18 一 10 CentOS 5.4 服务器安装简介

[关键词：cacti,Nagios,CentOS,YUM]

安装适用于Web Blog或者监控等应用涉及到的CentOS Server环境搭建. 简洁而有效！
一. yum -y update
建议所有新装的机器都做此步骤， 国内现在最快的源应该是mirrors.163.com

二. yum install yum install httpd httpd-devel httpd-manual php-pear php php-cli php-common php-devel php-gd php-imap php-mbstring php-mcrypt php-mysql php-snmp php-xml php-xmlrpc php-pear-Auth-SASL php-pear-HTTP-Request php-pear-Mail php-pear-Date php-pear-Net-SMTP php-pear-Net-Socket php-pecl-memcache net-snmp net-snmp-devel net-snmp-libs net-snmp-perl net-snmp-utils mysql mysql-devel mysql-server

安装httpd(Apache),PHP,MySQL， 还有SNMP相关的信息，如果有软件你是已经装过的，这个命令也不会出错而带来异样.

三. chkconfig –level 35 httpd on (将httpd,mysqld等你需要默认INIT 35重启开启的服务设置好）
四. 安装rrdtool
我是安装最新的稳定版本 http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.2.tar.gz
#./configure –prefix=/usr/local
安装此步应该有错误提示， 照着提示将缺失的软件安装上即可,如：yum install pango pango-devel tcl

你要是看到类似与我这样的界面，就恭喜你

Type ‘make’ to compile the software and use ‘make install’ to
install everything to: /usr/local.

… that wishlist is NO JOKE. If you find RRDtool useful
make me happy. Go to http://tobi.oetiker.ch/wish and
place an order.

#make; make install
安装完毕

五. 移动cacti到apache html目录
# mv cacti-0.8.7e /var/www/html/cacti
从浏览器访问CACTI应该会看到如下错误提示：
FATAL: Cannot connect to MySQL server on ‘localhost’. Please make sure you have specified a valid MySQL database name in ‘include/config.php’

我推荐直接从官方文档来操作，地址如：http://www.cacti.net/downloads/docs/html/unix_configure_cacti.html
# mysqladmin –user=root create cacti
# mysql cacti < cacti.sql (要在cacti目录下） # useradd monitor (加个监控账号) # mysql –user=root mysql mysql> grant all on cacti.* to monitor@localhost identified by ‘你想设置的密码’;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

修改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 = “monitor”;
$database_password = “你想设置的密码”;
$database_port = “3306″;

# chown -R monitor rra/ log/
赋予monitor账号权限

OK, 请从浏览器上再次访问CACTI做设置，一看即知
