一鍵編譯安裝Redis-4.0.14，實現systemctl啓動

一鍵編譯安裝腳本以下：

yum ×××tall gcc jemalloc-devel wget -y &>/dev/null #初始化安裝環境
cd /usr/local/src/
wget http://download.redis.io/releases/redis-4.0.14.tar.gz &>/dev/null
tar xvf redis-4.0.14.tar.gz 
cd redis-4.0.14/deps/
make hiredis jemalloc linenoise lua #若無此步驟，有的主機可能安裝不成功
cd ..
make PREFIX=/apps/redis ×××tall #安裝目錄
mkdir /apps/redis/{etc,run,data,logs} #建立文件目錄
cp /usr/local/src/redis-4.0.14/redis.conf /apps/redis/etc/ #複製配置文件
ln -sv /apps/redis/bin/redis-* /usr/sbin/ #建立命令軟連接

touch /usr/lib/systemd/system/redis.service #建立systemctl啓動腳本
cat >  /usr/lib/systemd/system/redis.service <<EOF
