apache2 无效命令“SSLEngine”

Question

当我重新启动 httpd 时，出现以下错误。我错过了什么？

[root@localhost ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: Syntax error on line 22 of /etc/httpd/conf.d/sites.conf:
Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration

我已经使用安装了 mod_ssl yum install mod_ssl openssh

Package 1:mod_ssl-2.2.15-15.el6.centos.x86_64 already installed and latest version
Package openssh-5.3p1-70.el6_2.2.x86_64 already installed and latest version

我的sites.conf 看起来像这样

<VirtualHost *:80>
#    ServerName shop.itmanx.com
    ServerAdmin webmaster@itmanx.com

    DocumentRoot /var/www/html/magento
    <Directory /var/www/html>
        Options -Indexes
        AllowOverride All
    </Directory>

    ErrorLog logs/shop-error.log
    CustomLog logs/shop-access.log
</VirtualHost>

<VirtualHost *:443>
    ServerName secure.itmanx.com
    ServerAdmin webmaster@itmanx.com

    SSLEngine on
    SSLCertificateFile /etc/httpd/ssl/secure.itmanx.com/server.crt
    SSLCertificateKeyFile /etc/httpd/ssl/secure.itmanx.com/server.key
    SSLCertificateChainFile /etc/httpd/ssl/secure.itmanx.com/chain.crt

    DocumentRoot /var/www/html/magento
    <Directory /var/www/html>
        Options -Indexes
        AllowOverride All
    </Directory>

    ErrorLog logs/shop-ssl-error.log
    CustomLog logs/shop-ssl-access.log    
</VirtualHost>

Answer 1

在许多系统（Ubuntu、Suse、Debian 等）上运行以下命令来启用 Apache 的 SSL mod：

sudo a2enmod ssl

a2enmod 手册页

Answer 2

可能您没有加载 ssl 模块。您应该在 apache 配置文件中的某处有一个LoadModule指令。

就像是：

LoadModule ssl_module /usr/lib64/apache2-prefork/mod_ssl.so

通常 apache 配置模板（在任何发行版上）都有一个名为（类似）的文件loadmodule.conf，您应该在其中找到LoadModule在服务器启动时加载到 apache 中的每个模块的指令。

在 CentOS 7 上安装包“mod_ssl”并重新启动 apache 服务器对我有用：

yum install mod_ssl
systemctl restart httpd

Answer 4

httpd24 解决方案：

yum install mod24_ssl
