Cacti series of installation chapter Lnmp+cacti+spine (i)

Outline

I. Brief introduction of CACTI

Second, configure Nginx, PHP, MySQL

Third, cacti + spine construction

First, brief

The cacti collects data sources based on SNMP, RRDtool stores data and plots it to users. The data source that SNMP obtains is the. rrd file, which is stored in the RRA directory under the cacti directory.

Second, configure Nginx, PHP, MySQL (ignoring LNMP environment deployment process)

1. Configure Nginx

#在nginx中加入一个server [[email protected]_6.213 cacti-spine-0.8.8h] $vim  /usr/local/nginx/conf/ nginx.conf    server {        listen  8888;        access_log  log/access_catic.log main;         location / {                 index index.html index.php;                 root  /usr/local /cacti/;        }         Location ~.*\. (PHP|PHP5)?$  {                 root   /usr/local/cacti/;                 fastcgi_pass   127.0.0.1:9000;                 fastcgi_index  index.php;                 fastcgi_param  script_ filename   /usr/local/cacti/$fastcgi _script_name;                 include         fastcgi_params;        }         location = /favicon.ico {              log_not_found off;              access_log off;        }        }       #添加完成后, test the configuration file syntax properly [[email protected]_6.213 cacti-spine-0.8.8h]$/usr/local/ Nginx/sbin/nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf  syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf  test is successful# Create cacti log file [[email protected]_6.213 cacti-spine-0.8.8h] $touch  /usr /local/nginx/log/access_cacti.log# change the genus of nginx and subdirectories [[email protected]_6.213 cacti-spine-0.8.8h] $chown  -r nginx.nginx /usr/local/nginx/#启动nginx [[email protected]_6.213 cacti-spine-0.8.8h] $/usr/local/nginx/sbin/nginx# viewing Nginx-Initiated ports [[email protected]_6.213 cacti-spine-0.8.8h] $netstat  - ntlp | grep nginxtcp        0       0 0.0.0.0:80                   0.0.0.0:*                    LISTEN      29641/nginx          tcp        0      0  0.0.0.0:8888                 0.0.0.0:*                    listen      29641/nginx

2. Configure PHP:

#更改php. ini time zone [[[email protected]_6.213 cacti-spine-0.8.8h] $vim  /etc/php.inidate.timezone = asia/shanghai# changing the PHP-FPM group [[email protected]_6.213 conf] $vim  /etc/php-fpm.d/www.confuser  = nginxgroup = nginx# start php-fpm and view its port status [[Email protected]_6.213 conf] $service  php-fpm startStarting php-fpm:                                            [  OK   ][[EMAIL PROTECTED]_6.213 CONF] $netstat  -ntlp | grep phptcp         0      0 127.0.0.1:9000               0.0.0.0:*                    listen      3773/php-fpm# Create a new Session directory and change the directory genera Group and permissions (defined session path in/etc/php-fpm.d/www.conf) [[Email protected]_6.213 local] $mkdir  -p /var/lib/php/session[[email protected]_6.213 local] $chown  nginx.nginx /var/ Lib/php/session[[email protected]_6.213 local] $chmod  -r 770 /var/lib/php/session

3. Create and import cacti database and user password authorization

Mysql> CREATE database cacti;mysql> use cacti;mysql> \. /usr/local/cacti/cacti.sqlmysql> create user ' cactiuser ' @ ' 192.168.%.% ' identified by ' CACTIPASSWD ';mysql> grant All on cacti.* to ' cactiuser ' @ ' 192.168.%.% ' identified by ' cactipasswd ';mysql> flush privileges;

#6. Web interface Configuration Chapter #a. Open the browser, enter the cacti server IP address and port (default 80, no input), enter the installation interface, for example, click Next:
