sphinx系列之sphinx安装和运行测试(二)

时间：2010-11-04 来源：Done

进入到sphinx的源码文件夹里，运行下列命令就可以安装sphinx了：

ldconfig /usr/local/mysql/lib/mysql
ldconfig /usr/local/mysql/include/mysql
./configure --prefix=/usr/local/sphinx --with-mysql=/usr/local/mysql
make && make install

其中--prefix是指向sphinx的安装路径，--with-mysql是指向mysql的安装路径。如果上面都没有报错，那sphinx就成功安装了。

sphinx的配置文件为sphinx.conf，下面进行配置：

cd /usr/local/sphinx/etc
cp sphinx.conf.dist sphinx.conf
vim sphinx.conf

进入/usr/local/sphinx/etc文件夹下，看到该文件夹下有下面这些文件：

-rw-r--r-- 1 root root 905 11-04 13:32 example.sql
-rw-r--r-- 1 root root 19003 11-04 13:32 sphinx.conf.dist
-rw-r--r-- 1 root root 948 11-04 13:32 sphinx-min.conf.dist

把sphinx.conf.dist复制出来成sphinx.conf，并进入修改它的一些数据库的配置，主要是修改数据库地址，数据库用户、密码，还有数据库名这些，这里我们用安装mysql自带的test库进行测试。

运行该目录下的example.sql脚本，把数据导到数据库中：

mysql -u mysql < /usr/local/sphinx/etc/example.sql

然后进入mysql中查看添加的数据：

mysql  #进入mysql
show databases;# 查看到有下面这些库
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| test               |
+--------------------+
3 rows in set (0.00 sec)

＃进入test库，查看到有下面这些表，其中documents表是自动导进来的：
mysql> use test
Database changed
mysql> show tables;
+----------------+
| Tables_in_test |
+----------------+
| documents      |
| eht_articles   |
| tags           |
+----------------+
3 rows in set (0.01 sec)

查询documents表就能看到下面记录：
mysql> SELECT * FROM documents;
+----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+
| id | group_id | group_id2 | date_added          | title           | content                                                                   |
+----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+
|  1 |        1 |         5 | 2010-11-04 19:22:13 | test one        | this is my test document number one. also checking search within phrases. |
|  2 |        1 |         6 | 2010-11-04 19:22:13 | test two        | this is my test document number two                                       |
|  3 |        2 |         7 | 2010-11-04 19:22:13 | another doc     | this is another group                                                     |
|  4 |        2 |         8 | 2010-11-04 19:22:13 | doc number four | this is to test groups                                                    |
+----+----------+-----------+---------------------+-----------------+---------------------------------------------------------------------------+
4 rows in set (0.00 sec)

sphinx的配置文件也创建完了，数据也导进去了，接下来就用下面命令来创建索引：

/usr/local/sphinx/bin/indexer

创建索引是报了一个这样的错误：/usr/local/sphinx/bin/indexer: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory，主要原因是在上一篇中安装完mysql后没有设置环境变量，可以用下面方法解决：

locate libmysqlclient #运行该命令找到关于libmysqlclient.so.16的文件
cp /usr/local/mysql/lib/mysql/libmysqlclient.so.16 /usr/lib/libmysqlclient.so.16 ＃然后把该文件的一个连接复制到在环境变量的文件夹/usr/lib/下

再次运行创建索引命令就能完成索引的创建了。

然后用下面命令进行搜索测试：

/usr/local/sphinx/bin/search test

但此时报了一个search error: failed to open /usr/local/sphinx/var/data/test1.sph: No such file or directory.这样的错误，网上找了一下解决方法是在创建索引是加上--all参数，也就是：

/usr/local/sphinx/bin/indexer --all

--all参数官方文档的说明是：

--all tells indexer to update every index listed in sphinx.conf, instead of listing individual indexes. This would be useful in small configurations, or cron-type or maintenance jobs where the entire index set will get rebuilt each day, or week, or whatever period is best. Example usage

重新创建索引后再次运行测试 /usr/local/sphinx/bin/search test 就会出现下列结果：

sphinx的安装和运行测试已完，下次讲sphinx的中文分词和python调用。
