I am installing Qlik Catalog SW on Linux Read Hat Enterprise 7.9 following the instructions of the installation guide.
I have got the first problem in Tomcat Installation. Basically, I am not able to connect to Tomcat with the browser.
Below is a detailed list of commands I have used.
I have tried it using Firefox.
When trying to install Chrome I got other issues.
Any hints?
*** Installing Chrome ***
# sudo yum install glib
# sudo yum list glibc
# sudo wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
# sudo yum -y install redhat-lsb libXScrnSaver
# sudo yum -y localinstall google-chrome-stable_current_x86_64.rpm

Requires: libc.so.6(GLIBC_2.18)(64bit)
<<<<<<<<<<<<<<<<<<<<<<<
*** Installing Tomcat ***
Install wget (if not already installed):
# sudo yum install -y wget
Become the service account user:
# sudo su - qdcuser
Download Apache Tomcat and extract the file in usr/local/qdc:
$ cd /usr/local/qdc
$ wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.38/bin/apache-tomcat-9.0.38.tar.gz
$ tar -xvf apache-tomcat-9.0.38.tar.gz
Overwrite <tomcat home>/conf/server.xml with the version expanded from the Qlik Catalog zip file:
$ cp /tmp/podium/config/tomcat9-server.xml /usr/local/qdc/apache-tomcat-9.0.38/conf/server.xml
Opening ports 8080 and 8443:
# sudo firewall-cmd --zone=public --permanent --add-port=8080/tcp
# sudo firewall-cmd --zone=public --permanent --add-port=8443/tcp
# sudo systemctl restart firewalld.service
Setup Apache Tomcat as a service to automatically start when Linux restarts:
# sudo cp /tmp/podium/config/tomcat.service /etc/systemd/system/
# sudo systemctl daemon-reload
# sudo systemctl enable tomcat.service
Edit the file /etc/systemd/system/tomcat.service to insert the correct user and group names:
# sudo nano /etc/systemd/system/tomcat.service
User=qdcuser
Group=qdcgroup
Start Tomcat manually:
$ cd /usr/local/qdc/apache-tomcat-9.0.38
$ ./bin/startup.sh
Browse to the following URL to verify that Tomcat is running:
https://localhost:8443
>>>>>>>>>>>>>>>>>>>>
Unable to connect
Firefox can’t establish a connection to the server at localhost:8443.

I too see this issue.. Here is what I think the reason might be..
rpm -qf /usr/lib64/libc.so.6
glibc-2.17-325.el7_9.x86_64
glibc is 2.17 on RHEL 7.9 The developers at google should know this which means it is a bug.
Or. They should provide that library as part of their package and statically link it.
Short answer. For now, until Google figures it out and fixes, I might either remove the package, or skip that package.
To skip..
sudo yum -y update --exclude google-chrome-stable*
To remove... Well.. "sudo yum -y remove google-chrome-stable"
An alternative until google resolve the problem is:
sudo yum update --skip-broken
This can install all updates and ignore chrome

