RabbitMQ Server – Issue with High Sierra – Mac OS

macOS RabbitMq

After updating to High Sierra, I faced issues with starting rabbitmq-server.  The command gave the following error:

RabbitMQ 3.6.3. Copyright (C) 2007-2016 Pivotal Software, Inc.
## ## Licensed under the MPL. See http://www.rabbitmq.com/
## ##
########## Logs: /usr/local/var/log/rabbitmq/rabbit@localhost.log
###### ## /usr/local/var/log/rabbitmq/rabbit@localhost-sasl.log
##########
Starting broker...
completed with 10 plugins.
Assertion failed: (ctx), function digest_update, file /BuildRoot/Library/Caches/com.apple.xbs/Sources/boringssl/boringssl-109.20.5/apple/crypto/digests.c, line 49.
/usr/local/sbin/rabbitmq-server: line 236: 2681 Abort trap: 6 start_rabbitmq_server "$@"

I narrowed down the issue to a problem with Home Brew. I had installed rabbitmq via HomeBrew a while back and with the changes in the operating system rabbitmq was failing to start.

Running the following command gave the below error message:

$ brew update
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Error: /usr/local is not writable. You should change the ownership
and permissions of /usr/local back to your user account:
sudo chown -R $(whoami) /usr/local

How to fix RabbitMQ Server – Issue with High Sierra

  1. Reinstall Home Brew using the following command:
    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  2. Then run:
    brew update
  3. Then run:
    brew reinstall rabbitmq
  4. Once done you must  be able to run rabbitmq-server to get the server up and running.

How to Rename Column in Mysql

rename column mysql

To Rename a Column in Mysql we need to use the ALTER query with CHANGE COLUMN statement. The standard version of this query is:

ALTER [ONLINE | OFFLINE] [IGNORE] TABLE tbl_name
CHANGE [COLUMN] old_col_name new_col_name column_definition
[FIRST|AFTER col_name]

For Example:

ALTER TABLE City CHANGE CityId cityId varchar(25) NOT NULL;

Note: You will need to mention every constraint of the original column as defaults are assumed otherwise.

JavaScript Date Format YYYY-MM-DD

Here is a simple function that takes the input of JS Date and returns a string of format YYYY-MM-DD:

var getDateFromDateTime = function(date) {
date = new Date(date); //Using this we can convert any date format to JS Date
var mm = date.getMonth() + 1; // getMonth() is zero-based
var dd = date.getDate();
if(mm<10){ mm="0"+mm; } if(dd<10){ dd="0"+dd; } return [date.getFullYear(), mm, dd].join('-'); // padding };
