如何在 redat 6 上配置和编译 apache 2.4 和 ldap 支持
[英]How do I configure and compile apache 2.4 with ldap support on redat 6
问题描述
系统信息：cat /etc/redhat-release Red Hat Enterprise Linux 服务器版本 6.4（圣地亚哥）
uname -a Linux lb-cam-bca-13 2.6.32-642.15.1.el6.x86_64 #1 SMP Fri Feb 24 14:31:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
httpd -version 服务器版本：Apache/2.4.25 (Unix) 服务器搭建：Jun 27 2017 16:23:25
gcc --版本 gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-17)
我已经在我的 rhel 6 机器上安装了 apache 2.4 的本地版本，目前可以正常运行。
但是我现在希望启用 ldap 支持，因此最初尝试使用以下配置：
./configure --prefix=/lb-cam-bca-13/usr/local/apache --with-included-apr --enable-ldap --enable-authnz-ldap --enable-ssl --enable-so --with-ldap
这似乎配置了ol，但是当我尝试构建时，出现以下错误：

我还注意到有一个 --with-openldap 选项，所以我也尝试了，但这导致了配置错误：

查看 config.log 并搜索错误，我看到：

鉴于我在 ssl 上使用 openladap 进行身份验证 - 谁能告诉我应该如何配置和构建 apache 以包括 ldap 身份验证支持？
有谁知道 --with-ldap 和 --with-openldap 之间的区别是什么？ 在什么条件下应该指定其中一个或另一个？
查看第一种情况下的 make 错误，我最初认为包含的 apr 不是用 ldap 构建的，但搜索源文件看起来像是 ldap 包含在内。 有谁知道默认包含的 apr 是否包括 ldap 支持，还是我需要下载并构建一个单独的版本（包括 ldap 支持）？
查看第二种情况下的配置错误 - 这些是否与使用的 gcc 版本有关？
更新：认为可能包含的 apr 要么不支持 ldap，要么在某种程度上与我的 gcc 版本不兼容，我想我会尝试从头开始构建 apr 和 apr-util 并使用 --with 指令将其包含在 httpd建造。 这似乎构建正常，但在尝试运行 apache 时出现链接错误。
我做了以下：下载并解压apr-1.7.0 下载并解压apr-util-1.6.1
配置 apr-1.7.0 并构建它
$ cd apr/apr-1.7.0
./configure --prefix=/lb-cam-bca-13/usr/local/apache
make
make install
配置 apr-util-1.6.1 并构建它
$ ./configure --with-crypto --with-ldap=ldap --with-openssl --with-mysql --with-apr=../../apr/apr-1.7.0 --enable-so
make
make install
配置和构建 httpd
$ ./configure --prefix=/lb-cam-bca-13/usr/local/apache --with-apr=../apr/apr-1.7.0 --with-apr-util=../aprutil/apr-util-1.6.1 --with-ldap --enable-authnz-ldap --enable-so --enable-ssl --enable-md --enable-log-forensic
make
make install
准备启动 apache
$ apachectl stop

有没有人见过这个问题？ 我进行了一些搜索，但一直无法找到合适的解决方案（尽管我之前已经看到一些人发生过类似的错误）
有谁知道我应该怎么做才能确保完整的 apr-util 包含在构建中？
构建时是否需要使用另一个 --with 指令，或者这是创建 .so 文件的问题？

终于解决了。 我在配置文件中对 LoadModule 行使用了不正确的语法。
我放入的 LoadModule 行：
LoadModule mod_authnz_ldap modules/mod_authnz_ldap.so
应该：
LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
然后它工作。 显然，它正在某个地方的某个表中寻找 mod_authnz_ldap 而没有找到它。
使用正确的名称似乎正在加载（尽管我没有尝试过实际使用它）
我被错误信息引导到花园小路上。
