安装mysql,centos 环境wget出现Unable to establish SSL connection.

[root@VM-0-15-centos ~]#  wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

问题分析

wget后跟的url为https，对应端口443，https为加密传输的协议

加上参数 --no-check-certificate 一起使用，即==>wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz --no-check-certificat --no-check-certificat 在不检查安全证书，以不安全的方式连接指定url的作用
