linux tomcat【9.0.12】使用 ssl证书配置 https 的具体操作【使用域名】

1.前言

根据上一个随笔，已经可以正式在阿里云服务器发布工程了，但是用的协议默认是 http ,端口80

但是 http不安全，容易被拦截抓包，于是出来了个 https

tomcat发布对https 的配置根据版本会有所变化，但是其实变化不大

版本9.x版本的tomcat 强制要求证书别名是tomcat，否则报错

引用官网的解释：

下面的演示是在上一随笔的基础上做的，不清楚 Linux使用公网ip配置tomcat ，请去看完上一随笔【 https://www.cnblogs.com/c2g5201314/p/13058413.html 】

2.操作

（1）进入阿里云后台，下载ssl证书和密钥

地址 https://yundun.console.aliyun.com/?spm=5176.10173289.products-recent.dcas.116e2e77ITJsCC&p=cas#/overview/cn-hangzhou

【需要登录才可以访问】

加载的两个文件

在 tomcat根路径新建一个叫cerf的文件夹，将加载的文件拷贝到里面【我是使用xftp传输的】

后缀 .pfx 的文件就是安全证书，另一个是密钥

（2）我的是tomcat 9.0.12，因此需要修改证书别名，不是9.x版本客户省略这一步

需要找到jdk的安装目录，然后找到keytool 的路径

我的是 /usr/local/java/jdk1.8.0_251/bin/keytool

因为我的安全证书的路径是 /usr/local/tomcat/tomcat2/apache-tomcat-9.0.12/cert/3076974_cen2guo.cn.pfx

因此修改别名的指令

/usr/local/java/jdk1.8.0_251/bin/keytool -changealias -keystore /usr/local/tomcat/tomcat2/apache-tomcat-9.0.12/cert/3076974_cen2guo.cn.pfx -alias alias -destalias tomcat

然后会提示输入密码，即密钥文件里的内，回车即可执行【建议直接复制粘贴，手写容易写错，无明文】

（3）配置server.xml文件

服务节点的的端口可以不变，如果需要使用域名，则直接将写有公网ip 的字符串换成域名字符串即可【就两个地方，多简单，哈哈哈】

好了回归正题，配置安全证书
