1.安装与配置cacti

[root@server17 kernel]# tar zxf cacti-0.8.7h.tar.gz -C /usr/local/lnmp/nginx/html/

[root@server17 kernel]# cd /usr/local/lnmp/nginx/html/

[root@server17 html]# mv cacti-0.8.7h/ cacti

[root@server17 cacti]# yum install rrdtool -y

[root@server17 cacti]# vim /usr/local/lnmp/nginx/conf/nginx.conf

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

include fastcgi.conf;

}

[root@server17 cacti]# nginx -s reload

[root@server17 cacti]# /etc/init.d/mysqld start

[root@server17 cacti]# /etc/init.d/php-fpm start

[root@server17 cacti]# mysql

mysql> create database cacti;

mysql> quit

[root@server17 cacti]# mysql cacti < cacti.sql

[root@server17 cacti]# mysql

mysql> grant all on cacti.* to cacti@localhost identified by 'cacti';

mysql> flush privileges;

mysql> quit

[root@server17 cacti]# cd /usr/local/lnmp/nginx/html/cacti/include/

[root@server17 include]# vim config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

$database_ssl = false;

[root@server17 include]# nginx -s reload

访问server17.example.com/cacti出现如下页面：

解决方法如下：

[root@server17 include]# yum list net-snmp*

[root@server17 include]# yum install net-snmp.x86_64 net-snmp-utils.x86_64 net-snmp-perl.x86_64 net-snmp-python.x86_64 -y

按下一步会出现白屏,解决方法如下:

[root@server17 include]# vim /usr/local/lnmp/nginx/html/cacti/lib/functions.php

function kill_session_var($var_name) {

/* register_global = off: reset local settings cache so the user sees the new settings */

unset($_session_unregister[$var_name]);

/* register_global =
on: reset local settings cache so the user sees the new settings */

unset($_SESSION[$var_name]);

}

[root@server17
include]# useradd cacti

[root@server17
include]# chown cacti /usr/local/lnmp/nginx/html/cacti/rra/ -R

[root@server17
include]# chown cacti /usr/local/lnmp/nginx/html/cacti/log/ -R

[root@server17
include]# su - cacti

[cacti@server17
~]$ crontab -e

*/5
* * * * /usr/local/lnmp/php/bin/php
/usr/local/lnmp/nginx/html/cacti/poller.php

[cacti@server17
etc]$ logout

[root@server17
include]# /etc/init.d/crond start

[root@server17
include]# vim /etc/snmp/snmpd.conf

(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

(出现类似上面的输出为正常)

访问server17.example.com/cacti出现如下页面:

注:第一次登录会强制要求更改密码(初始用户名:admin,密码:admin)

出现类似上面图形说明可以正常采集到数据.

#安装插件

[root@server17 kernel]# tar zxf cacti-plugin-0.8.7h-PA-v3.0.tar.gz

[root@server17 kernel]# cd cacti-plugin-arch/

[root@server17 cacti-plugin-arch]# mysql cacti < pa.sql

[root@server17 cacti-plugin-arch]# cp cacti-plugin-0.8.7h-PA-v3.0.diff /usr/local/lnmp/nginx/html/cacti/

[root@server17 cacti]# yum install patch -y

[root@server17 cacti]# patch -p1 -N < cacti-plugin-0.8.7h-PA-v3.0.diff

[root@server17 cacti]# cd include/

[root@server17 include]# vim config.php

$cacti_session_name = "Cacti";

$url_path = "/cacti/";

[root@server17 kernel]# tar zxf settings-v0.71-1.tgz -C /usr/local/lnmp/nginx/html/cacti/plugins

[root@server17 kernel]# tar zxf monitor-v1.3-1.tgz -C /usr/local/lnmp/nginx/html/cacti/plugins

选择User Management

将Plugin Management打上对勾,按save保存.

在Configuration中就会出现Plugin Management这个选项,启动插件.

注：在新版的cacti中已经集成了Plugin Management这个功能，只需将要安装的插件包加压到cacti目录下的plugins目录中，然后在Plugin Management中安装激活即可使用

#安装并配置spine

[root@server17 ~]# yum install net-snmp-devel mysql-devel openssl-devel dos2unix autoconf automake binutils libtool gcc cpp glibc-headers kernel-headers glibc-devel -y

[root@server17 kernel]# tar zxf cacti-spine-0.8.7h.tar.gz

[root@server17 kernel]# cd cacti-spine-0.8.7h

[root@server17 cacti-spine-0.8.7h]# ./bootstrap

[root@server17 cacti-spine-0.8.7h]# ./configure --with-snmp=/usr/ --with-mysql=/usr/local/lnmp/mysql/

[root@server17 cacti-spine-0.8.7h]# make && make install

[root@server17 cacti-spine-0.8.7h]# cd /usr/local/spine/etc/

[root@server17 etc]# cp spine.conf.dist /etc/spine.conf

[root@server17 etc]# vim /etc/spine.conf

DB_Host localhost

DB_Database cacti

DB_User cacti

DB_Pass cacti

DB_Port 3306

DB_PreG 1

(注:如果你用的是cacti087g,将DB_PreG配置为0,否则将 DB_PreG配置为1.)

