Cacti的安装(for CentOS 5.2)

系统环境：CentOS 5.2 (Linux)最小化安装+ Development Tools (可以使用yum -y groupinstall Development/ Tools来安装）。#Cacti Readme 中描述所需要的软件包PHP 4.3.6+MySQL 4.1.x or 5.xRRDTool 1.0.49+ or 1.2.xNET-SNMP 5.1.2+#更详细的依赖关系* httpd* php* php-mysql* php-snmp* mysql* mysql-server* net-snmp1. Disable SELinux 关闭SELinuxvi /etc/sysconfig/selinux#SELINUX=enforcingSELINUX=disabled设置完需要重新启动之所以要关闭SELinux是因为国内对SELinux的应用还不普及，假如了解SELinux的使用，那么可以不关闭。正确设置相应的权限即可。2. 下载 Cacti http://www.cacti.netwget http://www.cacti.net/downloads/cacti-0.8.7b.tar.gz3. 安装所需的包yum -y install httpdyum -y install phpyum -y install php-mysqlyum -y install php-snmpyum -y install mysql-serveryum -y install perlyum -y install net-snmp-utils有可能需要安装（没有安装Development Tools的情况下）：yum -y install libpngyum -y install freetypeyum -y install libart_lgpl 4. 将httpd和mysqld设置成自动启动chkconfig httpd onchkconfig mysqld on5. 下载 rrdtool http://oss.oetiker.ch/rrdtool/download.varwget http://dag.wieers.com/rpm/packages/rrdtool/perl-rrdtool-1.2.23-1.el5.rf.i386.rpmwget http://dag.wieers.com/rpm/packages/rrdtool/rrdtool-1.2.23-1.el5.rf.i386.rpm6. 安装 rrdtoolrpm -ivh perl-rrdtool-1.2.23-1.el5.rf.i386.rpm rrdtool-1.2.23-1.el5.rf.i386.rpm7. 修改mysqld配置，将默认字符集设置成utf-8，这样可以方便cacti中显示中文菜单vi /etc/my.cnf[mysqld]collation-server = utf8_general_cidefault-collation = utf8_general_cicharacter-set-server = utf8default-character-set = utf8[mysql]default-character-set = utf88. 建立cacti所需数据库，并设置相关权限，下面其实建了两个用户，适应不同mysql环境。mysqladmin create cactimysql cacti < cacti.sql ( cacti.sql cacti目录下)mysql> create user cacti@’localhost’;mysql> create user cacti@’127.0.0.1′;mysql> grant all privileges on cacti.* to cacti@’localhost’;mysql> grant all privileges on cacti.* to cacti@’127.0.01′;mysql> set password for cacti@’localhost’ = password(‘cactipasswd’);mysql> set password for cacti@’127.0.0.1′ = password(‘cactipasswd’);9. 修改cacti配置文件vi include/config.php ( cacti目录下)$database_type = “mysql”;$database_default = “cacti”;$database_hostname = “localhost”;$database_username = “cacti”;$database_password = “cacitpasswd”;$database_port = “3306″;10. 为cacti配置apache访问vi /etc/httpd/conf.d/cacti.confAlias /cacti /srv/_webapp/cactiOptions Indexes FollowSymLinksAllowOverride NoneOrder allow,denyAllow from all11. 设置cacti数据保存目标权限chown -R apache rra log ( cacti目录下)12.设置cacti采集vi /etc/cron.d/cacti*/5 * * * * apache /usr/bin/php -q /srv/_webapp/cacti/poller.php > /srv/_webapp/cacti/log/poller.log 2>&113. 未提到过的配置文件，均使用系统默认。
