Cacti 0.8.7g在CentOS5.5上的安装.docx

Cacti 0.8.7g在CentOS5.5上的安装1.系统的安装这次我用的是CentOS5.5-i386，在选择安装包时一个包都不需要装，就以最小系统。配置好IP等。A.关闭SElinuxvi /etc/sysconfig/selinux# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:#?????? enforcing - SELinux security policy is enforced.#?????? permissive - SELinux prints warnings instead of enforcing.#?????? disabled - SELinux is fully disabled.SELINUX=enforcing# SELINUXTYPE= type of policy in use. Possible values are:#?????? targeted - Only targeted network daemons are protected.#?????? strict - Full SELinux protection.SELINUXTYPE=targeted把SELINUX=enforcing改为SELINUX=disabled并保存！在这个时候SElinux还在运行我们用setenforce 0来关闭SElinuxB.防火墙一般我都是把防火墙直接关掉/etc/init.d/iptables stop/etc/init.d/ip6tables stopchkconfigiptables offchkconfig ip6tables off2.配置cacti需要的软件环境A.由于一些包在官方的库中没有，因此我们要建立dag.repo，定义非官方库vi /etc/yum.repos.d/dag.repo内容如下[dag]name=Dag RPM Repository for Red Hat Enterprise Linuxbaseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/daggpgcheck=1enabled=1然后再导入非官方库的GPG：rpm --import /rpm/packages/RPM-GPG-KEY.dag.txtB.安装cacti需要的环境包yum install -y httpdmysqlmysql-server phpphp-mysql net-snmp net-snmp-utilsyum install -y zliblibpngfreetypelibjpegfontconfiggd libxml2?yum install -y rrdtoolC.为cacti创建数据库和用户servicemysqld start/usr/bin/mysqladmin --user=root create cactimysql -e GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 3.下载cacti-0.8.7g.tar.gz并解压、MVcd /var/www/html/yum install wget -ywget /downloads/cacti-0.8.7g.tar.gztarxf cacti-0.8.7g.tar.gzrm -rf cacti-0.8.7g.tar.gzcd cacti-0.8.7g/mv * ../cd ..rm -rf cacti-0.8.7g/mysql -ucactiuser - cacti /var/www/html/cacti.sql修改cacti的配置文件并保存vi /var/www/html/include/config.php/* make sure these values refect your actual database/host/user/password */$database_type = mysql;$database_default = cacti;$database_hostname = localhost;$database_username = cactiuser;$database_password = ;$database_port = 3306;设置crontab定时任务由于我们是最小系统安装没有安装定时任务，因此我们首先安装yum install vixie-cron然后我们添加定时任务cho */5 * * *
