I just downloaded mongodb via homebrew. When I tried starting it by mongod it said that I didn't have the data/db folder for it. I made the folder via sudo command from another stackoverflow page. Now the error that I'm getting is:
exception in initAndListen: 10309 Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating
I'm not sure why it's asking me if another instance of mongod is running because I only have one bash shell open.
Any tips would be awesome. Thank you!
Okay, I figured it out. The command after sudo mkdir -p /data/db is
sudo chown $USER /data/db

I am trying to install Testlink on OS X for Mac. However, I am getting the following message which will not let me continue with installation. I have seen solutions for other operating systems but not for Mac. I am inexperienced with Mac. Any help appreciated. Thanks!
I resolved it..
chmod 777 /Applications/XAMPP/xamppfiles/htdocs/testlink-1.9.16/gui/templates_c
sudo mkdir /var/testlink/logs/
sudo mkdir /var/testlink/upload_area/
Then give the last two directories writeable permissions:
sudo chmod 777 /var/testlink/logs/
sudo chmod 777 /var/testlink/upload_area/
Check whether the /var/www/html/testlink/gui/templates_c directory is writable (logged with the user used to run the webserver process).
To resolve this issue try to follow steps:
ssh into the machine you are installing
move to the testlink main directory, in my case: cd /var/www/html/testlink/gui
change the permision of templates_c: sudo chmod a+w templates_c
Now try to install testlink again.
I installed elasticsearch this way :
retrieved the tar.gz on windows, extracted it and put it on a zip
uploaded the zip over ssh on a server and use 'unzip file' to unzip it.
I modified the elasticsearch file so that it has this line
export JAVA_HOME = "/home/xxx/project1/jdk1.8.0_73_linux64"
just below
#!/bin/sh
now when I go into /home/xxx/project1/elasticsearch/bin and type
./elasticsearch
I get
-bash: ./elasticsearch: Permission denied
What could I do to get more information about the problem?
I'm logged as user xxx
Thanks.
The problem is, that you've installed elastic being logged in as root. Now you're surely logged in as not root. If you're working as a user with root privileges, you potentially could start elastic, but it tells you, you can't run in as root. The owner of your elastic folder is root (he installed it). So, all you need to do is to change the owner of a folder to your xxx-user (to let him run elastic). You can easily do it executing a command:
chown -R new_owner path
for example, user is xxx and path is /opt/elasticsearch-2.3.5:
chown -R xxx /opt/elasticsearch-2.3.5
"-R" parameter ensures, that not only folder, but all files inside will recursively change the owner you provide.
Try to install using the package Yum Install for elasticsearch.
Else try: Its sounds like the user permission to access the files.
Ensure that you have downloaded the linux distribution (Optional) Since you have mentioned its tar.gz.
If you have extracted using sudo command then you need to change the user permission for elasticsearch folder to logged in user OR start the elasticsearch using sudo command
sudo ./elasticsearch -d
Check the execution permission if not please do the same by following command
sudo chmod +x /home/xxx/project1/elasticsearch/bin/elasticsearch.sh
Try this things if not please create a chat window and invite me.
Looking ahead I will immediately say that the ES app doesn't work using the sudo
In my case with ES 6.8.1 version on ubuntu i solved the problem using this steps:
Add the current user(or any other) to ES group:
sudo adduser <yourName> elasticsearch
Add possibility to execute ES:
sudo chmod +x /usr/share/elasticsearch/bin/elasticsearch
Then i changed owner of some paths**, in my case these were:
sudo chown -R <yourName>:elasticsearch /etc/default/elasticsearch
sudo chown -R <yourName>:elasticsearch /etc/elasticsearch
sudo chown -R <yourName>:elasticsearch /var/log/elasticsearch
**I started the application several times and then looked where I had no permission
Then i started ./usr/share/elasticsearch/bin/elasticsearch and saw the long-awaited JSON on port 9200 :)
Hope this will help someone.
I'm trying to write a command on mac terminal using the root, but it shows me that the permission denied, when I use the sudo it shows that the command not found
can any one please help me
aftheers-MacBook-Air:scripts root# ./ArduinoWifiShield_upgrade.sh
-sh: ./ArduinoWifiShield_upgrade.sh: Permission denied
You have to make the file executable:
chmod +x ArduinoWifiShield_upgrade.sh
To avoid permission denied prompt, type this command and continue
sudo su
Install the packages in this admin mode,
then go back to normal mode
exit
I have installed PostgreSQL using the EnterpriseDB installation.
