smokeping 可以用来很好的检测网络状态和稳定性

1、调整防火墙的设置
[root@C65-A1 ~]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter [OK]
iptables: Flushing firewall rules: [OK]
iptables: Unloading modules: [OK]
[root@C65-A1 ~]# chkconfig iptables off
[root@C65-A1 ~]# getenforce
Enforcing
[root@C65-A1 ~]# setenforce 0
[root@C65-A1 ~]# vim /etc/sysconfig/selinux
将“SELINUX=enforcing”改为“SELINUX=disabled”

2、修改 yum 安装源

[root@C65-A1 ~]# vim /etc/sysconfig/selinux
[root@C65-A1 ~]# rpm -Uvh http://apt.sw.be/RedHat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
Retrieving http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
warning: /var/tmp/rpm-tmp.7A2TOZ: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY
Preparing… ########################################### [100%]
1:rpmforge-release ########################################### [100%]

3、安装 rrdtool 与依赖库

[root@C65-A1 ~]# yum -y install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6 perl-CGI-SpeedyCGI perl-FCGI perl-CGI-SpeedCGI perl-Time-HiRes perl-ExtUtils-MakeMaker perl-RRD-Simple rrdtool rrdtool-perl curl fping echoping 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 mod_fastcgi

4、安装 smokeping

123456 [root@C65-A1 ~]# tar zxvf smokeping-2.6.9.tar.gz
[root@C65-A1 ~]# cd smokeping-2.6.9
出现问题是因为需要安装 perl 的模块，所以运行下面内容即可
[root@C65-A1 ~]# ./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
[root@C65-A1 ~]# ./configure –prefix=/usr/local/smokeping
[root@C65-A1 ~]# /usr/bin/gmake install

5、配置 smokeping
[root@C65-A1 smokeping-2.6.9]# cd /usr/local/smokeping/
[root@C65-A1 smokeping]# mkdir -p var cache data
[root@C65-A1 smokeping]# touch /var/log/smokeping.log
[root@C65-A1 smokeping]# chown apache:apache var cache data
[root@C65-A1 smokeping]# chown apache:apache /var/log/smokeping.log
[root@C65-A1 smokeping]# ls
bin cache data etc htdocs lib share thirdparty var
[root@C65-A1 smokeping]# cd /usr/local/smokeping/htdocs/
[root@C65-A1 htdocs]# ls
cropper smokeping.fcgi.dist
[root@C65-A1 htdocs]# cp -p smokeping.fcgi.dist /tmp/
[root@C65-A1 htdocs]# mv smokeping.fcgi.dist smokeping.fcgi
[root@C65-A1 htdocs]# cd /usr/local/smokeping/etc/
[root@C65-A1 etc]# ls
basepage.html.dist examples smokeping_secrets.dist
config.dist smokemail.dist tmail.dist
[root@C65-A1 etc]# cp -p config.dist /tmp/
[root@C65-A1 etc]# mv config.dist config
[root@C65-A1 etc]# vim config

a. 将“cgiurl = http://some.url/smokeping.cgi”修改为“cgiurl = http://192.168.1.14/smokeping.cgi”
b. 将 *** Database *** 中的“step = 300”修改为 ”step = 60″, 每分钟取样一次
step = 300
pings = 20
[root@C65-A1 etc]# chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
备注：修改密码文件权限

6、调整 apache 的配置
123456789101112131415161718192021222324 [root@C65-A1 etc]# vim /etc/httpd/conf/httpd.conf
添加如下信息：
###set for smokeping###
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
AllowOverride AuthConfig
Order allow,deny
Allow from all
AuthName “Smokeping”
AuthType Basic
AuthUserFile /usr/local/smokeping/htdocs/htpasswd
Require valid-user
DirectoryIndex smokeping.fcgi
</Directory>
[root@C65-A1 etc]# cd /usr/local/smokeping/htdocs/
[root@C65-A1 htdocs]# htpasswd -c /usr/local/smokeping/htdocs/htpasswd admin
New password:
Re-type new password:
Adding password for user admin

