Followed below mentioned steps to install kafka
Installed Apache kafka from kafke.apache.org
Have java8 already installed on my mac machine
Extracted kafka
Able to do cd kafka_2.13-2.7.0 and bin/kafka-topics.sh
But when I'm adding kafka in the bash_profiles then kafka is not added globally
nano ~/.bash_profiles
export PATH="$PATH:/mydirectorypath/Kafka_2.13-2.7.0/bin"
But when i'm trying to use kafka globally it doesn't work.
I'm new to mac and kafka both so I'm not sure what I'm doing wrong is it the correct way to add paths in mac since in the first place i couldn't find existing bash_profiles using cat ~/.bash_profile
But after creating the one using nano ~ /.bash_profile i can see the content.
If i'm trying to do
Kafka-
It says zsh:command not found:kafka-
:is it the correct way to add paths in mac since in the first place i couldn't find existing bash_profiles
That export command is the correct way to set the path, however, according to the error, you're using ZSH, which does not use .bash* files. You'd need to edit .zshrc or change your default terminal back to Bash. You'd also need to start a new terminal after editing those files
To verify the PATH works, you'd do which kafka-topics
If you want to install Kafka on a Mac, just do brew install kafka. Then to run a broker, you can use brew services command with Zookeeper and Kafka to start/stop the servers, and your PATH will already have all the shell scripts - https://brew.sh
Note: The above are all local variables to your user account. Globally would imply the commands are available to any user logged in to your machine

On my previous Mac laptop I was able to run elasticsearch in terminal in any directory with the command "elasticsearch". Now I have to scroll to the elasticsearch install directory and run a particular file.
Could someone help me set up a command so I can just type "elasticsearch" wherever I am, and the service will start to run, as it was previously?
You can simply create an alias in your mac profile(latest version of mac uses .zshrc) like below.
Assuming you have installed Elasricsearch using the tar file as you mentioned you have to go to a particular dir(bin) in this case.
alias elasticsearch='./path/to/bin/foler/elasticsearch'
Please note, you need to run source ~/.zshrc to make sure alias is loaded. Let me know if you face any issue, help to help further.
I am trying to install gcloud SDK while using a coporate network which works behind a proxy (and a VPN sometimes). I get proxy settings automatically using a pac.fcgi file (Automatic Proxy Configuration).
Now when I try to run ./install.sh in the terminal, I am constantly getting the following error
➜ google-cloud-sdk ./install.sh

Do you want to help improve the Google Cloud SDK (Y/n)?
ERROR: (gcloud.components.list) Failed to fetch component listing from server. Check your network settings and try again.
I found this SO question which was having the same issue, but their problem was related to ipv6. I already have ipv6 disabled (I can't even enable it) and I am using ethernet to connect to the network. Thus the answer is not useful to me.
I searched for proxy related info about installation and found this page. It asks for using a non-interactive installer instead and using gcloud command to set the proxy after installation. My problem is that I can't even install gcloud. I have tried with both interactive and non-interactive installers.
Any way I can install gcloud while being behind a corporate proxy.
PS: I am on macOS High Sierra and using zsh shell (already tried bash), in case it matters.
So, the problem was I was unable to set proxy before installation of gcloud. The installation of gcloud basically set the CLI in the path and installs some required components (core, bq, gsutil etc).
So what I did is I added the following lines in my .zshrc
source <PATH to gcloud sdk>/google-cloud-sdk/path.zsh.inc
source <PATH to gcloud sdk>/google-cloud-sdk/completion.zsh.inc
or if you're using bash, add these lines in your .bashrc or .bash_profile
source <PATH to gcloud sdk>/google-cloud-sdk/path.bash.inc
source <PATH to gcloud sdk>/google-cloud-sdk/completion.bash.inc
After that I restarted the terminal (or just run source ~/.zshrc or source ~/.bashrc or source ~/.bash_profile on terminal)
Now I was able to use gcloud commands. I ran gcloud init, set the proxy and then installed the required components using the following command -
gcloud components install core bq gsutil
And I installed gcloud without using the install.sh script.
PS: Run scutil --proxy to know the proxy settings set in your system.
For Windows 10 users who experience this issue. I installed the google SDK from the archived versions page. then used git bash to install using ./google-cloud-sdk/install.sh. then added in environment variable manually to PATH to use commands.
Trying to install Glassfish(Java EE App. Server) and Wildfly App Server using Homebrew .
http://macappstore.org/wildfly-as/
http://macappstore.org/glassfish/
used these above mentioned tutorials .
I got the following errors while trying to run them by typing just "glassfish" & "wildfly-as" respectively.
Output(Error):
-bash: glassfish: command not found
-bash: wildfly-as: command not found
Searched about it and I think it has something to do with $PATH. I don't understand $PATH Variable . Need help.
