Ping, SSH, FTP are OK, HTTP Not OK

My problems started when I was in the process of backing up one of my domains and the server froze. I had to re-boot the server. After the re-boot all my problems began.

For the last few days I’ve been having problems with my server. One of the problems I got resolved was the backup failures I had. Whenever I tried to back up a domain it will tell give me several error messages that I tracked down to a space allocation issue. I fixed that and now I can back up my server normally.

Now I am left with one more issue and that is that my sites are not up.

I can ping the IP addresses and I can ping the domain name. I can receive mail, I can connect with FTP/SSH But I cannot connect with HTTP.

Does anyone know how to proceed here and fix the site?

Thanks
 
Log in to SSH
Type the following commands
Paste the output here

/etc/init.d/httpd status
/etc/init.d/httpd configtest

If the HTTPD is up and running & the config is okay. Try /etc/init.d/httpd restart.

Post the results back here. Can you also PM me the ip address? I'll take a look.
 
Thanks raaqi for your response.

Here is what the output:

[root@www ~]# /etc/init.d/httpd status
httpd is stopped

[root@www ~]# /etc/init.d/httpd configtest
Syntax error on line 86 of /etc/httpd/conf.d/ssl.conf:

There you go. You have an error in your ssl.conf. Sort it out.

Paste the configuration file here and i'll have a look.
 
ssl.conf file:

#
# This is the Apache server configuration file providing SSL support.
# It contains the configuration directives to instruct the server how to
# serve pages over an https connection. For detailing information about these
# directives see <URL:http://httpd.apache.org/docs-2.0/mod/mod_ssl.html>
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.

# Server Certificate:

# Access Control:
# With SSLRequire you can do per-directory access control based

#<Location />

# and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \

# and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
# and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20 ) \
# or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#</Location>

# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This means that
# the standard Auth/DBMAuth methods can be used for access control. The
# user name is the `one line' version of the client's X.509 certificate.
# Note that no password is obtained from the user. Every entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "SSLRequireSSL" or "SSLRequire" applied even
# under a "Satisfy any" situation, i.e. when it applies access is denied
# and no other module can change it.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-s
 
Add this to the rest of your ssl.conf file. Then type:

/etc/init.d/httpd configtest

if it goes well

/etc/init.d/httpd start

# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
SetEnvIf User-Agent ".*MSIE.*" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0

# Per-Server Logging:
# The home of a custom SSL log file. Use this when you want a
# compact non-error SSL logfile on a virtual host basis.
CustomLog logs/ssl_request_log \
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Glad it worked mate. Just remember to look at your logs and the error messages when you're starting a program. They will lead you in the right direction.
 
BEATIFUL!!!!!!

That did the trick. I am able to access my sites via HTTP.

I really appreciate the your help. I hate to bother you again, but can you tell me why or what happened.

This is how it all started. I was doing a backup using the plesk control panel and the whole server just froze. I had to use my hosting service tool to remote re-boot. Ever since then it all went to hell.

Again I really appreciate your help.
 
No idea. You'd have to go looking in your logs to find out.

A part of your config file was removed, i'm not sure how that could happen.

I'm glad you have everything back up and running. Bye for now
