确保 libjemalloc 高于 3.3.0
[root@fund-mgmt-db-mog-2 ~]# yum list |grep jemalloc
jemalloc.x86_643.6.0-1.el7 @percona-release-x86_64
jemalloc-debuginfo.x86_64 3.3.1-1.el7 percona-release-x86_64
jemalloc-devel.x86_64 3.6.0-1.el7 percona-release-x86_64

一定要大页支持，才能启动 tokudb
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

安装tokudb包
yum -y UNINSTALL Percona-Server-tokudb-57.x86_64

让 tokudb 引擎生效
ps_tokudb_admin --enable -uroot -p###### -S /home/mysql/my3313/run/mysql.sock -P 3313
