执行vi topology.yaml，出现下面内容

user: “tidb”
# group is used to specify the group name the user belong to if it’s not the same as user.
group: “tidb”
# systemd_mode is used to select whether to use sudo permissions. When its value is set to user, there is no need to add global.user to sudoers. The default value is system.

# The percentage specifies how much CPU time the unit shall get at maximum, relative to the total CPU time available on one CPU. Use values > 100% for allotting CPU time on more than one CPU.

上面内容和官网安装说明里面的内容不一样，这个要怎么修改，下面是官网安装说明的内容
global:
user: “tidb”
ssh_port: 22
deploy_dir: “/tidb-deploy”
data_dir: “/tidb-data”
server_configs: {}
pd_servers:
- host: 10.0.1.4
- host: 10.0.1.5
- host: 10.0.1.6
tidb_servers: - host: 10.0.1.7
- host: 10.0.1.8
- host: 10.0.1.9
tikv_servers: - host: 10.0.1.1
- host: 10.0.1.2
- host: 10.0.1.3
monitoring_servers: - host: 10.0.1.4
grafana_servers: - host: 10.0.1.4
alertmanager_servers: - host: 10.0.1.4
pd,tidb,tikv这些你都配一个host就可以其他的删掉或者注释掉
好的，我先试试，谢谢
注释掉就是使用默认的

谢谢，兄弟
好的，感谢兄弟
好的，我再尝试看能不能安装成功，感谢兄弟
单机用–user root -p装，会简单不少，不用先创建tidb用户，会自动添加

如何本地备份呢
tiup单机安装很简单呀。官方手册有写。
看官方手册就可以
一个节点跑起来很吃力感觉
