brew services. Cant start service. get "Bootstrap failed: 5: Input/output error"

try this

brew services restart <mongodb-community@4.4>

I am able to run mongodb through homebrew. I believe this solved my issue:

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist

followed by

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist

I saw this issue with MySQL and the solution was my current profile was not the owner of my homebrew folder.

I had to change it because I have a second profile set up for another work space, but they share the same homebrew path.

I would suggest anyone who sees this error try running

sudo chown -R $(whoami) $(brew --prefix)/*

And then seeing if that will resolve it. Again I didn't have this issue with MongoDB, but I saw this exact error with MySQL when my profile didn't own the brew folder.

To see the real errors, you need to run the service without brew

I had a similar problem, but instead of mongodb, I could not start apache(httpd).

$ brew services start httpd                                                                                                                                                        
Bootstrap failed: 5: Input/output error
Try re-running the command as root for richer errors.
Error: Failure while executing; `/bin/launchctl bootstrap gui/501 
/Users/john/Library/LaunchAgents/homebrew.mxcl.httpd.plist` exited with 
5.
FAIL: 1

Unfortunately brew doesn't show the user what causes this error. At first I tried to use the tips from the answers in this thread, but neither reinstalling apache nor unload -w/load -w helped. I also found nothing in the brew logs. I decided to investigate apache itself. To do this I ran apache without brew:

$ /opt/homebrew/Cellar/httpd/2.4.51/bin/apachectl start
httpd: Syntax error on line 66 of /opt/homebrew/etc/httpd/httpd.conf: Cannot load /opt/homebrew/Cellar/php@5.6/5.6.40_3/lib/httpd/modules/libphp5.so into server: dlopen(/opt/homebrew/Cellar/php@5.6/5.6.40_3/lib/httpd/modules/libphp5.so, 0x000A): tried: '/opt/homebrew/Cellar/php@5.6/5.6.40_3/lib/httpd/modules/libphp5.so' (no such file), '/usr/local/lib/libphp5.so' (no such file), '/usr/lib/libphp5.so' (no such file)
FAIL: 1

Then it was finally clear what was the reason why httpd service was not starting. It turned out that after the php upgrade, the php version had changed and I forgot to write the new php version in the apache configuration file. I quickly fixed this and apache started up.

Try this if you tried to restart your service, but it still doesn't work

1. stop your service

brew services stop mongodb-community

2. restart your macOS
3. start your service again

brew services start mongodb-community

It seems that the mongodb-community is already started. So do restart it instead of starting, by the following command:

brew services restart mongodb-community

I had similar error in regard to postgres.

$ brew services start postgresql
Bootstrap failed: 5: Input/output error
Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/yrk/Library/LaunchAgents/homebrew.mxcl.postgresql.plist` exited with 5.

I've tried restart and it looked promising:

$ brew services restart postgres
Stopping `postgresql`... (might take a while)
==> Successfully stopped `postgresql` (label: homebrew.mxcl.postgresql)
==> Successfully started `postgresql` (label: homebrew.mxcl.postgresql)

But there still was a problem when trying to connect:

 $ psql -d postgres -U apiuser
psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
    Is the server running locally and accepting connections on that socket?

Checking postgres log as mentioned by @mansoor.khan helped, in my case it was: tail /usr/local/var/log/postgres.log.

And the issue was clear:

$ tail /usr/local/var/log/postgres.log

Now the problem is: how to revert to previous version or upgrade old data to new version of postgres DB, but this is for another topic.

I faced a similar problem with postgresql 11 and restarting the service did not help. The issue arose when my MacBook restarted abruptly.

After checking the ports and trying out all the possible solutions, I decided to look into the logs.

tail -n 100 /usr/local/var/log/postgresql@11.log

This gave me the last 100 lines of the log where I found this:

FATAL:  lock file "postmaster.pid" already exists
HINT:  Is another postmaster (PID 479) running in data directory "/usr/local/var/postgresql@11"?

Clearly, the issue was with postmaster.pid so I deleted it:

rm /usr/local/var/postgresql@11/postmaster.pid

Started the postgres service again:

brew services start postgresql@11

and voila! It worked.

run something like launchctl remove homebrew.mxcl.mongodb-community before the load command solved my problem

In my case, another httpd process was running on the Mac. Killed with monitor tool allowed me to start httpd.

I had a similar problem on mysql.

Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/gerd/Library/LaunchAgents/homebrew.mxcl.mysql.plist` exited with 5.

In my case the mysqld miss the osx network connection permission. After restart OSX it appear the network permissions dialog. I granted the permission to msqld and the problem was fixed!

Happened with redis. Realized there was a bind setting in the config, binding the server to an incorrect ip address.

I faced the same problem. This commands helped me

brew uninstall rabbitmq
brew uninstall erlang
brew install rabbitmq
brew services restart rabbitmq