[root@server17 etc]# /usr/local/spine/bin/spine

此时会出现以下错误:

/usr/local/spine/bin/spine: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

解决方法如下:

[root@server17 etc]# vim /etc/ld.so.conf

include ld.so.conf.d/*.conf

/usr/local/lnmp/mysql/lib

[root@server17 etc]# ldconfig

执行/usr/local/spine/bin/spine出现类似如下结果为正确：

SPINE: Using spine config file [/etc/spine.conf]

SPINE: Version 0.8.7h starting

SPINE: Time: 0.1010 s, Threads: 5, Hosts: 2

选择Settings选项.

选择Paths选项.

如图填写并保存,然后选择Poller选项.

如图选择并保存.

注：观察图像，如果没有出现中断说明spine配置成功.

#监控远程主机(server85.example.com)

以下步骤在server85上实施：

[root@server85 ~]# yum install net-snmp-5.5-41.el6.x86_64 -y

[root@server85 ~]# yum install net-snmp-utils-5.5-41.el6.x86_64 -y

[root@server85 ~]# /etc/init.d/snmpd start

[root@server85 ~]# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex(此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.192.168.122.185 = INTEGER: 2

注：出现类似上面输出,说明配置完成.

以下步骤在server17上实施：

[root@server17 ~]# yum install net-snmp-5.5-41.el6.x86_64 -y

[root@server17 ~]# yum install net-snmp-utils-5.5-41.el6.x86_64 -y

[root@server17 ~]# vim /etc/snmp/snmpd.conf

(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

#com2sec notConfigUser default public

com2sec local localhost public

com2sec mynetwork 192.168.122.0/24 public

[root@server17 ~]# snmpwalk -v 1 -c public 192.168.122.185 IP-MIB::ipAdEntIfIndex(此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

IP-MIB::ipAdEntIfIndex.192.168.122.185 = INTEGER: 2

选择Devices选项，并选择add设备.

如上图填写并保存.

注：如果需要监控root分区的剩余空间，需要将/etc/snmp/snmpd.conf中的disk / 1000这一行的注释去掉，这样在创建图时才有相应的选项，否则无法监控。

选择所要创建的图.

将新添加的设备加入到树中.

至此cacti的安装及配置完毕！！！

2.安装与配置nagios

[root@server17 kernel]# useradd nagios

[root@server17 kernel]# usermod -G nagios nginx(注：通过web更改nagios设置时，需要考虑此权限问题，例如：启动服务通知时)

[root@server17 kernel]# yum localinstall gd-devel-2.0.35-10.el6.x86_64.rpm -y

[root@server17 kernel]# tar jxf nagios-cn-3.2.3.tar.bz2

[root@server17 kernel]# cd nagios-cn-3.2.3

[root@server17 nagios-cn-3.2.3]# ./configure –enable-embedded-perl

3.安装与配置ganglia

[root@server17 kernel]# yum install rpm-build -y

[root@server17 kernel]# rpmbuild -tb ganglia-3.4.0.tar.gz

此时会出现如下错误：

解决方法如下:

[root@server17 kernel]# yum install libart_lgpl-devel python-devel expat-devel apr-devel -y

[root@server17 kernel]# rpm -ivh rrdtool-devel-1.3.8-6.el6.x86_64.rpm

[root@server17 kernel]# rpm -ivh libconfuse-*

中由于对服务的管理机制不一样(由systemv到systemd)，所以在直接进行编译(rpmbuild -tb ganglia-3.6.0.tar.gz)时会出现如下错误:

}

以下步骤在server85上实施：

[root@server85

注：数据存储在/var/lib/ganglia/rrds中，如果重新配置了组名等信息，需要先暂停gmetad和gmond服务,将/var/lib/ganglia/rrds中的文件全部清空，然后启动服务，让服务自动重新建立数据文件。

至此ganglia的安装及配置完毕！！！

首先确保你的php支持pdo和json模块

[root@server17 kernel]# tar zxf npc-2.0.4.tar.gz -C /usr/local/lnmp/nginx/html/cacti/plugins

启动npc插件

启动时会出现如下图的错误，可忽略，重启nginx即可.

选择Setting

选择NPC

查看到类似如上进程为正常

访问server17.example.com/cacti可在npc下看到如下页面

此时执行cat /var/log/messages可看到如下报错：

Jul 13 15:02:25 server17 ndo2db: mysql_error: 'Unknown column 'long_output' in 'field list''

解决方法如下：

当使用的npc插件版本较低时使用如下sql语句向数据库中添加字段：

[root@server17 kernel]# mysql cacti < add-old.sql

add-old.sql中的内容为:

ALTER TABLE `npc_hostchecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_hoststatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_servicechecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_servicestatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_statehistory` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_eventhandlers` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_systemcommands` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

ALTER TABLE `npc_notifications` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

当使用的npc插件版本较高时使用如下sql语句向数据库中添加字段：

[root@server17
kernel]# mysql cacti < add-new.sql

add-new.sql中的内容为:

`service_parentservice_id`

访问server17.example.com/index.php能看到pdo_mysql模块加载成功

访问server17.example.com/cacti能看到如下页面说明配置成功.

至此nagios和cacti整合完毕！！！

监控系统配置完毕！！！
