CentOS7安裝Cacti1.1.38（親測可用）

1.軟件安裝
1.1 更新系統

yum -y install wget vim-enhanced
mkdir /etc/yum.repos.d/backup
mv /etc/yum.repos.d/{*.repo,backup}
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.163.com/.help/CentOS7-Base-163.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
rm -rf /var/cache/yum
rm -rf /var/cache/man
yum makecache
yum update

1.2 安裝 Cacti 部署環境所需軟件包
1.2.1 添加 MariaDB YUM 倉庫，執行以下腳本

echo '# MariaDB 10.2 CentOS repository list - created 2017-07-03 06:59 UTC 
#http://downloads.mariadb.org/mariadb/repositories/ 
[mariadb]
name = MariaDB
baseurl = https://ipv4.mirrors.ustc.edu.cn/mariadb/yum/10.2/centos7-amd64
gpgkey=https://ipv4.mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck=1
'>/etc/yum.repos.d/Mariadb.repo

1.2.2 安裝軟件環境

yum install -y httpd mariadb mariadb-server mariadb-devel net-snmp net-snmp-utils net-snmp-libs net-snmp-agent-libs net-snmp-devel php php-snmp php-ldap php-pdo php-mysql php-devel php-pear php-common php-gd php-mbstring php-xml php-process rrdtool rrdtool-php rrdtool-perl rrdtool-devel gcc openssl-devel dos2unix autoconf automake binutils libtool cpp postfix glibc-headers kernel-headers glibc-devel gd gd-devel help2man ntpdate wget patch

2.環境配置
2.1 配置 PHP
修改 PHP 主配置文件 /etc/php.ini
關閉安全模式，以支持 rrdtool，允許 exec() 訪問

[PHP]
safe_mode = Off

設置時區

[Date]
date.timezone = Asia/Shanghai

2.2 配置 Web 服務器 Apache httpd
編輯 /etc/httpd/conf.d/php.conf 配置文件，確保文件含有

# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
LoadModule php5_module modules/libphp5.so
#
# Cause the PHP interpreter to handle files with a .php extension.
AddHandler php5-script .php

2.3 配置數據庫 MariaDB
爲安全起見，設置數據庫 root 用戶密碼

systemctl start mariadb
mysqladmin -uroot password xxx123

導入時區數據到 mysql 數據庫

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -uroot mysql -p

修改 /etc/my.cnf.d/server.cnf 文件，確保文件含有

[mysqld]
character_set_server = utf8mb4
collation_server = utf8mb4_unicode_ci
character_set_client = utf8mb4
max_connections = 100
max_heap_table_size = 4096M
max_allowed_packet = 16777216
join_buffer_size = 64M
tmp_table_size = 64M
innodb_file_per_table = ON
innodb_buffer_pool_size = 25600M
innodb_doublewrite = OFF
innodb_lock_wait_timeout = 50
innodb_flush_log_at_timeout = 3
innodb_read_io_threads = 32
innodb_write_io_threads = 16

2.4 配置 SNMP
配置 net-snmp-agent, 修改配置文件 /etc/snmp/snmpd.conf
將41行
com2sec notConfigUser default public
改爲
com2sec notConfigUser 127.0.0.1 public
將62行
access notConfigGroup "" any noauth exact systemview none none
改爲
access notConfigGroup "" any noauth exact all none none
將85行
#view all included .1 80
改爲
view all included .1 80
3.安裝配置 Cacti
3.1 下載解壓 Cacti 安裝包

useradd -r -M cacti
cd /var/www/html/
wget https://github.com/Cacti/cacti/archive/release/1.1.38.tar.gz
tar -zxvf 1.1.38.tar.gz
cp -R cacti-release-1.1.38/ /var/www/html/cacti
cd /var/www/html/cacti

3.2 創建 cacti 數據庫，創建 cactiuser 用戶，設置相關授權

mysql -u root -p
CREATE database cacti default character set utf8;
create user 'cacti'@'localhost' identified by 'xxx3';
grant all privileges on cacti.* to cacti@localhost;
grant select on mysql.time_zone_name to 'cacti'@'localhost' identified by 'xxx3';
flush privileges;

