Mysql如何安裝tokudb引擎

Mysql如何安裝tokudb引擎，很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。

平臺支持：

    TokuDB 只能在 64-bit Linux 下使用.
最小內(nèi)存要求：
    TokuDB 需要至少1GB 的物理內(nèi)存,當然這里建議最好是 2GB 

安裝tokuDB   

      tokuDB內(nèi)存分配需要jemalloc支持（一般安裝percona mysql以后自己就有，如果沒有則需要額外安裝）    

 1 安裝jemalloc

1.          yum install jemalloc
        編譯安裝參考：http://blog.itpub.net/29096438/viewspace-2122906/

 2：安裝tokudb

1. 二進制包安裝：

2. 下載：

3. [root@host-192-168-1-56 plugin]# wget https://www.percona.com/downloads/Percona-Server-5.6/Percona-Server-5.6.24-72.2/binary/tarball/Percona-Server-5.6.24-rel72.2-TokuDB.Linux.x86_64.ssl101.tar.gz

解壓拷貝tokudb.so至mysql plugin目錄即可
[root@host-192-168-1-56 plugin]# cp ha_tokudb.so /home/data/mysql/lib/plugin/

修改內(nèi)核配置，禁用transparent_hugepage，不關(guān)閉的話可能會導致TokuDB內(nèi)存泄露（建議寫到 /etc/rc.local 中，重啟后仍可生效）：
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

安裝即可

4 配置文件tokudb參數(shù)設(shè)置

1. [mysqld_safe]
   malloc-lib=/usr/local/mysql/lib/libjemalloc.so
   plugin-dir =/usr/local/mysql/lib/mysql/plugin/
   
   

2. #tokudb

3. #把TokuDB datadir以及l(fā)ogdir和MySQL的datadir分開，美觀點，也可以不分開，注釋掉本行以及下面2行即可
   

4. tokudb-data-dir = /data/mysql/zabbix_3306/tokudbData
   

5. tokudb-log-dir = /data/mysql/zabbix_3306/tokudbLog
   

6.  
   

7. #TokuDB的行模式，建議用 FAST 就足夠了，如果磁盤空間很緊張，建議用 SMALL
   

8. #tokudb_row_format = tokudb_small
   

9. tokudb_row_format = tokudb_fast
   

10. tokudb_cache_size = 44G
    

11.  
    

12. #其他大部分配置其實可以不用修改的，只需要幾個關(guān)鍵配置即可
    

13. tokudb_commit_sync = 0
    

14. tokudb_directio = 1
    

15. tokudb_read_block_size = 128K
    

16. tokudb_read_buf_size = 128K

若將上述參數(shù)寫在[mysqld]下，則show engines中tokudb引擎不存在了了，失效了
若將上述參數(shù)寫在[mysqld_safe]下，tokudb引擎還存在，也能建立tokudb表，但是這些參數(shù)配置是沒生效的。。。。。。。待解決

注意：

1. mysql版本：mysql官方社區(qū)版5.6.24 搭建成功后 新建表就重啟，建標就重啟

2. 
   

1. 錯誤日志：遇到了bug？

2. Version: '5.6.24-log'  socket: '/home/data/mydata/3308/mysql.sock'  port: 3308  Source distribution
   08:44:47 UTC - mysqld got signal 11 ;
   This could be because you hit a bug. It is also possible that this binary
   or one of the libraries it was linked against is corrupt, improperly built,
   or misconfigured. This error can also be caused by malfunctioning hardware.
   We will try our best to scrape up some info that will hopefully help
   diagnose the problem, but since we have already crashed, 
   something is definitely wrong and this may fail.
   
   
   key_buffer_size=8388608
   read_buffer_size=131072
   max_used_connections=1
   max_threads=8096
   thread_count=1
   connection_count=1
   It is possible that mysqld could use up to 
   key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3220280 K  bytes of memory
   Hope that's ok; if not, decrease some variables in the equation.

4. 解決辦法：換成percona server 

5. 社區(qū)版5.6.24

6. 得以解決
