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

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;

+——————–+———+—————————————————————-+————–+——+————+

+——————–+———+—————————————————————-+————–+——+————+

| InnoDB | DEFAULT | Supports transactions, row-level locking, and foreign keys | YES | YES | YES |

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
ERROR 1062 (23000): Duplicate entry sphinx for key PRIMARY
mysql

mysql
mysql delete from mysql.plugin where name= SPHINX
Query OK, 1 row affected (0.02 sec)

mysql
mysql
mysql select * from mysql.plugin;
Empty set (0.00 sec)

mysql install plugin SPHINX soname ha_sphinx.so
Query OK, 0 rows affected (0.00 sec)

mysql show engines;
+——————–+———+—————————————————————-+————–+——+————+

+——————–+———+—————————————————————-+————–+——+————+

mysql

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.