3.3 導入 Cacti 默認數據庫

use cacti;
source /var/www/html/cacti/cacti.sql;
flush privileges;
quit

3.4 編輯 /var/www/html/cacti/include/config.php

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "xxx3"
/* load up old style plugins here */
$plugins = array();
//$plugins[] = 'thold';

3.5 創建 cacti 系統用戶，設置 graph/log 目錄權限

chown -R apache.apache /var/www/html/
chown -R cacti  /var/www/html/
chown -R apache.apache /var/www/html/cacti/
chown -R cacti /var/www/html/cacti/{rra,log}/
chmod -R 777 /var/www/html/cacti/{rra,log}/

3.6 添加定時任務

crontab -e
*/1 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

4.配置防火牆
4.1 配置 firewalld 防火牆

firewall-cmd --permanent --add-port=3306/tcp
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-port=161/udp
firewall-cmd  --permanent --add-port=162/udp
firewall-cmd --reload

4.2 關閉selinux

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

5.安裝 spine
5.1 下載解壓與 Cacti 相同版本號 Spine 源碼安裝包

cd /usr/local/src
wget http://www.cacti.net/downloads/spine/cacti-spine-1.1.38.tar.gz
tar xf cacti-spine-1.1.38.tar.gz

5.2 源碼編譯安裝 spine

ln -s /usr/lib64/libmysqlclient.so.18.0.0 /usr/lib64/libmysqlclient.so
ntpdate ntp.sjtu.edu.cn
cd cacti-spine-1.1.38
./configure && make && make install

5.3 複製修改配置文件

cp /usr/local/spine/etc/spine.conf.dist /etc/spine.conf
vim /etc/spine.conf
DB_Host                 localhost
DB_Database             cacti
DB_User                 cacti
DB_Pass                 xxx3
DB_Port                 3306
RDB_Host                localhost
RDB_Database            cacti
RDB_User                cacti
RDB_Pass                xxx3
RDB_Port                3306

5.4 測試

/usr/local/spine/bin/spine 

將會出現以下結果
SPINE: Using spine config file [/etc/spine.conf]
SPINE: Version 1.1.38 starting
SPINE: Time: 0.0429 s, Threads: 5, Devices: 0
6.設置重啓、開機啓動相關服務

systemctl restart httpd
systemctl restart mariadb
systemctl restart crond
systemctl restart snmpd
systemctl enable httpd
systemctl enable mariadb
systemctl enable crond
systemctl enable snmpd

7.登錄 Cacti WEB 頁面修改 Cacti 配置
Console -> 設置（Cacti Settings） -> Paths -> 在 Spine Binary File Location 文本框內填入配置文件路徑 /usr/local/spine/bin/spine ，在 Spine Config File Path 框內填入配置文件路徑 /usr/local/spine/etc/spine.conf，點擊保存 （Save）。
Console -> 設置（Cacti Settings） -> Poller -> 在 Poller Type 下拉框中選擇 spine ，點擊保存 （Save）。
8.特別提示
在添加完設備和圖形後，需要重建採集器緩存。
Console –> 系統工具 –> Rebuild Poller Cache

附：
比如說cacti平臺要求更改默認端口號（例改爲10010），且做白名單限制（例只允許IP地址123.123.123.123登錄），相關設置如下
1、改端口號
vim /etc/httpd/conf/httpd.conf
在第137行下修改Listen:80爲Listen:10010，保存退出。
2、防火牆放行10010端口號
vim /etc/sysconfig/iptables
添加防火牆規則
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
重啓防火牆服務
service iptables restart
3、做白名單訪問限制
vim /etc/httpd/conf/httpd.conf
在第318行下， <Directory "/var/www/html">內添加如下內容並保存退出

Order allow,deny
Allow from 123.123.123.123

重啓httpd服務
service httpd restart
