用Centos6.3搭建cacti&nagios
来自：网络在CentOS6.3上搭建nagios+cacti+ntop+pnp
CentOS版本： centos-x64 2.6.32-279.el6.x86_64nagios版本：NagiosCore 3.4.2 Cacti版本： cacti-0.8.8a Ntop：ntop-5.0.1 pnp：pnp4nagios-0.6.19
一、配置yum, 更换为163的源
1. 首先备份/etc/yum.repos.d/CentOS-Base.repo #mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup nagios培训
2. 下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份) #[/.help/CentOS6-Base-163.repo].help/CentOS6-Base-163.repo
3. 修改repo文件名称 #mv /etc/yum.repos.d/CentOS6-Base-163.repo /etc/yum.repos.d/CentOS-Base.repo
4. 运行yum makecache生成缓存
5. 安装rpmforge #rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
二、安装包及相关软件 1. 每个人机器的环境不一样，我是用最小安装模式安装的centos，需要安装以上的包，如果还安装过程中提示缺少依赖包，请自行安装吧。 yum install httpd -y yum install php php-mysql php-snmp php-gd -y yum install mysql mysql-server mysql-devel -y yum install net-snmp-utils -y yum install rrdtool* -y yum install gcc* -y yum install gd gd-devel -y yum install glibc* -y yum install make.x86_64 automake -y yum install openssl* -y yum install perl-devel -y yum install GeoIP GeoIP-devel -y yum install ettercap-y yum install libpcap libpcap-devel -y yum install gdbm gdbm-devel -y yum install python python-libspython-devel -y yum install wget-y yum install automake* -y yum install libtool -y yum install subversion -y yum install libdbi libdbi-devel -y yum install libdbi-dbd-mysql –y
2. 配置apache #vi/etc/httpd/conf/httpd.conf，确保有“LoadModule status_module modules/mod_status.so”这行并没有被注释，标示已经支持检测模块，然后启动apache: #servicehttpd start #chkconfig --level 35 httpd on开机启动
3. 配置php #vi/var/www/html/index.php <?php phpinfo(); ?> 访问http://localhost，验证php能够正常工作
4. 配置mysql #servicemysqld start 启动mysql #chkconfig--level 35 mysqld on 设置mysql开机启动 #mysqladmin-u root password 'password' 设置root账号登陆密码
#mysql-u root -p使用root账号登陆 mysql>create database cactidb; 创建数据库cactidb，并创建管理账号cactier nagios实施 mysql>GRANT all Privileges ON cactidb.* TO cactier@localhost IDENTIFIED BY 'password'; mysql>GRANT all Privileges ON cactidb.* TO cactier@127.0.0.1 IDENTIFIED BY 'password'; mysql>flush privileges; 更新权限设置
创建mysql.php验证mysql数据库连接 <?php $link=mysql_connect("localhost","root","password"); if(!$link) echo"FAILD!"; else echo "OK!"; ?> 页面显示OK!表示连接正常。
5. 配置SNMP #vi/etc/snmp/snmpd.conf 编辑SNMP的配置文件，其中修改一下几行 # First, map the community name "public"into a "security name" # sec.namesource community 41 com2sec notConfigUserdefault public#默认的密码为“public”, 可以改为需要的密码 62 accessnotConfigGroup "" any noauth exactall none none 85 view all included.1 80 #service snmpd start 启动SNMP服务 #chkconfig--level 35 snmpd on 设置snmp服务开机启动
三、安装nagios 1. 设置nagios用户和组 #/usr/sbin/useradd-m nagios #passwdnagios #/usr/sbin/groupaddnagios #/usr/sbin/usermod-a -G nagios nagios
2. 安装配置nagios #tarzxf nagios-3.4.2.tar.gz #cd nagios #./configure --with-gd-lib=/usr/lib64--with-gd-inc=/usr/include --with-command-group=nagios--with-httpd-conf=/etc/httpd/conf/ #makeall #makeinstall #makeinstall-init #makeinstall-config #makeinstall-commandmode #makeinstall-webconf #vi/usr/local/nagios/etc/objects/contacts.cfg #htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
vi/etc/httpd/conf/httpd.conf 添加： #nagios default settings Include /etc/httpd/conf/nagios.conf #service httpd restart 访问http://IP/nagios
3. 安装nagios-plugins #tar zxf nagios-plugins-1.4.16.tar.gz #cd nagios-plugins-1.4.16 #./configure--with-nagios-user=nagios --with-nagios-group=nagios #make #makeinstall
