在CentOS7上部署SmokePing

缘起

公司某一业务网站在晚上有个别用户反应PING值不稳定的情况，由于影响到业务运行，故搭建SmokePing监控业务运行情况，收集数据以便分析。

安装依赖

进行时间同步

1 2	`yum install ntp -y ntpdate times.aliyun.com`

接下来安装开发依赖包

1	`yum groupinstall "Compatibility libraries" "Base" "Development tools" -y`

有些软件在epel上，首先安装epel

1	`yum install epel-release -y`

安装smokeping所依赖的包，因为官方推荐使用apache，这里我们使用apache。nginx也是可以的，但是需要自行配置FCGI。

yum install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-IO-Socket-SSL perl-Socket6 perl-Time-HiRes perl-ExtUtils-MakeMaker rrdtool rrdtool-perl curl  httpd httpd-devel gcc make  wget libxml2-devel libpng-devel glib pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel perl-CGI-SpeedyCGI perl-Sys-Syslog popt-devel libidn-devel fping -y

安装SmokePing

wget --no-check-certificate http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.8.tar.gz   #官网证书用的是Let's Encrypt，有些网络环境无法下载，需要添加 --no-check-certificate 参数
tar xvf smokeping-2.6.8.tar.gz
cd smokeping-2.6.8
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
./configure --prefix=/usr/local/smokeping
 /usr/bin/gmake install
 /usr/bin/gmake install    #第一次安装会出错，需要安装两次

修改SmokePing配置

cd /usr/local/smokeping/
mkdir cache data var   #需要自行创建这几个目录
touch /var/log/smokeping.log   #创建日志文件
chown apache:apache cache data var   #阿帕奇权限配置
chown apache:apache /var/log/smokeping.log   #阿帕奇权限配置
chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist  #必须给600权限
cd /usr/local/smokeping/htdocs
mv smokeping.fcgi.dist smokeping.fcgi
cd /usr/local/smokeping/etc
mv config.dist config

配置Apache配置

1	`vim /etc/httpd/conf/httpd.conf`

将 <Directory “/var/www/html”> 改成 <Directory “/usr/local/smokeping”>

建立一个SmokePing的网站配置
/etc/httpd/conf.d/somekping.conf
写入以下内容

Alias /cache "/usr/local/smokeping/cache/"
Alias /cropper "/usr/local/smokeping/htdocs/cropper/"
Alias /smokeping "/usr/local/smokeping/htdocs/smokeping.fcgi"
<Directory "/usr/local/smokeping">
AllowOverride None
Options All
AddHandler cgi-script .fcgi .cgi
Order allow,deny 
Allow from all 
DirectoryIndex smokeping.fcgi
</Directory>

之后重启Apache服务器
systemctl restart httpd
访问 http://IP/smokeping

至此，SmokePing搭建完毕，不过现在还是不能使用，我们还需要一些配置。

监控配置

修改SmokePing配置文件
vim /usr/local/smokeping/etc/config
把 cgiurl = http://some.url/smokeping.cgi 修改为 cgiurl = http://10.1.30.184/smokeping.cgi
10.1.30.184为SmokePing服务器IP，根据实际情况进行修改
修改监控频率

1 2	`* Database * step = 600 改为 step = 30`

之后删除默认的test数据，数据在配置文件的末尾，从 +Test开始全部删除

添加监控配置

+ Other
menu = 网络监控
title = 监控统计
++ PhiWeb
menu = PhiWeb网络状态
title = PhiWeb网络监控
+++ Master
menu = Phi主控
title = Phi主控
alerts = someloss
host = 12.34.56.78
+++ SlaveServer02
menu = PhiServer02
title = PhiServer02
alerts = someloss
host = 12.34.56.78
+++ SlaveServer03
menu = PhiServer03
title = PhiServer02
alerts = someloss
host = 12.34.56.78

+是第一层，++是第二层，+++ 是第三层,根据实际情况修改

启动SmokePing

1	`/usr/local/smokeping/bin/smokeping`

现在查看网页会发现乱码

修改配置文件，指定字符集

1	`vim /usr/local/smokeping/etc/config`

在Presentation下添加charset = utf-8
安装字体包

1	`yum -y install wqy-zenhei-fonts`

修改 Graphs.pm

1	`vim /usr/local/smokeping/lib/Smokeping/Graphs.pm`

在148行附近寻找，增加这一行 ‘–font TITLE:20””‘,

SmokePing有个问题，无法重载配置，只能手动Kill掉进程再启动

[root@localhost etc]# /usr/local/smokeping/bin/smokeping
Note: logging to syslog as local0/info.
ERROR: I Quit! Another copy of /usr/local/smokeping/bin/smokeping (87268) seems to be running.
       Check /usr/local/smokeping/var/smokeping.pid
[root@localhost etc]# kill 87268
[root@localhost etc]# /usr/local/smokeping/bin/smokeping
Note: logging to syslog as local0/info.
Daemonizing /usr/local/smokeping/bin/smokeping ...

重启SmokePing后，可以正常显示中文了
