17. 已启用“透明大页面”，它可能会导致重大的性能问题。版本为“CentOS release 6.3 (Final)”且版本为“2.6.32-279.el6.x86_64”的 Kernel 已将 enabled 设置为“[always] never”，并将 defrag 设置为“[always] never”。请运行“echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag”以禁用此设置，然后将同一命令添加到一个 init 脚本中，如 /etc/rc.local，这样当系统重启时就会设置它。或者，升级到 RHEL 6.4 或更新版本，它们不存在此错误。将会影响到以下主机：

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
echo 'echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag' >> /etc/rc.local

18. sysctl -w vm.swappiness=0
echo "vm.swappiness = 0" >> /etc/sysctl.conf

19. yum instlal mysql-connector-java
