| tidb60 | 192.168.68.60 | MySQL8.0.20 |
| tidb61 | 192.168.68.61 | MySQL8.0.20 |
| tidb62 | 192.168.68.62 | MySQL8.0.20 |
| tidb63 | 192.168.68.63 | MySQL-shell,MySQL-route |
二、下载安装包sql
https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz
https://cdn.mysql.com//Downloads/MySQL-Router/mysql-router-8.0.20-linux-glibc2.12-x86_64.tar.xz

二、环境部署session
2.1 MySQL8.0.20 实例部署，以tidb60主机上为例。socket
mkdir -p /home/mysql_cluster/my3366/{socket,data,logs,dump_dir}ide
cd /home/mysql_clusteroop
chown -R mysql:mysql my3366测试
/usr/local/mysql8020/bin/mysqld --defaults-file=/home/mysql_cluster/my3366/my3366.cnf --initializeui
nohup /usr/local/mysql8020/bin/mysqld_safe --defaults-file=/home/mysql_cluster/my3366/my3366.cnf --user=mysql &

2.2 配置检查
在tidb63主机上部署mysqlshell，下载后解压，配置环境变量便可使用，部署路径跟进实际环境便可。

2.3 建立集群
能够在任一 一个节点上执行，根据测试发现初次加入集群的这节点最终是是master节点，便可以R/W
