一、安装wget

    [root@localhost redis-3.2.9]# yum install wget

二、获取redis压缩包

    [root@localhost redis-3.2.9]# wget http://download.redis.io/releases/redis-3.2.9.tar.gz

三、解压压缩包

    [root@localhost redis-3.2.9]# tar -xzf redis-3.2.9.tar.gz

四、编译

   [root@localhost redis-3.2.9]# cd redis-3.2.9

    [root@localhost redis-3.2.9]# make

    make[3]: gcc：命令未找到

报错：gcc：命令未找到

五、安装gcc

    [root@localhost redis-3.2.9]# yum install gcc

    [root@localhost redis-3.2.9]# make
    make[1]: Entering directory `/usr/document/program/redis-3.2.9/src'CC adlist.o
    在包含自 adlist.c：34 的文件中:
    zmalloc.h:50:31: 错误：jemalloc/jemalloc.h：没有那个文件或目录
    zmalloc.h:55:2: 错误：#error "Newer version of jemalloc required"

原因：libc 并不是默认的 分配器， 默认的是 jemalloc。但是又没有jemalloc 而只有 libc 当然 make 出错

解决方案：make MALLOC=libc

六、编译

[root@localhost redis-3.2.9]# make MALLOC=libc
cd src && make all
make[1]: Entering directory `/usr/document/program/redis-3.2.9/src'
rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-rdb redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html
(cd ../deps && make distclean)
make[2]: Entering directory `/usr/document/program/redis-3.2.9/deps'
(cd hiredis && make clean) > /dev/null || true
(cd linenoise && make clean) > /dev/null || true
(cd lua && make clean) > /dev/null || true
(cd geohash-int && make clean) > /dev/null || true
(cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true
(rm -f .make-*)

七、启动

[root@localhost src]# ./redis-server

1987:M 15 Jul 00:03:35.539 # Server started, Redis version 3.2.9

八、允许外网访问

修改redis.conf

1.将bind 127.0.0.1注释
2.将protected-mode yes改为no
3../redis-server ../redis.conf
