关闭 THP
THP（Transparent Huge Pages） 在有数据库服务（Mysql、Redis、MongoDB）的机器上都是建议关闭的 不然总会发生莫名其妙的事情，TokuDB 也是一定要关闭的。

在 /etc/rc.local 加入如下语句，这样就算重启系统也会自动关闭 THP

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

# systemctl start mysqld
默认密码在：grep password /var/log/mysqld.log
首次登录需呀修改一次
set global validate_password_policy=0;
ALTER USER 'root'@'%' IDENTIFIED BY 'dev@mysql';
flush privileges;

mongo

yum install numactl -y
rpm -ivh Percona-Server-MongoDB-34-*
# 创建用户
/usr/bin/percona-server-mongodb-enable-auth.sh

redis

yum install -y wget make gcc tcl && make distclean && make && make install