The issue is that there are two asadmin scripts. One at $GLASSFISH_HOME/bin and one at $GLASSFISH_HOME/glassfish/bin
Here are full instructions to get your domain up
brew update
brew install glassfish
you should see message, add that line to your .bash_profile
==> Caveats
You may want to add the following to your .bash_profile:
export GLASSFISH_HOME=/usr/local/opt/glassfish/libexec
Open a new terminal then, cd $GLASSFISH_HOME/glassfish/bin
./asadmin start-domain --verbose
Browse to http://localhost:8080 for welcome page and http://localhost:4848 for admin console
I actually installed Wildfly-Application Server using homebrew but could not find a way to run it.
https://tomylab.wordpress.com/2016/07/03/how-to-install-wildfly-on-mac/
This tutorial helped me .
And for glassfish, my installation was again successful using homebrew but was not able to run it . I did figure it out when I ran the following commands.
$ cd /usr/local/opt/glassfish/libexec/bin
$ ./asadmin
asadmin> start-domain
You need to understand about the PATH variable. It is an environment variable on Unix-like operating systems, specifying a set of directories in which executable programs are located. In general, each executing process, or user session, has its own PATH setting.
So, you need to add the glassfish home path to your actual path variable.
Now, as per your problem with running the Glassfish server; try this:
export GLASSFISH_HOME=/usr/local/opt/glassfish/libexec/
export PATH=$PATH:$GLASSFISH_HOME/bin
Add it to your bash profile, if you do not want to do this everytime.
I have installed mongodb for mac os through 10gen and I have gone through the documentation to do so. Everything seems fine apart from the configuration file. I can not see it in /etc/mongod.config. Do I have to manually create this config file? And if so how can I go about it?
cheers
The default path for brew installed mongodb on Mac OS X is /usr/local/etc/mongod.conf
Unless you have installed a packaged version of MongoDB (for example, using Homebrew or Mac Ports) you will have to create a config file manually, or just pass the appropriate command line parameters when starting up MongoDB.
If you want a commented example of a config file to start with, the mongodb.conf in the Debian/Ubuntu package should be a good starting point. Important options to check are the dbpath and logpath which will likely be different for you.
It would also be worth looking at the Homebrew mongodb formula which includes setting up a LaunchAgent script to manage the mongod service.
Yes, unless you install via a package manager (like apt or yum on Linux) you have to create this manually. Then, When you start mongod you simply need to specify where the config file is, for example:
./mongod -f /path/to/mongod.conf
For how that file should look, just take a look here:
http://docs.mongodb.org/manual/reference/configuration-options/
You can also see the aforementioned Linux config files from the packages on github:
https://github.com/mongodb/mongo/blob/master/rpm/mongod.conf
https://github.com/mongodb/mongo/blob/master/debian/mongodb.conf
In the case you installed MongoDB without Homebrew, i.e. downloaded the TGZ package directly from MongoDB Download Center, you will can add the configuration file:
sudo nano /etc/mongod.conf
Please use only spaces (no tabs) in the file and leave a space after the key. For example:
security:
authorization: enabled
net:
port: 27017
bindIp: 0.0.0.0
And then run the instance with the configuration flag:
mongod -f /etc/mongod.conf
I wrote a post about installing MongoDB Community Edition directly from the TGZ archive.
I am using Mac OSX Lion. I am running php ver 5.3.6 through MAMP and when trying the create a AMQPConnection I get this error
Class 'AMQPConnection' not found
I installed rabbitmq through macports using this command
$ sudo port install rabbitmq-server
I run the server using this command
$ sudo rabbitmq-server -detached
It all works fine
I added "extension=amqp.so" to my php.ini file. More specifically my /Applications/MAMP/bin/php/php5.3.6/conf/php.ini file.
I have rabbitmq-c
I ran autoreconf -i && ./Configure && make && sudo make install with no errors
I configured rabbit with this command phpize && ./configure && make && make install
All that seemed to go perfectly.
I even created my user with permissions and verified those permissions with the web plugins that can be accessed through localhost:55672
I even tried copying amqp.so into my /Applications/MAMP/bin/php/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626/ file in a futile attempt to get it working.
Everything that I have done has seemed to work flawlessly. I get no error/warning messages. The Rabbit server is running. I ran it without the -detached option to see if I was getting any errors there. Nothing.
Any Suggestions??????
Best way to test your RabbitMQ Server installation is by testing with simple python code.
Installing PIKA library on Mac OSX is very easy. Follow the steps given here.
http://www.rabbitmq.com/tutorials/tutorial-one-python.html
copy paste and create two python files receive.py and send.py. Execute these from two terminal windows. In about 10 minutes you'll know that RabbitMQ is able to receive the message and queue.
Create the info.php on server with
Check the results from browser if it shows AMQP library is active.
I feel your RabbitMQ server is installed, but PHP library is not getting loaded correctly.
Check your error.log. There must be some details why it is failing to load 'amqp.so' file.
Can You please Add:
use PhpAmqpLib\Message\AMQPMessage;
under your:
use PhpAmqpLib\Connection\AMQPStreamConnection;
line and it will work.
