目录文件说明

redis-server.exe	服务端程序	提供redis服务
redis-cli.exe	客户端程序	通过它连接redis服务并进行操作
redis-check-dump.exe	本地数据库检查
redis-check-aof.exe	更新日志检查	用以模拟同时由N个客户端发送M个 SETs/GETs 查询 (类似于 Apache 的ab 工具)
redis-benchmark.exe	性能测试
redis.windows.conf	配置文件	将redis作为普通软件使用的配置，命令行关闭则redis关闭
redis.windows-service.conf	配置文件	将redis作为系统服务的配置，用以区别开两种不同的使用方式

测试

启动 redis

redis-server.exe redis.windows.conf

服务

• https://github.com/alfishe/redis-service

• https://github.com/kcherenkov/redis-windows-service

注册服务

redis-server.exe --service-install redis.windows.conf --loglevel verbose

删除服务

redis-server --service-uninstall

开启服务

redis-server --service-start

停止服务

redis-server --service-stop

重命名服务

redis-server --service-name name

redis-server --service-install --service-name redisService3 --port 10003
redis-server --service-start --service-name redisService3

可执行文件的路径

测试

set name value
get name

PHP

php.ini

extension=redis

示例

$redis = new Redis();

扩展安装

pecl install redis

可能的问题：

1. failed to run phpize

可能是 php.ini 禁用了 popen 函数

资源库模式

sudo yum install epel-release

sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

sudo yum-config-manager --enable remi-php74

# 安装PHP和PHP Redis扩展
sudo yum install php php-redis

# 仅安装
# yum -y install php-redis

systemctl restart php-fpm
sudo systemctl restart nginx

查找并杀死进程

ps aux | grep php-fpm
killall -9 php-fpm

测试安装是否成功

test.php

<?php
// 测试Redis扩展
if (extension_loaded('redis')) {
    echo "Redis extension is loaded!";
} else {
    echo "Redis extension is not loaded!";
}

配置

密码

配置文件

requirepass foobared

命令行

config set requirepass test123
config get requirepass

# 密码验证
auth test123

常见问题
