=libc

2.更新jemalloc，参考http://blog.csdn.net/xiaofei_hah0000/article/details/52214592

2.错误描述：

You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] Error 1

解决办法：

wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz  
sudo tar xzvf tcl8.6.1-src.tar.gz  -C /usr/local/  
cd  /usr/local/tcl8.6.1/unix/  
sudo ./configure  
sudo make  
sudo make install
