SmokePing 部署实践

1 通过 yum 安装依赖的库以及环境

yum install rrdtool wqy* fping curl bind-utils httpd httpd-devel \ perl perl-FCGI perl-CGI perl-CGI-SpeedyCGI perl-libwww-perl perl-Socket6 perl-Net-Telnet perl-Net-OpenSSH perl-Net-DNS perl-LDAP perl-IO-Socket-SSL perl-ExtUtils-MakeMaker rrdtool-perl perl-Sys-Syslog

2 编译安装 smokeping

cd /usr/local/src/
wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.11.tar.gz
tar xvf smokeping-2.6..tar.gz
cd smokeping-2.6.
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
./configure --prefix=/usr/local/smokeping
gmake install

3 配置 smokeping 相关文件目录

cd /usr/local/smokeping/
mkdir cache data var
touch /var/log/smokeping.log
chown apache.apache cache/ data/ var/ /var/log/smokeping.log
cd /usr/local/smokeping/htdocs/
cp smokeping.fcgi.dist smokeping.fcgi
cp /usr/local/smokeping/etc/config.dist /usr/local/smokeping/etc/config
vim /usr/local/smokeping/etc/config

# 修改 /usr/local/smokeping/etc/config 文件

# 修改 cgiurl
sed -i 's#some.url#192.168.56.11#' /usr/local/smokeping/etc/config

# 默认检测时间  秒修改  秒
sed -i 's#300#60#g' /usr/local/smokeping/etc/config        

# 默认  秒 ping  次，修改为  秒 ping  次
sed -i 's#pings    = 20#pings    = 60#' /usr/local/smokeping/etc/config

# 在 presentation 后添加 utf- 中文字符集
vim /usr/local/smokeping/etc/config               

*** Presentation ***

charset = utf-

# 修改密码文件权限
chmod  /usr/local/smokeping/etc/smokeping_secrets.dist

4 配置 apache

4.1 设置登录密码认证

htpasswd -c /usr/local/smokeping/htdocs/htpasswd jamin

4.2 修改 apache 配置文件，配置 smokeping 站点目录

vim /etc/httpd/conf/httpd.conf
DocumentRoot "/var/www/html" 下添加如下内容

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
    AuthName "Smokeping"
    AuthType Basic
    AuthUserFile /usr/local/smokeping/htdocs/htpasswd
    Require valid-user
    DirectoryIndex smokeping.fcgi
</Directory>

5 启动服务以及访问 smokeping

systemctl start httpd
/usr/local/smokeping/bin/smokeping

访问 URL:
http://服务器ip/smokeping

6  smokeping 使用

6.1 添加需要监控的节点

注意事项：

1 在 /usr/local/smokeping/etc/config 中添加
2 smokeping 就这点不好，添加节点不能在前台 Web 页面添加，一定要在后台的配置文件中添加
3 修改 /usr/local/smokeping/etc/config 后，必须重启 smokeping 程序，配置才会生效 
4 smokeping 会根据配置文件 config 在 /usr/local/smokeping/data 之下添加文件夹及子文件夹
5 用 VMware Workstation 的虚拟机测试有一点好处，虚拟网卡可以设置出入的丢包率，适合 smokeping 做丢包测试，经过测试 smokeping 检测出的丢包率与 VMware Workstation 虚拟网卡设置的丢包率基本相同，也就是说 smokeping 能够反应网络的真实状况

添加监控节点示例：注意 + 是第一层，++ 是第二层，+++ 是第三层

报错

1 .fping yum安装没有正常安装上去，需手动下载fping安装包，源码安装，在配置文件中修改fping命令的路径

2.  安装./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty 时安装不上，可从另外能成功安装的一台上tar 打包文件夹thirdparty, 再传到这台解压缩到相应目录。

遇到部分IP不能直接进行ping操作，可用tcping命令结合smokeping , 必须在Centos 6 上部署。

先安装 tcping 命令

To install tcptraceroute on CentOS/REHL, first set up RepoForge on your system, and then:

$ sudo yum install tcptraceroute

Finally, download tcpping from the web.

$ cd /usr/bin
$ sudo wget http://www.vdberg.org/~richard/tcpping
$ sudo chmod  tcpping

To measure network latency by using tcpping, simply run it as follows.

$ tcpping www.cnn.com
seq : tcp response from 157.166.240.13 [open] 82.544 ms
seq : tcp response from 157.166.241.10 [open] 80.771 ms
seq : tcp response from 157.166.241.11 [open] 80.838 ms
seq : tcp response from 157.166.241.10 [open] 80.145 ms
seq : tcp response from 157.166.240.11 [open] 86.253 ms
