I tried setting password of database but it wasn't connecting to it .
it took my 3 days for getting how to install mysql on EMR
Install MySQL using the following command:
sudo yum install mysql-server -y
Start the MySQL service using the following command:
sudo service mysqld start
Set a root password for MySQL using the following command:
sudo mysqladmin -u root password yourpassword
Optionally, you can secure your MySQL installation by running the secure installation script using the following command:
sudo mysql_secure_installation
This script will prompt you to set the root password, remove anonymous users, disallow root login remotely, remove the test database, and reload the privilege tables.
I'm trying to deploy Moodle into Docker.
Here is the steps I followed:
First, create a new network for the application and the database:
$ docker network create moodle
Then, start a new database process in an isolated container:
$ docker run --name mysql --network moodle -e MYSQL_ROOT_PASSWORD=password -d mysql
Finally, you can run this moodle image and link it to your mysql container:
$ docker run --name my-moodle --network moodle --link mysql:database -p 8080:80 -d aesr/moodle
Access it via http://localhost:8080 or http://host-ip:8080 in a browser.
But while installing moodle I'm getting this error:
Data directory (/var/www/moodledata) cannot be created by the installer.
Maybe because of Apache doesn't have the proper permission. I'm running Docker on Windows.
My solutions worked on Centos 7.
Just move out the moodledata to somewhere else, like
mkdir /moodledata
chown -R apache:apache /moodledata
Because it calls the folder /var can be expose from internet and not accept to start the Installation
I use Ubuntu 18 as WSL and everything was running well. Today I run the apache and started the application. When the app tried to perform chmod() on a file which was submited through form inside the folder project (I use Laravel), I received the following error:
chmod(): Operation not permitted
I have notice that this error happen when I try running chmod() from web server (www-data user). In the cli I dont have problems.
From other posts over the net, I understand that Windows has some changes regarding WSL permissions and drive mounts. But I didnt get answer or didnt succeed to resolve that issue.
sudo umount /mnt/c
sudo mount -t drvfs C: /mnt/c -o metadata
Reference: https://github.com/Microsoft/WSL/issues/3172#issuecomment-389157376
sudo umount /mnt/c
sudo mount -t drvfs C: /mnt/c -o metadata,uid=1000,gid=1000,umask=22,fmask=111
did the trick for me.

When using the db2setup (Wizard) to install a new version of DB2 V10.5.0.3 (or the universal fixpack V10.5.7) the installer appears to hang near the end of the Create DB2 Administration task. There is a das directory created in the /home/dasusrX directory but it has no visible files. The logs show no errors. Manually trying to create the DAS also hangs using dascrt -u dasusrX
In the console where I launched the db2setup I found I needed to enter the dasusrX password a couple of times. There is no prompt displayed. I believe the system also hangs during the Configuring DB2 instances task and luckily I used the same password for other users so I entered it there as well to complete the install.
I figured this out running the dascrt -d -u dasusrX and saw it hung at the su dasusrX -c /bin/pwd command and when I tried that command manually, it propmted for the dasusrX password. This may be a unique situation for our server set up as root is accessible only via sudo -i so perhaps in other situations there would be no prompt for dasusrX password when using su as root.
Though I have followed the usual steps for using the dotCloud CLI under Cygwin, dotcloud push fails in all cases: --rsync, --hg, and --git.
I am on Windows 8 and Cygwin.
How can I push successfully?
Sample output:
me#host /cygdrive/d/project
$ dotcloud push --rsync
==> Pushing code with rsync from "./" to application myapp
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at /home/lapo/package/rsync-3.0.9-1/src/rsync-3.0.9/io.c(605) [sender=3.0.9]
me#host /cygdrive/d/project
$ dotcloud push --git
Permission denied (publickey,password).r from "./" to application myapp
fatal: The remote end hung up unexpectedly
me#host /cygdrive/d/project
$ dotcloud push --hg
==> Pushing code with mercurial from "./" to application myapp
abort: no suitable response from remote hg!
Error: Mercurial returned a fatal error
You may be running into a bug in Cygwin's group permissions. Vineet Gupta gives a workaround in his blog. The problem comes from the very strict permissions expected by ssh around the keys, and the solution is to set the permission on the ssh key properly (to 600, rw by owner only). Cygwin seems to need the group to be added manually.
Updating the steps to get the dotCloud CLI installed, including setting the permissions, leads to:
Start the Cygwin Setup.
Select default choices until you reach the package selection dialog.
Enable the following packages:
net/openssh
net/rsync
devel/git
devel/mercurial
python/python (make sure it’s at least 2.6!)
web/wget
After the installation, you should have a Cygwin icon on your desktop. Start it: you will get a command-line shell.
Download easy_install
wget http://peak.telecommunity.com/dist/ez_setup.py
Install easy_install
python ez_setup.py
You now have easy_install; let’s use it to install pip:
easy_install pip
Now install dotcloud (the CLI)
pip install dotcloud
Set up the CLI with your credentials. This will also download the ssh key.
dotcloud setup
New Step Update the permissions on your dotCloud key:
chgrp Users ~/.dotcloud_cli/dotcloud.key
chmod 600 ~/.dotcloud_cli/dotcloud.key
Now you should be able to dotcloud push
If you have multiple dotCloud accounts, then you will need to repeat this process for each account, since each account has its own key. Also note that you shouldn't have to set these permissions manually, but it seems like the group ownership is sometimes the wrong default in Cygwin. Linux and OSX don't seem to show this problem, though the permissions must be 600 for all OSes, so it is worth checking.
