Centos 7 install cacti監控

 

首先，先安裝LNMP服務

安裝一：

若是以爲安裝起來麻煩，能夠到以下網站進行安裝；

https://lnmp.org/install.html

安裝二：

採用yum或者安裝包的方式進行安裝，具體操做請參照百度。

 

開始配置Cacti

1：安裝net-snmp簡單網絡管理協議

yum install -y net-snmp net-snmp-libs net-snmp-utils net-snmp-devel net-snmp-perl

2：安裝RRDTool 繪圖工具

yum install -y rrdtool rrdtool-devel rrdtool-php rrdtool-perl perl-devel perl-CPAN perl-YAML

3:配置SNMP
修改snmp配置文件，找到以下內容修改
vim /etc/snmp/snmpd.conf
//修改default爲本機ip，修改public爲本身的團體名（能夠不改），41行
com2sec notConfigUser default public
//把systemview改爲all ,供全部snmp 訪問權限 62行
access notConfigGroup "" any noauth exact all none none
//去掉此行註釋
view all included .1 80 // 去掉#號 85行
重啓snmp服務

systemctl restart snmpd.service && systemctl enable snmpd.service

4：修改PHP時區
vim /usr/local/php/etc/php.ini
[PHP]
safe_mode = Off
……
date.timezone = Asia/Shanghai

5：修改Mysql配置文件
vim /etc/my.cnf
在文件最末尾新建[server]區域，複製進去如下內容
[server]

# this is only for the mysqld standalone daemon
character_set_server = utf8mb4
collation-server = utf8mb4_unicode_ci
max_heap_table_size = 256M
max_allowed_packet = 16777216
tmp_table_size = 64M
join_buffer_size = 64M
innodb_file_per_table = ON
innodb_buffer_pool_size = 1024M
innodb_doublewrite = OFF
#innodb_additional_mem_pool_size = 96M
innodb_flush_log_at_timeout = 3
innodb_read_io_threads = 32
innodb_write_io_threads =16

註釋掉[mysqld]區域下的
#max_allowed_packet = 1M

/etc/init.d/mysql restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!

6：下載cacti安裝包
wget https://www.cacti.net/downloads/cacti-1.1.38.tar.gz
tar zxvf cacti-1.1.38.tar.gz
cp -R cacti-1.1.38 /home/wwwroot/default/cacti

7：建立cacti數據庫

[root@localhost /]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.7.18-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> create database cacti;
Query OK, 1 row affected (0.00 sec)

mysql> grant all on cacti.* to cactiuser@localhost identified by "cactiuser";
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> GRANT SELECT ON mysql.time_zone_name TO 'cactiuser'@'localhost' IDENTIFIED BY 'cactiuser';
Query OK, 0 rows affected, 1 warning (0.00 sec)

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

注意：這裏的數據庫用戶名密碼所有爲cactiuser,能夠自定義。

8：導入cacti數據文件
mysql> use cacti;
Database changed
mysql> source /home/wwwroot/default/cacti/cacti.sql
Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

....................................
Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

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

mysql> exit
Bye

9：配置數據庫時區
cd /usr/local/mysql/bin/
./mysql_tzinfo_to_sql /usr/share/zoneinfo/ | mysql -u root -p mysql
Enter password:
Warning: Unable to load '/usr/share/zoneinfo//iso3166.tab' as time zone. Skipping it.
Warning: Unable to load '/usr/share/zoneinfo//zone.tab' as time zone. Skipping it.

10：cacti配置文件config.php

主要修改數據庫用戶名密碼，和cacti路徑，這裏所有默認，根據我的配置進行修改
vim /home/wwwroot/default/cacti/include/config.php
$database_type = 'mysql';
$database_default = 'cacti';
$database_hostname = 'localhost';
$database_username = 'cactiuser';
$database_password = 'cactiuser';
$database_port = '3306';
$database_ssl = false;

11：建立 cacti 系統用戶，設置目錄權限

useradd -r -M cacti
chown -R cacti /home/wwwroot/default/cacti/{rra,log}/
chown -R www:www /home/wwwroot/default/cacti/{resource,cache,scripts}
chmod -R 777 /home/wwwroot/default/cacti/

12：添加定時任務
[root@localhost bin]# crontab -e
*/5 * * * * cactiuser php /home/wwwroot/default/cacti/poller.php > /dev/null 2>&1

no crontab for root - using an empty one
crontab: installing new crontab

13：從新啓動相關服務
systemctl restart crond && systemctl restart snmpd

14：安裝spine
cacti默認使用cmd.php來輪詢數據，速度會很慢，所以咱們採用Spine來輪詢數據。cacti-spine是一個由C語言開發的，用於替代cmd.php的快速獲取速度的引擎。（也能夠不裝）
安裝spine高速數據採集插件

15：訪問ip

 查看是否完成配置，按照提示操做進行一步步安裝。
