rhel5.5上安装cacti注意事项

基本环境

os:rhel5.5 i386 rpm:lamp cacti:0.8.8a rrdtool:1.4.5

注意点如下：

一，安装cacti所需要的环境（mysql、mysql-server、httpd、php、php-mysql）-此部署环境并没有默认安装mysql,php,httpd等

yum install mysql ##同时会下载安装perl-DBI yum install mysql-server ##同时会下载安装perl-DBD-MySQL yum install httpd yum install php ##会同时下载安装php-cli ，php-common yum install php-mysql ##会同时下载安装php-pdo

二，安装rrdtoll #yum -y install cairo-devel libxml2-devel pango-develpangolibpng-develfreetypefreetype-devellibart_lgpl-devel 源码包安装rrdtool

#wget http://down1.chinaunix.net/distfiles/rrdtool-1.4.5.tar.gz 您需要设置PKG_CONFIG_PATH，请输入

#export PKG_CONFIG_PATH=/usr/lib/pkgconfig/ #./configure –prefix=/usr/local/rrdtool #make

#make install

#cd /usr/local/rrdtool/share/rrdtool/examples/ #./stripes.pl #ls -l

#cp stripes.png /var/www/html/ （这一步骤的前提是你本机是个WWW服务器器） 在浏览器中输入http://IP/stripes.png ，能看到rrd的示例图说明安装成功； 安装snmp的支持工具 #yum install net-snmp

#yum install net-snmp-utils

三，安装cacti所需要的大量的库 zlib: yum install zib libpng: yum install libpng freetype: yum install freetype jpeg: yum install libjpeg fontconfig: yum install fontconfig gd: yum install gd

libxml: yum install libxml2

源码包安装cacti

#wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz #tar -zxvf cacti-0.8.8a.tar.gz -C /opt

#mv /opt/cacti-0.8.8a /var/www/html/cacti #cd /var/www/html/cacti #vim include/config.php $database_type = \$database_default = \

$database_hostname = \$database_username = \$database_password = \$database_port = \

添加一个cacti用户，并将cacti的安装目录所属用户改为cacti用户 #useradd cacti -d /var/www/html/cacti #chown -R cacti /var/www/html/cacti #chgrp -R cacti /var/www/html/cacti #chmod 755 /var/www/html/cacti 配置cacti数据库

#mysqladmin -uroot password \#mysql –uroot –p

mysql> create database cacti; mysql> use mysql;

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

导入cacti的sql文件

#mysql -uroot -p cacti < /var/www/html/cacti/cacti.sql #service httpd restart 四,后续操作 http://ip/cacti 1,

2,

3,

出现上面错误 #cd /usr/local/bin

#ln–s /usr/local/rrdtool/bin/rrdtoolrrdtool

按F5刷新浏览器即可，后双击Finish完成安装 4,

初始用户名和密码都是admin,第一次登录要更改密码 如下图

Cacti插件安装之NTOP

http://cactiusers.org/downloads/plugins/ 一，Ntop安装

wget http://cdnetworks-kr-2.dl.sourceforge.net/project/ntop/ntop/ntop-4.0.1/ntop-4.0.1.tar.gz 安装环境

Quick Instructions ==================

1. Get and install mandatory packages/tools

These instructions assume your system is already provided with

the normal source compile tools. Most are gnu packages, available through http://www.gnu.org or your favorite prebuilt package source. Using their RedHat package names, these are: -glibc, glibc-devel, gcc, cpp -Some version of awk -libtool (1.4+)

Note that there are reports of success with libtool 1.3.x under FreeBSD so the script allows this. -m4

-autoconf (2.53+) -automake (1.6+) -gdbm, gdbm-devel

-libpcap (http://www.tcpdump.org) -librrdtool

1b. Optional packages

-openssl, openssl-devel (http://www.openssl.org) -zlib, zlib-devel 2. Build ntop -cd ntop

