本文介紹下如何在ubuntu系統中，利用apt工具，搭建mysql+sphinx的全文檢索環境。

一 安裝mysql

1 更新源列表

開啟"終端視窗"，輸入"sudo apt-get update"-->回車-->"輸入root使用者的密碼"-->回車,就可以了。如果不執行該命令，直接安裝mysql,會出現"有幾個軟體包無法下載，您可以執行apt-get update------"的錯誤提示，導致無法安裝。

2 安裝mysql

開啟"終端視窗"，輸入"sudo apt-get install mysql-server mysql-client"-->回車-->輸入"y"-->回車-->在"軟體包設定對話方塊"中輸入mysql中"root"使用者的密碼-->回車-->再輸一次密碼-->回車,安裝完成。

3 如何判斷mysql是否安裝成功

開啟"終端視窗"，輸入"sudo service mysql restart"-->回車-->如果mysql啟動成功，處於執行狀態說明mysql安裝成功。

4 讓apache支援mysql

開啟"終端視窗"，輸入"sudo apt-get install libapache2-mod-auth-mysql"-->回車-->安裝成功，安裝這個模組後，apache才能支援mysql。

5 讓php支援mysql

開啟"終端視窗"，輸入"sudo apt-get install php5-mysql"-->回車-->安裝成功，安裝這個模組後，php才能支援mysql。

6 登入mysql

開啟"終端視窗"，輸入"mysql -u root -p"-->回車-->輸入mysql中"root"使用者的密碼-->回車-->登入成功。

二安裝sphinx

       01、安裝全文搜尋引擎 Sphinx 前，必須先安裝 MySQL server 並設定資料庫 root 使用者(參考步驟一)

       02、使用 apt-get 方法直接安裝 Sphinx:

1. apt-get install sphinxsearch

1. cp /etc/sphinxsearch/sphinx.conf.sample /etc/sphinxsearch/sphinx.conf
   
2. vi /etc/sphinxsearch/sphinx.conf

1. sql_user = test
   
2. sql_pass =
   
3. # compat_sphinxql_magics = 1

1. sql_user = root
   
2. sql_pass = 您的資料庫 root 使用者密碼
   
3. compat_sphinxql_magics = 0

1. vi /etc/default/sphinxsearch

1. START=no

1. START=yes

1. root:~# mysql -u root -p
   
2. Enter password: 鍵入您的資料庫 root 使用者密碼
   
3. Welcome to the MySQL monitor.  Commands end with ; or \g.
   
4. Your MySQL connection id is 20177
   
5. Server version: 5.5.40-0ubuntu0.14.04.1 (Ubuntu)

10. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
    
11. mysql>create database test;
    
12. Query OK, 1 row affected (0.00 sec)
    
13. mysql> use test;
    
14. Reading table information for completion of table and column names
    
15. You can turn off this feature to get a quicker startup with -A
    
16. Database changed
    
17. mysql> exit
    
18. Bye
    
19. root:~#
    

1. /etc/sphinxsearch/example.sql

mysql -u root -p你的root密碼 -Dtest < /etc/sphinxsearch/example.sql

1. indexer --all

1. root:~# service sphinxsearch start
