Percona Server 的安装及tokudb引擎的安装笔记
2017年7月7日
安装percona server：
yum localinstall Percona-Server-client-57-5.7.18-15.1.el6.x86_64.rpm Percona-Server-shared-57-5.7.18-15.1.el6.x86_64.rpm Percona-Server-server-57-5.7.18-15.1.el6.x86_64.rpm Percona-Server-tokudb-57-5.7.18-15.1.el6.x86_64.rpm
安装过程中，会自动安装jmelloc组件。

初始化数据库：
/usr/sbin/mysqld --initialize-insecure --basedir=/usr/sbin/ --user=mysql --datadir=/var/lib/mysql/
# 说明：使用 --initialize-insecure参数，不让mysqld初始化时候生成随机密码，保持空密码
启动数据库：
/etc/init.d/mysql start
设置数据库密码：
mysql
> set password=PASSWORD(‘[email protected]‘);
> flush privileges;
> exit
然后，开始安装tokudb引擎：
官方详细的安装步骤： https://www.percona.com/doc/percona-server/5.7/tokudb/tokudb_installation.html
1 禁用Transparent huge pages
cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
always代表已启用
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
# 将设置写入到文件，防止重启配置丢失
echo ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled‘ >> /etc/rc.local
echo ‘echo never > /sys/kernel/mm/transparent_hugepage/defrag‘ >> /etc/rc.local
2、安装并启用tokudb引擎：
## 可以使用INSTALL PLUGIN方法安装，也可以使用ps_tokudb_admin这个工具进行配置（推荐使用ps_tokudb_admin）
执行 ps_tokudb_admin -uroot [email protected] --enable
会自动在 /etc/my.cnf 在加入下面的1行配置
[mysqld_safe]
thp-setting=never
然后再执行 ps_tokudb_admin -uroot [email protected] --enable-backup
会自动在 /etc/my.cnf 在加入下面的1行配置
[mysqld_safe]
preload-hotbackup
这样就完成了TokuDB engine plugin和TokuBackup plugin插件的安装。
重启mysqld进程。
/etc/init.d/mysql restart
mysql -uroot [email protected]
> show engines;
> show plugins;
> SELECT @@tokudb_version;
都可以看到tokudb启用了。
这样的话，我们重启了mysqld或者整个服务器的话，tokudb引擎也能在mysql重启时候再次自动加载。
