오픈소스 MQTT Broker인 Mosquitto를 설치하자.
의존성 패키지 설치
# yum install gcc*
# yum install openssl openssl-devel
# yum install pcre pcre-devel
# yum install zlib zlib-devel
# yum install glibc glibc-devel
CentOS는 기본적으로 OpenSSL을 탑재하고 있다.
# openssl version
OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
하지만 최신 OpenSSL로 재설치하자.
# cd /usr/local/src
# wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
# tar zxvf openssl-1.0.1c.tar.gz
# cp -Rf openssl-1.0.1c /usr/local/openssl
# cd ../openssl/
# export LDFLAGS=-L/usr/local/lib
# export CPPFLAGS=-I/usr/local/include
# make clean
# ./config --prefix=/usr --openssldir=/usr/local/openssl shared threads zlib
# make
# make test
# make install
# make clean
# unset LDFLAGS
# unset CPPFLAGS
# vi /etc/ld.so.conf
# openssl lib 폴더 경로 추가
include /usr/local/openssl/lib
# /sbin/ldconfig
OpenSSL 버전확인

자. Mosquitto를 설치하자.
우선 mosquito 계정을 만들자
# useradd mosquitto
# groupadd mosquitto
소스를 다운받아 설치하자.
# cd /usr/local/src
# wget http://mosquitto.org/files/source/mosquitto-1.1.2.tar.gz
# tar zxvf mosquitto-1.1.2.tar.gz
# cp -Rf mosquitto-1.1.2 /usr/local/mosquitto
# cd ../mosquitto
# make && make install
# vi /etc/ld.so.conf
include /usr/local/mosquitto/lib
# /sbin/ldconfig
# ln -s /usr/local/mosquitto/lib/libmosquitto.so.1 /usr/lib/libmosquitto.so.1
MOSQUITTO_HOME 셋팅
# vi /etc/profile
MOSQUITTO_HOME=/usr/local/mosquitto
export MOSQUITTO_HOME
PATH=$PATH:$MOSQUITTO_HOME/src
export PATH
# source /etc/profile
mosquitto 포트 개방 (1883)
# iptables -I INPUT -m tcp -p tcp --dport 1883 -j ACCEPT
# /sbin/service iptables save
# /sbin/service iptables restart
구동하기 (http://mosquitto.org/man/mosquitto-8.html)
# mosquitto -c /usr/local/mosquitto/mosquitto.conf -d > /log/mosquitto/mosquitto.log 2>&1
잘 구동되었나 확인
# tail -f /log/mosquitto/mosquitto.log
1361175067: mosquitto version 1.1.2 (build date 2013-02-18 16:12:55+0900) starting
1361175067: Config loaded from mosquitto.conf.
1361175067: Opening ipv6 listen socket on port 1883.
1361175067: Opening ipv4 listen socket on port 1883.
테스트를 해보자.
한쪽에는 sub를 실행해놓구
# mosquitto_sub -h 192.168.0.201 -t /test/1
다른쪽에는 pub를 보내면
# mosquitto_pub -h 192.168.0.201 -t /test/1 -m "testtest"
sub쪽에 메시지가 잘 도착할 것이다.