-./autogen.sh -prefix=/usr/local -make

-make install

如果./autoen.sh后make时报错过不去 错误一

checking for GeoIP_record_by_ipnum in -lGeoIP... no Please install GeoIP (http://www.maxmind.com/) 解决方法：

wget http://www.maxmind.com/download/geoip/api/c/GeoIP.tar.gz tarxzvf it ./configure it make it

make install it

错误二

If you run into problems, you can ALWAYS recreate the generated files via this procedure:

rm -f acinclude.m4 aclocal.m4 Makefile.in config.h.in configure Makefile find current versions of libtool, config.guess and config.sub and cp them into your working directory.

cat acinclude.m4.ntop libtool.m4.in > acinclude.m4 aclocal autoheader autoconf

automake --gnu --copy --add-missing and then: ./configure ... make

make install as usual.

二，安装后调试 1，设置ntop

# chown -R nobody /usr/local/var/ntop安全 # ntop -A设置密码 # ntop -i eth0 -d -l

echo \开机启动 http://ip:3000测试

2，配置文件中加入插件 在cacti官网上下载ntop插件

wget http://docs.cacti.net/_media/plugin:ntop-v0.2-1.tgz tarzxvf ntop-v0.2-1.tgz -C /var/www/html/cacti/plugins

# cat /var/www/html/cacti/include/config.php | egrep '^\\$plugins'

$plugins[] = 'ntop';

3，http://ip/cacti

#控制面板-----插件管理---ntop安装和启用 控制面板-----用户管理---admin---选上ntop #控制面板-----设置-----Misc---NTop URL

设置好后cacti上的ntop图标就可调用http://ip:3000出现图像了

Cacti安装插件之thold

基本环境

os:rhel5.5 i386 rpm:lamp cacti:0.8.8a rrdtool:1.4.5

1,安装settings插件

#wget http://docs.cacti.net/_media/plugin:settings-v0.7-1.tgz #mv plugin\\:settings-v0.7-1.tgz settings-v0.7-1.tgz

#tar zxvf settings-v0.7-1.tgz -C /var/www/html/cacti/plugins

2,安装thold插件

#wget http://docs.cacti.net/_media/plugin:thold-v0.4.9-3.tgz #mv plugin\\:thold-v0.4.9-3.tgz thold-v0.4.9-3.tgz

#tar zxvf thold-v0.4.9-3.tgz -C /var/www/html/cacti/plugins 3,更改config.php主配置文件

#cat /var/www/html/cacti/include/config.phps $database_type = \$database_default = \

$database_hostname = \$database_username = \$database_password = \$database_port = \$database_ssl = false; $plugins[] = 'ntop'; $plugins[] = 'npc'; $plugins[] = 'settings'; $plugins[] = 'thold';

4,设置cacti添加进thold

控制面板-----插件管理---settings和thold安装和启用

控制面板-----用户管理---admin---看到选上了thresholds等

看看thold已经安装上了，不过没有配置

Cacti插件安装之nagios

一，安装nagios

useraddnagios必须的，要不make install时过不去 wget

http://cdnetworks-kr-1.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.4.1/nagios-3.4.1.tar.gz

#tar zxvf nagios-3.4.1.tar.gz -C /opt #cd /opt/nagios

#./configure --prefix=/usr/local/nagios #make all

# make install install-base install-cgis install-html install-exfoliation install-config install-init install-

commandmodefullinstall

nagios.conf文件已生成，不用修改

# egrep 'AuthUserFile' /etc/httpd/conf.d/nagios.conf AuthUserFile /usr/local/nagios/etc/htpasswd.users

AuthUserFile /usr/local/nagios/etc/htpasswd.users

创建HTTP认证用户登录Nagios，用户名nagiosadmin，密码123456 #htpasswd -c /usr/local/nagios/etc/htpasswd.usersnagiosadmin 重启apache

#service httpd restart 其他配置基本不用改，启动nagios # servicenagios start # chkconfignagios on http://ip/nagios访问即可

