下载openssl*软件包
yum install -y openssl*
之后cd到/etc/pki/CA/文件夹中创建证书
cd /etc/pki/CA
openssl genrsa -out private/cakey.pem 2048
openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3650
根据题目输入证书信息
在创造申请证书
openssl genrsa -out skills.key 2048
openssl req -new -key skills.key -out skills.csr
根据题目填写申请证书信息
创造一个文件
vim sign.cnf
subjectAltName=DNS:*skills.com,DNS=skills.com
openssl ca -in skills.csr -out skills.crt -days 1825 -extfile sign.cnf
配置http服务
yum install -y httpd* mod_ssl*
vim /etc/httpd/conf/httpd.conf
在最后一行编辑80端口的http
<VirtualHost*:80> 定义http 80 网站 疑问：http每个选项的用意以及用法
DocumentRoot "/var/www/html"
ServerName linux1.skills.com
RewriteEngine On
RewriteRule ^/(.*)$ https://www.skills.com/$1 [R=301] 自动跳转域名www.skills.com
<Directory "/">
Requrie all granted
</Directory>
</VirtualHost>
<VirtualHost *:80> http 80端口ip禁止访问代码
ServerName 10.4.220.101
Redirect 403/
</VirtualHost>
配置https服务
vim /etc/httpd/conf.d/ssl.conf
将开头defualt_改成*
定义目录和域名
然后定义证书和私钥
在最后一行编辑
<VirtualHost *:443> https 443端口ip禁止访问代码
ServerName 10.4.220.101
sslengine on
sslcertificatefile /etc/ssl/skills.crt
sslcertificatekeyfile /etc/ssl/skills.key
redirect 403 /
</VirtualHost>
openssl pkcs12 -export -inkey skills.key -in skills.crt -out skills.pfx
openssl pkcs12 -in skills.pfx -out skills.pem -nodes
openssl rsa -in skills.pem -out apache.key
openssl x509 -in skills.pem -out apahce.crt
将cacert.pem和skills.pfx导入到桌面当中，把cacert.pem的后缀改成cer然后安装证书，安装到受信任根证书
pfx证书导入到浏览器的个人证书里面.
tomcat服务以及nginx服务的http，https，反向代理
{虚拟机3和4安装
yum install -y java-17-openjdk* tomcat*
然后再3和4上编辑在最后一行
vim /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-17
export PATH=JAVA(下划线)Home/bin:PATH
source /etc/profile #资源加载
vim /usr/lib/systemd/system/tomcat.service #3和4虚拟机的tomcat配置文件将tomcat改成root用户
vim /etc/tomcat/server.xml} ; #详细内容去word文档查看
