折腾:

[已解决]Flask中添加后台进程用于提醒到期时发送通知

此时,需要去在CentOS中,安装redis

用于后续Flask中的开发。

Flask 如何安装  redis

Redis

Flask环境安装 | 大树小屋

用yum去安装了redis,又去删除了,因为发现版本太低:

只有2.4.10

而官网的:

Redis

最新版本是:

3.2.3

再去运行试试,结果出错:

Flask-And-Redis — Flask-And-Redis 0.6 documentation

Getting started with Flask, Redis and wercker

[已解决]redis安装后去make test出错:You need tcl 8.5 or newer in order to run the Redis test

[已解决]安装完毕redis后出错:Warning: no config file specified using the default config

https://www.crifan.com/installed_redis_warning_no_config_file_specified_using_the_default_config

[已解决]运行redis-server出错:Creating Server TCP listening socket 6379 unable to bind socket

[总结]

去官网:

Redis

参考:

Redis Quick Start – Redis

去:

1.从源码下载和安装

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make
yum install -y tcl
make test
make install

说明:

(1)其中make test是可选的

(2)安装tcl是为了make test

2.设置配置文件后再去运行

mkdir /etc/redis
cp redis.conf /etc/redis
redis-server /etc/redis/redis.conf

说明:

1.运行cp redis.conf /etc/redis之前,确保是在redis的源码目录下,因为其下有个默认的配置文件redis.conf

2.此处直接使用redis-server,而不是:src/redis-server,是因为:

上面的make install时已经把redis-server拷贝到PATH环境变量所包含的路径:/usr/local/bin/中去了,所以命令行中可以直接使用redis-server
