Mosquitto安装与部署

版本说明：

Mosquitto版本：v2.0.10

libwebsockets版本：v3.0.1(用于支持websockets)

mosquitto-go-auth(Mosquitto plugin)：v1.50(提供权限认证)

1.编译前准备

因为我们准备本机编译源码包，所以要提前安装gcc

yum -y install gcc-c++ cmake

还有一些三方依赖

yum install openssl-devel

yum install libuuid-devel

yum install c-ares-devel

yum install uuid-devel

yum install libwebsockets-devel.x86_64

yum install libwebsockets.x86_64

2.下载Mosquitto源码

从官网下载Mosquitto源码压缩包, 或者从github上下载也是可以的, 我这里使用的版本2.0.10

3.解压并安装Mosquitto

Mosquitto默认是不支持websockets的，要在编译前修改config.mk，WITH_WEBSOCKETS:=yes，把no改为yes

执行make，make install；

如果遇到fatal error: cjson/cJSON.h: No such file or directory报错，那么要提前安装cJSON(这里cJSON的安装，yum和apt不一定能找到，可以直接从github上下载源码压缩包，然后解压，进入目录，并make，make install), 这是当前版本的bug，后期应该会修复吧;

安装完成之后，添加名称为mosquitto的用户，并将相关文件夹授权给mosquitto用户

sudo groupadd mosquitto

sudo useradd -s /sbin/nologin mosquitto -g mosquitto -d /var/lib/mosquitto

sudo mkdir -p /var/log/mosquitto/ /var/lib/mosquitto/

sudo chown -R mosquitto:mosquitto /var/log/mosquitto/

sudo chown -R mosquitto:mosquitto /var/lib/mosquitto/

创建/etc/systemd/system/mosquitto.service文件

[Unit]

Description=Mosquitto MQTT v3.1/v3.1.1 server

Wants=network.target

Documentation=http://mosquitto.org/documentation/

[Service]

Type=simple

User=mosquitto

Group=mosquitto

ExecStart=/usr/local/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf

Restart=on-failure

SyslogIdentifier=Mosquitto

[Install]

WantedBy=multi-user.target

设置开机启动

sudo systemctl enable mosquitto

4.解压并安装Mosquitto auth插件

我安装的是mosquitto-go-auth插件，因为是go语言写的插件，所以要提前安装golang，建议同时设置go的代理go env -w GOPROXY=https://mirrors.aliyun.com/goproxy，编译后得到go-auth.so插件

5.配置mosquitto

修改/etc/mosquitto/mosquitto.conf

per_listener_settings true

include_dir /etc/mosquitto/conf

persistence true

persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log

#password_file /etc/mosquitto/pwfile

#acl_file /etc/mosquitto/aclfile

log_timestamp true

log_timestamp_format %Y-%m-%dT%H:%M:%S

log_type all

创建/etc/mosquitto/conf文件夹，并将go-auth.so插件移入，创建go-auth-mqtt.conf配置文件，go-auth-websockets.conf配置文件，分别对应mqtt协议，websockets协议
