cacti的安装配置

一.建立一个虚拟主机
1.vim /etc/httpd/conf.d/vhost.conf
   该文件为新建文件，也可在/etc/httpd/conf/httpd.conf末尾添加，为：
<VirtualHost 192.168.18.144:80>                  /固定格式 ip和端口自己设置
        ServerName cacti.gaowei.com              /域名
        DocumentRoot /web/vhost/cacti-0.8.8a     /路径
        <Directory "/web/vhost/cacti-0.8.8a">    /固定格式，“”里边为路径
            Options Indexes FollowSymLinks       /一些权限，百度可查
            AllowOverride None
            Order allow,deny
            Allow from all
        </Directory>                             /固定格式
        ErrorLog "logs/cacti-error_log"          /报错日志
        CustomLog "logs/cacti-access_log" common /常规日志
</VirtualHost>                                   /固定格式
2.vim /etc/hosts  添加：
192.168.18.144 cacti.gaowei.com

1.tar xvf cacti-0.8.8a -C /web/vhost/    //web/vhost为自己创建的
  cd /web/vhost/cacti-0.8.8a
2.mysqladmin create cactidb              /创建mysql数据库
3.mysql cactidb < cacti.sql              /将cacti.sql导入到数据库
4.mysql -e "GRANT ALL ON cactidb1.* TO cactiuser@localhost IDENTIFIED BY 'cactiuser'"                    /cactidb给用户cactiuser所有权限
                                                        密码为cactiuser
5.mysqladmin flush-privileges             /刷新
6.mysql -ucactiuser -p                    /以cactiuser用户登录
7.mysql>SHOW DATABASES;                   /查看创建的数据库
8.cd include ;vim config.php              /修改如9
9.
/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cactidb";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";
$database_port = "3306";
$database_ssl = false;

/*
   Edit this to point to the default URL of your Cacti install
   ex: if your cacti install as at http://serverip/cacti/ this
   would be set to /cacti/
*/
//$url_path = "/cacti/";
$url_path = "/";
10.service httpd restart
11.useradd cactiuser ；passwd cactiuser
12.chown -R cactiuser:cactiuser rra/ log/
13.vim /etc/php.ini                           /修改如14
14.这个选项设置为date.timezone = Asia/Shanghai
15.echo '*/5 * * * * /usr/bin/php /web/vhost/cacti-0.8.8a/poller.php &>/dev/null' > /var/spool/cron/cactiuser             /每隔5分钟cactiuser用户会执行
                                  poller.php
16.crontab -u cactiuser -e                    /使15写入成功，如果有错，则会报错
17.在浏览器输入
cacti.gaowei.com 会弹出cacti安装提示。按提示安装即可，自带5个数据源，可添加本机对这5个数据源进行监控。
