1.安装gcc tcl

sudo yum -y install gcc tcl

2. 解压redis包，解压后的目录如下：

3. 到deps目录下编译 jemalloc，lua，linenoise，hiredis

make jemalloc lua linenoise hiredis

4.到redis的根目录下执行make

5.安装到指定位置：

make PREFIX=/opt/cdh5.15.0/redis install

6. redis目录：

7.设置环境变量：

export REDIS_HOME=/opt/cdh5.15.0/redis
export PATH=$PATH:$REDIS_HOME/bin

别忘了还要：

source /etc/profile

8. 将redis改为service：

切换为root用户，到目录/opt/cdh5.15.0/redis-2.8.18/utils目录下：

执行：

./install_server.sh

[root@slave2 utils]# ./install_server.sh

Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf

9.进入/etc/init.d目录下：

[root@slave2 utils]# cd /etc/init.d/
[root@slave2 init.d]# ll
total 44
-rw-r--r--. 1 root root 17500 May  3  2017 functions
-rwxr-xr-x. 1 root root  4334 May  3  2017 netconsole

将redis_6379改为redisd

设置开机启动服务：

systemctl enable redisd

启动并查看:

[root@slave2 init.d]# chkconfig redisd
[root@slave2 init.d]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
You have new mail in /var/spool/mail/root
