Mosquitto部署方法

概述

mosquitto是一款mqtt服务器，常作为内部的数据总线。

oh上部署方法有以下几种部署方式：

按oh的三方库移植
交叉编译二进制包，包含bin/etc/lib，尤其lib里要把依赖库等都包括在内
docker

第一种方案需要分析make文件，比较复杂。目前经过oh社区的支持，已经完成方式2的验证。本文档即描述方式2 二进制包的部署过程，不包括交叉编译的过程（此过程由华为韩晋飞帮助完成）。

部署方法

获取安装包

由社区华为同事提供，分arm32位版本和arm64位版本。

32位版本，下载附件📎ohos_arm_ndk.tar.gz

本地解压后修改mosquitto配置文件

因为ohos内没有vi，编辑配置文件比较麻烦只能在外面改好后推送进去，所以在本地改好后等后面再推送进去。附件配置文件已经修改完毕📎mosquitto.conf，可以直接使用。

mosquitto配置文件在解压后的/etc/mosquitto/mosquitto.conf，主要修改以下配置：

允许匿名访问

如果不设置允许匿名访问的话，就需要ACL认证，ACL可以参考mosquitto基本配置 – 云否归档。

allow_anonymous true

设置启动用户

# When run as root, drop privileges to this user and its primary
# group.
# Set to root to stay as root, but this is not recommended.
# If set to "mosquitto", or left unset, and the "mosquitto" user does not exist
# then it will drop privileges to the "nobody" user instead.
# If run as a non-root user, this setting has no effect.
# Note that on Windows this has no effect and so mosquitto should be started by
# the user you wish it to run as.
user root

设置侦听地址

配置为全地址侦听“0.0.0.0”，否则是127.0.0.1 local mode，只能本地访问。

# =================================================================
# Listeners
# =================================================================

# Listen on a port/ip address combination. By using this variable
# multiple times, mosquitto can listen on more than one port. If
# this variable is used and neither bind_address nor port given,
# then the default listener will not be started.
# The port number to listen on must be given. Optionally, an ip
# address or host name may be supplied as a second argument. In
# this case, mosquitto will attempt to bind the listener to that
# address and so restrict access to the associated network and
# interface. By default, mosquitto will listen on all interfaces.
# Note that for a websockets listener it is not possible to bind to a host
# name.
#
# On systems that support Unix Domain Sockets, it is also possible
# to create a # Unix socket rather than opening a TCP socket. In
# this case, the port number should be set to 0 and a unix socket
# path must be provided, e.g.
# listener 0 /tmp/mosquitto.sock
#
# listener port-number [ip address/host name/unix socket path]
#listener
listener 1883 0.0.0.0

上传配置文件到开发板etc下

D:>hdc file send mosquitto.conf /etc/

上传安装包到开发板

注意oh默认没有写文件权限，先本地进入os加写文件权限

D:>hdc shell
#mount -o rw,remount -t auto /

然后再上传到开发板（注意：由于os是3.2，所以工具套件也建议用3.2sdk）

>hdc file send mosquitto_bin.tar.gz /data/
FileTransfer finish, Size:40464, File count = 1, time:23ms rate:1759.30kB/s

Tip:

最好开两个CMD窗口，一个负责传文件，一个作为os内的主要操作。因为ohos内没有vi，没法编辑配置文件，所以只能在外面改好后推送进去。另外服务启动要配置环境变量，目前还没有找到类似bachrc的配置方法，所以最好有一个持久的hdc会话。

解压并复制执行文件到相应目录

#cd /data/
#tar -zxvf mosquitto_bin.tar.gz
#cd mosquitto_bin/sbin
#cp mosquitto /bin

设置LD_LIBRARY_PATH环境变量

注意：需要对应到解压后的lib目录，下面是64位包对应的目录位置。

#export LD_LIBRARY_PATH=/data/mosquitto_bin/lib:$LD_LIBRARY_PATH

32bit包，如果在data目录解压后，export路径如下

#export LD_LIBRARY_PATH=/data/ohos_arm_ndk/lib:$LD_LIBRARY_PATH

启动服务

以conosole方式，带参数启动mosquitto，可方便查看连接等日志信息
