MQTT 在 mac 上搭建

http://blog.csdn.net/YAJUN0601/article/details/41981399

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receive

A CA file has been bootstrapped using certificates from the system

keychain. To add additional certificates, place .pem files in

/usr/local/etc/openssl/certs

and run

/usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Mac OS X already provides this software and installing another version in

parallel can cause all kinds of trouble.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences of this for you. If you build your

own software and it requires this formula, you'll need to add to your

build variables:

LDFLAGS:  -L/usr/local/opt/openssl/lib

CPPFLAGS: -I/usr/local/opt/openssl/include

==> Caveats

mosquitto has been installed with a default configuration file.

You can make changes to the configuration by editing:

/usr/local/etc/mosquitto/mosquitto.conf

Python client bindings can be installed from the Python Package Index:

pip install mosquitto

Javascript client has been removed, see Eclipse Paho for an alternative.

To have launchd start mosquitto at login:

ln -sfv /usr/local/opt/mosquitto/*.plist ~/Library/LaunchAgents

Then to load mosquitto now:

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mosquitto.plist

Or, if you don't want/need launchctl, you can just run:

mosquitto -c /usr/local/etc/mosquitto/mosquitto.conf
