阿里云服务器安装Redis

$ wget http://download.redis.io/releases/redis-6.0.8.tar.gz
$ tar xzf redis-6.0.8.tar.gz
$ cd redis-6.0.8
$ make

安装过程中如果出现如下错误:

                                                                                              ^

出现上面错误的原因是redis6.0+以上安装需要gcc版本5.3及以上。

查看当前gcc版本

gcc -v

我们发现阿里云服务器上面，centos7系统gcc版本默认为4.8.5。

所以我们需要升级gcc版本。

//升级gcc到9以上
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

还需要执行下面命令，二者任选其一
//临时将此时的gcc版本改为9
scl enable devtoolset-9 bash
//或永久改变
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

执行完上述操作后，执行gcc -v命令，我们会发现gcc版本成功升级到了9.1.1。接下来我们继续执行make安装redis6.0+，应该就不会出现什么问题。

redis6.0+安装成功后，我们如何验证redis服务是否正常?

启动服务端
src/redis-server

如上图，我们发现redis服务已经正常启动了。

redis服务端已经启动成功，我们如何进行客户端连接呢?

Redis配置文件

位置:redis安装路径下面redis.conf文件

修改redis.conf配置文件

1.daemonize设置成yes

2.注释掉bind 127.0.0.1 添加bind 0.0.0.0

3.protected-mode yes 改为 protected-mode no

 配置阿里云安全组规则

 经过上述的配置，我们现在完全可以使用redis客户端进行连接我们的阿里云上面的redis服务了。

Redis客户端

Redis客户端我推荐大家使用AnotherRedisDesktopManager这个开源工具。

AnotherRedisDesktopManager地址

https://github.com/qishibo/AnotherRedisDesktopManager

 AnotherRedisDesktopManager支持通过工具直接打开redis命令客户端。

Python连接Redis

import redis

pool = redis.ConnectionPool(host='xxx', port='6379', decode_responses=True)
r = redis.Redis(host='xxx', port='6379', decode_responses=True, password='xxx')
print(r.get('name'))

 Java连接Redis

import redis.clients.jedis.Jedis;

public class RedisTest {
    public static void main(String[] args) {
        Jedis jedis = new Jedis("xxx", 6379);
        jedis.auth("root");
        System.out.println("连接成功");
        //查看服务是否运行
        System.out.println("服务正在运行: " + jedis.ping());
        System.out.println("redis 存储的字符串为: " + jedis.get("name"));
    }
}
