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。

/etc/my.cnf 内容如下：

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。
