（二）安装
1，关闭selinux

[[email protected] tmp]# setenforce 0
[[email protected] tmp]# vim /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
[[email protected] tmp]# source  /etc/selinux/config 

2，安装相关依赖的包
[[email protected] tmp]# yum install -y rrdtool wqy* fping gcc echoping curl bind-utils httpd httpd-devel perl perl-FCGI perl-CGI perl-CGI-SpeedyCGI 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 perl-RadiusPerl perl-Time-HiRes perl-RRD-Simple libxml2-devel libpng-devel glib pango pango-devel freetype freetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel mod_fastcgi

4，编译安装smokeping

#请注意在configure前需要先build相应的perl模块，否则有报错。
[[email protected] tmp]# ls
ks-script-HudzSv  smokeping-2.6.11.tar.gz  yum.log
[[email protected] tmp]# tar xf smokeping-2.6.11.tar.gz 
[[email protected] tmp]# cd smokeping-2.6.11
[[email protected] smokeping-2.6.11]# ./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
[[email protected] smokeping-2.6.11]# ./configure --prefix=/usr/local/smokeping
[[email protected] smokeping-2.6.11]# gmake install

5,配置smokeping
1，创建相应的目录并赋予权限

[[email protected] smokeping-2.6.11]# cd /usr/local/smokeping/
[[email protected] smokeping]# ll
total 0
drwxr-xr-x. 2 root root  75 Jan 18 19:35 bin
drwxr-xr-x. 3 root root 137 Jan 18 19:35 etc
drwxr-xr-x. 3 root root  48 Jan 18 19:35 htdocs
drwxr-xr-x. 3 root root 100 Jan 18 19:35 lib
drwxr-xr-x. 3 root root  17 Jan 18 19:35 share
drwxr-xr-x. 6 root root  67 Jan 18 19:34 thirdparty
[[email protected] smokeping]# mkdir var cache data
[[email protected] smokeping]# chown apache.apache var/ cache/ data/
[[email protected] smokeping]# ll
total 0
drwxr-xr-x. 2 root   root    75 Jan 18 19:35 bin
drwxr-xr-x. 2 apache apache   6 Jan 18 19:48 cache
drwxr-xr-x. 2 apache apache   6 Jan 18 19:48 data
drwxr-xr-x. 3 root   root   137 Jan 18 19:35 etc
drwxr-xr-x. 3 root   root    48 Jan 18 19:35 htdocs
drwxr-xr-x. 3 root   root   100 Jan 18 19:35 lib
drwxr-xr-x. 3 root   root    17 Jan 18 19:35 share
drwxr-xr-x. 6 root   root    67 Jan 18 19:34 thirdparty
drwxr-xr-x. 2 apache apache   6 Jan 18 19:48 var

2，备份fcgi文件与config文件

[[email protected] smokeping]# cp /usr/local/smokeping/htdocs/smokeping.fcgi.dist  /usr/local/smokeping/htdocs/smokeping.fcgi
[[email protected] smokeping]# cp /usr/local/smokeping/etc/config.dist /usr/local/smokeping/etc/config

3，修改config文件，把cgiurl = http://some.url/smokeping.cgi中的some.url换成你的IP地址

[[email protected] smokeping]# sed -i ‘s|some.url|172.20.66.111|g‘ /usr/local/smokeping/etc/config
[[email protected] smokeping]# vim etc/config

*** General ***

owner    = Peter Random
contact  = [email protected]
mailhost = my.mail.host
sendmail = /usr/sbin/sendmail
# NOTE: do not put the Image Cache below cgi-bin
# since all files under cgi-bin will be executed ... this is not
# good for images.
imgcache = /usr/local/smokeping/cache
imgurl   = cache
datadir  = /usr/local/smokeping/data
piddir  = /usr/local/smokeping/var
cgiurl   = http://172.20.66.111/smokeping.cgi

4，Alerts和database配置

*** Alerts ***
to = [email protected]
from = [email protected]

+someloss
type = loss
# in percent
pattern = >0%,*12*,>0%,*12*,>0%
comment = loss 3 times  in a row

#新增rtt监测机制
+rttdetect
type = rtt
# in milliseconds
pattern = <55,<55,<55,>55,>55,>55
comment = 每次发出60个包，连续3次轮询检查延时超过55毫秒

*** Database ***
######默认300秒ping20次，修改为120秒ping30次
step     = 120
pings    = 30

5，presentation配置，添加utf-8字符集和在detail部分，修改历史数据展示的时间

*** Presentation ***
###添加UTF-8中文字符集
charset = utf-8

template = /usr/local/smokeping/etc/basepage.html.dist

+ charts

menu = Charts
title = The most interesting destinations

++ stddev
sorter = StdDev(entries=>4)
title = Top Standard Deviation
menu = Std Deviation
format = Standard Deviation %f

++ max
sorter = Max(entries=>5)
title = Top Max Roundtrip Time
menu = by Max
format = Max Roundtrip Time %f seconds

++ loss
sorter = Loss(entries=>5)
title = Top Packet Loss
menu = Loss
format = Packets Lost %f

++ median
sorter = Median(entries=>5)
title = Top Median Roundtrip Time

width = 600
height = 50
range = 10h

+ detail

width = 600
height = 200
unison_tolerance = 2

"Last 10 Minutes" 10m
"Last 30 Minutes" 30m
"Last 4 Hours" 4h  
"Last 12 Hours" 12h
"Last 1 Days" 24h
"Last 3 Days" 3d
"Last 1 Weeks" 7d
"Last 1 Mouths" 30d
"Last Half years" 180d
"Last 1 years" 365d
#"Last 3 Hours"    3h
#"Last 30 Hours"   30h
#"Last 10 Days"    10d
#"Last 400 Days"   400d

6，修改账号文件权限
[[email protected] smokeping]# chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
7，创建登录账号和密码

[[email protected] smokeping]# htpasswd -c /usr/local/smokeping/htdocs/htpasswd admin
New password: 
Re-type new password: 
Adding password for user admin
[[email protected] smokeping]# 

7，设置httpd的访问路径

[[email protected] smokeping]# vim /etc/httpd/conf/httpd.conf
DocumentRoot "/var/www/html"

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> 

8，关闭防火墙

[[email protected] smokeping]# service firewalld stop
[[email protected] smokeping]# systemctl stop iptables.service

9.设置开机启动
[[email protected] smokeping]# echo "/usr/local/smokeping/bin/smokeping &">> /etc/rc.local
