TigerGraph集群安装

## 1.安装必要软件
# 在每个节点执行
sudo su -yum install -y tar curl cronie iproute util-linux-ng net-tools coreutils openssh-clients openssh-server sshpass## 2.配置ssh免登陆
# 在第一个节点执行
ssh-keygen
# 之后一路回车
cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
# 复制如下内容
cat /root/.ssh/id_rsa.pub## 之后在其他两个节点
# 将上面的内容复制进去，并保存
vi /root/.ssh/authorized_keys# 验证第一个节点是否能ssh登录到集群所有节点

# 在某个ntp节点执行
yum install -y ntp# 修改ntp配置文件
vim /etc/ntp.conf把配置文件下面四行注释掉：
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst然后在下面添加这几行：
server 0.cn.pool.ntp.org iburst
server 1.cn.pool.ntp.org iburst
server 2.cn.pool.ntp.org iburst
server 3.cn.pool.ntp.org iburst# 启动ntp服务，并开机自启动
systemctl start ntpd
systemctl enable ntpd## 4.修改ntp配置文件，将上面的NTP服务器作为客户端同步NTP时间服务器
# 在TigerGraph集群的每个节点执行
yum install -y ntp
vim /etc/ntp.conf# 注释掉其他时间服务器
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst# 配置时间服务器为本地搭建的NTP Server服务器
server elk7001# 配置允许NTP Server时间服务器主动修改本机的时间
restrict elk7001 nomodify notrap noquery# 与NTP server服务器同步一下时间：
ntpdate -u elk7001# 查看ntp同步状态
ntpq -p## 5.确保所有节点的时间之间误差不超过1秒
# 与NTP服务器同步时间，可以使用crontab设置定时任务，定时去同步，以下以每5分钟同步一次为例。
crontab -e
# 在crontab配置文件中添加一行
*/5 * * * * root /usr/sbin/ntpdate elk7001
# 关闭防火墙
systemctl stop firewalld
systemctl disable firewalld## 6.集群安装步骤
# 在第一个节点下载安装包
wget http://dl.tigergraph.com/tigergraph-freetrial-latest.tar.gz
tar xzf tigergraph-freetrial-latest.tar.gz
cd tigergraph-3.1.0-offline/
