[大数据]error while loading shared libraries，error MISCONF Redis is configured to，redis get中文乱码

1、运行程序链接hiredis出现错误

error while loading shared libraries:
libhiredis.so.0.13: cannot open shared object file: No such file or directory
birdbird@birdbird-virtual-machine:~$ sudo su
[sudo] birdbird 的密码： 
root@birdbird-virtual-machine:/home/birdbird# vi /etc/ld.so.conf //打开这个文件
然后加入/usr/local/lib 保存退出。
root@birdbird-virtual-machine:/home/birdbird# /sbin/ldconfig //执行这个命令

再去运行程序就好啦~

2、config set stop-writes-on-bgsave-error no //执行这个命令

127.0.0.1:6379> setex aa 10 aa

127.0.0.1:6379> exit   //第一步
