修改默认MySQL密码，创建cacti数据库，并添加相应权限(MySQL密码默认为空)
[root@test1 ~]# mysql -uroot -p
mysql> set password = password('aa4455**');
mysql> CREATE DATABASE cacti DEFAULT CHARACTER SET utf8;
mysql> GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY 'P@ssw0rd';
mysql> GRANT SELECT ON mysql.time_zone_name TO cacti@localhost IDENTIFIED BY 'P@ssw0rd';
mysql> ALTER DATABASE cacti CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
mysql> flush privileges;
mysql> quit

在my.cnf中添加以下参数（注意最后两个参数如果不添加，后续可能会产生warning），然后重启MySQL
#vim /etc/my.cnf　　#在[mysqld]段中添加如下内容

join_buffer_size = 150M
innodb_buffer_pool_instances = 10
innodb_io_capacity = 5000
innodb_io_capacity_max = 10000
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci

[root@test1 ~]# /etc/init.d/mysql restart
[root@test1 ~]# /etc/init.d/nginx restart

[root@test1 ~]# /usr/local/mysql/bin/mysql_tzinfo_to_sql /usr/share/zoneinfo/|mysql -uroot -paa4455** mysql
下载cacti
[root@test1 ~]# mkdir -p /var/www && cd /var/www/
[root@test1 www]# wget https://www.cacti.net/downloads/cacti-1.2.14.tar.gz
[root@test1 www]# tar -zxvf cacti-1.2.14.tar.gz

修改cacti数据库配置文件
[root@test1 www]# cd cacti/include/
[root@test1 include]# vim config.php
$database_type     = 'mysql';
$database_default = 'cacti';
$database_hostname = 'localhost';
$database_username = 'cacti';
$database_password = 'P@ssw0rd';

导入cacti.sql
[root@test1 include]# mysql -uroot -p aa4455** cacti < /var/www/cacti/cacti.sql
创建日志文件
[root@test1 include]# touch /var/www/cacti/log/{cacti.log,cacti_stderr.log}
创建软链接
[root@test1 include]# ln -sv /usr/local/rrdtool/bin/rrdtool /usr/local/bin/
[root@test1 include]# ln -sv /usr/local/snmp/bin/snmpwalk /usr/local/bin/
[root@test1 include]# ln -sv /usr/local/snmp/bin/snmpget /usr/local/bin/
[root@test1 include]# ln -sv /usr/local/snmp/bin/snmpbulkwalk /usr/local/bin/
[root@test1 include]# ln -sv /usr/local/snmp/bin/snmpgetnext /usr/local/bin/
[root@test1 include]# ln -sv /usr/local/snmp/bin/snmptrap /usr/local/bin/
[root@test1 ~]# cd
修改cacti目录权限
[root@test1 ~]# [root@test1 include]# chown -R www.www /var/www/cacti
修改nginx配置
[root@test1 ~]# cp /usr/local/nginx/conf/vhost/demo.conf /usr/local/nginx/conf/vhost/cacti.conf
[root@test1 ~]# vim /usr/local/nginx/conf/vhost/cacti.conf
server
    {
        server_name 172.16.186.139;             #server_name为本机IP
        index index.html index.htm index.php;
        root /var/www;
....

        include enable-php71.conf;
....
    ....
[root@test1 ~]# nginx -t
[root@test1 ~]# /etc/init.d/nginx reload

spine配置
spine是一个基于C语言的，非常快速的轮询引擎，它是默认的cmd.php的可选替代，如果要使用spine需要单独的设置
[root@test1 ~]# cd /usr/local/spine/etc/
[root@test1 etc]# cp spine.conf.dist spine.conf
[root@test1 etc]# vim spine.conf
注意：该文件中有2处一样的要修改
DB_Host       localhost
DB_Database   cacti
DB_User       cacti
DB_Pass       P@ssw0rd
DB_Port       3306

验证
[root@test1 etc]# /usr/local/spine/bin/spine -C /usr/local/spine/etc/spine.conf
