Manticore Search是sphinx的分支开发版本，比sphinx的bug更少，使用更简单，且可以实现实时搜索，支持SNIPPET语法，还有很多高级用法，请至官方网站浏览manticoresearch.com
Manticore search支持以下centos/RHEL的32位和64位系统
CentOS 6 and RHEL 6
CentOS 7 and RHEL 7
CentOS 8 and RHEL 8
老牛最开始是在博客上使用了，参照本站搜索页面的高级搜索功能
最近一个WordPress站点准备上Manticore search，系统采用的是CentOS 6.8 64位，以下为安装过程记录
一、添加必要的环境组件
1 | yum install mysql-libs postgresql-libs expat unixODBC -y |
注意，对于要使用的源类型，一般只需要lib。如果您计划只从mysql数据库创建索引，那么安装mysql libs就足够了。如果您根本不打算使用“indexer”工具（创建索引的工具），则不需要安装这些软件包。
安装完成如下：
如果需要ICU开发包支持，需要额外安装以下包，本教程不安装
1 | yum install libicu -y |
二、安装Manticore Search有两种方法：
1、通过yum安装（本次教程，采用方式）
1 | yum install https://repo.manticoresearch.com/manticore-repo.noarch.rpm -y |
1 | yum install manticore -y |
安装完成后

To start Manticore Search service:
> service manticore start/stop
Configuration file:
/etc/manticoresearch/manticore.conf
Verifying : manticore-3.4.0_200327.b212975-1.el6.x86_64 1/1
Installed:
manticore.x86_64 0:3.4.0_200327.b212975-1.el6
2、通过rpm进行安装
1 | wget https://github.com/manticoresoftware/manticoresearch/releases/download/3.4.0/manticore-3.4.0_200327.b212975-1.el7.centos.x86_64.rpm |
1 | rpm -Uhv manticore-3.4.0_200327.b212975-1.el7.centos.x86_64.rpm |
三、新版Manticore Search控制命令
以默认配置启动Manticore Search服务
centos7
1 | systemctl start manticore |
centos6
1 | service manticore start |
或者以指定配置wpindex.conf启动
1 | searchd --config /etc/manticoresearch/wpindex.conf |
注意监听的端口！测试下manticore是否工作正常
以默认配置停止Manticore Search服务
1 | service manticore stop |
停止wpindex.conf配置的搜索服务
1 | searchd --config /etc/manticoresearch/wpindex.conf --stop |
添加Manticore Search自启动
1 | chkconfig --level 345 manticore on |
四、添加wp的索引和搜索配置
针对WordPress需要索引的字段编写wpindex.conf配置文件，这个有点儿多，暂时不写，有需要的可以留言，我再写，我也是参照已经定居新西兰的一个程序猿的教程搞的
建立必要的目录
1 | mkdir /var/lib/manticore/data |
1 | cd /var/lib/manticore |
1 | chmod 777 data |
要建立索引
前提是searchd服务器已经启动并监听了9312和9306端口（即第三节中已经按指定wpindex.conf配置启动Manticore Search服务）
添加针对本次需要索引的WordPress数据库配置文件并启用搜索监听服务
1 | cd /etc/manticoresearch |
1 | vi /etc/manticoresearch/wpindex.conf |
写入以下配置（自行去官网研究）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 | # # INDEX GROUP: # MY BLOG # # SOURCES: # src_my_blog # # INDEXES: # idx_blog # # source src_my_blog { type = mysql sql_host = 127.0.0.1 sql_user = root sql_pass = 这里输入你的mysql的root用户密码 sql_db = 这里是你需要建立索引的数据库 sql_query_pre = SET NAMES utf8 sql_query = \ SELECT DISTINCT \ wp_posts.ID as ID, \ wp_posts.post_title as title, \ wp_posts.post_content as body, \ wp_posts.guid as urlid, \ UNIX_TIMESTAMP(wp_posts.post_date) AS date_added \ FROM \ wp_posts \ WHERE \ wp_posts.post_type = 'post' AND \ wp_posts.post_status = 'publish'; sql_field_string = title sql_field_string = body sql_field_string = urlid sql_attr_timestamp = date_added } index idx_blog { type = plain source = src_my_blog path = /var/lib/manticore/data/idx_blog min_word_len = 1 ### support Chinese words query ### charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F ngram_len = 1 ngram_chars = U+3000..U+2FA1F html_strip = 1 html_index_attrs = img=alt,title; a=title; html_remove_elements = style, script, object, embed, span } ############################################################################# ## indexer settings ############################################################################# indexer { # memory limit, in bytes, kiloytes (16384K) or megabytes (256M) # optional, default is 128M, max is 2047M, recommended is 256M to 1024M mem_limit = 256M } ############################################################################# ## searchd settings ############################################################################# searchd { listen = 127.0.0.1:9312 listen = 127.0.0.1:9306:mysql41 log = /var/log/manticore/searchd.log query_log = /var/log/manticore/query.log pid_file = /var/run/manticore/searchd.pid read_timeout = 5 client_timeout = 300 max_children = 30 persistent_connections_limit = 30 seamless_rotate = 1 preopen_indexes = 1 unlink_old = 1 max_packet_size = 8M max_filters = 256 max_filter_values = 4096 max_batch_queries = 32 workers = threads # for RT to work binlog_path = /var/lib/manticore/data # binlog.001 etc will be created there } # --eof-- |
