阿里云部署redis服务器，以及远程访问

准备工作：

我的系统是CentOS 7.

先去官网下合适的版本 https://redis.io/download

解压并进入安装目录

编译安装:

make

cd src

make test

设置路径 make install PREFIX=/usr/local/redis

将配置文件移动到redis目录

修改redis.conf

1、默认情况Redis不是在后台运行，我们需要修改把redis放在后台运行：daemonize yes

2、redis安全策略默认本机访问，所以远程访问的话需要将 bind 127.0.0.1加#注释掉

仅仅注释掉这些还不行，因为新版本增加了保护模式，具体提示信息

DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

虽然可以将保护模式设为no来关闭，但为了安全还是推荐设权限密码：

找到这一行# requirepass foobared，将#去掉并把foobared改成你的密码

3、让redis开机自启
打开/etc/rc.local
加入/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis-conf

启动redis服务
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

配置阿里云安全策略

python环境测试：

pip redis
