Question

我见过here，我应该安装mod_rpaf，以便Apache能够检测来自Nginx反向代理的IP。

即使看到Ununtu SO上存在错误，也应该更改/etc/apache2/mods-available/rpaf.conf上的第一行。

第一行包含<IfModule rpaf_module>。我尝试用<IfModule mod_rpaf-2.0.c>替换，但是当我重新启动Apache时没有任何改变。

这是我尝试安装此模块时的输出：

根据错误，您的系统上已经有一个/usr/lib/apache2/modules/mod_rpaf.so版本，其文件大小与软件包配置的预期不同（预期签名为41503234，但是看到了41503232），所以你需要：

1）找出安装了冲突版本的内容并将其卸载：

dpkg -S /usr/lib/apache2/modules/mod_rpaf.so
apt-get --purge remove <package>

或者如果手动添加：

mv /usr/lib/apache2/modules/mod_rpaf.so /usr/lib/apache2/modules/mod_rpaf.so.bak
apt-get install libapache2-mod-rpaf

这可能会破坏其他东西。

2）手动下载re-compile and install from source，应解决当前问题，但如果您尝试通过apt更新，则会遇到相同的冲突签名问题。

3）Unpack the deb file, hack the hash in the config, repackage and install.
