Cacti 监控服务
一搭建Cacti监控服务器(105)1.1部署服务运行环境(LAMP)
yum -y install httpd php php-mysqlmysql-server
mysql
/etc/init.d/httpd start;chkconfighttpdon
/etc/init.d/mysqld start;chkconfigmysqldon
# mysqladmin-hlocalhost -uroot
password "123"
# mysql -hlocalhost -uroot -p123
mysql>
yum-y install elinks
# cat/var/www/html/test.php
<?php
echo"helloa";
?>
# elinks--dumphttp://localhost/test.php
hello a
#
# cat /var/www/html/linkdb.php
<?php
$linkdb=mysql_connect("localhost","root","123");
if($linkdb){
echo "link ok";
}else{
echo "link no";
}
?>
#
# elinks--dump
http://localhost/linkdb.php
linkok
1.2安装cacti软件
181tar-zxvf cacti-0.8.7g.tar.gz
184mvcacti-0.8.7g /var/www/html/cacti
185chown -Rapache:apache /var/www/html/cacti
修改cacti服务的主文件文件，指定存放配置信息的数据库
vim/var/www/html/cacti/include/config.php
$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "jim";
$database_password = "123";
$database_port = "3306";
:wq
mysql-uroot-p123
mysql> createdatabasecactidb;
mysql>grantalloncactidb.*tojim@"localhost"
identified by "123";
mysql>quit
mysql -hlocalhost -ujim-p123
mysql>quit;
创建存储配置信息的表
# ls /var/www/html/cacti/*.sql
/var/www/html/cacti/cacti.sql
#
mysql -hlocalhost -ujim-p123cactidb<
/var/www/html/cacti/cacti.sql
访问web页面安装cacti
ping 172.40.50.105

1.2 监控远端服务器（ 103）
1.2.1 在服务器103上运行snmpd服务
yum-yinstall net-snmp
# sed -n'41p;62p;85p'
/etc/snmp/snmpd.conf
com2sec notConfigUser172.40.50.105 public
accessnotConfigGroup "" any noauth exactall
none none
view all included.1 80
#
# /etc/init.d/snmpd status
snmpd 已停
# /etc/init.d/snmpd start
正在启动 snmpd： [确定]
# netstat -untlap| grep snmpd
tcp 0 0 127.0.0.1:199 0.0.0.0:*
LISTEN 12339/snmpd
udp 0 0 0.0.0.0:161 0.0.0.0:*
12339/snmpd
#
1.2.2 在监控服务器上监控103
http://172.40.50.105/cacti （使用管理登录管理页面）
1 添加要监控的主机
2 选择监控模板
3 选择监控资源
4 给监控的资源创建图片
5 给监控的主机创建图像树
6 把创建的图片添加的图像树里
7 收集监控数据
8 查看监控信息
++++++++++++++++++++++++++++
1.3 监控本机
1.3.1运行snmpd 服务
rpm-q net-snmp
vim /etc/snmp/snmpd.conf
# sed -n'41p;62p;85p'
/etc/snmp/snmpd.conf
com2sec notConfigUserlocalhost public
accessnotConfigGroup "" any noauth exactall
none none
view all included.1 80
#
# /etc/init.d/snmpd start
正在启动 snmpd： [确定]
# netstat -untlap| grep snmpd
tcp 0 0 127.0.0.1:199 0.0.0.0:*
LISTEN 12339/snmpd
udp 0 0 0.0.0.0:161 0.0.0.0:*
12339/snmpd
#
1.3.2 在监控服务器上监控自己
http://172.40.50.105/cacti （使用管理登录管理页面）
1 添加要监控的主机
2 选择监控模板
3 选择监控资源
4 给监控的资源创建图片
5 给监控的主机创建图像树
6 把创建的图片添加的图像树里
7 收集监控数据
vim /etc/php.ini
946date.timezone = Asia/Chongqing
:wq
php/var/www/html/cacti/poller.php
ls /var/www/html/cacti/rra/*.rra
# crontab-l
*/3* * ** php/var/www/html/cacti/poller.php
# /etc/init.d/crond status
crond (pid1803) 正在运行...

三、配置Cacti监控报警（通过插件实现的）
3.1让cacti支持插件功能
2tar -zxvf cacti-plugin-0.8.7g-PA-v2.9.tar.gz
6mv cacti-plugin-arch/ /var/www/html/cacti/
7cd /var/www/html/cacti/
9which patch
10yum -yinstall patch
11which patch
14patch-N -p1 < cacti-plugin-arch/cacti-plugin-
0.8.7g-PA-v2.9.diff
16lsplugins
index.php
17vim /var/www/html/cacti/include/config.php
$url_path = "/cacti/";
:wq
18cd /var/www/html/cacti/cacti-plugin-arch/
21mysql -uroot -p123 cactidb < pa.sql
登录管理页面启用插件功能
3.2安装插件并激活插件
tar -zxvf monitor-v1.3-1.tgz
tar-zxvf settings-v0.71-1.tgz
tar-zxvf thold-v0.4.9-3.tgz
mv settings/var/www/html/cacti/plugins/
mv thold/var/www/html/cacti/plugins/
mv monitor/var/www/html/cacti/plugins/
# ls/var/www/html/cacti/plugins/
index.phpmonitorsettingsthold
#
3.3配置插件实现监控报警功能（发邮件）
对登录的用户数做监控报警
邮件用户列表 sendmail
设置对监控的资源做监控报警
指定邮件服务器
发邮件 :
发件人 root@localhost
收件人 cactiuser@localhost
邮件服务器 localhost
