安装 redis 数据库

Posted 2020-10-07 薛定谔的猫！

下载redis版本：https://redis.io/download           我下载的是：redis-3.0.6

下载后，在linux上      tar -zxvf redis-3.0.6,进入redis-3.0.6 目录，使用make进行编译

 

在安装Redis，使用make命令编译的时候，抛出异常
[[email protected] redis-3.0.6]# make
cd src && make all
make[1]: Entering directory `/usr/local/development/redis-3.0.6/src‘
    CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory `/usr/local/development/redis-3.0.6/src‘
make: *** [all] Error 2

这个是本地的Linux没有安装gcc的原因，因为我的Linux没有联网所以使用离线安装，也就是先再Windows上下载RPM包，然后移动到Linux上手动安装
安装gcc的步骤：
在ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/6.8/x86_64/os/Packages/连接里 下载gcc所需的RPM包
从网上查，需要下面这些包
cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
cpp-4.4.7-17.el6.x86_64.rpm
gcc-4.4.7-17.el6.x86_64.rpm
gcc-c++-4.4.7-17.el6.x86_64.rpm
glibc-devel-2.12-1.192.el6.x86_64.rpm
glibc-headers-2.12-1.192.el6.x86_64.rpm
kernel-headers-2.6.32-642.el6.x86_64.rpm
libgomp-4.4.7-17.el6.x86_64.rpm
libstdc++-devel-4.4.7-17.el6.x86_64.rpm
mpfr-2.4.1-6.el6.x86_64.rpm
ppl-0.10.2-11.el6.x86_64.rpm

下载完后，新建个目录（在你安装应用的目录下即可，随意），将这些刚下载的包放到目录下，使用
[[email protected] gcc]# rpm -Uvh ppl-0.10.2-11.el6.x86_64.rpm
warning: ppl-0.10.2-11.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY
error: Failed dependencies:
    libgmp.so.3()(64bit) is needed by ppl-0.10.2-11.el6.x86_64

可以看到使用rpm -ivh 有依赖问题，所以我使用的忽略依赖，强制安装
[[email protected] gcc]# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm --nodeps --force
warning: cloog-ppl-0.15.7-1.2.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY

查看gcc是否安装成功
[[email protected] redis-3.0.6]# gcc --version

所有的RPM包安装完后，再使用make命令，抛出下面异常
[[email protected] redis-3.0.6]# make
cd src && make all
make[1]: Entering directory `/usr/local/development/redis-3.0.6/src‘

make[1]: Leaving directory `/usr/local/development/redis-3.0.6/src‘

说是缺少libgmp.so.3 我从http://www.rpmfind.net/linux/rpm2html/search.php?query=gmp&submit=Search+...&system=&arch=连接中下载里了    gmp-4.3.1-12.el6.x86_64.rpm 这个包并安装，再次使用make还是抛出异常
[[email protected] redis-3.0.6]# make
cd src && make all
make[1]: Entering directory `/usr/local/development/redis-3.0.6/src‘
    CC adlist.o
In file included from adlist.c:34:

make[1]: Leaving directory `/usr/local/development/redis-3.0.6/src‘
make: *** [all] Error 2

在Redis的目录中有个redme文件，里面有这么一段
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

Verbose build

这段大概意思是：在Redis时选择一个内存分配器是通过MALLOC变量来设置的，jemalloc是Linux的默认的值。如果你的linux中没有jemalloc 所以抛出这个异常。
使用make MALLOC=libc
安装完成

Hint: It‘s a good idea to run ‘make test‘ ;)
