cacti nagios 从apache迁移到nginx

1.编译php5.4，加载相应模块

mysql模块编译时需要注意，--withmysql=DIR      Include MySQL support.  DIR is the MySQL base mysqlnd the MySQL native driver will be used

DIR是根目录，可以用find / -name mysql.h查找  ，/usr/include/mysql/mysql.h，只需/usr即可




./configure --prefix=/usr/local/php5 --enable-fpm --with－fpm-user=www-data --with-fpm-group=www-data --enable-fastcgi --with-mysql=/usr --withmysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr
make
make install

   编译好后发现少了一些模块，不过可以手动编译单个模块。

   gd模块编译

cd ext/gd
/usr/local/php5/bin/phpize
./configure --with-php-config=/usr/local/php5/bin/php-config --with-freetype-dir=/usr/local/include/freetype2
make
make install

    snmp模块编译

cd ext/snmp
/usr/local/php5/bin/phpize
./configure --with-php-config=/usr/local/php5/bin/php-config
make
make install

       编辑 /usr/local/php5/lib/php.ini，在最下面添加

extension =snmp.so
extension=gd.so
extension=mysql.so
extension=mysqli.so
extension=pdo_mysql.so

2. 安装fcgiwrap

apt-get install fcgiwrap

   或者源码安装

autoreconf
./configure
make
make install

3.nginx配置

   cacti.conf

server {
        listen 80;
        server_name cacti.test.com;
        index index.php index.html;
        root /var/www/cacti/site;
        charset utf-8; #weathermap插件正常显示中文
        location ~ \.php$
        {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                include /etc/nginx/fastcgi_params;
        }
                                                                                                                                                                                                                                                                                  
        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
                expires 30d;
                access_log off;
        }
                                                                                                                                                                                                                                                                                  
        location ~ .*\.(js|css)?$
        {
                expires 1h;
                access_log off;
        }
        #weathermap编辑页面，添加验证
        location /plugins/weathermap/editor.php
        {
                fastcgi_pass 127.0.0.1:9000;
                include /etc/nginx/fastcgi_params;
                auth_basic "Login:";
                auth_basic_user_file /etc/nagios3/htpasswd.users;
        }
                                                                                                                                                                                                                                                                                   
}

   nagios.conf

server {
        listen 80;
        server_name nagios.test.com;

        }

                fastcgi_pass  unix:/var/run/fcgiwrap.socket; #sudo apt-get install fcgiwrap安装
                fastcgi_index index.cgi;
                #fastcgi_param SCRIPT_FILENAME /usr/lib/cgi-bin/nagios3/$1;#也可以这样写
                fastcgi_param SCRIPT_FILENAME /usr/lib/cgi-bin/nagios3$fastcgi_script_name;#cgi脚本位置，可以用$document_root代替
                fastcgi_param AUTH_USER $remote_user;

                fastcgi_param   CONTENT_TYPE            $content_type;
                fastcgi_param   CONTENT_LENGTH          $content_length;
                fastcgi_param   SCRIPT_FILENAME         $request_filename;

                fastcgi_param   REDIRECT_STATUS         200;
        }
}

4.运行

/etc/init.d/fcgiwrap start
/usr/local/php5/sbin/php-fpm
nginx

5.cacti0.87g 使用php5.4出现错误的解决方法,错误内容为：PHP message: PHP Fatal error:  Call to undefined function session_unregister() in /var/www/cacti/site/lib/functions.php on line 410,修改functions.php 410行附近内容为：

/* kill_session_var - kills a session variable using two methods -- session_unregister() and unset() */
function kill_session_var($var_name) {
        /* register_global = off: reset local settings cache so the user sees the new settings */
        /*session_unregister($var_name);*/
        /* register_global = on: reset local settings cache so the user sees the new settings */
        /*unset($_SESSION[$var_name]);*/
        unset($var_name);
}
