安裝gcc:
yum install gcc
驗證gcc安裝位置:
[root@devmaster opt]# whereis gcc gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

清空之前安裝的錯誤編譯信息：make distclean
重新編譯：Make
重新安裝：
[root@devmaster redis-3.2.7]# make cd src && make all make[1]: Entering directory `/opt/redis-3.2.7/src' …… LINK redis-check-aof Hint: It's a good idea to run 'make test' ;) make[1]: Leaving directory `/opt/redis-3.2.7/src'
運行redis：

看到最後的倆行，表示安裝成功。
第一個警告：The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
意思是：TCP backlog設置值，511沒有成功，因爲 /proc/sys/net/core/somaxconn這個設置的是更小的128.
臨時解決方法：（即下次啓動還需要修改此值）
echo 511 > /proc/sys/net/core/somaxconn
永久解決方法：（即以後啓動還需要修改此值）
將其寫入/etc/rc.local文件中。
baklog參數實際控制的是已經3次握手成功的還在accept queue的大小。
第二個警告：overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to/etc/sysctl.conf andthen reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
意思是：overcommit_memory參數設置爲0！在內存不足的情況下，後臺程序save可能失敗。建議在文件 /etc/sysctl.conf 中將overcommit_memory修改爲1。
臨時解決方法：echo "vm.overcommit_memory=1" > /etc/sysctl.conf
永久解決方法：將其寫入/etc/sysctl.conf文件中。
參考：有關linux下redis overcommit_memory的問題
第三個警告：you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix thisissue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain thesetting after a reboot. Redis must be restarted after THP is disabled.
意思是：你使用的是透明大頁，可能導致redis延遲和內存使用問題。執行 echo never > /sys/kernel/mm/transparent_hugepage/enabled 修復該問題。
臨時解決方法：
echo never > /sys/kernel/mm/transparent_hugepage/enabled。
永久解決方法：
將其寫入/etc/rc.local文件中。
參考透明大頁介紹。
測試：
[root@devmaster src]# cd src [root@devmaster src]# ./redis-cli redis-cli -h 10.168.85.25 -p 6379

很有意思的是，命令行中也有命令提示(可以看最後一行淺灰色的，就是輸入一個set之後，自動顯示的提示信息)
