修改文件
mv /etc/mosquitto/aclfile.example /etc/mosquitto/aclfile
user test topic read test/# topic write test/# # This affects access control for clients with no username. topic read $SYS/# # This only affects clients with username "roger". user roger topic foo/bar # This affects all clients. pattern write $SYS/broker/connection/%c/state
配置用户名和密码
groupadd mosquitto useradd -g mosquitto mosquitto
添加启动用户(默认mosquitto用户启动)
groupadd mosquitto useradd -g mosquitto mosquitto
后台启动
mosquitto -c /etc/mosquitto/mosquitto.conf -d
如果报错
查看命令所在目录
find / -name mosquitto
复制命令到对应文件夹
cp mosquitto /usr/local/sbin/
