记一次迁移服务器后，Laravel6.5 redis队列不执行的解决经过

今天遇到一个棘手的问题，将原centos7.4系统迁移到新服务器上，新服务器为centos7.7，宝塔面板，环境和原系统一样，但laravel上传视频添加到队列转码时，却不执行，日志也没有任何记录。

首先查检配置，发现predis没有安装，于是先安装predis：

composer require predis/predis

再测试队列，还是不执行，也没有任何日志记录和报错信息，只能慢慢核对配置文件，相关配置文件如下：

config/database.php

use Illuminate\Support\Str;

项目根目录的.env文件，也没发现问题：

//缓存配置
BROADCAST_DRIVER=log
CACHE_DRIVER=redis
QUEUE_CONNECTION=redis
SESSION_DRIVER=redis
SESSION_LIFETIME=120
SESSION_CONNECTION=redis-session
//REDIS数据库配置
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379
REDIS_CLIENT=predis

后来想起，在阿里云盾里有个安全加固，修改了redis的配置，查看redis的日志，果然发现了问题：

[2019-11-09 18:35:18] local.ERROR: ERR unknown command `EVAL`, with args beginning with: `-- Get all of the jobs with an expired "score"... local val = redis.call('zrangebyscore', KEYS[1], '-inf', ARGV[1])  -- If we ha`,  {"exception":"[object] (Predis\\Response\\ServerException(code: 0): ERR unknown command `EVAL`, with args beginning with: `-- Get all of the jobs with an expired \"score\"... local val = redis.call('zrangebyscore', KEYS[1], '-inf', ARGV[1])  -- If we ha`,  at /www/wwwroot/blog.dzbfsj.com/vendor/predis/predis/src/Client.php:370)

百度一下，马上找到了解决办法：

redis客户端使用evel命令，报ERR unknown command 'EVAL'

解决方式：

检查redis版本是否大于等于2.6.0

如果版本没问题，打开redis.conf配置文件

检查是否有rename-command EVAL ""这项配置

如果有，注释掉#rename-command EVAL ""，重启redis即可

于是找到阿里云后台云安全中心，后台提供的加固redis的方法：

后台提供的方法是修改 redis.conf 文件，添加

rename-command FLUSHALL ""
rename-command FLUSHDB  ""
rename-command CONFIG   ""
rename-command KEYS     ""
rename-command SHUTDOWN ""
rename-command DEL ""
rename-command EVAL ""

果然是这个优化导致的问题，果断删除这几行代码，重新启动redis，测试队列一切正常。
