emm.. 最新的已经到了5.0.6，我们要跟得上时代，就测试安装5.0.6

修改系统参数

echo "vm.overcommit_memory = 1 " >>/etc/sysctl.conf`
sysctl –p  //生效

该配置参数的含义：
/proc/sys/vm/overcommit_memory文件指定了内核针对内存分配的策略，其值可以是0、1、2。
0 表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。
1 表示内核允许分配所有的物理内存，而不管当前的内存状态如何。
2 表示内核允许分配超过所有物理内存和交换空间总和的内存。
解压tar包，将解压出来的目录移至预定目录

tar xzf redis-5.0.6.tar.gz
mv redis-5.0.6 /var/redis-5.0.6

创建相关目录

mkdir -p /var/redis-5.0.6/run
mkdir -p /var/redis-5.0.6/tmp
mkdir -p /var/redis-5.0.6/log
mkdir -p /var/redis-5.0.6/etc
mkdir -p /var/redis-5.0.6/database

复制配置文件模板

cp /var/redis-5.0.6/redis.conf /var/redis-5.0.6/etc/

启动redis服务http://www.cndba.cn/asker/article/3768

/var/redis-5.0.6/src/redis-server /var/redis-5.0.6/etc/redis_6379.conf

配置环境变量

vim ~/.bash_profile

PATH=/var/redis-5.0.6/bin/:$PATH:$HOME/bin
source ~/.bash_profile //生效