4. 安装 nagios-snmp #tar zxf CPAN-1.9800.tar.gz #cd CPAN-1.9800 #perl Makefile.PL #make #make install #yuminstall perl-Time-HiRes -y #perl -MCPAN -e shell (ftp://freesoft.cgi.gov.cn/pub/languages/perl/CPAN ) 监控软件 cpan>installNet::SNMP
#tar zxf nagios-snmp-plugins.1.1.1.tgz #cd nagios_plugins
#chkconfig --add nagios #chkconfig nagios on #/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg #chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin #chcon -R -t httpd_sys_content_t /usr/local/nagios/share #servicenagios start
四、安装cacti 1. 安装 #tar zxvf /root/cacti-0.8.8a.tar.gz #mv /root/cacti-0.8.8a /usr/local/cacti #mysql -u root -p cactidb < /usr/local/cacti/cacti.sql #vi/usr/local/cacti/include/config.php $database_type = "mysql"; $database_default ="cactidb"; $database_hostname ="localhost"; $database_username ="cactier"; $database_password ="password"; $database_port = "3306"; $database_ssl = false;
#adduser -s /sbin/nologin cactier #cd /usr/local/cacti #chown -R cactier rra/ log/ #vi/etc/crontab */5* * * * cactier php /usr/local/cacti/poller.php > /dev/null &
#vi /etc/httpd/conf/cacti.conf Alias /cacti "/usr/local/cacti" <Directory"/usr/local/cacti"> OptionsFollowSymLinks MultiViews AllowOverrideNone Orderallow,deny Allowfrom all </Directory>
2. 配置 #/usr/bin/php -q /usr/local/cacti/poller.php --force --debug 验证php是否有错误，如有：PHP Warning:strtotime()或PHPWarning:date()的警告信息，则 vi/etc/php.ini，修改“;date.timezone=”为“date.timezone= PRC”，然后重启httpd服务。
打开http://IP/cacti/install 进行cacti的安装
五、安装ntop #useradd -M -s /sbin/nologin -r ntop #tarzxvf ntop-5.0.1.tar.gz #cdntop-5.0.1 #./autogen.sh #make #makeinstall #chown-R ntop.ntop /usr/local/share/ntop #chown-R ntop:root /usr/local/share/ntop #ntop -A #ntop -i eth0 -d -L -u ntop #echo 'ntop -i eth0 -d -L -u ntop &> /dev/null' >>/etc/rc.d/rc.local 访问http://IP:3000
六、整合cacti和ntop #tar zxvf ntop-v0.2-1.tgz #mv ntop /usr/local/cacti/plugins/ #vi/usr/local/cacti/include/config.php 添加“$plugins[] = 'ntop';”
七、整合cacti和nagios 1. 安装ndoutils #tar zxf ndoutils-1.5.2.tar.gz #cd ndoutils-1.5.2 #./configure --with-mysql-lib=/usr/lib64/mysql #make #cd /root/ndoutils-1.5.2/db #./installdb -ucactier -p 123#abc -h localhost -d cactidb #cd /root/ndoutils-1.5.2/src cp -v src/{ndomod-3x.o,ndo2db-3x,file2sock,log2ndo} /var/www/html/nagios/bin

#/usr/local/nagios/etc/ndomod.cfg output_type=tcpsocket output=127.0.0.1
为ndo2db添加启动进程 #cp ./daemon-init /etc/init.d/ndo2db #vi /etc/init.d/ndo2db# 检查里面的路径确保不会出现“//"，并将Ndo2dbBin修改成下面的值： nagios配置 Ndo2dbBin=/usr/local/nagios/bin/ndo2db #chmod +x /etc/init.d/ndo2db
#servicendo2db start #tail-20 /var/log/messages ## 查看其中是否有错误出现。如无报错请继续 #/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg 检查nagios配置没有问题 #service nagios restart
2. 安装npc #tar zxf /root/npc-2.0.4.tar.gz #mv /root/npc/ /usr/local/cacti/plugins/ #vi /usr/local/cacti/include/config.php 添加 $plugins[] = 'npc';
3. 为apche添加php支持 #vi /etc/httpd/conf/httpd.conf # 添加一行： AddType application/x-httpd-php .php .phtml # 修改原DirectoryIndex内容为： DirectoryIndex index.html index.html.var index.php

2. 修改nagios配置文件 配置nagios.cfg，修改： #vi/usr/local/nagios/etc/nagios.cfg process_performance_data=1 host_perfdata_command=process-host-perfdata service_perfdata_command=process-service-perfdata
配置commands.cfg，修改： #vi /usr/local/nagios/etc/objects/etc/objects/commands.cfg # 'process-host-perfdata' command definition define command{ command_name process-host-perfdata command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl nagios安装 }
