cacti nagios 从apache迁移到nginx

nics

　　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;
index index.php index.html;
root /var/www/nagios3/htdocs;
auth_basic "Nagios Login pain";
auth_basic_user_file /etc/nginx/htpasswd.users;
#stylesheets没有这块，不能正常显示
location /stylesheets/ {
alias /etc/nagios3/stylesheets/;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include /etc/nginx/fastcgi_params;
}
location ~ \.cgi$ {
root /usr/lib/cgi-bin/nagios3;
rewrite ^/cgi-bin/nagios3/(.*)$ /$1 break;#此处必须用break。使用last或不用都会出现403错误
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 REMOTE_USER $remote_user;
fastcgi_param   QUERY_STRING            $query_string;
fastcgi_param   REQUEST_METHOD          $request_method;
fastcgi_param   CONTENT_TYPE            $content_type;
fastcgi_param   CONTENT_LENGTH          $content_length;
fastcgi_param   SCRIPT_FILENAME         $request_filename;
fastcgi_param   SCRIPT_NAME             $fastcgi_script_name;
fastcgi_param   REQUEST_URI             $request_uri;
fastcgi_param   DOCUMENT_URI            $document_uri;
fastcgi_param   DOCUMENT_ROOT           $document_root;
fastcgi_param   SERVER_PROTOCOL         $server_protocol;
fastcgi_param   GATEWAY_INTERFACE       CGI/1.1;
fastcgi_param   SERVER_SOFTWARE         nginx/$nginx_version;
fastcgi_param   REMOTE_ADDR             $remote_addr;
fastcgi_param   REMOTE_PORT             $remote_port;
fastcgi_param   SERVER_ADDR             $server_addr;
fastcgi_param   SERVER_PORT             $server_port;
fastcgi_param   SERVER_NAME             $server_name;
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);
}
