一 cacti的安装并接监控本机
1所需要的软件
yum install mysql php httpd rrdtool mysql-server php-mysql php-snmp net-snmp
2. 启动snmp
/etc/init.d/snmpd restart
3.验证snmp是否有用,没用别且修改
参照的东东是
http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/mrtg_config_step_3.php
yum install *snmpwalk* -y
snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex 查看snmp是否有用
vi /etc/snmp/snmpd.conf
Change/Modify line(s) as follows:
Find following Line:
com2sec notConfigUser default public
Replace with (make sure you replace 192.168.0.0/24 replace with your network IPs) following lines:
com2sec local localhost public
com2sec mynetwork 192.168.0.0/24 public
Scroll down bit and change:
Find Lines:
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
Replace with:
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
group MyROGroup v1 mynetwork
group MyROGroup v2c mynetwork
group MyROGroup usm mynetwork
Again scroll down bit and locate following line:
Find line:
view systemview included system
Replace with:
view all included .1 80
Again scroll down bit and change:
Find line:
access notConfigGroup "" any noauth exact systemview none none
Replace with:
access MyROGroup "" any noauth exact all none none
access MyRWGroup "" any noauth exact all all none
Scroll down bit and change:
Find lines:
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root (configure /etc/snmp/snmp.local.conf)
Replace with (make sure you supply appropriate values):
syslocation Rhel6.1
syscontact 15802955296@139.com
4.启动snmp 再次验证是否有用
5 启动mysql
/etc/init.d/mysqld restart
6.下载cacti,和cacti-spine,并且解压缩2个软件移动到httpd的发布目录下,别且改名为自己要访问的目录
tar zxf cacti-0.8.7g.tar -C /var/www/html
cd /var/www/html
mv cacti-0.8.7g/ cacti
7.创建mysql的用户cacti
cd /var/www/html/cacti
mysqladmin create cacti
8 将cacti的数据库导入mysql
mysql cacti < cacti.sql
9进入mysql
给予cacti用户和密码 别且允许其查看cacti.sql
mysql
grant all on cacti.* to cacti@localhost identified by 'cacti';
10使用mysql -ucacti -pcacti登录数据库别且查看是否有cacti数据库
show databases;
11 修改cacti的配置文件
cd /var/www/html/cacti/include
vi config.php
将 数据库的用户名密码改为自己的 cacti
12建立用户cacti
useradd cacti
13 给予cacti用户的权限(日志和数据)
cd /var/www/html/cacti
chown -R cacti rra log
14 进入cacti用户建立
crontab -e
*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1
15重启 httpd mysqld snmpd
访问到cacti成功
二 cacti的扩展
1.下载软件 cacti-spine-0.87g
tar zxf cacti-spine-0.87gyum insta
cd cacti-spine
2.安装所需要的软件
yum install automake-1.11.1.1.2.el6 *libtoolize* autoconf-2.63.5.1.el6 mysql-devel net-snmp-devel
aclocal
libtoolize --force
aoutoheader
autoconf
automake
./configure
make && make install
3.cd /usr/local/spine/etc
mv spine.conf.dist spine.conf
vi spine.conf
用户名密码 改为自己的
cactiDB_Host localhost
DB_Database cacti
DB_User cacti
DB_Pass cacti
DB_Port 3306
DB_PreG 0
/etc/init.d/httpd restart
/etc/init.d/snmpd restart
访问http://192.168.0.5/cacti
User: useradmin admin
Passwd useradmin admin
将concle—settings-paths的Spine Poller File Path的路径改为
/usr/local/spine/bin/spine
将concle—settings-poller 第一项改为spine
如下图:
本机的自己监控就完成了
二 cacti监控插件的安装
tar zxf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
cd cacti-plugin-arch/
cp cacti-plugin-0.8.7g-PA-v2.8.diff /var/www/html/cacti/
yum install patch -y
cd /var/www/html/cacti/include/
cd /root/cacti-spine-0.8.7g
tar zxf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
cd cacti-plugin-arch/
mysql cacti < pa.sql
