$ wget http://download.redis.io/releases/redis-5.0.5.tar.gz
$ tar xzf redis-5.0.5.tar.gz
$ cd redis-5.0.5
$ make

make完后 redis-5.0.5目录下会出现编译后的redis服务程序redis-server，还有用于测试的客户端程序redis-cli，两个程序位于安装目录 src 目录下：

下面启动redis服务。

2
$ cd src
$ ./redis-server

注意这种方式启动redis 使用的是默认配置。也可以通过启动参数告诉redis使用指定配置文件使用下面命令启动。

1
2
$ cd src
$ ./redis-server ../redis.conf

redis.conf 是一个默认的配置文件。我们可以根据需要使用自己的配置文件。

启动redis服务进程后，就可以使用测试客户端程序redis-cli和redis服务交互了。 比如：

$ cd src
$ ./redis-cli
redis> set foo bar
OK
redis> get foo
"bar"

# 安装到 /usr/local/redis

installpath=/usr/local/redis
mkdir -p $installpath
cd redis-5.0.5
make MALLOC=libc
make PREFIX=$installpath install
\cp -f redis.conf $installpath

功能测试（耗时较长，非必须执行）

在安装成功之后，可以运行测试，确认Redis的功能是否正常
[root@localhost ~]# make test

出现报错：
hadoop@stormspark:~/workspace/redis2.6.13/src$ make test
You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] Error 1

解决方式
yum install -y tcl

重新执行测试
[root@localhost ~]# make test

......

\o/ All tests passed without errors!

Cleanup: may take some time... OK

修改配置文件

sed -i '/^logfile/clogfile "'$installpath'/redis.log"' "$installpath/redis.conf"

[root@localhost ~]# chown -R redis.redis /usr/local/redis

启动并设置开机自启
[root@localhost ~]# systemctl start redis
[root@localhost ~]# systemctl enable redis
