出现错误：error_log(/www/wwwroot/******/runtime/log/202407/12.log): Failed to open stream: Permission denied

解决办法：需要修改两个位置，首先按找到thinkphp/library/log/driver/file.php

我的项目位置在vendor\topthink\framework\src\think\log\driver\File.php

有些项目可能会有think-log等文件，注意：是framework 目录

1.找到56行（不同tp版本可能会不一样，save方法中） !is_dir($path) && mkdir($path, 0755, true);

找到后修改这个方法。

/**
 * 日志写入接口
 * @access public
 * @param array $log 日志信息
 * @return bool
 */
public function save(array $log): bool
{
$destination = $this->getMasterLogFile();

$path = dirname($destination);
//!is_dir($path) && mkdir($path, 0777, true);
!is_dir($path) && mkdir($path, 0777, true) && chmod($path,0777);

$info = [];

// 日志信息封装
$time = \DateTime::createFromFormat('0.u00 U', microtime())->setTimezone(new \DateTimeZone(date_default_timezone_get()))->format($this->config['time_format']);

foreach ($log as $type => $val) {
$message = [];
foreach ($val as $msg) {
if (!is_string($msg)) {
$msg = var_export($msg, true);
}

$message[] = $this->config['json'] ?
json_encode(['time' => $time, 'type' => $type, 'msg' => $msg], $this->config['json_options']) :
sprintf($this->config['format'], $time, $type, $msg);
}

if (true === $this->config['apart_level'] || in_array($type, $this->config['apart_level'])) {
// 独立记录的日志级别
$filename = $this->getApartLevelFile($path, $type);
$this->write($message, $filename);
continue;
}

$info[$type] = $message;
}

if ($info) {
return $this->write($info, $destination);
}

return true;
}

2.找到128行（不同tp版本可能会不一样，write方法中）
return error_log($message, 3, $destination);

    /**
     * 日志写入
     * @access protected
     * @param array  $message     日志信息
     * @param string $destination 日志文件
     * @return bool
     */
    protected function write(array $message, string $destination): bool
    {
        // 检测日志文件大小，超过配置大小则备份日志文件重新生成
        $this->checkLogSize($destination);

        $info = [];

        foreach ($message as $type => $msg) {
            $info[$type] = is_array($msg) ? implode(PHP_EOL, $msg) : $msg;
        }

        $message = implode(PHP_EOL, $info) . PHP_EOL;

        //这个是修改之后的
        if (!is_file($destination)) {
            $first = true;
        }

        $ret = error_log($message, 3, $destination);
        try {
            if (isset($first) && is_file($destination)) {
                chmod($destination, 0777);
                unset($first);
            }
        } catch (\Exception $e) {

        }
        return $ret;
        //这段是之前的
        //return error_log($message, 3, $destination);
    }
