网上教程很多,但是nginx不太多,下面安装时候主要参考的篇文章:
http://54im.com/linux/linux-cacti-cn-install.html
http://www.tecmint.com/install-cacti-network-monitoring-on-rhel-centos-6-3-5-8-and-fedora-17-12/ 主要
用到的服务有mysql nginx net-snmp php acati php-fpm
还有各种安装包,安装的环境是 Centos6.5
我这边一般的mysql nginx都是安装好的,主要是php 安装不熟悉
net-snmp, rrdtool 安装
# yum install rrdtool net-snmp net-snmp-libs net-snmp-utils
php 以及依赖的包
# yum install php php-mysql php-snmp php-xml php-gd php-pear php-common php-devel php-mbstring php-cli php-fpm
mysql 用户和数据库建立
mysql>create database cacti default character set utf8;
mysql>GRANT SELECT, INSERT, UPDATE, DELETE, INDEX, ALTER, CREATE, LOCK TABLES, CREATE TEMPORARY TABLES, DROP, REFERENCES ON cacti.* TO [email protected]‘%‘ IDENTIFIED BY ‘cacti#erya‘;
mysql>flush privileges;
安装cacti
# mkdir /www
# cd /www/
# wget -c http://www.cacti.net/downloads/cacti-0.8.8c.tar.gz
# tar zxvf cacti-0.8.8c.tar.gz
# mv cacti-0.8.8c cacti
# mysql -ucacti -pcacti#erya -Dcacti < cacti/cacti.sql
修改数据库配置
# vim /www/cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti#erya";
$database_port = "3306";
$database_ssl = false;
还有要改时区,否则画出来的图时间轴不对。还是php.ini设置的好
date.timezone = Asia/Shanghai
添加nginx web用户和权限,这里没做,不过可以后来修改
还有设置开机启动等
添加nginx配置,重启nginx php-fpm
等
server {
listen 8080;
server_name localhost;
root /www/cacti;
location /cacti {
alias /www/cacti;
index index.php;
}
location ~ ^/cacti.+\.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^/cacti(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME /www/cacti/$fastcgi_script_name;
include fastcgi.conf;
}
}
没搞明白这个配置,但是可以使用
添加定时任务
#vim /etc/cron.d/cacti
*/5 * * * * /usr/bin/php /www/cacti/poller.php > /dev/null 2>&1
到这里基本就安装完毕了。
测试nginx ,php是否好用,这里用fastcgi吧,只是界面
[[email protected] html]# cat index.php
<?php
phpinfo();
?>
这里的问题就是php怎么启动,nginx配置fastcgi很容易,但是php容器需要安装和重新编译
继续安装
# yum install php-fpm
这是一个服务,还需配置
主配置文件 /etc/php-fpm.conf 子配置文件在 php-fpm.d/
# /etc/init.d/php-fpm start
正在启动 php-fpm: [确定]
nginx配置文件
server {
listen 8080;
server_name localhost;
root html;
index index.php;
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
location ~ \.php$ {
try_files $uri =404;
include fastcgi.conf;
fastcgi_pass 127.0.0.1:9000;
}
}
然后访问 http://192.168.31.206:8080/
可以看到php信息,不太懂怎么找到php文件路径的
错误
如果出现了下面的错误
2015/05/22 16:06:33 [error] 30521#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 523800 bytes) in /home/www/cacti/lib/adodb/adodb.inc.php on line 833" while reading response header from upstream, client: 103.254.64.163, server: localhost, request: "GET /cacti/index.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "124.88.61.42:8890"
可能是没有初始化数据库的原因
