# |
|
# chkapachessl() determines whether a server's Apache SSL configuration |
|
# needs updating to support LON-CAPA. |
|
# |
|
# LON-CAPA uses VirtualHosts for port 443, and requires that they are |
|
# defined in one Apache configuration file containing two VirtualHost |
|
# blocks, in order: |
|
# |
|
# (1) a block with no ServerName, or with ServerName set to the |
|
# server's hostname. This block should contain: |
|
# |
|
# <IfModule mod_rewrite.c> |
|
# LON-CAPA rewrite rules defined in sslrewrite.conf |
|
# </IfModule> |
|
# |
|
# (2) a block with ServerName set to internal-$hostname |
|
# (where $hostname is server's hostname). |
|
# This block should contain the config and rewrite rules |
|
# found in loncapassl.conf. |
|
# |
|
# chkapachessl() retrieves the names of .conf files in |
|
# the directory appropriate for the particular Linux distro, |
|
# and then checks to see which .conf file is the best candidate as |
|
# the single file containing VirtualHosts definitions and |
|
# <IfModule mod_rewrite.c> </IfModule> rewrite blocks. |
|
# |
|
# The best candidate is the one containing a block: |
|
# <VirtualHost ????? :443> |
|
# (where ????? might be _default_ or * or an IP address) |
|
# <IfModule mod_rewrite.c> |
|
# </IfModule> |
|
# </VirtualHost> |
|
# with the fewest differences between the contents of the |
|
# IfModule block and the expected contents (from sslrewrite.conf) |
|
# |
|
# If there are no files with rewrite blocks, then a candidate file |
|
# is chosen from the .conf files containing VirtualHosts definitions. |
|
# |
|
# If the user includes "Configure SSL for Apache web server" as |
|
# one of the actions to take to prepare the server for LON-CAPA |
|
# installation, then the output from &chkapachessl() will be |
|
# used to determined which file will contain VirtualHost configs. |
|
# |
|
# If there are no files containing VirtualHosts definitions, then |
|
# <VirtualHost *:443> </VirtualHost> blocks will be appended to |
|
# the standard Apache SSL config for the particular distro: |
|
# ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf |
|
# for SuSE/SLES, and default-ssl.conf for Ubuntu. |
|
# |
|
# Once a file is selected, the contents of sslrewrite.conf and |
|
# loncapassl.conf are compared with appropriate blocks in the file |
|
# and the user will be prompted to agree to insertion of missing |
|
# lines and/or deletion of surplus lines. |

## Copy loncapassl.conf and sslrewrite.conf |
|
## |
|
############################################### |
|
|
|
# |
|
# The Apache SSL configuration used by LON-CAPA is contained in |
|
# two files: sslrewrite.conf and loncapassl.conf. |
|
# |
|
# Starting with LON-CAPA 2.12, name-based virtual hosts are used |
|
# with port 443. The default virtual host (i.e., the one listed |
|
# first) is for the server's standard hostname, and that is the one |
|
# which will respond to client browser requests for https:// pages. |
|
# |
|
# Accordingly, a system administrator will need to edit the config |
|
# config file to include paths to a signed SSL certificate (public), |
|
# chain (public) and key (private) pem files. The certificate should |
|
# have been signed by a recognized certificate authority ((e.g., |
|
# InCommon or Let's Encrypt). |
|
# |
|
# The sslrewrite.conf file contains the rewrite configuration for |
|
# the default virtual host. The rewrite rules defined are used to |
|
# allow internal HEAD requests to /cgi-bin/mimetex.cgi to be served |
|
# http://, in order to support vertical alignment of mimetex images |
|
# (one of the options for rendering Math content); (b) allow requests |
|
# for certain URLs (external resource, and syllabus, if external URL |
|
# used) to be served http:// to accommodate the use of iframes which |
|
# would otherwise result in browser blocking of mixed active content. |
|
# |
|
# The loncapassl.conf file contains the configuration for the |
|
# "internal" virtual host, which will respond to requests for https:// |
|
# pages from other LON-CAPA servers in the network to which the node |
|
# belongs. The ServerName is internal-<hostname> where <hostname> |
|
# is the server's hostname. There is no need to create a DNS entry |
|
# for internal-<hostname>, as LON-CAPA 2.12 automatically performs |
|
# the required hostname to IP mapping. |
|
# |
|
# Requests to /raw on the "internal" virtual host require a valid |
|
# SSL client certificate, signed by the certificate authority |
|
# for the LON-CAPA network to which the node belongs. |
|
# |
|
# The configuration file to which the contents of sslrewrite.conf |
|
# and loncapassl.conf will be written will have either been identified |
|
# when &chkapachessl() was run, or if no files were found with |
|
# existing rewrite blocks, then a candidate file will be chosen |
|
# from the .conf files containing VirtualHosts definitions. |
|
# If there is more than one suitable candidate file, the system |
|
# administrator will be prompted to select from the available files. |
|
# |
|
# If there are no files containing VirtualHosts definitions, then |
|
# <VirtualHost *:443> </VirtualHost> blocks will be appended to |
|
# the standard Apache SSL config for the particular distro: |
|
# ssl.conf for RHEL/CentOS/Scientific/Fedora, vhost-ssl.conf |
|
# for SuSE/SLES, and default-ssl.conf for Ubuntu. |
|
# |
|
# Once a file is selected, the contents of sslrewrite.conf and |
|
# loncapassl.conf are compared with appropriate blocks in the file |
|
# and the user will be prompted to agree to insertion of missing lines |
|
# and/or deletion of surplus lines. |