7、设置 smokeping 开机启动
[root@C65-A1 etc]# echo “/usr/local/smokeping/bin/smokeping –logfile=/var/log/smokeping.log 2>&1 &” >> /etc/rc.local

8、添加 smokeping 开机脚本

在 /etc/init.d 目录下新建 smokeing 的文件，内容如下：
#!/bin/bash
#
# chkconfig: 2345 80 05
# Description: Smokeping init.d script
# Hacked by : jeff kang – http://www.jffnms.net
# Get function from functions library
. /etc/init.d/functions
# Start the service Smokeping
start() {
echo -n “Starting Smokeping: “
/usr/local/smokeping/bin/smokeping >/dev/null 2>&1
### Create the lock file ###
touch /var/lock/subsys/smokeping
success $”Smokeping startup”
echo
}
# Restart the service Smokeping
stop() {
echo -n “Stopping Smokeping: “
kill -9 `ps ax | grep ” /usr/local/smokeping/bin/smokeping” | grep -v grep | awk ‘{print $1}’` >/dev/null 2>&1
### Now, delete the lock file ###
rm -f /var/lock/subsys/smokeping
success $”Smokeping shutdown”
echo
}
### main logic ###
case “$1” in
start)
start
;;
stop)
stop
;;
status)
status Smokeping
;;
restart|reload|condrestart)
stop
start
;;
*)
echo $”Usage: $0 {start|stop|restart|reload|status}”
exit 1
esac
exit 0

9、开启 smokeping 服务
[root@C65-A1 init.d]# /etc/init.d/smokeping start
Starting Smokeping: [OK]
[root@C65-A1 init.d]# ps -ef | grep smokeping
root 9670 1 0 17:42 ? 00:00:00 /usr/local/smokeping/bin/smokeping [FPing]
root 9673 1264 0 17:42 pts/0 00:00:00 grep smokeping
然后我们可以通过 http://192.168.1.144/smokeping.cgi，输入用户名和密码进入 smokeping 了

10、smokeping 里面开启中文支持并安装中文字体
[root@C65-A1 htdocs]# vim /usr/local/smokeping/etc/config
如果需要在网页里展示中文，修改 /usr/local/smokeping/etc/config 文件
*** Presentation ***
charset = utf-8 // 注：在这里添加
[root@C65-A1 htdocs]# yum -y install wqy*

11、添加监控信息，重启服务，使配置生效
[root@C65-A1 htdocs]# vim /usr/local/smokeping/etc/config
[root@C65-A1 htdocs]# /etc/init.d/smokeping stop
Stopping Smokeping: [OK]
[root@C65-A1 htdocs]# /etc/init.d/smokeping start
Starting Smokeping: [OK]
[root@C65-A1 htdocs]# ps -ef | grep smokeping
root 9861 1 0 18:04 ? 00:00:00 /usr/local/smokeping/bin/smokeping [FPing]
root 9864 1442 0 18:04 pts/1 00:00:00 grep smokeping

12、其它资料
检查 smokeping 的配置文件
[root@C65-A1 htdocs]# /usr/local/smokeping/bin/smokeping –check
Configuration file ‘/usr/local/smokeping/bin/../etc/config’ syntax OK.
[root@C65-A1 htdocs]# /usr/local/smokeping/bin/smokeping –help
说明：
+ Gansu // 注意，这里加号后面的必须是英文，不能是中文
menu = 甘肃
title = 甘肃
++ Daliang // 同样，这里‘++’后面的必须是英文，+ 和 ++ 后面的内容是不会被现实的，只是起一个命名的作用。
menu = 大梁
title = 大梁:10.138.1.11
host = 10.138.1.11
alerts = someloss
一级、二级、三级目录的结构：
+ yiji
menu = 一级
title = 一级
++ erji
menu = 二级
title = 二级
+++ sanji
menu = sanji
title =sanji:10.138.16.54
host = 10.138.16.54
alerts = someloss
title 代表的是右边图片显示的标题，memu 代表的是左边的菜单
