我是否需要为mysql重新安装思维狮身人面像，如果它以前安装了postgres？

Question

我为一个postgres项目安装了几个月的sphinx，现在我有一个使用mysql的项目。我试着用这条线在我environments.rb来解决这个问题：

ThinkingSphinx.database_adapter = :mysql 

，我甚至产生了这个项目development.sphinx.conf：

source article_core_0 
{ 
    type = mysql 
    sql_host = localhost 
    sql_user = *** 
    sql_pass = *** 
    sql_db = ***_development 
    sql_sock = /tmp/mysql.sock 
    sql_query_pre = UPDATE `articles` SET `delta` = 0 WHERE `delta` = 1 
    sql_query_pre = SET NAMES utf8 
    sql_query_pre = SET TIME_ZONE = '+0:00' 
    sql_query = SELECT SQL_NO_CACHE `articles`.`id` * 6 + 0 AS `id` , `articles`.`title` AS `title`, `articles`.`content` AS `content`, GROUP_CONCAT(DISTINCT IFNULL(`tags`.`tag`, '0') SEPARATOR ' ') AS `tag`, GROUP_CONCAT(DISTINCT IFNULL(`customer_categories`.`name`, '0') SEPARATOR ' ') AS `category`, CONCAT_WS(' ', `users`.`first_name`, `users`.`last_name`) AS `created_by_user_name`, `articles`.`id` AS `sphinx_internal_id`, 3448190970 AS `class_crc`, 0 AS `sphinx_deleted`, `articles`.`account_id` AS `account_id`, `articles`.`internal_only` AS `internal_only`, UNIX_TIMESTAMP(`articles`.`created_at`) AS `created_at`, UNIX_TIMESTAMP(`articles`.`updated_at`) AS `updated_at`, `articles`.`views` AS `views` FROM `articles` LEFT OUTER JOIN `articles_tags` ON `articles_tags`.`article_id` = `articles`.`id` LEFT OUTER JOIN `tags` ON `tags`.`id` = `articles_tags`.`tag_id` LEFT OUTER JOIN `articles_categories` ON `articles_categories`.`article_id` = `articles`.`id` LEFT OUTER JOIN `customer_categories` ON `customer_categories`.`id` = `articles_categories`.`customer_category_id` LEFT OUTER JOIN `users` ON `users`.`id` = `articles`.`created_by_id` WHERE (`articles`.`id` >= $start AND `articles`.`id` <= $end AND `articles`.`delta` = 0) GROUP BY `articles`.`id`, `articles`.`title`, `articles`.`content`, `users`.`first_name`, `users`.`last_name`, `articles`.`id`, `articles`.`account_id`, `articles`.`internal_only`, `articles`.`created_at`, `articles`.`updated_at`, `articles`.`views` ORDER BY NULL 
    sql_query_range = SELECT IFNULL(MIN(`id`), 1), IFNULL(MAX(`id`), 1) FROM `articles` WHERE `articles`.`delta` = 0 
    sql_attr_uint = sphinx_internal_id 
    sql_attr_uint = class_crc 
    sql_attr_uint = sphinx_deleted 
    sql_attr_uint = account_id 
    sql_attr_uint = views 
    sql_attr_bool = internal_only 
    sql_attr_timestamp = created_at 
    sql_attr_timestamp = updated_at 
    sql_query_info = SELECT * FROM `articles` WHERE `id` = (($id - 0)/6) 
} 

问题是我不断收到此错误：

Sphinx 0.9.9-rc2 (r1785) 
Copyright (c) 2001-2009, Andrew Aksyonoff

对此有何帮助？

看起来你已经编译Sphinx来支持PostgreSQL，而不是MySQL。所以你需要重新编译并重新安装Sphinx。你不需要在Thinking Sphinx中改变任何东西，这只是修改你的database.yml（我猜你已经完成了），你应该没问题。

请记住，默认情况下，Sphinx仅编译MySQL支持。我通常编译为MySQL和PostgreSQL和我的配置要求，从狮身人面像源目录中看起来类似：

./configure --with-pgsql 

希望这是所有的需要 - 除非你有MySQL的一个非标准的位置设置，那么您可能需要检查其他标志 - 运行./configure --help以查看各种选项。
