curl --proto '=https' --tlsv1.2 -sSf | sh % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed100 4410k 100 4410k 0 0 2064k 0 0:00:02 0:00:02 --:--:-- 2063k
2、测试tiup工具
[root@localhost tidb-tiup]# source /root/.bash_profile[root@localhost tidb-tiup]# which tiup/root/.tiup/bin/tiup
3、查看可以下载的tidb版本
[root@deam tidb]# tiup list tidbAvailable versions for tidb:Version Installed Release Platforms------- --------- ------- ---------nightly 2020-07-08T06:39:00+08:00 linux/arm64,darwin/amd64,linux/amd64v3.0 2020-04-16T16:58:06+08:00 darwin/amd64,linux/amd64v3.0.0 2020-04-16T14:03:31+08:00 darwin/amd64,linux/amd64v3.0.1 2020-04-27T19:38:36+08:00 linux/arm64,darwin/amd64,linux/amd64v3.0.2 2020-04-16T23:55:11+08:00 darwin/amd64,linux/amd64v3.0.3 2020-04-17T00:16:31+08:00 darwin/amd64,linux/amd64v3.0.4 2020-04-17T00:22:46+08:00 darwin/amd64,linux/amd64v3.0.5 2020-04-17T00:29:45+08:00 darwin/amd64,linux/amd64v3.0.6 2020-04-17T00:39:33+08:00 darwin/amd64,linux/amd64v3.0.7 2020-04-17T00:46:32+08:00 darwin/amd64,linux/amd64v3.0.8 2020-04-17T00:54:19+08:00 darwin/amd64,linux/amd64v3.0.9 2020-04-17T01:00:58+08:00 darwin/amd64,linux/amd64v3.0.10 2020-03-13T14:11:53.774527401+08:00 darwin/amd64,linux/amd64v3.0.11 2020-04-17T01:09:20+08:00 darwin/amd64,linux/amd64v3.0.12 2020-04-17T01:16:04+08:00 darwin/amd64,linux/amd64v3.0.13 2020-04-26T17:25:01+08:00 darwin/amd64,linux/amd64v3.0.14 2020-05-09T21:11:49+08:00 linux/arm64,darwin/amd64,linux/amd64v3.0.15 2020-06-05T16:50:59+08:00 linux/arm64,darwin/amd64,linux/amd64v3.0.16 2020-07-03T20:05:15+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.0-beta 2020-05-22T14:35:59+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.0-beta.1 2020-05-22T15:22:30+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.0-beta.2 2020-05-22T15:28:20+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.0-rc 2020-05-22T15:56:23+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.0 2020-05-22T15:34:33+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.1 2020-04-30T21:02:32+08:00 linux/arm64,darwin/amd64,linux/amd64v3.1.2 2020-06-04T17:53:39+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-beta 2020-05-26T11:18:05+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-beta.1 2020-05-26T11:42:48+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-beta.2 2020-05-26T11:56:51+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-rc 2020-05-26T14:56:06+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-rc.1 2020-04-29T01:03:31+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0-rc.2 2020-05-15T21:54:51+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.0 2020-05-28T16:23:23+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.1 2020-06-15T12:00:45+08:00 linux/arm64,darwin/amd64,linux/amd64v4.0.2 2020-07-01T19:57:14+08:00 linux/arm64,darwin/amd64,linux/amd64
4、生成需要的tidb离线版本（这儿生成的v4.0.2）
[root@localhost tidb-tiup]# tiup mirror clone tidb-community-server-v4.0.2-linux-amd64 v4.0.2 --os=linux --arch=amd64Start to clone mirror, targetDir is tidb-community-server-v4.0.2-linux-amd64, selectedVersions are [v4.0.2]If this does not meet expectations, please abort this process, read `tiup mirror clone --help` and run againArch [amd64]OS [linux]download 22.54 MiB / 22.54 MiB 100.00% 2.03 MiB p/s download 3.55 MiB / 3.55 MiB 100.00% ? p/s download -
5、打包离线文件
tar czvf tidb-community-server-v4.0.2-linux-amd64.tar.gz tidb-community-server-v4.0.2-linux-amd64
6、内网tidb安装
将离线包发送到目标集群的中控机后，执行以下命令安装 TiUP 组件：
tar xzvf tidb-community-server-v4.0.2-linux-amd64.tar.gz && sh tidb-community-server-v4.0.2-linux-amd64/local_install.shsource /home/tidb/.bash_profile
7、TiKV 数据盘挂载
