阿裏雲環境安裝vertica操作

1.緩存：阿裏雲默認沒有緩存swap，要手動生成到相應的目錄下

dd if=/dev/zero of=swapfile bs=1024 count=4038336

mkswap swapfile

swapon swapfile

swapon -s

echo "/data/swapfile swap swap defaults 0 0" >>/etc/fstab

2.各類優化

echo deadline > /sys/block/vdb/queue/scheduler

echo deadline > /sys/block/vda/queue/scheduler

/sbin/blockdev --setra 2048 /dev/vdb1

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

echo no > /sys/kernel/mm/redhat_transparent_hugepage/khugepaged/defrag

以上執行完並全部加入到rc.local

yum install pstack mcelog sysstat ntp

/sbin/service ntpd restart

/sbin/chkconfig ntpd on

4.安裝rpm -ivh vertica-*.rpm

/opt/vertica/sbin/install_vertica --hosts 10.28.145.63,10.28.144.236,10.28.144.239 --rpm vertica-8.0.1-0.x86_64.RHEL6.rpm --dba-user mydbb --dba-user-home /data/mydbb -T
