ubuntu下nginx+php5环境的部署和centos系统下的部署稍有不同，废话不多说，以下为操作记录：
1）nginx安装
root@ubuntutest01-KVM:~# sudo apt-get update && sudo apt-get upgrade
root@ubuntutest01-KVM:~# sudo apt-get install libpcre3 libpcre3-dev zlib1g-dev libssl-dev build-essential openssl libssl0.9.8 libssl-dev
root@ubuntutest01-KVM:~# wget http://nginx.org/download/nginx-1.8.0.tar.gz
root@ubuntutest01-KVM:~# tar -zxvf nginx-1.8.0.tar.gz
root@ubuntutest01-KVM:~# cd nginx-1.8.0
root@ubuntutest01-KVM:~# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre
root@ubuntutest01-KVM:~# make && make install
2）php5的安装
add-apt-repository 命令是 apt 源的添加，ppa 就是软件对应的源，在官网上可以找到
root@ubuntutest01-KVM:~# sudo add-apt-repository ppa:ondrej/php5-5.6
如果上面命令执行后报错和没有发现命令则执行
root@ubuntutest01-KVM:~# sudo apt-get install Python-software-properties
root@ubuntutest01-KVM:~# sudo apt-get update
root@ubuntutest01-KVM:~# sudo apt-get install php
root@ubuntutest01-KVM:~# php5 -v
安装好php后，在nginx里添加对接php的配置后，访问.php文件会报错502!
这是因为nginx中访问.php文件的请求都交给php-fpm程序处理的，php-fpm监听9000端口
所以还有启动php-fpm程序。
安装php-fpm
root@ubuntutest01-KVM:~# apt-get install php5-fpm php5-gd php5-cli php5-curl php5-mcrypt php5-mysql php5-readline
启动php-fpm
root@ubuntutest01-KVM:~# service php5-fpm start
root@ubuntutest01-KVM:~# ps -ef|grep php5-fpm
root@ubuntutest01-KVM:~# lsof -i:9000
但是发现php5-fpm启动后，9000端口却没有起来！这是为什么？
这是因为php-fpm有两种监听方式：一种是.sock文件方式，另一种是9000端口方式
修改办法：
root@ubuntutest01-KVM:~# vim /etc/php5/fpm/pool.d/www.conf
.....
;listen = /var/run/php5-fpm.sock //注释这行，这是默认的监听方式
listen = 9000 //改为监听9000端口方式
重启php-fpm
root@ubuntutest01-KVM:~# service php5-fpm restart
root@ubuntutest01-KVM:~# lsof -i:9000 //发现9000端口已经起来了
3）nginx+php配置
root@ubuntutest01-KVM:~# vim /usr/local/nginx/conf/nginx.conf //将nginx启动用户改成www-data，确保这个用户存在，不存在就手动创建，保证nginx和php启动用户一致
user www-data;
worker_processes 8;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;pid logs/nginx.pid;events {worker_connections 65535;
}http {include mime.types;default_type application/octet-stream;charset utf-8;log_format main '$http_x_forwarded_for $remote_addr $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_cookie" $host $request_time';sendfile on;tcp_nopush on;tcp_nodelay on;keepalive_timeout 65;fastcgi_connect_timeout 3000;fastcgi_send_timeout 3000;fastcgi_read_timeout 3000;fastcgi_buffer_size 256k;fastcgi_buffers 8 256k;fastcgi_busy_buffers_size 256k;fastcgi_temp_file_write_size 256k;fastcgi_intercept_errors on;client_header_timeout 600s;client_body_timeout 600s;client_max_body_size 100m; client_body_buffer_size 256k; gzip on;gzip_min_length 1k;gzip_buffers 4 16k;gzip_http_version 1.1;gzip_comp_level 9;gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php;gzip_vary on;include vhosts/*.conf;
}
root@ubuntutest01-KVM:~# vim /usr/local/nginx/conf/vhosts/vote.com.conf
server {listen 8080;server_name www.wangshibo.com;access_log /usr/local/nginx/logs/access.log main;error_log /usr/local/nginx/logs/error.log;location / {root /home/www/vote;try_files $uri $uri/ @router;index index.html index.php index.htm;}location /nginx_status {stub_status on;access_log off;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}location @router {rewrite ^.*$ /index.php last;}location ~ \.php$ {root /home/www/vote;fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; //这一行和下面一行要加上，不然访问php文件可能出现空白！fastcgi_param PATH_INFO $fastcgi_script_name;include fastcgi_params;}location ~ ^/(status|ping)$ {include fastcgi_params;fastcgi_pass 127.0.0.1:9000;fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;}
}
测试文件（html文件和php文件）
root@ubuntutest01-KVM:~# vim /home/www/vote/test.html
sdfsadf
12313123
root@ubuntutest01-KVM:~# vim /home/www/vote/test.php
<?php //这一行不能空格，否则访问会有问题 phpinfo(); ?>
修改php-fpm文件（确保/etc/php5/fpm/php-fpm.conf文件中打开了include=/etc/php5/fpm/pool.d/*.conf）
root@ubuntutest01-KVM:~# vim /etc/php5/fpm/pool.d/www.conf
....
user = www-data
group = www-data
....
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
重启nginx和php-rpm
root@ubuntutest01-KVM:~# /usr/local/nginx/sbin/nginx -s reload
root@ubuntutest01-KVM:~# /etc/init.d/php5-fpm restart
最后，验证访问是否正常：