磁盘大于1T方法#fdisk -lDisk /dev/vdb: 1000 GB#parted -s -a optimal /dev/vdb mklabel gpt -- mkpart primary ext4 1 -1 #创建分区#mkfs.ext4 /dev/vdb1 #格式化磁盘#echo "UUID=`lsblk -f|grep vdb1|awk '{print $3}'` /data1 ext4 defaults,nodelalloc,noatime 0 2" >> /etc/fstab #配置开机自动挂载#more /etc/fstab#mkdir /data1 && mount -a #挂载盘----------------------------磁盘小于1T方法pvcreate /dev/vdbvgcreate vg_data /dev/vdblvcreate -l 100%VG -n lv_tidb vg_data mkdir /data1mkfs.ext4 /dev/mapper/vg_data-lv_tidbecho "UUID=`lsblk -f|grep vg_data-lv_tidb|awk '{print $3}'` /data1 ext4 defaults,nodelalloc,noatime 0 2" >> /etc/fstab more /etc/fstabmount -a8、配置ssh免密登陆
ssh-keygen #一直回车ssh-copy-id root@10.0.0.1 #输入密码配置免密登陆ssh-copy-id root@10.0.0.2ssh-copy-id root@10.0.0.3ssh-copy-id root@10.0.0.4ssh-copy-id root@10.0.0.5ssh-copy-id root@10.0.0.6ssh-copy-id root@10.0.0.7
9、集群初始化配置文件需要手动编写，需要在中控机上面创建 YAML 格式配置文件，例如 topology.yaml:
# # Global variables are applied to all deployments and used as the default value of# # the deployments if a specific deployment value is missing.global: user: "tidb" ssh_port: 22 deploy_dir: "/tidb-deploy" data_dir: "/tidb-data"server_configs: pd: replication.enable-placement-rules: truepd_servers: - host: 10.0.1.4 - host: 10.0.1.5 - host: 10.0.1.6tidb_servers: - host: 10.0.1.7 - host: 10.0.1.8 - host: 10.0.1.9tikv_servers: - host: 10.0.1.1 - host: 10.0.1.2 - host: 10.0.1.3tiflash_servers: - host: 10.0.1.10 data_dir: /data1/tiflash/data,/data2/tiflash/datacdc_servers: - host: 10.0.1.6 - host: 10.0.1.7 - host: 10.0.1.8monitoring_servers: - host: 10.0.1.4grafana_servers: - host: 10.0.1.4alertmanager_servers: - host: 10.0.1.4
以前版本没有缓存服务器的配置
pd_servers: - host: 172.16.5.134 name: pd-134 - host: 172.16.5.139 name: pd-139 - host: 172.16.5.140 name: pd-140tidb_servers: - host: 172.16.5.134 - host: 172.16.5.139 - host: 172.16.5.140tikv_servers: - host: 172.16.5.134 - host: 172.16.5.139 - host: 172.16.5.140grafana_servers: - host: 172.16.5.134monitoring_servers: - host: 172.16.5.134
10、部署 TiDB 集群
useradd tidb #每台服务器创建tidb用户echo 'yourpasswd'|passwd --stdin tidbexport TIUP_MIRRORS=/path/to/mirror #/path/to/mirror 是执行 local_install.sh 命令时输出的离线镜像包的位置tiup cluster deploy tidb-cluster v4.0.2 topology.yaml --user tidb tiup cluster start tidb-cluster
11、tidb常用命令
[root@localhost tidb-tiup]# tiup clusterThe component `cluster` is not installed; downloading from repository.download 9.62 MiB / 9.62 MiB 100.00% 245.11 MiB p/s Starting component `cluster`: /root/.tiup/components/cluster/v1.0.7/tiup-clusterDeploy a TiDB cluster for productionUsage: tiup cluster cluster [flags] tiup cluster [command]Available Commands: check Perform preflight checks for the cluster. deploy Deploy a cluster for production start Start a TiDB cluster stop Stop a TiDB cluster restart Restart a TiDB cluster scale-in Scale in a TiDB cluster scale-out Scale out a TiDB cluster destroy upgrade Upgrade a specified TiDB cluster exec Run shell command on host in the tidb cluster display Display information of a TiDB cluster list List all clusters audit Show audit log of cluster operation import Import an exist TiDB cluster from TiDB-Ansible edit-config Edit TiDB cluster config reload Reload a TiDB cluster's config and restart if needed patch Replace the remote package with a specified package and restart the service help Help about any commandFlags: -h, --help help for tiup --ssh-timeout int Timeout in seconds to connect host via SSH, ignored for operations that don't need an SSH connection. (default 5) -v, --version version for tiup --wait-timeout int Timeout in seconds to wait for an operation to complete, ignored for operations that don't fit. (default 60) -y, --yes Skip all confirmations and assumes 'yes'Use "tiup cluster help [command]" for more information about a command.
