所需的包:cacti-0.8.8b.tar.gz cacti-spine-0.8.8b.tar.gz settings-v0.71-1.tgz monitor-v1.3-1.tgz thold-v0.4.9-3.tgz nagios-cn-3.2.3.tar.bz2 nagios-plugins-1.4.16.tar.gz gd-devel-2.0.35-10.el6.x86_64.rpm fetion linuxso_20101113.tar.gz nrpe-2.14.tar.gz ganglia-3.6.0.tar.gz ganglia-web-3.5.10.tar.gz libconfuse-2.6-3.el6.x86_64.rpm libconfuse-devel-2.6-3.el6.x86_64.rpm rrdtool-devel-1.3.8-6.el6.x86_64.rpm npc-2.0.4.tar.gz ndoutils-1.5.2.tar.gz

1.安装与配置cacti

 

[root@server19 kernel]# yum install httpd mysql-server php rrdtool -y

[root@server19 kernel]# yum install php-mysql php-xml mysql net-snmp net-snmp-utils.x86_64 -y

[root@server19 kernel]# rpm -ivh php-snmp-5.3.3-22.el6.x86_64.rpm

注：因为在红帽企业7中用mariadb替代了mysql,所以需要将mysql和mysql-server换成mariadb和mariadb-server.并且php-snmp的版本必须与企业7中php的版本一致，可以通过rpm -q php查看php的版本.

[root@server19 kernel]# vim /etc/php.ini

safe_mode = Off

date.timezone = Asia/Shanghai

file_uploads = On

[root@server19 kernel]# mysql_secure_installation (给数据库设置密码)

[root@server19 kernel]# vim /etc/snmp/snmpd.conf

(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

#com2sec notConfigUser default public

com2sec local localhost public

com2sec mynetwork 192.168.122.0/24 public

syslocation rhel6.4 (edit /etc/snmp/snmpd.conf)

syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

[root@server19 kernel]# /etc/init.d/snmpd start

[root@server19 kernel]# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex (此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.192.168.122.119 = INTEGER: 2

(出现类似上面的输出为正常)

[root@server19 kernel]# tar zxf cacti-0.8.8b.tar.gz -C /var/www/html/

[root@server19 kernel]# mysqladmin -uroot -pwestos create cacti

[root@server19 kernel]# cd /var/www/html/

[root@server19 html]# ln -s cacti-0.8.8b/ cacti

[root@server19 html]# cd cacti

[root@server19 cacti]# mysql -uroot -pwestos cacti < cacti.sql

[root@server19 cacti]# mysql -uroot -pwestos

mysql> grant all on cacti.* to cacti@localhost identified by 'cacti';

mysql> flush privileges;

mysql> quit

[root@server19 cacti]# cd /var/www/html/cacti/include/

[root@server19 include]# vim config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

$database_ssl = false;

$url_path = "/cacti/";

$cacti_session_name = "Cacti";

[root@server19 include]# useradd cacti

[root@server19 include]# chown cacti /var/www/html/cacti-0.8.8b/ -R

[root@server19 include]# su - cacti

[cacti@server19 ~]$ crontab -e

*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1

[root@server19 include]# /etc/init.d/httpd start

 

访问server19.example.com/cacti出现如下页面:

注：net-snmp和rrdtool的版本设置需要与本机的版本匹配，可以通过rpm -q net-snmp和rpm -q rrdtool查看版本.

注:第一次登录会强制要求更改密码(初始用户名:admin,密码:admin)

出现类似上面图形说明可以正常采集到数据.

#安装并配置spine

[root@server19 kernel]# yum install net-snmp-devel mysql-devel openssl-devel dos2unix autoconf automake binutils libtool gcc cpp glibc-headers kernel-headers glibc-devel -y

注：因为在红帽企业7中用mariadb替代了mysql,所以需要将mysql-devel换成mariadb-devel.

[root@server19 kernel]# tar zxf cacti-spine-0.8.8b.tar.gz

[root@server19 kernel]# cd cacti-spine-0.8.8b

[root@server19 cacti-spine-0.8.8b]# ./bootstrap

[root@server19 cacti-spine-0.8.8b]# ./configure

[root@server19 cacti-spine-0.8.8b]# make && make install

[root@server19 cacti-spine-0.8.8b]# cd /usr/local/spine/etc/

[root@server19 etc]# cp spine.conf.dist spine.conf

[root@server19 etc]# vim spine.conf

DB_Host localhost

DB_Database cacti

DB_User cacti

DB_Pass cacti

DB_Port 3306

DB_PreG 1

(注:如果你用的是cacti087g,将DB_PreG配置为0,否则将 DB_PreG配置为1.)

[root@server19 etc]# cp spine.conf /etc/

[root@server19 etc]# /usr/local/spine/bin/spine

PINE: Using spine config file [spine.conf]

INE: Version 0.8.8b starting

INE: Time: 0.1288 s, Threads: 5, Hosts: 2

出现类似以上输出为正确.

选择Settings选项.

选择Paths选项.

如图填写并保存,然后选择Poller选项.

如图选择并保存.

注：观察图像，如果没有出现中断说明spine配置成功.

 

 

 

#安装插件

 

[root@server19 kernel]# tar zxf settings-v0.71-1.tgz -C /var/www/html/cacti/plugins

 

[root@server19 kernel]# tar zxf monitor-v1.3-1.tgz -C /var/www/html/cacti/plugins

 

[root@server19 kernel]# tar zxf thold-v0.4.9-3.tgz -C /var/www/html/cacti/plugins

在Configuration中就会出现Plugin Management这个选项,启动插件.

注：在新版的cacti中已经集成了Plugin Management这个功能，只需将要安装的插件包加压到cacti目录下的plugins目录中，然后在Plugin Management中安装激活即可使用
