1. 安装步骤
下载，解压，make
1.1 下载解压：
wget http://download.redis.io/releases/redis-4.0.9.tar.gz
tar xzf redis-4.0.9.tar.gz
1.2 编译安装：
1 make：
cd redis-4.0.9/
make
或者（详见问题2说明）
make MALLOC=libc
执行结果：
LINK redis-server
INSTALL redis-sentinel
CC redis-cli.o
LINK redis-cli
CC redis-benchmark.o
LINK redis-benchmark
INSTALL redis-check-rdb
INSTALL redis-check-aof
Hint: It's a good idea to run 'make test' ;)
make[1]: 离开目录“/data/redis-4.0.9/src”
执行make test 检测安装
make test
会得到如下结果提示“All tests passed without errors!”，表示make成功
93 seconds - integration/replication
94 seconds - unit/aofrw
105 seconds - integration/replication-3
57 seconds - unit/hyperloglog
60 seconds - unit/geo
116 seconds - unit/type/list-3
72 seconds - unit/obuf-limits
107 seconds - integration/replication-psync
\o/ All tests passed without errors!
Cleanup: may take some time... OK
make[1]: 离开目录“/data/redis-4.0.9/src”
2 启动：
安装完成后在src目录下会出现服务程序redis-server，按默认方式启动redis
[root@node02 redis-4.0.9]# src/redis-server
执行结果
[root@node02 redis-4.0.9]# src/redis-server

1.3 编译常见问题：
问题1： 缺少gcc依赖
/bin/sh:行1: cc：未找到命令
解决：
安装gcc依赖包
yum install gcc-c++ -y
问题2： 缺少jemalloc依赖
> In file included from adlist.c:34:
zmalloc.h:50:10: 致命错误：jemalloc/jemalloc.h：没有那个文件或目录
50 | #include <jemalloc/jemalloc.h>
| ^~~~~~~~~~~~~~~~~~~~~
错误原因：
redis默认要使用jemalloc作为内存分配器，单系统不具备，只有默认的libc；
解决方案有两种：
1. make命令指定libc：
make MALLOC=libc
2. 在系统中安装 jemalloc；
2.1 jemalloc 相对libc的好处：
① 减少内存碎片，提升内存使用效率；
② 多线程环境表现优异，有较高的并发性能；
③ 支持多种内存分配算法，可根据场景优化；
④ 对发内存分配表现较好；
2.2 jemalloc 安装：
1. 安装epel仓库
sudo yum install epel-release
2. 安装jemalloc
sudo yum install jemalloc-devel
问题3： 安装jemalloc 继续make出现问题（未解决！！）
注： 问题2 jemalloc 问题采用方案1：make MALLOC=libc 解决，可以避免这个问题；
/usr/bin/ld: 找不到 ../deps/hiredis/libhiredis.a: 没有那个文件或目录
/usr/bin/ld: 找不到 ../deps/lua/src/liblua.a: 没有那个文件或目录
collect2: 错误：ld 返回 1
