centos7--安装海量数据库Vastbase M100
1、系统初始化：关闭防火墙、时间同步、初始化等
[root@vastbase ~]# systemctl stop firewalld.service
[root@vastbase ~]# systemctl disable firewalld.service
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.## 这里使用 setenforce 0 临时生效
[root@vastbase ~]# /usr/sbin/setenforce 0
[root@vastbase ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config####依赖包
[root@vastbase ~]# yum install -y zlib-devel libaio libuuid readline-devel krb5-libs libicu libxslt tcl perl openldap pam openssl-devel libxml2 bzip2
2.参数配置
echo "RemoveIPC=no" >> /etc/systemd/logind.conf echo "RemoveIPC=no" >> /usr/lib/systemd/system/systemd-logind.service [root@vastbase ~]# systemctl daemon-reload
[root@vastbase ~]# systemctl restart systemd-logind###内核参数

net.core.netdev_max_backlog = 10000

net.core.wmem_default = 262144

vm.overcommit_memory = 0
vm.swappiness = 0
net.ipv4.ip_local_port_range = 40000 65535
fs.nr_open = 20480000

EOF3、安装
####用户
useradd -m vastbase
passwd vastbase####创建数据库coredump目录
mkdir -p /home/vastbase/data/vdb_coredump
chmod 770 /home/vastbase/data
chown vastbase:vastbase /home/vastbase/data#####创建数据库数据目录（可自定义）
mkdir -p /home/vastbase/data/vastbase
chmod 700 /home/vastbase/data/vastbase
chown -R vastbase:vastbase /home/vastbase/data/vastbase#####创建数据库软件目录（可自定义）
mkdir -p /home/vastbase/local/vastbase
chown -R vastbase:vastbase /home/vastbase###上传包，包是3个月试用期，刚找官方要的，有想要的留言
mkdir -p /home/vastbase/softcp 数据库安装包 /home/vastbase/softchown -R vastbase:vastbase /home/vastbase/soft###切换用户安装
su vastbase
cd soft
tar -zxvf 数据库安装包cd /home/vastbase/soft/vastbase-installer./vastbase_installer
根据提示一步一步安装就行了
4、数据库启动
source ~/.bashrc
##启动数据库 一般会报错
vb_ctl start##分析报错是因为内存参数设置过大，需要修改配置文件/home/vastbase/data/vastbase/postgresql.conf 中以下几个参数值，具体的值根据内存来，尽量设置小：wal_buffers = 32MB
shared_buffers=512MB
max_connections=100
max_process_memory=6144MB
cstore_buffers = 32MB####查看状态
vb_ctl status###登录
vsql -r -d vastbase
5、创建用户和连接
#连接数据库
vsql -d vastbase -p 5432#创建用户
CREATE USER vastbase_test PASSWORD 'Test@123';#创建数据库
CREATE DATABASE vastbase_test OWNER vastbase_test ENCODING 'UTF-8' template = template0;#授予权限
GRANT ALL PRIVILEGES TO vastbase_test;####使用远程连接工具连接时，会有报错需要开启一个参数
password_force_alter=off
