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.x RRDTool 1.0.49+ or 1.2.x NET-SNMP 5.1.2+ #更详细的依赖关系 * httpd * php * php-mysql * php-snmp * mysql * mysql-server * net-snmp 1. Disable SELinux 关闭SELinux vi /etc/sysconfig/selinux #SELINUX=enforcing SELINUX=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.net wget http://www.cacti.net/downloads/cacti-0.8.7b.tar.gz 3. 安装所需的包 yum -y install httpd yum -y install php yum -y install php-mysql yum -y install php-snmp yum -y install mysql-server yum -y install perl yum -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 libpng yum -y install freetype yum -y install libart_lgpl 4. 将httpd和mysqld设置成自动启动 chkconfig httpd on chkconfig mysqld on 5. 下载 rrdtool http://oss.oetiker.ch/rrdtool/download.var wget http://dag.wieers.com/rpm/packages/rrdtool/perl-rrdtool-1.2.23-1.el5.rf.i386.rpm wget http://dag.wieers.com/rpm/packages/rrdtool/rrdtool-1.2.23-1.el5.rf.i386.rpm 6. 安装 rrdtool rpm -ivh perl-rrdtool-1.2.23-1.el5.rf.i386.rpm rrdtool-1.2.23-1.el5.rf.i386.rpm 7. 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_ci default-collation = utf8_general_ci character-set-server = utf8 default-character-set = utf8 [mysql] default-character-set = utf8 8. 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 cacti mysql cacti 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.conf Alias /cacti /srv/_webapp/cacti <directory> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </directory> 11. 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>&1 13. 未提到过的配置文件，均使用系统默认。
