一.準備三台機器:
Server 192.168.1.19
Client1 192.168.1.11
二.配置（s/c都要安裝）
1.yum install -y net-snmp*
2.cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.$(date +%F-%H)
3.cat >/etc/snmp/snmpd.conf<<EOF

4.cat -n /etc/snmp/snmpd.conf

6.lsof -i :161
7.ps -ef|grep snmpd|grep -v grep
8.snmpget -v 1 -c public localhost system.sysUpTime.0
Server端安裝:
1.tar zxvf libart_lgpl-2.3.17.tar.gz
2../configure
3.make && make install
4./bin/cp -r /usr/local/include/libart-2.0 /usr/include
5.tar zxvf rrdtool-1.2.30.tar.gz
6../configure
报错:configure: error: Please fix the library issues listed above and try again.
解决:yum install -y pango-devel* cairo-devel*
然后:./configure --prefix=/usr/local/rrdtool
7.make && make install
8.ls -l /usr/local/rrdtool/
9.ls -l /usr/local/rrdtool/bin/rrdtool && ln -s /usr/local/rrdtool/bin/rrdtool /usr/local/bin/rrdtool 存在则执行
1.yum install -y gcc glibc glibc-common cairo pango zlib zlib-devel freetype freetype-devel gd
2.yum -y install httpd php mysql mysql-server php-mysql
cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.ori
yum -y remove http*(卸載http服務)
3.sed -i 's##ServerName www.example.com:80#ServerName 127.0.0.1:80#g' /etc/httpd/conf/httpd.conf
4.sed -i 's#DirectoryIndex index.html index.html.var#DirectoryIndex index.php index.html#g' /etc/httpd/conf/httpd.conf 配置首頁文件
6.egrep "127.0.0.1|index" /etc/httpd/conf/httpd.conf 查看信息
7./etc/init.d/httpd start
8.lsof -i :80
9.grep DocumentRoot httpd.conf 查看站點目錄
10.echo -e "<?php phpinfo(); ?>" /var/www/html/index.php
IE登錄192.168.1.19/index.php 查看是否有php顯示
11./etc/init.d/mysqld start
12.lsof -i :3306
13.mysql
14.GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY'cactiuser';創建用戶密碼,并授權
15.flush privileges; 權限刷新
16.create database cacti;
17.quit
18.tar zxvf cacti-0.8.8a.tar.gz
19.cd cacti-0.8.8a
20.mysql cacti <cacti.sql 初始化cacti数据库
21.mysql -e "use cacti;show tables;"
22.vim include/config.php 在其中修改信息
23.grep database include/config.php
24.chown -R apache rra/ log/ 授权Apache访问
25.mv ../cacti-0.8.8a /var/www/html/cacti 页面拷贝
26.chown -R apache.apache cacti
27./usr/bin/php /var/www/html/cacti/poller.php 测试收集php文件
28.chown 755 /var/www/html/cacti/poller.php
29.echo '*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php >/dev/null 2>&1' >>/var/spool/cron/root
30.setenforce 0
31./etc/init.d/iptables stop
通过cacti监控服务器并发连接数配置
1.unzip get_netstat_conn.zip
2.tree get_netstat_conn
3.mv get_netstat_conn/get_netstat_tcp_oldboytrainning.pl /var/www/html/cacti/scripts/
4.chmod 755 /var/www/html/cacti/scripts/get_netstat_tcp_oldboytrainning.pl
cd /var/www/html/cacti/scripts/
perl get_netstat_tcp_oldboytrainning.pl 127.0.0.1 2c public 161 500 只有返回数据,才能监控到数据出图
