linux 安装redis过程中出现了异常，make不通过，异常如下：
[root@localhost redis-2.8.3]# make
cd src && make all
make[1]: 进入目录“/usr/local/services/redis/redis-2.8.3/src”

make[1]: *** [adlist.o] 错误 127
make[1]: 离开目录“/usr/local/services/redis/redis-2.8.3/src”
make: *** [all] 错误 2
提示：gcc 命令未找到
使用命令安装一下就可以解决了：
yum install -y gcc g++ gcc-c++ make
解决了上面问题后，又出现如下问题：
root@localhost redis-2.8.3]# make cd src && make all make[1]: 进入目录“/usr/local/services/redis/redis-2.8.3/src” CC adlist.o In file included from adlist.c:34:0: zmalloc.h:50:31: 致命错误：jemalloc/jemalloc.h：没有那个文件或目录 #include <jemalloc/jemalloc.h> ^ 编译中断。 make[1]: *** [adlist.o] 错误 1 make[1]: 离开目录“/usr/local/services/redis/redis-2.8.3/src” make: *** [all] 错误 2
继续填坑，解决方案，如下：
[root@localhost redis-2.8.3]# make MALLOC=libc
最后，终于把redis服务启动起来了：
[root@localhost src]# ./redis-server
