Mysql配合PHP程序存储一些变量数据并对变量数据进行调用如主机名、主机ip、snmp团体名、端口号、模板信息等变量。3. snmp抓到数据不是存储在mysql中而是存在rrdtool生成的rrd文件中在cacti根目录的rra文件夹下。rrdtool对数据的更新和存储就是对rrd文件的处理rrd文件是大小固定的档案文件Round Robin Archive它能够存储的数据笔数在创建时就已经定义。cacti的工作流程可以用下图表示cacti的安装配置本地yum[rootcacti ~]# vim /etc/yum.repos.d/rhel-debuginfo.repo[rhel-Server]nameRed Hat Enterprise Linux Serverbaseurlfile:///mnt/cdrom/Serverenabled1gpgcheck1gpgkeyfile:///mnt/cdrom/RPM-GPG-KEY-redhat-release[rootcacti ~]# mkdir /mnt/cdrom[rootcacti ~]# mount /dev/cdrom/mnt/cdrom/mount: block device /dev/cdrom iswrite-protected, mounting read-only[rootcacti ~]# yum install httpd php php-mysql php-snmp mysql-serverperl-DBD-MySQL php-pdo net-snmp net-snmp-libs net-snmp-utils net-snmp-develruby –y[rootcacti ~]# service httpd start[rootcacti ~]# chkconfig httpd on[rootcacti ~]# service mysqld start[rootcacti ~]# chkconfig mysqld on[rootcacti ~]# mysqladmin -u root -ppassword 123[rootcacti ~]# mysql -u root –pmysql CREATE DATABASE cacti;mysql grant all privileges on cacti.* to cactilocalhostidentified by cacti;mysql grant all privileges on cacti.* to cacti127.0.0.1identified by cacti;mysql grant all privileges on cacti.* tocacti192.168.2.0 identified by cacti;mysql flush privileges;mysql quit上传需要用的软件软件资料下载地址http://down.51cto.com/data/994246cacti-0.8.7g.tar.gz cacti的主程序cacti-plugin-0.8.7g-PA-v2.8.tar.gz 插件管理器feition.tar.bz2 用于飞信报警的程序monitor-latest.tgz 实现只管监测的插件sendMsg.zip 发送MSN消息的应用settings-latest.tgz 增强功能的插件例如发送电子邮件thold-latest.tgz 实现达到预值告警的插件[rootcacti software]# yum localinstallrrdtool* --nogpgcheck –y安装cacti的主程序[rootcacti software]# tar -zxvf cacti-0.8.7g.tar.gz -C /var/www/html/[rootcacti software]# cd /var/www/html/[rootcacti html]# mv cacti-0.8.7g/ cacti[rootcacti html]# service snmpd start[rootcacti html]# chkconfig snmpd on[rootcacti html]# vim /etc/snmp/snmpd.conf添加一行view systemview included .1.3.6.1.2.1.25.1.6 /使能监控tcp流量编辑计划任务[rootcacti html]# crontab -e*/5 * * * * php/var/www/html/cacti/poller.php /dev/null 21导入数据库[rootcacti html]# mysql -u root -p cacti/var/www/html/cacti/cacti.sql输入mysql管理员口令编辑cacti连接数据库的文件[rootcacti html]# vim cacti/include/config.php29 $database_username cacti;30 $database_password cacti;新建一个用户cacti口令也为cacti[rootcacti html]# useradd cacti[rootcacti html]# passwd cacti[rootcacti html]# cd cacti/[rootcacti cacti]# chown -R cacti rra log此时就可以通过页面登录cacti了用户和口令都为admin实现对apache的监控[rootcacti software]# cd ApacheStats_0.8.2/[rootcacti ApacheStats_0.8.2]#lltotal 116-rw-r--r-- 1 root root 102879 Oct 27 18:51 cacti_host_template_webserver_-_apache.xml-rw-r--r-- 1 root root 4108 Oct 27 18:51 ss_apache_stats.php[rootcacti ApacheStats_0.8.2]#cp ss_apache_stats.php /var/www/html/cacti/scripts/[rootcacti ApacheStats_0.8.2]#chown 1000:users /var/www/html/cacti/scripts/ss_apache_stats.phpcacti_host_template_webserver_-_apache.xml 为下面要导入的模版文件通过控制台导入模版修改apache的配置文件[rootcacti ApacheStats_0.8.2]#cd[rootcacti ~]# vim/etc/httpd/conf/httpd.conf217 ExtendedStatus On /打开这一行903 #Location /server-status904 # SetHandler server-status905 # Order deny,allow906 # Deny from all907 # Allow from .example.com908 #/Location909 Location /server-status910 SetHandler server-status911 Order deny,allow912 Deny from all913 Allow from all914 /Location将apache重启[rootcacti ~]# service httpd restart在安装插件之前要先安装插件管理器[rootcacti cacti]# cd /root/software/[rootcacti software]# tar -zxvf cacti-plugin-0.8.7g-PA-v2.8.tar.gz[rootcacti software]# cp -R cacti-plugin-arch/* /var/www/html/cacti/[rootcacti software]# cd /var/www/html/cacti/[rootcacti cacti]# mysql -u root -pcactipa.sql[rootcacti cacti]# patch -p1 -Ncacti-plugin-0.8.7g-PA-v2.8.diff[rootcacti cacti]# vim include/config.php42 $url_path /cacti/;
