【準備】
1、CentOS 7.6的映象盤（下載地址：官網）
2、vertica-9.1.0-0.x86_64.RHEL6（下載地址：https://pan.baidu.com/s/1IjWBUTku_zMpccF2VQ9iDw 密碼：qd7p）
3、外網環境
【安裝過程】
1、安裝CentOS 7.6
minimal installation模式即可
注意！根目錄“/”掛載的檔案系統必須是ext4，不能是預設的xfs！
2、配置網路，能夠訪問外網
3、安裝依賴包
[root@localhost ~]# yum install pstack mcelog sysstat dialog ntp -y
4、關閉防火牆
[root@localhost ~]# systemctl mask firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# systemctl stop firewalld
5、設定SELINUX
[root@localhost ~]# vi /etc/selinux/config
SELINUX=disabled
[root@localhost ~]# setenforce 0
6、確認Python版本，要求2.7版本以上
[root@localhost ~]# which python
/usr/bin/python
[root@localhost ~]# python --version
Python 2.7.5
[root@localhost ~]#
7、安裝rsync，要求3.0.5版本以上
[root@localhost ~]# yum install rsync -y
[root@localhost ~]# rsync --version
rsync version 3.1.2 protocol version 31
8、確認pts
[root@localhost ~]# ls /dev |grep pts
pts
9、確認磁碟分割槽
[root@localhost ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 40G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 39G 0 part
├─centos-root 253:0 0 37G 0 lvm /
└─centos-swap 253:1 0 2G 0 lvm [SWAP]
sr0 11:0 1 1024M 0 rom
10、確認磁碟型別，"/dev/mapper/centos-root /"必須是ext4
[root@localhost ~]# cat /etc/fstab
/dev/mapper/centos-root / ext4 defaults 1 1
UUID=d91f7088-7e3d-4995-8c01-22ab932ef85a /boot xfs defaults 0 0
/dev/mapper/centos-swap swap swap defaults 0 0
11、修改I/O scheduler
[root@localhost ~]# echo deadline > /sys/block/sda/queue/scheduler
[root@localhost ~]# echo deadline > /dev/sda2
12、安裝JDK1.8
[root@localhost ~]# yum install java-1.8.0-openjdk.x86_64 -y
[root@localhost ~]# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
13、安裝依賴的一組服務
[root@localhost ~]# yum install gdb mcelog sysstat chrony ntp ntpdate -y
[root@localhost ~]# systemctl status chronyd
[root@localhost ~]# systemctl start ntpd.service
[root@localhost ~]# systemctl enable ntpd.service
14、調整引數
[root@localhost ~]# vi /etc/sysctl.conf
vm.swappiness = 1
[root@localhost ~]# echo 1 > /proc/sys/vm/swappiness
15、解壓縮vertica 9.1
[root@localhost ~]# rpm -ivh vertica-9.1.0-0.x86_64.RHEL6.rpm
[root@localhost ~]# ls /opt/vertica/
16、安裝vertica（192.168.248.128是本機IP）
[root@localhost ~]# /opt/vertica/sbin/install_vertica --host 192.168.248.128 --rpm vertica-9.1.0-0.x86_64.RHEL6.rpm --failure-threshold FAIL --point-to-point
如果提示有WARN或FATAL，按照提示解決。
例如：
HINT (S0305): https://my.vertica.com/docs/9.1.x/HTML/index.htm#cshid=S0305
TZ is unset for dbadmin. Consider updating .profile or .bashrc
解決：sh -c "echo 'export TZ=Asia/Shanghai' >> /home/dbadmin/.bash_profile"
如果可以正常安裝，會提示輸入一個資料庫密碼。
17、初始化資料庫
[root@localhost ~]# su - dbadmin
[dbadmin@localhost ~]$ cd /opt/vertica/bin/
[dbadmin@localhost bin]$ ./admintools
1、提示輸入License File Path時，因為用的是社群版license，不用填，直接回車，
2、Accept EULA
3、Configuration Menu
4、Create Database
5、輸入Database Name: bigdata
6、輸入密碼和確認密碼
7、選擇主機IP，因為是單節點安裝，直接選擇預設的那個IP
8、確認資料例項安裝目錄，不用改，直接用預設的，/home/dbadmin
9、會出現一個k-safe的提示，這是隻有一個節點導致的，直接忽略，繼續下一步
10、安裝成功

vsql: warning: extra command-line argument "dbadmin" ignored
vsql: Warning: The -u option is deprecated. Use -U.

測試成功！
--------------------------
社群版vertica預設只允許處理1TB的原始資料(raw data)。
可以通過“select get_compliance_status();”命令來檢視當前的使用情況，例如：
當資料庫處理的原始資料過多時，可以通過刪除舊資料來釋放一些空間。刪除後，使用“select get_compliance_status();”命令檢視並不能馬上看到有變化，這時，需要使用資料庫【管理員】賬號先執行“select audit_license_size();”命令進行重新統計，然後就可以看到最新的使用情況了。
如果資料超過了license授權的1TB限制，會報錯並影響正常使用。
