django-redis Error 111 connecting to 127.0.0.1:6379.

在 setting.py 中设置完了 django-redis 之后，在 view.py 中使用出现 error：

Error 111 connecting to 127.0.0.1:6379.

-> 参考

出现这个问题是因为服务器中的 redis sercive 没找到或者没开启

如果没安装服务器的话，安装 redis-server

Ubuntu: sudo apt-get install redis-server
sudo yum install redis

(venv) [root@localhost venv]# yum -y install redis

Installed:
  redis.x86_64 0:3.2.12-2.el7

Dependency Installed:
  jemalloc.x86_64 0:3.6.0-1.el7

Complete!

安装完之后记得打开 redis 服务

(venv) [root@localhost venv]# systemctl start redis
Redirecting to /bin/systemctl start redis.service

最后，记得设置开机启动，不然下次一重启就会报错

systemctl enable redis

查看是否重启

(venv) [hugin@localhost hugin]$ systemctl status redis

Loaded 所在行 显示 enables 即表示开机启动设置成功