I ran sudo ./postgresql-9.3.5-3-osx.app/Contents/MacOS/installbuilder.sh --mode unattended and then ran open /Applications/TextEdit.app .profile to edit my .profile file newly created in /Users/Dhruv to add the line source /Library/PostgreSQL/9.3/pg_env.sh.
Running createuser Dhruv --pwprompt --username=postgres I got
-bash: createuser: command not found
Then running unknown-88-1f-a1-1b-c2-ec:9.3 dhruv$ sudo -u postgres /bin/createuser and various other methods I was able to set up something using some sort of password prompt. I know this later because using sudo -u postgres /Library/PostgreSQL/9.3/bin/createuser I got
createuser: creation of new role failed: ERROR: role "postgres" already exists
Running then initdb -D /Library/PostgreSQL/9.3/data I get
-bash: initdb: command not found.
Similiarly, if I try the same thing but while connected to postgres, sudo su - postgres and then initdb -D /Library/PostgreSQL/9.3/data I get again
-bash: initdb: command not found.
At a loss at what to do. 1) how do I know details of this supposed role "postgres" I created magically and 2) why is initdb not working?
How I fixed this is run brew doctor, and you might see the postgresql un der the Warning: that indicates there's unlinked kegs in your Cellar.
Try to run brew link postgresql. It will show some symlinks got created. Then run init db ... again.
Hope this help!
Who are you logged in as?
When you do sudo or su -, it will run init scripts for root, such as .bashrc and .bash_profile.
These may set up difference executable search paths between root, postgres, and you.
Try something like sudo initdb, or su - postgres -c initdb ... whichever user has the paths constructed correctly, so that the path gets set up.
You could also duplicate the path/lib creation code in your own environment, but that will break if it is ever changed.
Same thing happened to me. I'm new to OS X coming from Linux, here's what I had to do. I installed postgres via homebrew and when I did so I noticed it put everything it download to: /usr/local/Cellar/postgresql/($postgres_version)/
When I cd'd into that folder I saw a directory named bin so I cd'd and saw initdb right there. So I had to then add this to my path so I could use the command:
$ export PATH=/usr/local/Cellar/postgresql/9.4.4/bin:$PATH
hope that helps you
i'm trying to learn mongo db on my mac. I installed mondgo db using homebrew and it appeard successful. I created the dir /data/db. when I type mongo into the terminal I get:
Error: couldn't connect to server [a bunch of numbers] at src/mongo/shell/mongo.js:145 exception:connect failed
I looked at the following answer on SO: Installing and Running MongoDB on OSX
in the check answer it says:
1) Start a terminal for your mongo server
2)Go to mongo/bin directory
What does it mean to start a terminal for your server? does that mean just open up a new terminal window?
Where can I find the mongo/bin directory?
Any other suggestions on getting mondoDB up and running would be appreciated.
you should read the documentation here: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
And follow the instructions.
In this case the [bunch of numbers] are the hostname/ip and port number that the binary mongo has tried to connect to. What it's telling you is that there is no mongod binary listening on the hostname and port that mongo is trying to connect to.
You will need to start mongod before you are able to connect to it with a mongo shell. The documentation above outlines this further.
If you use homebrew the mongodb binaries will automatically be put on your path which means you won't need to cd into another directory like mongo/bin.
Good luck.
Probably you run the mongodb first time. Based on the documentation you must follow a few steps and then you are ready to go.
First, create main db directory:
sudo mkdir -p /data/db
Make sure that you have a read and write permission on that directory:
sudo chown `id -u` /data/db
And to listen to default port, run:
mongod
Finally keep in mind that after the run "mongod" command do not close console tab. Open a new tab (Cmd + T) and run other commands on the new window. To close the mongod session simply hit the Ctrl + C on the previous tab.
when everything mentioned above did not work. I did the following thing (in Mac)
cd ~
mkdir -p data/db
After creating directory in home(which will be definitely allowed) most imp command is below
mongod --dbpath ~/data/db &
So that it could take the path of db which was in home directory (as we are not able to create in / dir.
To avoid it running frequently, put the above command in .bash_profile file in home directory so that it will automatically run the above command whenever we try to use terminal in Mac
Note: Whenever we open the terminal it will execute the above command so that we can access the mongodb (I understand this should be taken place in background but it works fine)
We need to press enter/return key to get the regular command line terminal and continue doing our work
These steps worked for me well on Mac, you can give a shot, make sure you install brew first and put these lines in terminal line by line:
brew update
brew install mongodb
brew install mongodb --with-openssl
brew install mongodb --devel
sudo mkdir -p /data/db
sudo chown -R [your username] /data/db
(Replace with your username with what you can get by typing whoami in the terminal)
mongod
Run you app, for example localhost:8000
