TokuDB引擎安裝起來貌似有點麻煩，在這里做個筆記，安裝幾步走

Percona MySQL5.6安裝

TokuDB引擎安裝

第一步咱們直接省略，跟官方版本MySQL5.6安裝方法基本相同，下面來寫下安裝TokuDB引擎安裝。

一、關閉內存大頁

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

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

查看下

root@ptest:~# cat /sys/kernel/mm/transparent_hugepage/enabled

always madvise [never]

root@ptest:~# cat /sys/kernel/mm/transparent_hugepage/defrag

always madvise [never]

二、安裝jemalloc

上傳jemalloc安裝包jemalloc-4.2.1.tar，這里聽銳志兄說3.6版本以上會出問題，但我這里貌似沒有問題。

上傳后直接解壓編譯安裝就可以了。

導入：

export LD_PRELOAD=/usr/local/jemalloc/lib/libjemalloc.so

查看是否導入成功：

#lsof -n | grep jemalloc

更改MySQL配置文件：(參考老葉的配置文件)

#

#my.cnf

#

# Percona-5.6.17, TokuDB-7.1.6，用于Zabbix數據庫參考配置

# 我的服務器配置：E5-2620 * 2，64G內存，1T可用磁盤空間(建議datadir所在分區設置為xfs文件系統)

# TokuDB版本：Percona-5.6.17, TokuDB-7.1.6(插件加載模式)

重啟MySQL

三、安裝TokuDB引擎

ps_tokudb_admin --enable -uroot -p -S /tmp/mysql3306.sock

輸出如下：

[root@localhost bin]# ps_tokudb_admin --enable -uroot -p -S /tmp/mysql3306.sock

Enter password:

Checking SELinux status...

INFO: SELinux is in permissive mode.

cat: mysql.pid: No such file or directory

Checking if Percona Server is running with jemalloc enabled...

WARNING: The file /proc//environ is not readable so impossible to check LD_PRELOAD for jemalloc.

Possibly running inside container so assuming jemalloc is preloaded and continuing...

If there will be an error during plugin installation try to restart mysql service and run this script again.

Checking transparent huge pages status on the system...

INFO: Transparent huge pages are currently disabled on the system.

Checking if thp-setting=never option is already set in config file...

INFO: Option thp-setting=never is set in the config file.

Checking TokuDB engine plugin status...

INFO: TokuDB engine plugin is not installed.

Installing TokuDB engine...

INFO: Successfully installed TokuDB engine plugin.

表示TokuDB安裝成功，我們進入MySQL查看：

root@localhost [(none)]>show engines;

10 rows in set (0.00 sec)

至此，TokuDB安裝成功，后續會給大家帶來InnoDB與TokuDB引擎的性能測試對比。
