sphinx系列之sphinx安装和运行测试(二)

在上一篇文章中说到安装mysql和sphinx的mysql引擎sphinxSE的安装，这一篇说的是sphinx的安装和运行测试，关于下载和解压缩sphinx都用上一篇文章里说的。

     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：