输入密码进入

二，安装Nagios插件

#wgethttp://cdnetworks-kr-1.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz

#tar zxvf nagios-plugins-1.4.16.tar.gz -C /opt #cd /opt/nagios-plugins-1.4.16/

#./configure 新版本已经做的相当好了，什么多余的参数都不用加，但注意时间要正确（因为这个包是16小时前才开发出来的，所以特别是用虚拟机的朋友，时间不能相差的太远） #make

#make install

配置Nagios管理员接受告警信息的邮箱，写入管理员邮箱 # grep email /usr/local/nagios/etc/objects/contacts.cfg

email admin@example.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS 校验

Nagios配置文件，验证配置是否有误 #/usr/local/nagios/bin/nagios -v #service nagios restart

三，PHP支持JSON扩展

PHP必须安装PDO 和 JSON扩展。由于NPC使用了Ext JS，如果没有JSON扩展，NPC的界面不会出来，只能看到一个空白页面。初始

化PHP环境需要用phpize命令，所以也要安装php-devel。

# wget http://www.aurore.net/projects/php-json/php-json-ext-1.2.1.tar.bz2 # tarjxvf php-json-ext-1.2.1.tar.bz2 -C /opt/ # cd /opt/php-json-ext-1.2.1/ # phpize

Configuring for:

PHP Api Version: 20041225 Zend Module Api No: 20050922 Zend Extension Api No: 220051025 #./configure #make

# make install

Installing shared extensions: /usr/lib/php/modules/ # ls /usr/lib/php/modules/

dbase.so gd.so json.so mysqli.so mysql.so pdo_mysql.so pdo.so pdo_sqlite.so phpcups.so

添加支持json扩展 #cd /etc/php.d

#echo \#service httpd restart

四，安装ndoutils

ndoutils是将Nagios的配置及监控信息存储到数据库里，NPC通过调用ndo所存储的数据来展现Nagios的信息。ndoutils需要用到

mysql的mysql-lib及mysql-inc，因此需要安装mysql-devel wget

http://cdnetworks-kr-2.dl.sourceforge.net/project/nagios/ndoutils-1.x/ndoutils-1.5.2/ndoutils-1.5.2.tar.gz

#tar fvxz ndoutils-1.4b7.tar.gz -C /opt #cd /opt/ndoutils-1.5.2

#./configure --prefix=/usr/local/nagios LDFLAGS=-L/usr/lib --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql --enable-mysql --disable-pgsql --with-ndo2db-user=nagios --with-ndo2db-group=nagios #make

#make install #cd src/

# cp ndomod-3x.o ndo2db-3x log2ndo file2sock /usr/bin/ #cd ../config

#cp ndo2db.cfg-sample ndo2db.cfg #cpndomod.cfg-sample ndomod.cfg

#cp ndo2db.cfg ndomod.cfg /usr/local/nagios/etc/ # vim /usr/local/nagios/etc/ndo2db.cfg 修改以下参数

socket_name=/usr/local/nagios/var/ndo.sock db_name=cacti db_prefix=npc_ db_user=cacti db_pass=cacti debug_level=1

debug_file=/usr/local/nagios/var/ndo2db.debug 保存退出

# vimusr/local/nagios/etc/ndomod.cfg 查看以下参数默认不用改

output=/usr/local/nagios/var/ndo.sock

buffer_file=/usr/local/nagios/var/ndomod.tmp

五，安装NPC

# wget http://down.drv5.cn/www.drv5.cn/npc-2.0.4.tar.gz # tar zxvf npc-2.0.4.tar.gz -C /var/www/html/cacti/plugins # vim /var/www/html/cacti/include/config.php 添加以下参数 $plugins[] = 'npc'; #service httpd restart http://ip/cacti

#控制面板-----插件管理---npc安装和启用

控制面板-----用户管理---admin---看到选上ntop

再看NPC出来了，更单独访问http://ip/nagios图像一样

注Cacti-0.8.8a比以前版本更好用，添加插件也更简单
