tokuDB 安装与备份小记
线上的数据增长越来越快，数据量的增长也愈来愈大，尤其是日志类数据，这对于数据迁移、数据备份恢复而言，都是一个非常大的挑战。
于是想到了 13 年开源 tokuDB 存储引擎，来解决我们迫在眉睫的容量问题。
TokuDB 是一个高性能、支持事务处理的 MySQL 和 MariaDB 的存储引擎。TokuDB 的主要特点是高压缩比，高 INSERT 性能，支持大多数在线修改索引、添加字段，特别适合像 Zabbix 这种高 INSERT，少 UPDATE 的应用场景。
由于在 Percona 5.6 之后，tokuDB 无法单独作为一个插件直接在 MySQL 社区版上使用（可以成功安装插件，但使用时会陷入无限重启/(ㄒoㄒ)/~~），因而，本次使用 Percona MySQL 最新版 5.7.18，操作系统是 64 bit CentOS 6.9。
安装
1 依赖安装
yum install libaio-devel numactl -y
2 初始化安装和 MySQL 社区版安装一样
3 关闭 MySQL 服务，添加 tokuDB 插件配置，并启动
[mysqld_safe]
malloc-lib=/usr/lib64/libjemalloc.so.1
plugin-dir = /usr/local/mysql/lib/mysql/plugin/
plugin-load=ha_tokudb.so
注意：5.7 以后版本，为了安全，需要将 libjemalloc 复制到 /usr/lib /usr/lib64 目录下才能正确读取
4 安装 tokuDB
ps_tokudb_admin -S /tmp/mysql.sock --enable -uroot -pxxx
注意：此时可以加上 --enable-backup 热备份插件功能
5 添加 tokuDB 配置项
##tokuDB
#tokudb-data-dir = /data/mysql/mysql3306/tokudbData
#tokudb-log-dir = /data/mysql/mysql3306/tokudbLog
#TokuDB的行模式，建议用 FAST ，如果磁盘空间很紧张，建议用 SMALL
#tokudb_default: 设置默认的压缩行为。在 TokuDB 7.1.0版本，默认使用 zlib 库进行压缩，未来版本可能会改变。
#tokudb_fast: 使用 quicklz 库的压缩模式。
#tokudb_small: 使用 lzma 库的压缩模式。
#tokudb_zlib: 使用 zlib 库的压缩模式，提供了中等级别的压缩比和中等级别的CPU消耗。
#tokudb_quicklz: 使用 quicklz 库的压缩模式， 提供了轻量级的压缩比和较低基本的CPU消耗。
#tokudb_lzma: 使用 lzma 库压缩模式，提供了高压缩比和高CPU消耗。
#tokudb_uncompressed: 不使用压缩模式。
tokudb_row_format = tokudb_fast
tokudb_cache_size = 1G ###建议内存的一半
tokudb_commit_sync = 0
tokudb_directio = 1
tokudb_read_block_size = 128K
tokudb_read_buf_size = 128K
备份
1 使用 mysqldump 备份
使用 Percona 版本的 mysqldump 可以备份 tokuDB 的数据，并且额外提供了一个参数 lock-for-backup 来保证数据一致性。
eg:
mysqldump --single-transaction --lock-for-backup --master-data=2 -S /tmp/mysql.sock -uroot -p -A > xxx-2017-6-28.sql
mysqldump has also been extended with a new option, lock-for-backup (disabled by default). When used together with the --single-transaction option, the option makes mysqldump issue LOCK TABLES FOR BACKUP before starting the dump operation to prevent unsafe statements that would normally result in an inconsistent backup.
When used without the single-transaction option, lock-for-backup is automatically converted to lock-all-tables.
Option lock-for-backup is mutually exclusive with lock-all-tables, i.e. specifying both on the command line will lead to an error.
If the backup locks feature is not supported by the target server, but lock-for-backup is specified on the command line, mysqldump aborts with an error. [Link]
2 使用 tokudb-xtrabackup 备份
基于 Percona Xtrabackup 的兼容 tokuDB 的备份工具
yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bison libtool ncurses-devel libgcrypt-devel libev-devel libcurl-devel vim-common -y
git clone https://github.com/BohuTANG/tokudb-xtrabackup
cd tokudb-xtrabackup
cmake .\
-DBUILD_CONFIG=xtrabackup_release\
-DWITH_BOOST=extra/boost/boost_1_59_0.tar.gz\
-DWITH_MAN_PAGES=OFF\
-DCMAKE_INSTALL_PREFIX=/usr/local/tokudb-xtrabackup
make
make install
注意： gcc 的版本最好要 >= 4.8
eg:
/usr/local/tokudb-xtrabackup/bin/innobackupex --defaults-file=/path/to/my.cnf --user=root --password=xxx --no-timestamp /path/to/backup
/usr/local/tokudb-xtrabackup/bin/innobackupex --apply-log /path/to/backup
/usr/local/tokudb-xtrabackup/bin/innobackupex --defaults-file=/path/to/my.cnf --copy-back /path/to/backup
3 使用 tokudb-backup-plugin 备份
官方提供的一个热备份插件
ps_tokudb_admin --enable-backup -S /tmp/mysql.sock -uroot -pxxx
用此命令安装之后，确认配置文件已添加相应的配置项：
# tokudb
innodb_use_native_aio=off
[mysqld_safe]
preload-hotbackup
thp-setting=never
eg:
mysql> set tokudb_backup_dir='/path/to/backup';
