sphinx Introduction and installation of sphinx

Introduction

Background:

1. Large amount of data, content review, existing search resume index is slow; staff turnover, existing search is difficult to maintain

2. Front-end calls are complex; full table scan is used, search speed is slow; the results are There is no sorting; it is difficult to find the most accurate data as quickly as possible

Suggested optimization:

1. High-speed index creation

2. Avoid doing like operations on the database and reduce pressure

3. Sort the search results by weight

4. Front-end development is easy to call

5. It is best to have a low threshold, easy to master and maintain in the future

Installation

1. Install the lamp environment

If you have already installed it, skip this step.
2. Download the required files
Note: If you use Ubuntu 10.10 (sphinxsearch), you can use apt-get install to install directly, you can skip this step (but Chinese word segmentation is not supported)
Coreseek Fulltext Server (source code): http://www.coreseek.cn/uploads/csft/3.1/Source/csft-3.1.tar.gz
Coreseek Mmseg (source code): http://www.coreseek.cn/uploads/csft/3.1/Source /mmseg-3.1.tar.gz
3. Tools must be installed
sudo apt-get install autoconf automake autotools-dev cpp curl gawk gcc lftp libc6-dev linux-libc-dev make libpcre3-dev libpcrecpp0 g++ libtool libncurses5-dev
sudo aptitude install libmysql++-dev libmysqlclient15-dev checkinstall
4. Install mmseg
sudo su
tar zxvf mmseg-3.1.tar.gz
mkdir /usr/local/mmseg
cd mmseg-3.1
./configure --prefix=/usr /local/mmseg
make
make install
5. Install sphinx
Note: If you use Ubuntu 10.10 (sphinxsearch), you can use sudo apt-get install sphinxsearch to quickly install (but Chinese word segmentation is not supported)
If not, use the following Command:
(If you are installing mysql manually below, please change --with-mysql to your corresponding mysql installation directory)
tar zxvf csft-3.1.tar.gz
mkdir /usr/local/coreseek
cd csft-3.1
./configure --prefix=/usr/local/coreseek --with-mysql --with-mmseg-includes=/usr/local/mmseg/include/mmseg --with-mmseg-libs=/usr/local/ mmseg/lib/
make clean
make
make install
6. Test
The installation is complete, the following is the test.
Note: If you use Ubuntu 10.10 (sphinxsearch), the following configuration file sphinx.conf.dist should be in /etc/sphinxsearch Directory
cd /usr/local/coreseek/etc
sudo cp sphinx.conf.dist sphinx.conf
sudo vim sphinx.conf (modification example is as follows)
mysql -uroot test Note: If you use Ubuntu 10.10 (sphinxsearch), below you can directly use the commands sudo indexer --all and sudo search test
sudo /usr/ local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all
sudo /usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/sphinx.conf test

sudo /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/sphinx.conf (start searchd process for sphinxapi call)

Note: If you use Ubuntu 10.10 (sphinxsearch ), the following parameters should be modified as follows:
path = /var/lib/sphinxsearch/data/idxbook1
log = /var/log/sphinxsearch/searchd.log
query_log = /var/log/sphinxsearch/query. log
pid_file = /var/run/searchd.pid
Also, the charset_dictpath and charset_table parameters will not be supported, that is, Chinese word segmentation will not be supported

The above introduces the introduction and installation of sphinx, including sphinx content. I hope it will be helpful to friends who are interested in PHP tutorials.
