使用 TiUP cluster 在单机上模拟生产环境部署步骤

本文链接：https://blog.youkuaiyun.com/wade1010/article/details/128651180

该文描述了如何配置和部署TiDB集群，包括通过curl下载安装脚本，设置root用户的sshd_config以增加MaxSessions，然后使用tiup工具进行集群配置，如tidb、tikv和pd服务器的详细配置，并提供了具体的IP和端口设置。

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

source /root/.bash_profile

tiup cluster

vim /etc/ssh/sshd_config

由于模拟多机部署，需要通过 root 用户调大 sshd 服务的连接数限制：

修改 /etc/ssh/sshd_config 将 MaxSessions 调至 20。

重启 sshd 服务：

service sshd restart

cd /opt && mkdir tidb-cluster && cd tidb-cluster

如果vim粘贴时格式有问题就 :set paste 再粘贴

tiup cluster deploy ./topo.yaml --user root -p

tiup cluster deploy tidb-cluster v5.0.1 ./topo.yaml --user root -p

tiup cluster start tidb-cluster
