ubuntu下nginx+php5的部署

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;

    include vhosts/*.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：
