使用ssh alan@192.168.122.23 能连接上，但是ssh alan@192.168.122.23 :22无反应，求解决

3

建议还是用 TiUP 来部署吧

4

是用的tiup启动
tiup cluster deploy tidb-test 6.1.0 /Users/alan/.tiup/topology.yaml --user alan

5

他默认ssh给我加上了：22 但是mac的ssh连接又不需要加上端口，不知道怎么办

6

ssh 连接默认端口就是22 后面加端口应该解析成主机名， 不加端口呢

7

不加端口没问题，但是他默认给我加上了就报错了

检查一下权限
.ssh 目录必须是 744，authorized_keys 文件必须是 600

9

建议用脚本互信
./sshUserSetup.sh -user tidb
-hosts “192.168.80.111 192.168.0.114 192.168.80.117 192.168.80.118 192.168.80.119” -advanced \ exverify -confirm

脚本如下
sshUserSetup.sh (32.6 KB)
一路提示yes，yes
什么都不提示就回车
