本机模拟集群安装

# 安装tiup
curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh

# tipu生效
source ${your_shell_profile}

# 安装集群
tiup cluster

# 必要时升级集群
tiup update --self && tiup update cluster

# 修改ssh
- 修改 /etc/ssh/sshd_config 将 MaxSessions 调至 20
- systemctl restart sshd

配置文件topo.yaml
