linux sphinx,linux下正确安装sphinx-for-chinese中文全文索引
sphinx-for-chinese是一款专注于中文搜索的全文检索软件，在sphinx的基础上添加了中文处理模块并优化了中文搜索效果。
windows上安装sphinx请移步 http://www.tigerbook.cn/article-127.html
#### 准备工作
Linux安装sphinx需要先安装mysql和Gcc和g++支持
```
yum install gcc
yum install g++
```
在linux下，C++的编译器不是g++这个名称，而是gcc-c++，由此看来的确是我想当然了。然后直接运行
```
yum install gcc-c++ libstdc++-devel
```
#### 下载安装
首先下载 sphinx-for-chinese.tar.gz 放在/usr/local 目录下并且解压
```
cd /usr/local
wget http://sphinxsearchcn.github.io/downloads/sphinx-for-chinese-2.2.1-dev-r4311.tar.gz
```
解压之后重命名为sphinxforchinese，进入sphinxforchinese目录开始执行安装
```
tar zxvf sphinx-for-chinese-2.2.1-dev-r4311.tar.gz
cd sphinxforchinese
./configure --prefix=/usr/local/sphinxforchinese --with-mysql
make
make install
```
#### 生成字典
先进入到 /usr/local/sphinxforchinese
1、将文件夹中的 xdict_1.1.txt ([点击下载](http://tigerbook.cn/demo/xdict_1.1.tar.gz "xdict_1.1.tar.gz"))文件丢到 /usr/local/sphinxforchinese目录下
2、执行命令
```
/usr/local/sphinxforchinese/bin/mkdict xdict_1.1.txt etc/xdict
```
成功后发现/usr/local/sphinxforchinese/etc/文件夹中有 xdict代表成功
#### 建立索引
将 sphinx.conf 丢到 /usr/local/sphinxforchinese/etc 中并且配置数据库连接信息
```
/usr/local/sphinxforchinese/bin/indexer -c /usr/local/sphinxforchinese/etc/sphinx.conf --all --rotate
```
sphinx.conf 文件信息如下
```
source main{
type = mysql
sql_host = 127.0.0.1
sql_user = yourusername #数据库用户名
sql_pass = yourpassword #数据库密码
sql_db = yourdb #使用数据库
sql_port = 3306
sql_sock=/tmp/mysql.sock #mysql文件
sql_query_pre = SET NAMES utf8
sql_query = \
SELECT id, sid,title, img_cover,url_link,updatetime FROM blog_test
sql_attr_uint = sid
sql_attr_timestamp = updatetime
}
source src1throttled : main{
}
index testindex{
source=main
path=/usr/local/sphinxforchinese/data/testindex
charset_type = utf-8
chinese_dictionary = /usr/local/sphinxforchinese/etc/xdict
}
indexer{
mem_limit = 256M
}
searchd
{
listen = 9312
listen = 9306:mysql41
log = /usr/local/sphinxforchinese/log/searchd.log
query_log = /usr/local/sphinxforchinese/log/query.log
read_timeout = 5
max_children = 30
pid_file = /usr/local/sphinxforchinese/log/searchd.pid
seamless_rotate= 1
preopen_indexes= 1
unlink_old = 1
workers = threads # for RT to work
binlog_path = /usr/local/sphinxforchinese/data
}
```
#### 启动sphinx
```
/usr/local/sphinxforchinese/bin/searchd -c /usr/local/sphinxforchinese/etc/sphinx.conf
```
#### 查看是否成功
检查 /usr/local/sphinxforchinese/var/data 中是否有 newindex开头的几个文件
