1、下载redis 地址 http://download.redis.io/releases/redis-5.0.2.tar.gz

2、解压tar -zxf redis-5.0.2.tar.gz

3、缺少gcc环境需要yum install gcc -y

3.1 make编译

3.2 报错：

[root@lang redis-5.0.2]# make
cd src && make all
make[1]: Entering directory `/usr/local/redis-4.0.10/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 `/usr/local/redis-4.0.10/src'
make: *** [all] Error 2

redis解压目录下有个README.md文件中有如下一段话：

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

4、编译加上MALLOC=libc 即可

　　 #make MALLOC=libc

5、运行redis

修改配置文件 redis.conf

daemonize no 改为 yes 后台运行：

protected-mode yes 改为no 可以不用输入密码登陆

daemonize yes 改为no

requirepass "xiaoqi@Redis" 这里可以设置自己想要设置的密码/默认是加#的，去掉即可

bind 127.0.0.1  表示只可以本机访问，要是远程访问需要注释掉（前面加#号即可）

6、带配置文件后台启动

[root@lang redis-5.0.2]# src/redis-server redis.conf
