拿台服务器来装cacti了，初期选材选了很久，考虑是用FreeBSD呢，还是用RHEL，甚至还考虑过windows下面装，最后的最后，还是选择CentOS下面装咯。其实看中的是它的稳定和yum的资源。。。
基本上cacti是运作在apache+php+mysql+net-snmp工具集+rrdtool这样的一个工作环境之下，所以我们先要做一个基本的工作的环境。
#yum -y install mysql mysql-server php-mysql
#yum -y install httpd
#yum -y install php
另外还要装一些相关的包：
# yum -y install php-pdo lm_sensors net-snmp php-snmp net-snmp-utils perl-Net-Daemon perl-PlRPC perl-DBI rrdtool perl-rrdtool perl-DBD-MySQL
漫长的waiting...
安装好了，把mysql服务打开，并且设置开机启动httpd和mysql。
#chkconfig mysqld on
#chkconfig httpd on
#servive mysqld start
#chkconfig httpd on
#servive mysqld start
然后是设置数据库的权限：
#mysql -uroot -p
mysql>create database cacti default character set utf8;
mysql>GRANT SELECT, INSERT, UPDATE, DELETE, INDEX, ALTER, CREATE, LOCK TABLES, CREATE TEMPORARY TABLES, DROP, REFERENCES ON cacti.* TO cacti@localhost IDENTIFIED BY 'passwd';
mysql>flush privileges;
mysql> \q
mysql>create database cacti default character set utf8;
mysql>GRANT SELECT, INSERT, UPDATE, DELETE, INDEX, ALTER, CREATE, LOCK TABLES, CREATE TEMPORARY TABLES, DROP, REFERENCES ON cacti.* TO cacti@localhost IDENTIFIED BY 'passwd';
mysql>flush privileges;
mysql> \q
下载中文的cacti,解压到/var/www/cacti.后进入cacti的目录.导入cacti的数据结构
下载地址: cacti-0.8.7a-cn-utf8.tar.gz
# cd /var/www/cacti
# mysql -u cacti -p cacti < cacti.sql
# cd /var/www/cacti
# mysql -u cacti -p cacti < cacti.sql
修改配置文件
# vim /var/www/cacti/include/config.php
# vim /var/www/cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "passwd";
$database_port = "3306";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "passwd";
$database_port = "3306";
添加cacti用户
$useradd cacti -d /var/www/html/cacti -s /bin/false
$chown -R cacti /var/www/html/cacti/rra /var/www/html/cacti/log
这个上面可能添加不行试试:
#chown -hR cacti /var/www/html/cacti/rra /var/www/html/cacti/log
配置httpd服务器的配置文件
# vim /etc/httpd/conf.d/cacti.conf
Alias /cacti /var/www/html/cacti
<Directory /var/www/html/cacti>
DirectoryIndex index.php
AllowOverride all
order deny,allow
deny from all
allow from all
AddType application/x-httpd-php .php
php_flag magic_quotes_gpc on
php_flag track_vars on
</Directory>
<Directory /var/www/html/cacti>
DirectoryIndex index.php
AllowOverride all
order deny,allow
deny from all
allow from all
AddType application/x-httpd-php .php
php_flag magic_quotes_gpc on
php_flag track_vars on
</Directory>
重起httpd的服务，让上面的修改生效
# /etc/init.d/httpd restart
# /etc/init.d/httpd restart
最后的最后让系统每5分钟收集,需要设置
crontab -e
*/5 * * * * cacti php /var/www/cacti/poller.php &>/dev/null
也可手工跑一次:/var/www/cacti/poller.php
crontab -e
*/5 * * * * cacti php /var/www/cacti/poller.php &>/dev/null
也可手工跑一次:/var/www/cacti/poller.php
附：字体在图形中显示不正常的解决方法
下载并安装cjkuni-fonts中文字体，字体名ukai.ttf,下载地址
[url]http://ftp.tw.debian.org/debian/pool/main/t/ttf-arphic-ukai/ttf-arphic-ukai_0.1.20060928.orig.tar.gz[/url]
[url]http://ftp.tw.debian.org/debian/pool/main/t/ttf-arphic-ukai/ttf-arphic-ukai_0.1.20060928.orig.tar.gz[/url]
#tar zxvf ttf-arphic-ukai_0.1.20060928.orig.tar.gz
# cd ttf-arphic-ukai-0.1.20060928/
# cp ukai.ttf /usr/share/fonts/ukai.ttf
# cd ttf-arphic-ukai-0.1.20060928/
# cp ukai.ttf /usr/share/fonts/ukai.ttf
安装完成后注意在"设置"中更改下面两个必改项.
常规->RRDTool应用程序版本 改为1.2.x,默认为1.0.x.不改可能图像不能正常显示出来.
路径->RRDTool默认字体路径 改为上面安装的ukai.ttf的文件路径,如/usr/share/fonts/ukai.ttf
最后大功告成。。。享受cacti !!!
