So I want to do SSL certification on HAProxy to make the connection secure. I started of downloading HAProxy through appstore but later found out that the installation package doesnt support SSL. So I downloaded HAProxy 1.5.14 and compiled it with USE_OPENSSL=1. when I do haproxy -vv I am able to see that SSL is enabled in it.
The issue that I am facing is that when I compile and then install the file by using the command (sudo make install), I am unable to find the haproxy.cfg. I dont know where it is so I am unable to configure and set the setting to the requirement.
The installation package that I got is from the HAProxy official site and I would like someone's help. Please advice me how to solve this issue.
Thank you,
Safiul Hasan
The default config file location is:
/etc/haproxy/haproxy.cfg
You can also search your system for the file with this command:
find / -name 'haproxy.cfg'
If haproxy is already running successfully you can find out what config file it is using by looking at the command that is used to run it:
ps x | grep haproxy
This will result in output like this:
28548 ? S 0:00 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg
The part after the "-f" is the path to the config file haproxy is currently using.
There are no default haproxy.cfg file, you have to create it from scratch.
Look for some samples on the internet to get one fitting your needs.
You can put your configuration file anywhere and ask to haproxy to use it by using the "-f" parameter.

I'm a little bit confused about https communication with influxdb. I am running a 1.8 Influxdb instance on a virtual machine with a public IP. It is an Apache2 server but for now I am not willing to use it as a webserver to display web pages to clients. I want to use it as a database server for influxdb.
I obtained a valid certificate from Let's Encrypt, indeed the welcome page https://datavm.bo.cnr.it works properly over encrypted connection.
Then I followed all the instructions in the docs in order to enable https: I put the fullchain.pem file in /etc/ssl directory, I set the file permissions (not sure about the meaning of this step though), I edited influxdb.conf with https-enabled = true and set the path for https-certificate and https-private.key (fullchain.pem for both, is it right?). Then, systemctl restart influxdb. When I run influxdb -ssl -host datavm.bo.cnr.it I get the following:
Failed to connect to https://datavm.bo.cnr.it:8086: Get https://datavm.bo.cnr.it:8086/ping: http: server gave HTTP response to HTTPS client
Please check your connection settings and ensure 'influxd' is running.
Any help in understanding what I am doing wrong is very appreciated! Thank you
I figured out at least a part of the problem. It was a problem related to permissions on the *.pem files. This thing looks weird because if I tip the following, as documentation says, it does not connect.
sudo chmod 644 /etc/ssl/<CA-certificate-file>
sudo chmod 600 /etc/ssl/<private-key-file>
If, instead, I tip the second line with 644 all works perfectly. But this way I'm giving to anyone the permission to read the private key! I'm not able to figure out this point.
UPDATE
If I put inside /etc/ssl/ the symlinks that point to the .pem files that live inside /etc/letsencrypt/live/hostname the connection is refused. Only if I put a copy of the files the ssl connection starts.
The reason I am willing to put the links inside /etc/ssl/ is the automatic renew of the certificates.
Anyone can help?
I installed a brand new DigitalOcean droplet using a marketplace base (so on paper everything should be OK out of the box).
When trying to issue certificates, i am getting this error:
[11.13.2019_04-48-28] /root/.acme.sh/acme.sh --issue -d thehouseinkorazim.co.il -d www.thehouseinkorazim.co.il --cert-file /etc/letsencrypt/live/thehouseinkorazim.co.il/cert.pem --key-file /etc/letsencrypt/live/thehouseinkorazim.co.il/privkey.pem --fullchain-file /etc/letsencrypt/live/thehouseinkorazim.co.il/fullchain.pem -w /home/thehouseinkorazim.co.il/public_html --force

[11.13.2019_04-48-34] Trying to obtain SSL for: thehouseinkorazim.co.il and: www.thehouseinkorazim.co.il
I checked and UFW is not installed.
I do have a network firewall but it is the same one as another droplet that does allow for certificates (same rules) so I think it is not the cause.
I searched all the answers online and no luck.
I even installed certboot to manually issue certificate but same error (i did it because I know you need to register initially to get certificates and I haven't so I thought it was the cause).
Any ideas? Thanks!
update: i did a clean droplet again, this is the issue without anything I did manually:
Cannot issue SSL. Error message: ln: failed to create symbolic link '/usr/local/lsws/admin/conf/cert/admin.crt': No such file or directory ln: failed to create symbolic link '/usr/local/lsws/admin/conf/cert/admin.key': No such file or directory 0,283 Failed to obtain SSL for domain. [issueSSLForDomain]
I checked and there is no folder "cert" under "conf" in the path written above.
There's an known SSL issue on recent version due to some environment/code changing. We already aware it and submitted a new version which has that issue fixed included. Please give it a day or two and you should be able to launch the new version from marketplace which comes with CyberPanel v1.9.2.

