大家好，我是「Bigder」~
Linux下使用wget下载tomcat「wget https://dlcdn.apache.org/tomcat/tomcat-8/v8.5.78/bin/apache-tomcat-8.5.78.tar.gz」
出现下面的错误提示，不能下载：
wget https://dlcdn.apache.org/tomcat/tomcat-8/v8.5.78/bin/apache-tomcat-8.5.78.tar.gz --2022-04-06 21:54:57-- https://dlcdn.apache.org/tomcat/tomcat-8/v8.5.78/bin/apache-tomcat-8.5.78.tar.gz Resolving dlcdn.apache.org (dlcdn.apache.org)… 191.101.2.132, 2a04:4e42::644 Connecting to dlcdn.apache.org (dlcdn.apache.org)|191.101.2.132|:443… connected. ERROR: cannot verify dlcdn.apache.org’s certificate, issued by ‘/C=US/O=Let’s Encrypt/CN=R3’: Issued certificate has expired. To connect to dlcdn.apache.org insecurely, use `–no-check-certificate’.
解决方法：
wget带参数：–no-check-certificate
「wget --no-check-certificate https://dlcdn.apache.org/tomcat/tomcat-8/v8.5.78/bin/apache-tomcat-8.5.78.tar.gz」