三、在线部署安装
1、所有节点需配置ssh免密登录
ssh-keygen #一直回车ssh-copy-id root@10.0.0.1 #输入密码配置免密登陆ssh-copy-id root@10.0.0.2ssh-copy-id root@10.0.0.3ssh-copy-id root@10.0.0.4ssh-copy-id root@10.0.0.5ssh-copy-id root@10.0.0.6ssh-copy-id root@10.0.0.7
2、关闭SElinux、关闭防火墙
# 关闭防火墙systemctl stop firewalldsystemctl disable firewalld# 关闭selinuxsed -i 's/enforcing/disabled/' /etc/selinux/config # 永久setenforce 0 # 临时
3、安装tiup工具
curl --proto '=https' --tlsv1.2 -sSf | sh
4、安装完成后重新声明环境变量
source .bash_profile
5、确认安装位置
which tiup
6、安装 TiUP cluster 组件
tiup cluster
7、创建 topology.yaml 文件
global: user: "bbders" ssh_port: 51668 deploy_dir: "/ssd/tidb-deploy" data_dir: "/ssd/tidb-data"monitored: node_exporter_port: 9100 blackbox_exporter_port: 9115 deploy_dir: "/ssd/tidb-deploy/monitored-9100" data_dir: "/ssd/tidb-data/monitored-9100" log_dir: "/ssd/tidb-deploy/monitored-9100/log"server_configs: pd: replication.enable-placement-rules: truepd_servers: - host: 10.28.100.151 - host: 10.28.100.160 - host: 10.28.100.161tidb_servers: - host: 10.28.100.151 - host: 10.28.100.160 - host: 10.28.100.161tikv_servers: - host: 10.28.100.151 - host: 10.28.100.160 - host: 10.28.100.161monitoring_servers: - host: 10.28.100.161grafana_servers: - host: 10.28.100.161alertmanager_servers: - host: 10.28.100.161
8、TiDB基本操作命令
查看已部署的集群$ tiup cluster list启动集群$ tiup cluster start bbders-tidb查看集群状态$ tiup cluster display bbders-tidb
9、访问地址
dashboard访问地址：默认用户/密码：root/空Grafana访问地址：默认用户/密码：admin/admin
四、扩容主机
1、查看当前配置
tiup cluster list #查看当前的集群名称列表tiup cluster edit-config <cluster-name> #查看集群配置、拷贝对应的配置
2、编写扩容脚本，复制上一步看到的配置信息即可
vi scale-out.yamltikv_servers:- host: 192.168.112.60 ssh_port: 22 port: 20160 status_port: 20180 deploy_dir: /ssd/tidb-deploy/tikv-20160 data_dir: /ssd/tidb-data/tikv-20160 arch: amd64 os: linux- host: 192.168.112.61 ssh_port: 22 port: 20160 status_port: 20180 deploy_dir: /ssd/tidb-deploy/tikv-20160 data_dir: /ssd/tidb-data/tikv-20160 arch: amd64 os: linux- host: 192.168.112.62 ssh_port: 22 port: 20160 status_port: 20180 deploy_dir: /ssd/tidb-deploy/tikv-20160 data_dir: /ssd/tidb-data/tikv-20160 arch: amd64 os: linux
3、执行扩容脚本
tiup cluster scale-out <cluster-name> scale-out.yaml
4、检查集群状态
tiup cluster display <cluster-name>
5、重启grafana
tiup cluster restart <cluster-name> -R grafana
五、缩容主机节点
1、 查看集群信息
tiup cluster display <cluster-name> 查看集群信息
2、执行缩容操作
tiup cluster scale-in <cluster-name> --node 10.0.1.5:20160
