Mysql如何在线安装其它引擎

这篇文章主要介绍Mysql如何在线安装其它引擎，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

mysql 在线安装sphinx存储引擎  

需要在现有mysql中安装sphinx的存储引擎，要保证现有mysql运行的情况下完成。mysql也的确支持存储引擎的在线热插拔，下面介绍安装步骤：

1、查看现有mysql的运行版本

[root@localhost plugin]# mysqladmin  -uroot -proot version  

Warning: Using a password on the command line interface can be insecure.

mysqladmin  Ver 8.42 Distrib 5.6.16, for Linux on x86_64

Copyright (c) 2000, 2014, Oracle and/or its affiliates. All rights reserved.

Oracle is a registered trademark of Oracle Corporation and/or its

affiliates. Other names may be trademarks of their respective

owners.

Server version          5.6.16

Protocol version        10

Connection              Localhost via UNIX socket

UNIX socket             /var/lib/mysql/mysql.sock

Uptime:                 1 day 6 hours 26 min 58 sec

Threads: 1  Questions: 35  Slow queries: 0  Opens: 67  Flush tables: 1  Open tables: 60  Queries per second avg: 0.000

2、下载mysql和sphinx

mysql：wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.16.tar.gz

sphinx：http://sphinxsearch.com/downloads/release/ 进去后下载：

Sphinx 2.1.7-release (r4638; Mar 30, 2014)
	Source tarball (tar.gz)	2.1.7-release	2.3M	Download

注意：mysql源码包的版本一定要与当前运行的mysql版本一致！

解压

# tar -xzvf mysql-5.6.16.tar.gz

# tar -xzvf sphinx-2.1.7-release.tar.gz

3、将sphinx-2.1.7-release下的mysqlse目录复制到mysql目录中

#cp -r sphinx-2.1.7-release/mysqlse/ mysql-5.6.16/storage/sphinx

build

# cd mysql-5.6.16

# sh BUILD/autorun.sh

#./configure （此步可以需要yum一些依赖的软件包，否则会有错误或警告）

# make

注意：这里到make这步即可，不用install

4、将make好的文件复制到当前运行的mysql目录中

[root@localhost sphinx]# pwd

/u/opt/mysql-5.6.16/storage/sphinx

cp ha_sphinx.so /usr/lib64/mysql/plugin/

更改所有者（这边试不改也可以）

# chown mysql.mysql /usr/lib64/mysql/plugin/*

注：我当前运行的mysql目录在/usr/local/mysql

5、登陆mysql加载sphinx引擎模块

mysql> show engines;

+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

9 rows in set (0.01 sec)

mysql> INSTALL PLUGIN sphinx SONAME 'ha_sphinx.so';

ERROR 1126 (HY000): Can't open shared library '/usr/lib64/mysql/plugin/ha_sphinx.so' (errno: 2 /usr/lib64/mysql/plugin/ha_sphinx.so: cannot open shared object file: No such file or directory)

这里ERROR发现第一次是ha_sphinx.so位置拷错了，拷正确后：

mysql> INSTALL PLUGIN sphinx SONAME 'ha_sphinx.so';

Query OK, 0 rows affected (0.05 sec)

mysql> show engines;

+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

安装完成！如果要卸载存储模块使用

mysql> UNINSTALL PLUGIN sphinx;  

安装好后,过了几天:

mysql> show engines;

不知道为什么找不到 SPHINX 引擎

只有重新安装一遍看,于是参考网上的:

mysql> INSTALL PLUGIN sphinx SONAME 'ha_sphinx.so';

在开始安装之前,查检一下mysql.plugin表,里边是不是留有老版本的SPHINXSE没有完全清理掉.
