Cacti在nginx上搭建步骤

Cacti on nginx + php-fpm

系统环境:

centos 5.3  32位     #（安装好所有的开发工具）

软件版本:

Cacti-0.8.7e

Mysql-5.1.38

php-5.2.10

php-5.2.10-fpm-0.5.13.diff.gz

rrdtool-1.2.28

nginx-0.8.15

rpmforge-release.i386

rpmforge

yum -y install rpmforge-release           #安装yum的rpmforge仓库

Mysql-5.1.38

cd /home

wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.38.tar.gz/from/http://mysql.isu.edu.tw/

tar -xvf mysql-5.1.38.tar.gz              #从mysql官网下载源码包,解压

进入mysql解压目录

cd /home/mysql-5.1.38

下为mysql 官网提供的编译配置

       -fno-exceptions -fno-rtti" ./configure        --prefix=/usr/local/mysql --enable-assembler        --with-mysqld-ldflags=-all-static建议移除最后1排;CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors        -fno-exceptions -fno-rtti" ./configure        --prefix=/usr/local/mysql --enable-assembler Make

Make install              #这样mysql就被安装在 /usr/local/mysql 之下

====================================================================

configure: error: No curses/termcap library found 的错误解决方法

在编译Mysql时

./configure –prefix=DIR

configure: error: No curses/termcap library found

说明 curses/termcap 库没有安装    apt-cache search curses | grep lib

安装 libncurses5-dev ，然后重新运行配置

apt-get install libncurses5-dev

上边的具体细节还希望先yum list | grep ncurses下看看。

yum install ncurses-dev

没有安装gcc的也要yum install gcc下先，不然不会编译。

 #启动Nginx服务

=====================================================================

nginx配置httpd服务遇到问题No input file specified的解决

首先php.ini的配置中

cgi.fix_pathinfo=1

doc_root=

doc_root曾经被我设置过一个路径，结果php老提示“No input file specified.”，只有一个虚机好使。改掉后就正常了。

nginx中的配置有些麻烦

fastcgi_pass 127.0.0.1:1234;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

每个虚机要根据自己不通的虚机设置不不同的目录，要保证这个路径正确。

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;不能在fastcgi_pass 127.0.0.1:1234;的前面。

跟我的情况很类似 我也尝试改了一下第二个vhost的文件中php部分：

# .php

location ~ .*.(php|php5)?$
{
    #fastcgi_pass unix:/tmp/php-cgi.sock;

    fastcgi_pass 127.0.0.1:9000;

    fastcgi_param  SCRIPT_FILENAME  /data/htdocs/域名/$fastcgi_script_name; 确实是要与第一个域名区分开来

    fastcgi_index index.php;

    #include fcgi.conf;

}

=====================================================================

nginx时常被php的“No input file specified.

首先php.ini的配置中

cgi.fix_pathinfo=1

doc_root=

doc_root曾经被我设置过一个路径，结果php老提示“No input file specified.”，只有一个虚机好使。改掉后就正常了。

nginx中的配置有些麻烦

fastcgi_pass 127.0.0.1:1234;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

每个虚机要根据自己不通的虚机设置不能的目录，要保证这个路径正确。

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;不能在fastcgi_pass 127.0.0.1:1234;的前面。

记得修改了php.ini要重启fastcgi服务。

其实都是因为粗心造成的，本来很简单，写出来也给自己提个醒

=====================================================================

RRDTool(两种方法)：

1.软件包安装：

先yum安装所要的库文件：

yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel

然后下载rrdtool包，安装：

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz

tar -zxvf rrdtool-1.3.1.tar.gz

./configure --prefix=/usr/local/rrdtool

make

make install

2. 另一种yum安装

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

rpm -ivh rpmforge-release-0.3.6-1.el5.rf.i386.rpm
yum -y install rrdtool*

配置开机自动启动Nginx + PHP

vi /etc/rc.local

在末尾增加以下内容：

ulimit -SHn 51200

/usr/local/webserver/php/sbin/php-fpm start

/usr/local/webserver/nginx/sbin/nginx

重启服务器

WEB界面配置Cacti

之后就可通过访问服务器ip 进去cacti界面

一路默认配置进入密码验证界面

Username:admin

Password:admin

 

进入Cacti界面

单击setting选项

在General选项卡里将RRDTool Utility Version那一项改为RRDTool 1.3.X

在Ppaths选项卡里将所有带红色的路径都全设置一遍，直到没有红色为止

我的是这两项：

 

PHP Binary Path→/usr/local/php5/bin/phpRRDTool Binary Path→/usr/local/rrdtool/bin/rrdtool好了，点击保存就可以体验自己的千辛万苦做出来的东东了。
