cd /etc/httpd/conf/ssl.key
mv server.key server.key.orig
openssl genrsa 2048 > server.key
cd /etc/httpd/conf/
mkdir ssl.csr
openssl req -new -key ssl.key/server.key -out ssl.csr/server.csr

回答一堆問題之後，可能要考慮密碼不打

記得要有 ssl.crt 這個目錄

openssl x509 -req -days 1825 -in ssl.csr/server.csr -signkey ssl.key/server.key -out ssl.crt/server.crt

到 /etc/pki/tls/certs
修改一下 Makefile 把 365 改成大一點的數字，每年搞一次我可沒力氣。
我改成 1825 五年差不多了。

然後 make xxxx.pem 填一填資料就可以了，最後記得要把
ipop3d.pem
與 imapd.pem 連到 xxxx.pem 即可。

    記得，憑證不可以被別人隨便讀取，正確的說應該是憑證的private key
不能被讀取，所以要設定適當的權限。 閱讀全文 mail憑證的製作法 Fedora 7 →