手动建立索引
1 | indexer --config /etc/manticoresearch/wpindex.conf --all --rotate |
测试搜索及索引是否正常，ssh root登录状态进入mysql控制台
1 | mysql -h0 -P9306 |
六、新建crontab任务，每天凌晨4点定时更新索引
在你指定的文件夹内新建一个manticore.sh文件，写入以下命令（参考上面的控制常用命令文章）
/codefiles/crontab是我存放定时任务的shell脚本目录，根据你自己的来
1 | cd /codefiles/crontab |
1 | vi manticore.sh |
在manticore.sh内写入以下命令
1 2 3 | #!/bin/bash searchd --config /etc/manticoresearch/wpindex.conf --stop && indexer --config /etc/manticoresearch/wpindex.conf --all --rotate && searchd --config /etc/manticoresearch/wpindex.conf exit 1 |
添加执行权限
1 | chmod +x manticore.sh |
1 | crontab -e |
vi编辑状态下（按i键），添加以下任务（每天凌晨4点执行索引更新）
1 | 0 4 * * * /codefiles/crontab/manticore.sh |
七、Manticore Search与WordPress结合，使用ajax来展现搜索结果
进入WordPress主题根目录
新建js文件manticore_search.js
写入以下内容：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | function displaysort() { var q=document.getElementById("manticoresearch").value; if (q==""){ return; } var x = document.getElementById("sort"); if (x.style.display === "none") { x.style.display = "block"; } var sort= document.getElementById("sortoption").value; search(sort); } function search(str) { if (str=="") { return; } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (this.readyState==4 && this.status==200) { document.getElementById("searchresult").innerHTML=this.responseText; } } var q=document.getElementById("manticoresearch").value; // xmlhttp.open("GET","//你网站域名/wp-content/themes/你主题文件夹名称/manticore_search.php?q="+q+"&sort="+str,true); xmlhttp.send(); } |
然后在主题根目录新建一个manticore_search.php文件
写入以下内容
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | <?php $q = $_GET['q']; $sort = $_GET['sort']; $manticore = new mysqli("127.0.0.1", "", "", "", 9306); $q=$manticore->real_escape_string($q); if ($sort=="1") { $sphinxQl="SELECT * ,SNIPPET(title,'".$q."','limit=100') as snippet FROM idx_blog WHERE MATCH('".$q."') OPTION max_matches=100"; } else { $sphinxQl="SELECT * ,SNIPPET(title,'".$q."','limit=100') as snippet FROM idx_blog WHERE MATCH('".$q."') ORDER BY date_added DESC"; } $result = $manticore->query($sphinxQl); echo "高级搜索结果:"; echo "<ul class='search-page'>"; foreach($result as $row) { echo "<li class='entry-title'><a href=".str_ireplace('?p=','',($row['urlid'])).".html".">".highlight_word($row['title'],$q).PHP_EOL."</a></li>"; } echo "</ul>"; function highlight_word( $content, $word) { mb_internal_encoding("UTF-8"); mb_regex_encoding("UTF-8"); $replace = '<span style="background-color: #FF0;">' . $word . '</span>'; // create replacement $content = str_ireplace( $word, $replace, $content ); // replace content return $content; // return highlighted data } ?> |
注意：上面的$replace后面的代码可能需要根据你的重写规则进行小调整
然后修改主题的search.php文件，在合适的地方加入以下代码（html内容及样式根据自己主题修改）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <!--manticore search start--> <script type="text/javascript" src="//你网站域名/wp-content/themes/你主题文件夹名称/manticore_search.js"></script> <p><input id="manticoresearch" name="search" type="text" /> <button type="button" onclick="displaysort()">高级搜索</button></p> <div id="sort" style="display:inline-block"> <form> <select name="users" id="sortoption" onchange="search(this.value)"> <option value="1">排序:</option> <option value="1">按相关性</option> <option value="2">按发布时间</option> </select> </form> </div> <div id="searchresult"></div> <!--manticore search end--> |
