Nginx: 413 - Request Entity Too Large Error and Solution - nixCraft
Encountered this with huge uploads even though I changed the PHP post and upload max size settings. It turned out, I had to also set client_max_body_size in my nginx virtual host file.

Solving the Error: route [login] not defined in laravel 5.5
This is important if building an api with Passport on Laravel5.

Also, if using a roles and permissions library such as the Spatie Laravel Permissions library consider doing something like this:

public function render($request, Exception $exception)
if($exception instanceof \Spatie\Permission\Exceptions\UnauthorizedException && $request->expectsJson()) {
return response()->json([
'status' => $exception->getStatusCode(),
'success' => false,
'error' => [
'code' => null,
'message' => 'User does not have the right permissions'
], $exception->getStatusCode());

return parent::render($request, $exception);

javascript - Vue - Cannot set property of undefined in promise - Stack Overflow

If using ES2015 then use arrow notation to fix these issues.


.then((response) => { //do something that calls this object }

If using ES5 then you need to assign this to an outside variable like so.

var that = this;
.then(function(response) { // do something that calls that }

disk utility - External Hard Drive Won't Mount - Ask Different
I personally ran this a bunch of times to be able to mount my drive to rescue the data. During this rescue process I rebooted my machine many times and everytime the hard drive wouldn't mount on its own. I had to kill the `fsck` processs. I think it finally got resolved when I had finally copied all the data and moved on, that I let the `fsck` process finish on its own.

Nevertheless, the Time Machine backup was corrupt and just reformatted my drive. Now I think things are back to normal.

docker - Dockerized nginx is not starting - Stack Overflow
Docker container runs as long as the command you specify with CMD, ENTRTYPOINT or through the command line is running. In your case the service command finishes right away and the whole container is shut down.

One way to fix this is to start nginx directly from the command line (make sure you don't run it as a daemon).

Fixing Jenkins CLI 'ERROR: anonymous is missing the Overall/Read permission' | Jeff Geerling
Really good tutorial explaining how to deal with / troubleshoot the error message you see when running jenkins-cli.jar tool. Namely, how to authenticate to it.

If you want to authenticate with a file and a username, token combination instead then first, create a token for your user at the user profile page on Jenkins, copy the token value. Then save it as a file with any name: e.g.


for example in this format (separated by the colon):


and then you can add it as an argument in your jenkins cli tool commands like so:

java -jar /opt/jenkins-cli.jar -s "http://localhost:8080" -auth @/path/to/.jenkins_credentials who-am-i

Note that you must prefix the path with the '@' character.

Connecting to a mysql running on a Docker container · Issue #95 · docker-library/mysql
Frankly, this forum page has no consensus on a solution to this issue. Nevertheless, what worked for me on my set up with running MacOS as the Docker host and running a container with: Ubuntu 16.04 and MySQL 5.7 is the following:

1) Within the container: change in /etc/mysql/mysql.conf.d/mysqld.cnf the bind-address option from to
2) Restart MySQL server (note that whenever you start MySQL you must use this command in the Dockerfile:

RUN sed -i -e"s/^bind-address\s*=\s* =" /etc/mysql/mysql.conf.d/mysqld.cnf
RUN find /var/lib/mysql -type f -exec touch {} \; && service mysql start

That is, you must touch the files in /var/lib/mysql and then start the server with service command and not systemctl.

Next, create a user separate from root e.g. dev_1, in MySQL and given them privileges to their '' and '%' hosts. Like this in the Dockerfile:

RUN find /var/lib/mysql -type f -exec touch {} \; && service mysql start && mysql -uroot -proot mysql -e "GRANT ALL ON *.* TO root@'' IDENTIFIED BY 'secret' WITH GRANT OPTION; CREATE USER 'dev_1'@'' IDENTIFIED BY 'secret'; GRANT ALL ON *.* TO 'dev_1'@'' IDENTIFIED BY 'secret' WITH GRANT OPTION; GRANT ALL ON *.* TO 'dev_1'@'%' IDENTIFIED BY 'secret' WITH GRANT OPTION; FLUSH PRIVILEGES;"

Then when you start the container you must publish the port number like so:

docker run -t -d -p 4406:3306 ubuntu_16_04_lemp_php_7_2:latest

If your container stops prematurely, then you might want to add a CMD line in your docker file to run a start.sh script and within that script you might want to add something like this:

# stupid hack to keep container from being stopped
tail -f /dev/null

Finally, to connect to your DB instance on your local MacOS machine with an app like Sequel Pro for example, use the following credentials:

Username: dev_1
Password: <dev_1_password>
Port: 4406

If you don't like to use port 4406, try 3307, 3308, 3309.

vagrant - Ansible variable defined in group_vars/all not found - Stack Overflow
The short of it is: when running ansible command or ansible-playbook command with group_vars directory files the group_vars must be in the same directory as the inventory file itself. So this can either be in the root of your project or inside an actual inventory directory. However, no matter which way you do it the group_vars directory must be beside the main inventory file (e.g. hosts)
