The mosquitto version 2.0.14 is used here. I compiled it according to the following steps and tested it successfully.
1. Install dependencies
Depend on cjson, compile cjson first:
git clone https://github.com/DaveGamble/cJSON.git
cd cJSON
mkdir build
cd build
cmake ..
make
make instal
2. Compile mosquitto
After downloading and decompressing the mosquitto source code
cd mosquitto-2.0.14
mkdir build
cd build
cmake ../
make
make install
3. Test mosquitto
3.1 Start the service
After compilation, a mosquitto executable file will be generated. Here I am in the directory /home/thera/opensource/mosquitto-2.0.14/build/src.
mosquitto --help #查看启动参数
Follow the prompts to start moquitto
./mosquitto -p 1883 #指定监听1883端口
This shows that mosquitto is running
3.2 Subscription
Find the mosquitto_sub executable file, which is under the /home/thera/opensource/mosquitto-2.0.14/build/client path. Also check the parameters first.
./mosquitto_sub --help
./mosquitto_sub -h 127.0.0.1 -p 1883 -u me -P 123456 -t me/you #-h指定mosquitto地址 -p指定端口 -P 指定密码 -t指定主题
3.3 Release
Find the mosquitto_pub executable file, which is under the /home/thera/opensource/mosquitto-2.0.14/build/client path. Also check the parameters first.
./mosquitto_pub --help
./mosquitto_pub -h 127.0.0.1 -p 1883 -u me -P 123456 -t me/you -m kkkkkk # -m指定消息内容
