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://tongcheng.blog.51cto.com/6214144/1627590 流水账
http://better.blog.51cto.com/1886029/1199143 源码安装
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 cacti@'%' 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<?phpphpinfo();?>
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
