redis安装中遇到的问题

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

缘由分析

在README 有这个一段话。linux

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=jemallocredis


说关于分配器allocator, 若是有MALLOC  这个 环境变量, 会有用这个环境变量的 去创建Redis。ui

并且libc 并非默认的 分配器, 默认的是 jemalloc, 由于 jemalloc 被证实 有更少的 fragmentation problems 比libc。spa

可是若是你又没有jemalloc 而只有 libc 固然 make 出错。 因此加这么一个参数。.net

解决办法

1.make MALLOC=libcunix

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

 

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:blog

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

3get
