5.1.3. 配置ssh连接上限
添加如下配置到/etc/ssh/sshd_config MaxSessions 100 MaxStartups 50:30:100

重启centos上 sshd: systemctl restart sshd.service

vim /etc/ssh/sshd_config
5.1.4. tiup操作tidb cluster
tiup cluster deploy chainmaker-tidb v5.1.1 topo.yaml --user root -p # 部署 tidb cluster, 输入密码为服务器登陆密码
tiup cluster list # 查看 tidb cluster
tiup cluster start chainmaker-tidb # 启动 tidb cluster
tiup cluster display chainmaker-tidb # 查看 tidb cluster 状态
tiup cluster stop chainmaker-tidb # 停止 tidb cluster
tiup cluster clean chainmaker-tidb --all --ignore-role prometheus --ignore-role grafana # 清理 tidb cluster数据，并保留监控数据
tiup cluster destroy chainmaker-tidb # 销毁 tidb cluster
