1.前言

根據上一個隨筆，已經可以正式在阿里雲服務器發布工程了，但是用的協議默認是 http ,端口80

但是 http不安全，容易被攔截抓包，於是出來了個 https

tomcat發布對https 的配置根據版本會有所變化，但是其實變化不大

版本9.x版本的tomcat 強制要求證書別名是tomcat，否則報錯

引用官網的解釋：

下面的演示是在上一隨筆的基礎上做的，不清楚 Linux使用公網ip配置tomcat ，請去看完上一隨筆【 https://www.cnblogs.com/c2g5201314/p/13058413.html 】

2.操作

（1）進入阿里雲后台，下載ssl證書和密鑰

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

【需要登錄才可以訪問】

加載的兩個文件

在 tomcat根路徑新建一個叫cerf的文件夾，將加載的文件拷貝到里面【我是使用xftp傳輸的】

后綴 .pfx 的文件就是安全證書，另一個是密鑰

（2）我的是tomcat 9.0.12，因此需要修改證書別名，不是9.x版本客戶省略這一步

需要找到jdk的安裝目錄，然后找到keytool 的路徑

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

因為我的安全證書的路徑是 /usr/local/tomcat/tomcat2/apache-tomcat-9.0.12/cert/3076974_cen2guo.cn.pfx

因此修改別名的指令

/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

然后會提示輸入密碼，即密鑰文件里的內，回車即可執行【建議直接復制粘貼，手寫容易寫錯，無明文】

（3）配置server.xml文件

服務節點的的端口可以不變，如果需要使用域名，則直接將寫有公網ip 的字符串換成域名字符串即可【就兩個地方，多簡單，哈哈哈】

好了回歸正題，配置安全證書
