git克隆代码报错ssh: connect to host gitlab.test.cn port 22: Connection timed out

#gitlab克隆代码报错

ssh: connect to host gitlab.test.cn port 22: Connection timed out

#先telnet服务器22端口是否通畅，端口通畅服务器端22端口没有问题检查本机防火墙和selinux是否打开，端口不通畅请检查服务器带宽(这边报错是由于阿里云的ecs没有配置安全组对22端口的放行报错)

 

telnet 10.0.3.2

 

 

#做git初始化然后在配置用户名和邮箱
#git初始化
git init
#配置用户名和邮箱
git config --global user.name "pengzhenwei"
git config --global user.email "pengzhenwei@wbiao.cn"

#端口通畅可能是秘钥生成方法不对
ssh-keygen -t rsa -C 'xxxxx@xxxx.cn此为gitlab上面填写资料的邮箱'

#再次克隆代码恢复正常
