一台物理机从VMWare ESXi到taos集群搭建的全过程
使用公司小机房一台IBMx3650m3服务器(16核逻辑CPU/8G内存/500G硬盘)安装VMWare ESXi系统,再通过VMWare新建三台CentOS7虚拟机来实现taos集群的搭建。一、使用U盘安装VMWare ESXi 6.5系统镜像下载地址(百度云):链接: https://pan.baidu.com/s/10foa29-cYcU7d3RzCLR4rg 提取码: sy45 复制这段内

1、制作U盘启动
首先进入UltraISO软件;
点击菜单【文件】-----打开.....
选择你的ISO路径,选定打开;
点击菜单【启动光盘】----写入硬盘映像
打开ISO后选择启动光盘,然后再选择写入硬盘映像;
选择硬盘驱动器(就是你的U盘盘符);
点击【格式化】,格式化一下U盘
格式化完成后,选择【写入方式】,可选择:
USB-HDD/USB-ZIP/USB-HDD+/USB-ZIP+ (小编选的是HDD+,接着点击写入);
当程序提示刻录成功!的信息,就表示制作成功了(小编不由得长嘘了一口气)。
2、使用U盘启动服务器进行系统安装
给服务器上电后按F1进入BOSS设置
进入BOSS设置后查看Start Options里面有没有USB启动选项,如果没有就进入Boot Manager中进行添加,添加成功后保存重启就可以进入安装了。
具体安装过程可以参考这篇博客:https://blog.csdn.net/zll_0405/article/details/79172239
二、新建CentOS 7虚拟机
1、网页登录esxi系统:192.168.1.194
2、 点击导航起中的虚拟机,在右侧选择创建/注册虚拟机,然后创建新的虚拟机
3、填写虚拟机名称、操作系统系列、操作系统版本,然后下一页
4、选择存储,下一页
5、在自定义设置中设置CPU、内存等
6、然后点击完成就新建好了
三、给虚拟机安装系统
1、上传操作系统到服务器磁盘
依次点击存储、数据存储浏览器、上载,打开文件选择框,选择需要安装的centOS系统上传到服务器。
centOS下载地址:http://mirrors.aliyun.com/centos/7/isos/x86_64
2、给刚刚新建的虚拟机挂在CD/ROM软盘,镜像选择上传的centos7系统
3、打开虚拟机电源进行系统安装
安装过程中尽量配置静态IP,防止动态IP可能会发生改变。
四、给虚拟机安装Vmware tools

1、将下载下来的tools解压上传到服务器硬盘上,可以参考将操作系统上传到服务器硬盘上的方式
2、将虚拟机的CD/ROM镜像修改为tools中的linux.iso
3、使用SSH登录虚拟机操作系统进行操作

