Percona Server 5.7.14下安装TokuDB存储引擎

Percona Server 5.7.14下安装TokuDB存储引擎
官方文档https://www.percona.com/doc/percona-server/5.7/tokudb/tokudb_installation.html

认识一下TokuDB相关的文件
file1: _test_t1_key_bc_90_3_1b.tokudb --索引(bc)文件
file2: _test_t1_main_90_2_1b.tokudb --主文件
file3: _test_t1_status_90_1_1b.tokudb --表元数据文件

tokudb.directory --表/索引文件信息
tokudb.environment --TokuDB版本号信息
tokudb.rollback --undo记录
log000000000001.tokulog27 --redo记录
__tokudb_lock_dont_delete_me_* --文件锁，保证同一个datadir只能被一个TokuDB进程使用

TokuDB与InnoDB相比有哪些优势？
高压缩，写入快，支持大多数在线修改索引，添加字段，适合像zabbix这种高写入，少更新的应用场景

禁用transparent_hugepage
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

修改my.cnf配置
#tokudb
malloc-lib= /usr/local/mysql/lib/mysql/libjemalloc.so
plugin-dir = /usr/local/mysql/lib/mysql/plugin
plugin-load=ha_tokudb.so

#把TokuDB datadir以及logdir和MySQL的datadir分开，美观点，也可以不分开，注释掉本行以及下面2行即可
tokudb-data-dir = /data/mysql/tokudbData
tokudb-log-dir = /data/mysql/tokudbLog

#TokuDB的行模式，建议用 FAST 就足够了，如果磁盘空间很紧张，建议用 SMALL
#tokudb_row_format = tokudb_small
tokudb_row_format = tokudb_fast
tokudb_cache_size = 44G

#TokuDB其他大部分配置其实可以不用修改的，只需要几个关键配置即可
tokudb_commit_sync = 0
tokudb_directio = 1
tokudb_read_block_size = 128K
tokudb_read_buf_size = 128K

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

启动MySQL
/etc/init.d/mysqld start
