云原生与微服务：Apache Http Server 2.4 简单配置

查看 Apache Http Server 版本号：apachectl -v。

本文打包后的程序为例，包含前后端（后端只是代理一下），使用 Apache Http Server 2.4 版本。如果是刚安装完的 Apache，默认没有开启 proxy 模块，需要手动开启：

1 2	# 开启所有Proxy模块功能 a2enmod proxy*

然后可以直接 copy 模板 /etc/apache2/sites-available/000-default.conf：

1
2
3

cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/example.com.conf

vim /etc/apache2/sites-available/example.com.conf

添加以下内容，注意 port 要修改为自己前端程序使用的端口。

/etc/apache2/sites-available/example.com.conf

<VirtualHost *:port>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerAdmin webmaster@localhost
    # 前端打包的程序路径
    DocumentRoot /var/lib/projects/workspace/deploy/dist

    # 后端地址代理
    # 正向代理
    ProxyPass /prod-api http://localhost:8081
    # 反向代理
    ProxyPassReverse /prod-api http://localhost:8081

    FallbackResource /index.html

    # 前端打包的程序路径
    <Directory /var/lib/projects/workspace/deploy/dist>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>
    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

然后启用新的配置：

# 启用新的配置
a2ensite example.com.conf

# 查看已启用的配置
ll /etc/apache2/sites-enabled/

Apache 的默认监听端口只有 80，如果其它的端口，我们还需要添加一下：

/etc/apache2/ports.conf

# 添加自己需要的端口
Listen port

Listen 80

<IfModule ssl_module>
        Listen 443
</IfModule>

<IfModule mod_gnutls.c>
        Listen 443
</IfModule>

最后重启服务：

1	systemctl restart apache2
