1. Percona介绍
Percona Server由领先的MySQL咨询公司Percona发布。 Percona Server是一款独立的数据库产品，其可以完全与MySQL兼容，可以在不更改代码的情况了下将存储引擎更换成XtraDB 。
Percona团队的最终声明是“Percona Server是由Oracle发布的最接近官方MySQL Enterprise发行版的版本”，因此与其他更改了大量基本核心MySQL代码的分支有所区别。 Percona Server的一个缺点是他们自己管理代码，不接受外部开发人员的贡献，以这种方式确保他们对产品中所包含功能的控制。 Percona提供了高性能XtraDB引擎，还提供PXC高可用解决方案，并且附带了perconatoolkit等DBA管理工具箱
Zabbix 3.0 for percona-server TokuDB
安装perconna源
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
安装依赖
yum install epel-release -y yum install jemalloc -y ++++++++++++++++++++++++++++++++++++++ TokuDB storage engine requires libjemalloc library 3.3.0 or greater.
If the version in the distribution repository is lower than that you can use one from Percona Software Repositories or download it from somewhere else. If the libjemalloc wasn’t installed and enabled before it will be automatically installed when installing the TokuDB
storage engine package by using the apt` or yum package manager, but Percona Server instance should be restarted for libjemalloc to be loaded.
This way libjemalloc will be loaded with LD_PRELOAD.
You can also enable libjemalloc by specifying malloc-lib variable in the [mysqld_safe] section of the my.cnf file: [mysqld_safe] malloc-lib= /path/to/jemalloc +++++++++++++++++++++++++++++++++++++++
关闭大页内存
echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag ? +++++++++++++++++++++++++++++++++++ TokuDB won’t be able to start if the transparent huge pages are enabled.
Transparent huge pages is feature available in the newer kernel versions. You can check if the Transparent huge pages are enabled with: $ cat /sys/kernel/mm/transparent_hugepage/enabled [always] madvise never If transparent huge pages are enabled and you try to start the TokuDB engine you’ll get the following message in you error.log: Transparent huge pages are enabled, according to /sys/kernel/mm/redhat_transparent_hugepage/enabled Transparent huge pages are enabled, according to /sys/kernel/mm/transparent_hugepage/enabled You can disable transparent huge pages permanently by passing transparent_hugepage=never to the kernel in your bootloader
(NOTE: For this change to take an effect you’ll need to reboot your server). You can disable the transparent huge pages by running the following command as root (NOTE: Setting this will last only until the server is rebooted): echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag ++++++++++++++++++++++++++++++++++++++++
安装percona数据库及tokudb插件
yum install Percona-Server-tokudb-57.x86_64
启动mysql
systemctl start mysqld
登录并更改密码和过期策略
登录：
mysql -u root -p ,c!)fa/Cd9kD 更改密码及过期策略： SET PASSWORD = PASSWORD(‘Qwe_1234‘); ALTER USER ‘root‘@‘localhost‘ PASSWORD EXPIRE NEVER; flush privileges;
配置root用户远程登录（只是为了测试，不代表生产操作）
grant all privileges on *.* to root@"%" identified by "Qwe_1234";
测试本地登录与远程登录(我数据库IP为10.0.0.12)
mysql -uroot -pQwe_1234 mysql -uroot -pQwe_1234 -h 10.0.0.12 -P3306
