无法使用 PHP 和 PDO 连接到 Sphinx

Question

我似乎遇到了我不明白的问题...

我已经安装了MySQL8.0.27 我已经安装了 Sphinx，创建了一个索引，填充了它，通过终端一切正常。能够毫无问题地查询 Spinx 索引。所以 searchd 和索引器正在做他们的工作。

我创建了一个简单的 PHP 界面来使用 PHP 搜索此索引。但这就是事情变得奇怪的地方......

我无法连接到 sphinx 实例（它确实通过终端工作..）--> SQLSTATE[HY000] [2002] 权限被拒绝

我的sphinx.conf

source page
{
        type = mysql

        sql_host = localhost
        sql_db   = db
        sql_user = user
        sql_pass = password
        sql_port = 3306

        sql_query = SELECT p.id, p.parent_id, p.date_add, p.version, p.content, p.pagenumber, p.status, pp.filename, pp.pages  FROM page p LEFT JOIN parent_page pp ON p.parent_id=pp.id

        sql_field_string = content
}

index pagedata
{
        source = wob
        path = /etc/sphinx/data/page
        morphology = none

        min_word_len = 2
        min_prefix_len = 0
}

searchd
{
    listen = 9312
    listen = 9306:mysql41
    log = /var/log/sphinx/searchd.log
    query_log = /var/log/sphinx/query.log

    read_timeout = 5
    max_children = 30
        pid_file                = /etc/sphinx/sphinx-searchd.pid
        seamless_rotate         = 1
        preopen_indexes         = 1
        unlink_old              = 1
        workers                 = threads # for RT to work
        binlog_path             = /var/log/sphinx/
}

这是狮身人面像状态

这是我用于从我的 PHP 脚本连接到 Sphinx 的代码...这导致了此 post...

顶部提到的错误

<?php
try {
    $pdo = new PDO("mysql:host=localhost:9306");
    // set the PDO error mode to exception
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->exec('SET NAMES utf8');
} catch (PDOException $e) {
    echo "Connection failed to API database: " . $e->getMessage();
}

通过终端连接没问题，查询运行良好且快速...

$pdo = new PDO() 部分失败。无法建立连接。我尝试用 127.0.0.1 替换 localhost，尝试将端口替换为 9312（参见配置）以及这些之间的所有组合。没有骰子。

有人有线索或提示吗？这让我发疯...

Answer 1

刚刚安装了 Manticore Search 4.2，它遇到了完全相同的问题...这让我开始思考。

原来是因为 SELinux...This post 有适合我的解决方案。所以它与 Sphinx 或 Manticore Search 无关...是我的 SELinux 设置阻止我从 http 用户建立数据库连接。

答案有 4 个简单的步骤来永久允许，一切都非常有效！
