ubuntu16.04 taos分布式集群部署

安装环境

网络规划

系统初始化

1.时区设置

#设置时区为上海
timedatectl set-timezone Asia/Shanghai
#查看是否修改成功
timedatectl status

2.时间同步

#修改NTP服务器为阿里云
sed -ri '/^#NTP/s/(.*)(=.*)/NTP=ntp.aliyun.com/' /etc/systemd/timesyncd.conf
sed -ri '/^#FallbackNTP/s/(.*)(=.*)/FallbackNTP=ntp1.aliyun.com/' /etc/systemd/timesyncd.conf
#重启时间同步服务
systemctl restart systemd-timesyncd.service

3.hosts文件同步（h1上执行）

#添加/etc/hosts
vim /etc/hosts
172.16.199.125    h1 h1.taosdata.com
172.16.199.148    h2 h2.taosdata.com
172.16.199.229    h3 h3.taosdata.com
scp /etc/hosts h2:/etc/
scp /etc/hosts h3:/etc/

4.安装TDengine

#安装软件（3个节点都执行）
#安装时提升数据FQDN，输入：h1.taosdata.com:6030
dpkg -i TDengine-server-2.0.19.1-Linux-x64.deb
#h1修改配置文件,确保fqdn正确
vim /etc/taos/taos.cfg
fqdn                      h1.taosdata.com
#h2修改配置文件,确保fqdn正确
vim /etc/taos/taos.cfg
fqdn                      h2.taosdata.com
#h3修改配置文件,确保fqdn正确
vim /etc/taos/taos.cfg
fqdn                      h2.taosdata.com
#挂载数据盘到/var/lib/taos（3个节点都执行）
vim /etc/fstab
/dev/sdb    /var/lib/taos    exe4    default    0    2
mount -a
#启动服务（3个节点都执行）
systemctl start taosd.service

5.集群设置

#查看当前的dnodes
taos
taos> show dnodes;
   id   |           end_point            | vnodes | cores  |   status   | role  |       create_time       |      offline reason      |
======================================================================================================================================
      1 | h1.taosdata.com:6030           |      0|     16 | ready      | any   | 2021-12-31 17:06:45.689 |                          |
Query OK, 1 row(s) in set (0.003205s)
#创建h2与h3 dnode
taos> create dnode "h2.taosdata.com:6030";
taos> create dnode "h3.taosdata.com:6030";
#再次查看当前的dnodes
taos> show dnodes;
   id   |           end_point            | vnodes | cores  |   status   | role  |       create_time       |      offline reason      |

#查看mnodes
taos> show mnodes;
   id   |           end_point            |     role     |       create_time       |
