TiDB入门篇-集群的扩容缩容
简介
测试集群的扩容缩容和备份恢复。
参考
使用 TiUP 扩容缩容 TiDB 集群 | PingCAP 文档中心
操作（用tidb的时候出现了错误下面使用root启动集群）
缩容pd以及缩容以后的影响
#如果是tidb的话，在pd扩容会失败root就不会，所以建议启动tidb的时候使用root启动
global:
# # The user who runs the tidb cluster.
user: "root"选做
#销毁集群
tiup cluster destroy tidb-deploy
#重新创建集群检查
tiup cluster check ./topology.yaml --apply --user root -p
#部署集群
tiup cluster deploy tidb-deploy v6.5.1 ./topology.yaml --user root -p
1.查看下开始的集群状态。
tiup cluster display tidb-deploy如下都是up状态

#查看下缩容以后的结果
tiup cluster display tidb-deploy如下pd变成了2个

尝试下2个pd是否还能够继续使用。
mysql --comments --host 127.0.0.1 --port 4000 -u root -p
use test;
create table test1(name varchar(10));
insert into test1 values('1');
insert into test1 values('1');
insert into test1 values('1');
select * from test1;
mysql> select * from test1;
+------+

3 rows in set (0.00 sec)
可以看到只有2个pd还是可能正常工作，下面在缩容一个pd。

结论：
pd节点的个数主要是保证的高可用，在部署3个节点以后，缩容到2个或者一个都还能够继续工作，唯一不同的就是dashboard在对应的pd缩容以后地址也进行了变化。
扩容PD
1.编写扩容配置文件。
vi scale-out.yaml
pd_servers:
- host: 192.168.66.10
ssh_port: 22
name: pd-1
client_port: 2377
peer_port: 2381
deploy_dir: /data/nihao/deploy/pd-2379
data_dir: /data/nihao/data/pd-2379
log_dir: /data/nihao/log/pd-23792.执行下面的命令。
#执行 scale-out 命令前，先使用 check 及 check --apply 命令，检查和自动修复集群存在的潜在风险：
tiup cluster check tidb-deploy scale-out.yaml --cluster --user root -p
#执行检查时会提示需要优化
192.168.66.10 thp Fail THP is enabled, please disable it for best performance
#自动修改存在的风险
tiup cluster check tidb-deploy scale-out.yaml --cluster --apply --user root -p
tiup cluster scale-out tidb-deploy scale-out.yaml -p
tiup cluster display tidb-deploy[root@master ~]# tiup cluster display tidb-deploy
