网站错误提示“Error establishing a Redis connection”怎么办？

#!/bin/bash

# 检测 redis 是否在运行
redis_status=$(systemctl is-active redis.service)

if [ "$redis_status" != "active" ]; then
    echo "Redis is not running. Restarting Redis..."
    systemctl start redis.service
    echo "Redis restarted."
fi

# 检测网站是否可访问
website_url="https://www.58588885.com"  # 替换为你要检测的网站 URL
http_status=$(curl -s -o /dev/null -w "%{http_code}" $website_url)

if [ "$http_status" != "200" ]; then
    echo "Website is not accessible. Restarting Redis..."
    systemctl restart redis.service
    echo "Redis restarted."