安装完成后刷新虚拟机页面就可以看到
如果出现错误:./vmware-install.pl: /user/bin/perl: 坏的解释器:没有那个文件或目录
解决方法
yum install perl gcc kernel-devel
yum upgrade kernel kernel-devel
如果出现
Searching for a valid kernel header path…
The path “” is not valid.
这是因为 kernel-devel版本和相应的kernel版本不一致,可以用uname-r看一下内核版本,再用rpm -q kernel-devel看一下kernel-devel的版本,有可能会出现kernel-devel未找到的错误,这里需要自己安装一下,可以执行 sudo yum install kernel-devel,这个时候会安装最新的kernel-devel版本,重启一下,如果再出现问题,那么可以执行sudo yum upgrade kernel kernel-devel,把内核和kernel-devel更新到同一个版本,这样应该就不会有问题了。而GCC和PERL的问题提示比较简单。
建议在安装之前还是执行一下安装GCC和PERL,执行发下命令:yum install perl gcc kernel-devel。
五、配置虚拟机
1、配置静态IP
首先注意,路由网关处必须设置可以配置静态IP或者使用指定IP绑定MAC才可以配置,否则配置不成功,不要盲目的配置
网络配置的配置文件在/etc/sysconfig/network-scripts/下,文件名前缀为ifcfg-后面跟的就是网卡的名称,可以通过双TAB键查看然后编辑,也可以使用ifconfig查看,也可以使用命令: ls /etc/sysconfig/network-scripts/ifcfg-* 列出所有的设备配置文件,
比如这里就是ifcfg-eno16777984这个文件,ifcfg-lo是本地回环地址的配置文件,所有计算机都有,不用动他,
现在使用: vim /etc/sysconfig/network-scripts/ifcfg-eno16777984 打开配置文件进行编辑,默认情况是dhcp动态获取的,如下图:
这时候如果想修改成静态的,首先把BOOTPROTO="dhcp"改成BOOTPROTO="static"表示静态获取,然后在最后追加比如下面的配置:
BROADCAST=192.168.1.255 IPADDR=192.168.1.33 NETMASK=255.255.255.0 GATEWAY=192.168.1.1
BROADCAST设置的是局域网广播地址,IPADDR就是静态IP,NETMASK是子网掩码,GATEWAY就是网关或者路由地址;需要说明,原来还有个NETWORK配置的是局域网网络号,这个是ifcalc自动计算的,所以这里配置这些就足够了,最终配置如下图:
配置完成之后保存退出,
设置完毕,然后使用命令: /etc/init.d/network restart 或者 service network restart 重启网络服务,重启后如果路由配置了支持静态IP,那么linux就能获取到刚才配置的IP地址,这样静态IP就配置成功了
配置成功后,dns配置一般会消失,所以这时候就ping不通域名了,需要配置DNS,配置文件位置是:/etc/resolv.conf,里面的nameserver指定dns服务器地址,这个配置很简单就不详细说了,如下图:
保存后,dns配置是立即生效的,原因很简单,只要本地需要解析缓冲区没有的域名,都要读取一遍dns配置文件,所以这个配置是立即生效的,不用任何操作
到这里静态IP并访问外网就没问题了
2、安装ifconfig命令
yum search ifconfig
安装搜索出来的net-tools包即可:yum -y install net-tools...
3、安装lrzsz命令
yum install -y lrzsz
4、安装JDK
4.1上传安装包,并解压
4.2配置环境变量
vim /etc/profile
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_221
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
source /etc/profile
安装成功
六、搭建taos集群
1、配置hosts
2、安装taos服务端
解压:tar xf TDengine-server-2.0.20.10-Linux-x64.tar
安装:cd TDengine-server-2.0.20.10/ ./install.sh
给三台服务器做相互免密登陆。
scp taos文件夹到其他的两台服务器进行安装。
修改TDengine的配置文件(所有节点的文件/etc/taos/taos.cfg都需要修改)。假设准备启动的第一个数据节点End Point为 h1.taosdata.com:6030, 其与集群配置相关参数如下:
// firstEp 是每个数据节点首次启动后连接的第一个数据节点
firstEp h1.taosdata.com:6030
// 必须配置为本数据节点的FQDN,如果本机只有一个hostname, 可注释掉本配置
fqdn h1.taosdata.com
// 配置本数据节点的端口号,缺省是6030
serverPort 6030
// 使用场景,请参考《Arbitrator的使用》的部分
arbitrator ha.taosdata.com:6042
一定要修改的参数是firstEp和fqdn。在每个数据节点,firstEp需全部配置成一样,但fqdn一定要配置成其所在数据节点的值。其他参数可不做任何修改,除非你很清楚为什么要修改。
官方安装文档:https://www.taosdata.com/cn/documentation/cluster#prepare
导出虚拟机 原文链接:https://blog.csdn.net/qq_35428201/article/details/81435144
修改hostname、IP地址、UUID
vim /etc/hostname
vim /etc/sysconfig/network-scripts/ifcfg-ens192
添加防火墙开发端口:
firewall-cmd --zone=public --add-port=6030-6042/tcp --permanent
firewall-cmd --zone=public --add-port=6030-6042/udp --permanent
添加完成后需要重新加载才能生效:
firewall-cmd --reload
查看是否生效:
firewall-cmd --zone=public --list-ports
虚拟机在线扩容磁盘:
1、扩展磁盘
注意:扩容磁盘的方式分为 [添加磁盘]、[扩展磁盘] ; 扩展磁盘需要在此虚拟机停止的状态下进行,同时扩展的数字是扩展后的预期大小,比如之前是60G,希望扩展200G,那么我们应该输入200G。这里我们以扩展磁盘的方式进行。go go go !
2、首先确认状态
扩展后,重新启动linux,使用df -kh命令发现磁盘目录大小没有变化
使用fdisk确认磁盘空间是否已经扩展
可以看到“Disk /dev/sda: 53.7 GB”,已经扩展了34G空间。
3、扩展分区
[admin@localhost ~]$ sudo fdisk /dev/sda
Welcome to fdisk (util-linux 2.23.2).Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Syncing disks.
4、加载分区表
方法一:(推荐)
[root@taos1 ~]# partprobe
执行 partprobe命令用于将磁盘分区表变化信息通知内核,并请求操作系统重新加载分区表,此方法可以不用重启系统;
方法二:reboot
5、分区确认
通过fdisk可以看到已经添加了/dev/sda3
6、扩展vg
创建PV
[root@taos1 ~]# pvcreate /dev/sda3
Physical volume "/dev/sda3" successfully created.
使用vgs查看
[root@taos1 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
centos 1 2 0 wz--n- <15.00g 0
7、把sda3加入到LVM组中
[root@taos1 ~]# vgextend centos /dev/sda3 Volume group "centos" successfully extended
注意:centos 是vg组名称,请根据具体情况填写
[root@taos1 ~]# vgs VG #PV #LV #SN Attr VSize VFree centos 2 2 0 wz--n- 48.99g <34.00g
8、扩展lv
我们把新扩展的34G全部添加到centos-root中
[root@taos1 ~]# lvextend /dev/mapper/centos-root /dev/sda3
Size of logical volume centos/root changed from 13.39 GiB (3429 extents) to 47.39 GiB (12132 extents).
Logical volume centos/root successfully resized.
使用lvs可以看到 centos-root 已经是140G了,但是…请继续往下看
使用df -kh查看,空间并没有变化,look down…
9、xfs在线扩容
[root@taos1 ~]# xfs_growfs /dev/mapper/centos-root
meta-data=/dev/mapper/centos-root isize=512 agcount=4, agsize=877824 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0 spinodes=0
data = bsize=4096 blocks=3511296, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
data blocks changed from 3511296 to 12423168
10、再次确认df状态, 添加的100G空间已经有效
