Linux安装redis全步骤

第一步：下载安装包

  访问https://redis.io/download  到官网进行下载。

第二步：安装

  1.通过远程管理工具，将压缩包拷贝到Linux服务器中，执行解压操作

2.进入解压文件目录使用make对解压的Redis文件进行编译

   图示：这里因为我redis的安装目录在 /usr/src

安装报错！！！gcc命令报错！！

需要安装GCC编译工具！！！
编译源码：make

（1）若出现如下提示，则说明未安装gcc，使用命令安装gcc：yum install gcc

[root@localhost redis-2.8.17]# make
cd src && make all
make[1]: Entering directory `/root/redis-2.8.17/src‘
    CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory `/root/redis-2.8.17/src‘
make: *** [all] Error 2

（2）若出现如下提示，则将make改为make MALLOC=libc，推测是因为编译库的问题。

[root@localhost redis-2.8.17]# make
cd src && make all
make[1]: Entering directory `/root/redis-2.8.17/src‘
    CC adlist.o
In file included from adlist.c:34:
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 `/root/redis-2.8.17/src‘
make: *** [all] Error 2

3.编译成功后，进入src文件夹，执行make install进行Redis安装。

   如下图示安装完成，界面如下：

直接启动

直接运行redis-server即可以启动redis

redis服务器默认会使用6379端口，通过–port参数可以自定义端口号：

redis-server --port 6380

[root@linux1 redis-5.0.7]# ./redis-server
-bash: ./redis-server: No such file or directory
