Hi
System info:
$ cat /etc/*-release
| Code: | CentOS Linux release 7.6.1810 (Core)

CentOS Linux release 7.6.1810 (Core) |
$ uname -a
| Code: | | Linux lb-cbga-eq 3.10.0-1062.1.1.el7.x86_64 #1 SMP Fri Sep 13 22:55:44 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux |
---------------------------------------------
I have a centos 6 machine that runs a locally built version of httpd 2.4.25 as a reverse proxy. To do this I have set up virtual hosts and use the ProxyHTMLURLMap directive which seems to work fine.
I am now trying to do a similar thing using the out of the box httpd 2.4.6 on a centos 7 machine. When I try to use a similar configuration I get an error:
| Code: | | Invalid command 'ProxyHTMLURLMap', perhaps misspelled or defined by a module not included in the server configuration |
I think this is because mod_proxy_html.so is required for this - is that correct ?
When I try to load the module using the LoadModule directive I get the following error:
| Code: | | httpd: Syntax error on line 127 of /etc/httpd/conf/httpd.conf: Cannot load modules/mod_proxy_html.so into server: /etc/httpd/modules/mod_proxy_html.so: cannot open shared object file: No such file or directory |
And indeed I cannot see the mod_proxy_html.so in the modules directory.
Does anyone know how I can install a mod_proxy_html.so for an out of the box httpd on centos 7?
Or is the only way to do this to build it from source (as I have done on my centos 6 box) ?
Edit:
I did try to install using the following command:
$ yum install mod_proxy_html
and got the following error:
| Code: | No package mod_proxy_html available.
Error: Nothing to do |

Thank you for the reply.
I downloaded that one, but got the following errors:
| Code: | # rpm -i mod_proxy_html-2.4.6-93.el7.centos.aarch64.rpm
warning: mod_proxy_html-2.4.6-93.el7.centos.aarch64.rpm: Header V3 RSA/SHA256 Signature, key ID 305d49d6: NOKEY
error: Failed dependencies:
httpd = 0:2.4.6-93.el7.centos is needed by mod_proxy_html-1:2.4.6-93.el7.centos.aarch64
httpd-mmn = 20120211aarch64 is needed by mod_proxy_html-1:2.4.6-93.el7.centos.aarch64

ld-linux-aarch64.so.1(GLIBC_2.17)(64bit) is needed by mod_proxy_html-1:2.4.6-93.el7.centos.aarch64 |
However searching specifically for such individual rpm files I found this:
| Code: | | http://lxsoft102.cern.ch/cern/centos/7.6.1810/sclo/x86_64/rh/Packages/h/httpd24-mod_proxy_html-2.4.34-18.el7.x86_64.rpm |
Using rpm to install it does not complain:
| Code: | | rpm -i httpd24-mod_proxy_html-2.4.34-18.el7.x86_64.rpm |
But there is still not any modules/mod_proxy_html.so. Do I need to do something to generate it ? |

I don't have CentOS But you need to load the module like
| Code: | LoadModule proxy_module /usr/lib64/httpd/modules/mod_proxy.so
LoadModule proxy_html_module /usr/lib64/httpd/modules/mod_proxy_html.so
|
is there are in proxy-html.conf /etc/httpd/conf.d/ ? |

The problem is there is no mod_proxy_html.so module in /usr/lib64/httpd/modules:
| Code: | $ ls /usr/lib64/httpd/modules/mod_proxy_html.so
ls: cannot access /usr/lib64/httpd/modules/mod_proxy_html.so: No such file or directory |
> is there are in proxy-html.conf /etc/httpd/conf.d/ ?
No there wasn't
I copied /usr/share/doc/httpd-2.4.6/proxy-html.conf to conf.d and uninstalled and re-installed the rpm. However mod_proxy_html.so still does not exist.
Do I need to edit /proxy-html.conf ? |

That file needs at least
| Code: |
ProxyHTMLLinks a href
ProxyHTMLLinks area href
ProxyHTMLLinks link href
ProxyHTMLLinks img src longdesc usemap
ProxyHTMLLinks object classid codebase data usemap
ProxyHTMLLinks q cite
ProxyHTMLLinks blockquote cite
ProxyHTMLLinks ins cite
ProxyHTMLLinks del cite
ProxyHTMLLinks form action
ProxyHTMLLinks input src usemap
ProxyHTMLLinks head profile
ProxyHTMLLinks base href
ProxyHTMLLinks script src for
# To support scripting events (with ProxyHTMLExtended On),
# you'll need to declare them too.
ProxyHTMLEvents onclick ondblclick onmousedown onmouseup \
onmouseover onmousemove onmouseout onkeypress \
onkeydown onkeyup onfocus onblur onload \
onunload onsubmit onreset onselect onchange

Looks like my proxy-html.conf does include that list.
Whatever I do it seems I am unable to get the standard mod_proxy_html - not even sure what command should get it - when I install the rpm ?
I have got httpd running with mod_proxy_html by building apr/apr-util/httpd from source. Not sure it is possible to do using the delivered httpd. |
