[rhel6.5]cacti的安裝配置

• rhel6.5安裝配置

  cacti

  兩台主機:

  IP:

  172.25.23.20

  172.25.23.21

  核心版本

  2.6.32-431.el6.x86_64

  軟體版本:

  cacti-0.8.8h.tar.gz

  cacti-spine-0.8.8h.tar.gz

• 首先在

  172.25.23.20

  上面安轉

  cacti

  依賴的軟體包

• 安裝

  Yum

  沒有提供的軟體包

  php-snmp

  ,通過軟體包

  php-snmp-5.3.3-26.el6.x86_64.rpm

  來進行安裝

[root@server20 ~]# rpm -ivh /mnt/php-snmp-5.3.3-26.el6.x86_64.rpm
warning: /mnt/php-snmp--el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   :php-snmp               ########################################### [100%]
           

• 編輯配置檔案更改時區

[[email protected] ~]# vim /etc/php.ini 
[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone = Asia/Shanghai
           

• 解壓cacti的主檔案,到httpd的釋出目錄裡面

[[email protected] mnt]# tar zxf cacti-0.8.8h.tar.gz -C /var/www/html/
[[email protected] mnt]# ln -sv /var/www/html/cacti-0.8.8h/ /var/www/html/cacti
`/var/www/html/cacti' -> `/var/www/html/cacti-0.8.8h/
           

• 啟動httpd服務:

[root@server20 html]# /etc/init.d/httpd start
Starting httpd:                                            [  OK  ]
           

• 確定服務的啟動狀态是正常的

  

• 修改cacti的配置檔案cacti/include/config.php 關于資料庫連接配接的選項

[[email protected] html]# vim cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "westos";
$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 = "/cacti/";

/* Default session name - Session name must contain alpha characters */
//$cacti_session_name = "Cacti";
$cacti_session_name = "Cacti";
           

• 啟動myql資料庫并且進行資料庫的安全設定,因為這是安裝資料庫之後的第一次使用

[[email protected] html]# /etc/init.d/mysqld start
Initializing MySQL database:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h server20.com password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]
           

• 確定啟動狀态是正常的

  

• 執行資料庫的安全配置腳本

[[email protected] html]# mysql_secure_installation 




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...



All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL

• 切換到這個使用者并且建立定時任務

[root@server20 cacti]# su - cacti
[cacti@server20 ~]$ crontab -e
*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null >&

crontab: installing new crontab
[cacti@server20 ~]$ logout
           

• 複制時區檔案到系統時間檔案裡面

[[email protected] rra]# cd /usr/share/zoneinfo/Asia/
[[email protected] Asia]# pwd
/usr/share/zoneinfo/Asia
[[email protected] Asia]# cp Shanghai /etc/localtime 
cp: overwrite `/etc/localtime'? y
           

• 關于localhost使用cacti來監控系統性能的配置已經完成,接下來配置

  cacti

  監控

  172.25.23.21

• 首先安裝

  net-snmp-*

• 啟動snmpd服務:

[root@server21 ~]# /etc/init.d/snmpd start 
Starting snmpd:                                            [  OK  ]
[root@server21 ~]# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex
           

• 修改配置檔案如下

[[email protected] ~]# vim /etc/snmp/snmpd.conf 
# First, map the community name "public" into a "security name"

#       sec.name  source          community
#com2sec notConfigUser  default       public
com2sec local           localhost       westos
com2sec mynetwork       172.25.23.0/24  westos

# Second, map the security name into a group name:

#       groupName      securityModel securityName
#group   notConfigGroup v1           notConfigUser
#group   notConfigGroup v2c           notConfigUser

group   MyRWGroup       v1              local
group   MyRWGroup       v2c             local
group   MyRWGroup       usm             local

group   MyROGroup       v1              mynetwork
group   MyROGroup       v2c             mynetwork
group   MyROGroup       usm             mynetwork

# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v  localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   
view    systemview    included   

view all included                                     

# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
#access  notConfigGroup ""      any       noauth    exact  systemview none none

access  MyROGroup ""      any       noauth    exact  all none none
access  MyRWGroup ""      any       noauth    exact  all all none

#syslocation Unknown (edit /etc/snmp/snmpd.conf)
#syscontact Root <[email protected]> (configure /etc/snmp/snmp.local.conf)


syslocation RHEL6
syscontact Root  <[email protected]>

# Check the / partition and make sure it contains at least  megs.

#disk / 
disk / 
           

• 使用指令探測

  snmpd

  服務是否正常啟動

[[email protected] ~]# snmpwalk -v 1 -c westos localhost IP-MIB::ipAdEntIfIndex
IP-MIB::ipAdEntIfIndex = INTEGER: 
IP-MIB::ipAdEntIfIndex = INTEGER: 
           

• 顯示的結果如下:

• 在

  server20.com

  上面進行探測

• 確定探測的結果如下

  

• 是上面對于配置檔案的修改,可以通過檢查錯誤日志來檢視檔案的修改是否是正确的
• 檔案是

  /var/log/messages

  ,

  

• 點選

  device

  之後,點選

  Add

  

• 按照這個要求進行建立

  

  

• 建立

  server21.com

  的圖形

  

  

• 接下來點選

  Graphy tree

  和

  default tree

  

• 接下來點選

  add

  用于添加新的圖形界面

  

• 這裡 改為

  host

  然後點選

  save

  進行儲存

  

• 這裡就可以看到

  hosts server21.com

  發送回來的資訊了

  

• 接下來配置

  cacti-spine-0.8.8h

• 首先編譯環境的依賴問題

• 然後執行

[root@server20 ~]# tar zxf cacti-spine-0.8.8h.tar.gz -C /usr/local/
[root@server20 ~]# cd /usr/local/cacti-spine-0.8.8h/

[root@server20 cacti-spine-.h]# sh bootstrap 
           

• 直到出現這個畫面

  

• 執行

[root@server20 cacti-spine-.h]# ./configure 
[root@server20 cacti-spine-.h]# make
[root@server20 cacti-spine-.h]# make install 
           

• 首先複制配置檔案

[root@server20 local]# cd spine/
[root@server20 spine]# ls
bin  etc
[root@server20 spine]# cd etc/
[root@server20 etc]# ls
spine.conf.dist
[root@server20 etc]# pwd
/usr/local/spine/etc
[root@server20 etc]# cp spine.conf.dist /etc/spine.conf
           

• 修改

  poller Type

  的類型為

  spine

  

• 同時還需要添加

  spine

  的配置路徑

  

• 然後更改配置檔案,添加連接配接資料庫的資訊

[root@server20 bin]# vim /etc/spine.conf
DB_Host         localhost
DB_Database     cacti
DB_User         cacti
DB_Pass         westos
DB_Port         
           

• 使用絕對路徑的方式啟動服務

• 通過上面的方式就完成了,插件

  spine

  的配置