I am currently required to setup the new server running php7.2 and the server will have many background process for sending emails to customer. the recommendation I got was to use Gearman Job Server.
I have been searching but seems to have only post about gearman-job-server with php5 and below.
The process of installing Gearman Job Server with php7 will be covered in like 4 steps
Install and update the Gearman PPA
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:gearman-developers/ppa
sudo apt-get update
Install Gearman Job Server and some other required components and tools
sudo apt-get install gearman-job-server libgearman-dev php7.0-dev php-pear wget unzip re2c
sudo apt-get upgrade
Download, compile the gearman pecl module and add to php.ini
cd /tmp/
sudo wget https://github.com/wcgallego/pecl-gearman/archive/master.zip
unzip master.zip
cd pecl-gearman-master
sudo phpize
./configure
sudo make
sudo make install
echo "extension=gearman.so" | sudo tee /etc/php/7.0/mods-available/gearman.ini
sudo phpenmod -v ALL -s ALL gearman
Restart webserver or PHP FPM
sudo service php7.0-fpm restart
sudo service apache2 restart
If you are running a different version of PHP make sure you make the appropriate changes to the commands or directories mentioned above. ie “/etc/php/7.0/” to “/etc/php/7.1/” etc.
Thanks to techearl.com for their tutorial which can be found
Here
The answer by Ruberandinda Patience is correct and will work but since the gearman pecl module is packaged for Ubuntu there is a much simpler way to achieve the same thing:
apt install gearman-job-server php-gearman
I am trying to install openwhisk for dev mode using docker compose on Amazon Linux EC2 Instance. I am following this link for doing so https://github.com/apache/incubator-openwhisk -> Get Started.
Although, it has worked for me before once, in this installation, I am facing an issue. These are the steps I followed:
sudo yum update -y
sudo yum install -y docker
sudo service docker start
sudo chkconfig docker on
sudo yum install -y python-pip
sudo pip install docker-compose
This step is because open whisk is using sudo for docker-compose, and based on previous steps, sudo docker-compose -v gives a command not found.
sudo cp /usr/local/bin/docker-compose /bin
sudo yum install -y git
cd ~
git clone https://github.com/apache/incubator-openwhisk-devtools.git
cd incubator-openwhisk-devtools/docker-compose
sudo make quick-start
Update: The problem is that the make command gets stuck at the stage where it is waiting for invokers.
I have not made any changes to any source code, nor I did any other steps before this on the instance. It was a freshly created instance.
Am I missing something in OpenWhisk or EC2 or the combination of both? Any help would be great.
Update: I tried the docker-compose method for installing open whisk on Amazon Linux 1, Amazon Linux 2, Ubuntu 16.04 as well as Ubuntu 14.04. On all platforms, it got stuck at sudo make quick-start where it is waiting for invokers.
Update: Instead of using python-pip for docker-compose installation, used the command from docker website as well.
sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
if docker-compose command is not found it means you didn't install docker-compose correctly.
I don't think you can install docker-compose as a python library using pip
See the instructions here https://docs.docker.com/compose/install/#install-compose
someting like
sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
Or take a look at https://medium.com/#khandelwal12nidhi/docker-setup-on-aws-ec2-instance-c670ff3d5f1b
I made a simple custom docker setup for php development. So far everything works as expected. The only thing that I cannot figure out is why apache2 does not start automatically.
Here is my dockerfile:
FROM ubuntu:latest
RUN apt-get update && apt-get install -y apache2 php libapache2-mod-php php-mcrypt php-mysql php-cli php-curl php-xml php-intl php-mbstring git vim composer curl
COPY . /var/www/example
COPY vhost.conf /etc/apache2/sites-available/example.conf
RUN a2ensite example
RUN chown -R www-data:www-data /var/www/example/logs
RUN service apache2 restart
And here is my docker-compose.yml:
version: '2'
services:
app:
build:
context: .
dockerfile: Dockerfile
image: myexampleapp
ports:
- 8080:80
tty: true
And here is the output docker-compose up command:

It shows clearly that apache was restarted successfully. However it actually does not:

* apache2 is not running
I am new to docker, so all suggestions (even if they are not answering this specific question) to improve what I am doing so far are welcome.
Thanks
Docker services have to be running in the foreground. In your Dockerfile, RUN service apache2 restart will start apache as background process. Hence the container will exit.
To run apache in the foreground, add the following to the Dockerfile.
CMD ["/usr/sbin/apachectl", "-D", "FOREGROUND"]
FROM ubuntu:latest
RUN apt-get update && apt-get install -y apache2 php libapache2-mod-php php-mcrypt php-mysql php-cli php-curl php-xml php-intl php-mbstring git vim composer curl
COPY . /var/www/example
COPY vhost.conf /etc/apache2/sites-available/example.conf
RUN a2ensite example
RUN chown -R www-data:www-data /var/www/example/logs
CMD ["/usr/sbin/apachectl", "-D", "FOREGROUND"]
The above answer is probably correct that mentioned that you can start it with:
CMD apachectl -D FOREGROUND
With docker it is sometimes a good idea to use the absolute path to a binary. So for example maybe do this instead:
/usr/sbin/apache2 -D FOREGROUND
I had a look a bit on google to see what other people are doing. I found this example of a dockerfile where the guy mentions a script start.sh:
From here: https://github.com/jacksoncage/apache-docker/blob/master/Dockerfile
EXPOSE 80
ADD start.sh /start.sh
RUN chmod 0755 /start.sh
CMD ["bash", "start.sh"]
Here is the start.sh script: https://github.com/jacksoncage/apache-docker/blob/master/start.sh
Which simply just does:
#!/bin/bash
# Start apache
/usr/sbin/apache2 -D FOREGROUND
Unrelated tip:
Your dockerfile you need to pin the version for Ubuntu.
See: https://nickjanetakis.com/blog/docker-tip-18-please-pin-your-docker-image-versions
Let me know if this helps.
If it help you or anybody, i was preparing working example with complete docker-composer:
https://github.com/marekz/docker-composer-example
FROM ubuntu:18.04
EXPOSE 80
ENV TZ=Europe/Warsaw
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
RUN apt-get update
RUN apt-get upgrade -y
RUN apt-get install -y libapache2-mod-php7.2 php7.2 php7.2-cli php7.2-gd php7.2-intl php7.2-mbstring php7.2-mysql php7.2-xml php7.2-xsl php7.2-bcmath php7.2-zip php-apcu npm lynx
RUN apt-get install -y mysql-client composer screen tmux vim nano iputils-ping
ENTRYPOINT service apache2 restart && bash
By analyzing the statements, I found a solution to my error
File: Dockerfile
FROM debian
RUN apt-get update -qq >/dev/null && apt-get install -y -qq procps telnet apache2 php7.3 -qq >/dev/null
RUN useradd --user-group --create-home --shell /bin/false app
RUN mkdir /data && chown -R app /data && chmod 777 /data
COPY php.conf /etc/apache2/mods-available/php7.3.conf
RUN a2enmod userdir && a2enmod php7.3
Error:
To activate the new configuration, you need to run:
service apache2 reload
Solutions:
FROM debian -> FROM debian:10
The reason was some conflict between the debian system and the php version. The latest version of debian has a newer version of PHP (PHP 7.4 at that time).
I am very new to the guacamole project. I installed it following instruction online. But I am not able to login to the guacamole application. The instructions I followed are,
sudo apt-get update
sudo ufw enable
sudo ufw allow 22 && sudo ufw allow 8080
sudo apt-get install fail2ban build-essential htop libcairo2-dev libjpeg62-dev libpng12-dev libossp-uuid-dev tomcat7 -y

My user-mapping.xml file is configured as below,
<user-mapping>
<authorize username="sandesha" password="sandy" >
<connection name="RDP">
<protocol>rdp</protocol>
<param name="hostname">103.5.133.3</param>
<param name="port">22</param>
</connection>
</authorize>
</user-mapping>
When I hit localhost:8080/guacamole, I am getting one login screen, but if I enter the credential information I configured in user-mapping.xml, it is throeing invalid-credential error. How to resolve this?
The error you are getting indicates that the Guacamole application cannot find user-mapping.xml file. Normally, this file is stored in the following locations:
directory specified by system property guacamole.home
directory specified by environment variable GUACAMOLE_HOME
directory .guacamole located in the tomcat home directory
From the instructions you have posted it looks like you are using the last option. However, your directory is '.guacmole' with one 'a' missing. The two lines from your instructions should be:
sudo mkdir /usr/share/tomcat7/.guacamole
sudo ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat7/.guacamole
Hey guys i am having a big problem , i have a centos vps and and i want radius apache web server Authentication. but in these tutorial http://freeradius.org/mod_auth_radius/ , i do not know where i should enter this :
./configure --add-module=LOCATION/mod_auth_radius.c
( i tried that in "var/www" and "etc/httpd" but show me these error : -bash: ./configure: No such file or directory )
Please help me.
You'd have to run ./configure from your Apache source, wherever you built Apache from. Since it sounds like you're new to building stuff, I wouldn't recommend that you build Apache from source.
On Centos 7, I did the following to build it. First, I had to install a couple of packages for Apache development:
sudo yum -y install httpd-devel
sudo yum -y install openssl
sudo yum -y install openssl-devel
Then to build it I did:
cd /tmp
tar xvf mod_auth_radius-1.5.8.tar
cd mod_auth_radius-1.5.8
cp mod_auth_radius-2.{0,4}.c
sed s/remote_ip/client_ip/g -i mod_auth_radius-2.4.c
apxs -i -a -c mod_auth_radius-2.4.c
The sed it because the code doesn't compile right on Apache 2.4.
There, now you have a /etc/httpd/modules/mod_auth_radius-2.4.so ready to go.