I'm trying to start ProFTPD Server but i recieve the next message:
Starting proftpd (via systemctl): proftpd.serviceJob for proftpd.service failed because the control process exited with error code.
See "systemctl status proftpd.service" and "journalctl -xe" for details.
failed!
And when i get more information about it, i have:
fatal: TLSRSACertificateFile. '/etc/ssl/certs/proftp.crt' does not exists on line 8 '/etc/proftpd/conf.d/virtualmin.conf/'
I have to say i did'nt installed ProFTPD Server because this module came with the webmin installation.
Hope you can help me to know why proftp.crt fie does not exists and how can i fix this issue.
Thanks.
Don't know Webmin (I used it once approximalety 20 years ago..) but there should at least be options to disable TLS for the FTP Server and to change the path to the certificate if it is able to manage ProFTPD for You.
Other alternative (better then turning SSL/TLS off): copy Your cert for the server there (you have to do something similiar for the key I assume), if You do not have one You can get one or create Your own self-signed (not sure whether Webin can help You with that, but on command line it's pretty simple to create one with openssl.)
Come on...
1 - Check if your plugin is active in VirtualMin.
1.1 - Shell check if your SFTP is installed
== ProFTPD install
UBUNTU = apt install proftpd -y
CENTOS = yum install proftpd -y
2 - Check if your domain is SFTP enabled.
3 - Create an SSL within the domain, after created click on the option to use SSL for SFTP.
VIRTUALMIN // Domain >> Server Configuration >> SSL
4 - Create an SSL for the domain you use to access WebMin.
E Use this SSL for WebMin // VirtualMIn
5 - Check the proftpd settings via WEBMIN.
Good luck! Send news about your progress ...
I am trying to create localhost Apache Ambari cluster on CentOS7. I am using Ambari 2.2.2 binaries downloaded and installed from the Ambari repository with the following commands
cd /etc/yum.repos.d/
wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.2.2.0/ambari.repo
yum install ambari-server
ambari-server setup
ambari-server start
Before starting the server I have done all the necessary preparations steps described on the Hortonworks including the setup of passwordless ssh, which is frequent reason of problems according to the posts found on the internet. I verify it with
ssh root#localhost
During the creation of cluster in the "Install options" window I enter the name of the host I want to create (localhost in my case) and have already tried both of the options, which are
providing rsa secret key direktly - in this case the next window
simply stucks in the "Installing" stage and does not go any further,
showing no errors
performing manual registration of hosts.
For the second option I have downloaded and installed ambari-agent
yum install ambari-agent
ambari-agent start
In case of manual host registration I am getting the following error
"Host checks were skipped on 1 hosts that failed to register.".
When I click on "Failed", which in some cases described over the internet is supposed to deliver more precise description of a problem I see the following
"Registering with the server...
Registration with the server failed."
As a result I don't even now where to start searching for the possible reasons of this error.
Ambari cluster nodes need to be configured with a Fully Qualified Domain Name (FQDN). localhost is not an FQDN. You will need to configure the node with an FQDN and then retry the installation. You could use something like: localhost.local which is an FQDN. This requirement and how to configure the node to meet it are documented in the pre-requirements. From the HDP documentation:
All hosts in your system must be configured for both forward and and reverse DNS.
If you are unable to configure DNS in this way, you should edit the /etc/hosts file on every host in your cluster to contain the IP address and Fully Qualified Domain Name of each of your hosts.
I had the same "Registering with the server... Registration with the server failed." problem just recently.
I found the response on the same topic recommending to take a look at the log file which is located here /var/log/ambari-agent/ambari-agent.log from there was able to check that the hostname was set up incorrectly during some other phase of installation (I had it something like ambari.hadoop instead of localhost). So I went to the /etc/ambari-agent/conf/ambari-agent.ini and fixed it there.
I know that I'm digging some quite old question, but seems that compiling all that at one place might help someone with the same problem.
I am trying to understand the process of installing a letsencrypt certificate on Apache on Centos.
I have read the installation instructions, cloned the git repository, and there I’m stuck.
Has anybody had experience with this and what to do next?
Thanks
You didn't really make it clear what your error was, but I'll take a guess and say that you left off with cloning the Git repository.
From here, you'll need to run some commands with the letsencrypt-auto program that you just cloned to actually obtain a certificate and install it. Let's Encrypt and their automatic configuration feature isn't necessarily stable yet, so I recommend running the command to only obtain a certificate, then manually configure SSL yourself. Head into the directory that you cloned the Git repository to and run the following commands:
chmod +x letsencrypt-auto
./letsencrypt-auto certonly
Let's Encrypt will begin to download its dependencies and a prompt will finally appear requesting which domains you want a certificate for. Just fill it in and press enter. If all goes well, you'll get an output that looks similar to this:
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/example.com/fullchain.pem. Your
cert will expire on 2016-03-08. To obtain a new version of the
certificate in the future, simply run Let's Encrypt again.
This path will differ from my path since I'm running Ubuntu 14.04. Note the path to the folder, which will hold all of the files you need. Now, head into your Apache configuration and edit the configuration file to link to the SSL certificates that you just created, restart Apache, and you should be good to go!
If you need any further instructions, let me know.
