【准備】
1、CentOS 7.6操作系統
2、ext4分區
3、vertica-9.3.1-4.x86_64.RHEL6
4、yum源
三台機器:
10.1.125.39
10.1.125.40
10.1.125.41
【安裝過程】
1、安裝依賴包
[root@localhost ~]# yum install pstack mcelog sysstat dialog ntp -y
2、關閉防火牆
[root@localhost ~]# systemctl mask firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# systemctl stop firewalld
3、設置SELINUX
[root@localhost ~]# vi /etc/selinux/config
SELINUX=disabled
[root@localhost ~]# setenforce 0
4、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 ~]#
5、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
6、確認pts
[root@localhost ~]# ls /dev |grep pts
pts
7、確認磁盤分區
[root@localhost ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 4.4T 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 1G 0 part /boot
├─sda3 8:3 0 4.3T 0 part /home
├─sda4 8:4 0 50G 0 part /
└─sda5 8:5 0 4G 0 part [SWAP]
8、確認磁盤類型，數據庫准備安裝到/home目錄下，所以，"/home"必須是ext4
[root@localhost ~]# cat /etc/fstab
#
# /etc/fstab
# Created by anaconda on Mon Apr 27 17:58:59 2020
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
UUID=f81a61fc-25a9-4250-8692-a72644302c15 / ext4 defaults 1 1
UUID=f20047a1-d7da-4b8a-8592-f2f8cafc229d /boot ext4 defaults 1 2
UUID=7154fd9c-3be8-4788-8c21-e892126be7cd /home ext4 defaults 1 2
UUID=b35075b7-5049-47a0-91f8-719116955148 swap swap defaults 0 0
9、修改I/O scheduler
[root@localhost ~]# echo deadline > /sys/block/sda/queue/scheduler
[root@localhost ~]# echo deadline > /dev/sda2
10、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)
11、安裝依賴的一組服務
[root@localhost ~]# yum install gdb mcelog sysstat chrony ntp ntpdate -y
[root@localhost ~]# systemctl start chronyd
[root@localhost ~]# systemctl status chronyd
[root@localhost ~]# systemctl start ntpd.service
[root@localhost ~]# systemctl enable ntpd.service
12、調整參數
[root@localhost ~]# vi /etc/sysctl.conf
vm.swappiness = 1
[root@localhost ~]# echo 1 > /proc/sys/vm/swappiness
13、設置ntd時間服務器
[root@localhost ~]# vi /etc/ntp.conf
server 10.1.125.42 iburst
14、設置ssh免密訪問
在三台主機上分別執行：
[root@localhost ~]# ssh-keygen -t rsa
一切默認，不用輸入密碼，生成兩個文件：
/root/.ssh/id_rsa
/root/.ssh/id_rsa.pub
在第一台主機上生成authorized_keys文件：
[root@localhost ~]# touch /root/.ssh/authorized_keys
[root@localhost ~]# cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
[root@localhost ~]# chmod 700 /root/.ssh/id_rsa
把另外2台的/root/.ssh/id_rsa.pub文件內容合並到第一台的/root/.ssh/authorized_keys中。
最后，把第一台的/root/.ssh/authorized_keys拷貝到另外兩台主機。
[root@localhost ~]# scp /root/.ssh/authorized_keys root@10.1.125.40:/root/.ssh/
[root@localhost ~]# scp /root/.ssh/authorized_keys root@10.1.125.41:/root/.ssh/
15、設置時區
修改文件/etc/profile增加如下內容：
export LANG="en_US.UTF-8"
export TZ="Asia/Shanghai"
16、修改磁盤預讀參數
修改文件/etc/profile增加如下內容：
[root@localhost ~]# echo '/sbin/blockdev --setra 2048 /dev/sda3' >> /etc/rc.local
[root@localhost ~]# /sbin/blockdev --setra 2048 /dev/sda3
17、重啟操作系統
[root@localhost ~]# reboot
18、解壓縮vertica 9.3
[root@localhost ~]# rpm -ivh vertica-9.3.1-4.x86_64.RHEL6.rpm
[root@localhost ~]# ls /opt/vertica/
19、安裝vertica
[root@localhost ~]# /opt/vertica/sbin/install_vertica --hosts 10.1.125.39,10.1.125.40,10.1.125.41 --rpm vertica-9.3.1-4.x86_64.RHEL6.rpm --failure-threshold FAIL --point-to-point
如果提示有WARN或FATAL，按照提示解決。
如果可以正常安裝，會提示輸入一個數據庫密碼。
20、初始化數據庫
[root@localhost ~]# su - dbadmin
[dbadmin@localhost ~]$ cd /opt/vertica/bin/
[dbadmin@localhost bin]$ ./admintools
1、提示輸入License File Path時，因為用的是社區版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，直接選擇默認的那個IP
8、確認數據實例安裝目錄，不用改，直接用默認的，/home/dbadmin
9、會出現一個k-safe的提示，這是只有一個節點導致的，直接忽略，繼續下一步
10、安裝成功
*** Creating database: bigdata ***

21、測試連接
[dbadmin@localhost bin]$ vsql -h 127.0.0.1 -d bigdata -U dbadmin
User name: dbadmin
Password: ******
Welcome to vsql, the Vertica Analytic Database interactive terminal.
Type: \h or \? for help with vsql commands
\g or terminate with semicolon to execute query
\q to quit
bigdata=>
測試成功！
22、查詢和設置k-safe參數
bigdata=> SELECT current_fault_tolerance FROM system;
尋找當ksafe等於1時候相關的節點
bigdata=> SELECT * FROM v_monitor.critical_nodes;
設置不同ksafe值對節點的要求
K-level Number of Nodes Required
1 3+
2 5+
K 2K+1
一般k最大為2
通常情況下設置ksafe值為1，如下：
bigdata=> SELECT MARK_DESIGN_KSAFE(1);
如果要帶上密碼，可以用“-w”，如下：
vsql -h 127.0.0.1 -d bigdata -U dbadmin -w XXXXXX

社區版vertica默認只允許處理1TB的原始數據(raw data)。
可以通過“select get_compliance_status();”命令來查看當前的使用情況：
