虚拟机集群

Nginx 1.8.1 部分

下载Nginx源码

curl -o nginx-1.8.1.tar.gz http://nginx.org/download/nginx-1.8.1.tar.gz

解压缩

tar zxvf nginx-1.8.1.tar.gz

安装 PCRE zlib openssl

sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install zlib1g zlib1g.dev
sudo apt-get install openssl libssl-dev

配置

./configure --prefix=/usr/local/mNginx --user=nginx --group=nginx --with-http_ssl_module --
with-http_gzip_static_module

配置结果：

  nginx http scgi temporary files: "scgi_temp"

安装

make
sudo make install

启动

添加nginx用户
sudo useradd nginx
/usr/local/mNginx/sbin/nginx -c /usr/local/mNginx/conf/nginx.conf
-c 指定conf位置，默认情况加载 nginx安装目录/conf/nginx.conf

关闭

ps -ef | grep nginx
从容停止：
kill -QUIT nginx’s-pid
快速停止：
kill -TERM nginx’s-pid
强制停止所有nginx进程：
pkill -9 nginx

重启

平滑重启：
测试配置文件 /usr/local/mNginx/sbin/nginx -t -c
kill -HUP nginx’s pid

PHP 7.0.5部分

下载源码&&解压

curl -o php.tar.gz http://cn2.php.net/distributions/php-7.0.5.tar.gz
tar zxvf php.tar.gz

安装依赖库

sudo apt-get install curl libcurl3 libcurl3-dev
sudo apt-get install libxml2 libxml2-dev 
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libmcrypt-dev libmcrypt4

安装配置

configure 时默认从系统加载依赖，可选从指定目录加载，比如php源码目录下的ext。

./configure --prefix=/usr/local/mPHP --enable-fpm --with-mcrypt --enable-mbstring --with-curl --
with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --with-mhash --enable-zip --with-pcre-regex --w
ith-jpeg-dir

Thank you for using PHP.

复制fpm配置文件

sudo cp /usr/local/mPHP/etc/php-fpm.conf.default /usr/local/mPHP/etc/php-fpm.conf

sudo cp /usr/local/mPHP/etc/php-fpm.d/www.conf.default /usr/local/mPHP/etc/php-fpm.d/www.conf
并且修改user和group为 www

启动

sudo /usr/local/mPHP/sbin/php-fpm

Thinkphp 3.2.3 部分

在/usr/local/mNginx/html下mkdir thp作为项目root目录。
修改nginx.conf,加入重写功能来省略URL中的index.php字样。

user  www www;
worker_processes  2;

error_log  logs/error.log;
error_log  logs/error.log  notice;
error_log  logs/error.log  info;

pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

    server {
        listen       80;
        server_name  nginx-phpapp01.cbd;

        #charset koi8-r;

        access_log  logs/host.access.log  main;

        location / {
            root   html/thp;

            index  index.html index.htm index.php;
        if (!-e $request_filename) {
             rewrite ^/index.php(.*)$ /index.php?s=$1 last;
             rewrite ^(.*)$ /index.php?s=$1 last;
             break;
           }
        }

        error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;

        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #

        location ~ \.php$ {
            root           html/thp;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
            fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
            include        fastcgi_params;
        }
    }
}

Nginx 反向代理转发

nginx-balance.cbd 作为网关，
nginx-phpapp01.cbd 和 nginx-phpapp02.cbd 分别为两个应用服务器。

最简单的架构是app01和app02分别跑不同的模块，根据请求URL分散到各自的服务器上。

nginx.conf修改部分：

          location /Home/Index {
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            proxy_pass http://nginx-phpapp01.cbd;
        }

        location /Home/App2 {
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            proxy_pass http://nginx-phpapp02.cbd;
        }
