Smokeping 多机配置

实验的主机系统是Debian,应该只要是Debian系的系统应该都可以.主机系统版本是Raspberrry Pi OS(Debian 10),从机是各种VPS的Debian 10.

首先安装spawn-fcgi和nginx,smokeping,通过apt就可以安装,从机不需要安装nginx,主机Web端口必须可以被访问(不一定是80).

首先理清几个概念:

主机负责布置所有任务,从机通过HTTP POST和主机通信,数据库都在主机.权限是个很麻烦的事情,需要反复折腾,在AMAZ Lightsail Debian 10上没测试成功,最后在Raspbian上实践,问题比较奇怪,暂时不明白.如果出现什么错误,先试试运行:

smokeping --restart

(主机)第一步,安装必要的软件:

apt install smokeping nginx spawn-fcgi

(主机)第二步新建fcgi的映射文件/etc/systemd/system/smokeping-fcgi.service,内容如下:

[Unit]
Description=SmokePing FastCGI Service
After=network.target smokeping.service
Wants=smokeping.service
[Service]
User=root
Group=root
StandardOutput=null
StandardError=syslog
ExecStart=/usr/bin/spawn-fcgi -u smokeping -s /run/smokeping-fcgi.sock -M 755 -n -U www-data -G www-data -- /usr/share/smokeping/smokeping.cgi
Restart=always
[Install]
WantedBy=multi-user.target

(主机)第三步,给Nginx配置反向代理.

location = /smokeping/ {
    fastcgi_pass unix:/run/smokeping-fcgi.sock;
    include /etc/nginx/fastcgi_params;
}
location /smokeping/ {
    alias /usr/share/smokeping/www/;
}

(主机)第四步,按照正常smokeping配置那样,配置目标等等各种参数.

(主机)第五步,设置/var/lib/smokeping的所属为smokeping:www-data,权限为755,设置,最后使用smokeping --restart重启.

(主机)从机配置文件,可以写很多行,这个是Slaves文件.

*** Slaves ***
secrets=/etc/smokeping/smokeping_secrets
+ap-northeast-2
display_name=韩国 首尔
color=0000ff

(主机)而smokeping_secrets是对应密码文件,格式如下:

ap-northeast-2:065538606019

(从机)把从机密码字符串放在/etc/smokeping/secrets,设定权限600,然后新建服务/etc/systemd/system/smokeping.service,内容如下:

[Unit]
Description=Smokeping Service, Network Latency Graphical Viewer
After=network.service
[Service]
Type=forking
Environment=MASTER=18.183.217.124
Environment=CACHEDIR=/usr/local/smokeping/cache/
Environment=SECRET=/etc/smokeping/secrets
Environment=SLAVENAME=eu-west-3
ExecStart=/bin/sh -c "/usr/sbin/smokeping --master-url=http://${MASTER}/smokeping/ --cache-dir=${CACHEDIR} --slave-name=${SLAVENAME} --shared-secret=${SECRET} --logfile=/usr/local/smokeping/slave.log --debug-daemon"
KillSignal=SIGTERM
ExecReload=/bin/sh -c "/usr/sbin/smokeping --master-url=http://${MASTER}/smokeping/ --cache-dir=${CACHEDIR} --slave-name=${SLAVENAME} --shared-secret=${SECRET} --logfile=/usr/local/smokeping/slave.log --debug-daemon --reload"
User=smokeping
Group=smokeping
[Install]
WantedBy=default.target

(从机)新建缓存目录,使能服务,重启服务,就可以等待上线了.

mkdir /usr/local/smokeping/cache -p
chown smokeping:smokeping /usr/local/smokeping -R

批量检查下从机服务是不是正常(pssh):

结果:

实验完毕记得删机,多机费钱啊.
