[Centos7] HTTPS/SSL憑證的SELINUX設置 @新精讚

要讓網頁支援SSL，先決條件，你得申請或購買SSL的憑證，取回的憑證會有以下檔案。

放置憑證檔

/etc/pki/tls/certs/

root.cer, server.cer, server-chain.cer(不一定有中繼憑證)

/etc/pki/tls/private/

privatekey.key

安裝 mod_ssl

檢查 mod_ssl

rpm -qa | grep mod_ssl

如果沒有顯示任何東囑，請安裝

dnf install mod_ssl

編輯 ssl.conf

# vi /etc/httpd/conf.d/ssl.conf

SSLCertificateFile /etc/pki/tls/certs/server.cer
SSLCertificateKeyFile /etc/pki/tls/private/privatekey.key
SSLCACertificateFile /etc/pki/tls/certs/root.cer

# 中繼視情況加上，無則省略
SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt

完整ssl.conf 範列

Listen 443 https
<VirtualHost _default_:443>
    SSLEngine on
    DocumentRoot /home/ddns/public_html
    ServerName ddnss.tc.edu.tw
    <Directory "/home/ddns/public_html">
        Options -Indexes
        AllowOverride All
        Require all granted
    </Directory>
SSLCertificateFile /etc/pki/tls/certs/your_certificate.crt
SSLCertificateKeyFile /etc/pki/tls/private/your_private.key
SSLCACertificateFile /etc/pki/tls/certs/your_ca_certificate.crt
# SSLCertificateChainFile /etc/pki/tls/certs/your_cert_chain.crt
</VirtualHost>

SELINUX 設置

上面的所有憑證檔案，你都得給他們 cert_t 的type

# chcon -u system_u -t cert_t *.cer

# chcon -u system_u -t cert_t privatekey.key

如果沒設置SELINUX，重啟APACHE後，會出現這樣的錯誤，竟然系統說找不到檔案？？

11月 20 00:55:40 example.com httpd[21960]: AH00526: Syntax error on line 102 of /etc/httpd/conf.d/ssl.conf:
11月 20 00:55:40 example.com httpd[21960]: SSLCertificateFile: file '/etc/pki/tls/certs/server.cer' does not exist or is empty

防火牆

# firewall-cmd --zone=public --add-port=443/tcp --permanent

HTTP指定到HTTPS

這個放在你原本的80埠設定裡

<VirtualHost *:80>
...
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

重啟 APACHE
