01.友盟项目--nginx服务器配置

Nginx实现反向代理

openresty-nginx增强版（现在使用的）

localhost  反向代理到 s102--s104

http://openresty.org/cn/

 

1.windows下

        安装openresty,并修改nginx.conf配置文件

 

nginx.conf配置文件

 

#使用指定用户
#user  root;
#使用的处理器进程数
worker_processes  4;

#错误日志文件
#error_log  logs/error.log;
#日志文件与日志级别
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#存放进程pid
#pid        /tmp/nginx.pid;


events {
    #每个worker最大连接数
    worker_connections  1024;
}


http {
    include       mime.types;
    #default_type  application/json;
    #default_type  application/octet-stream;
    #文件类型:纯文本
    default_type  text/plain;

    #重点:日志格式
    log_format main escape=json $msec#$clientRealIp#$http_client_time#$status#$request_body;
    #log_format  main  escape=json $clientRealIp#$http_client_time#$time_local#$status#$request_body;

    #自定义变量，取得ip串中的第一个ip，也就是用户ip
    map $http_x_forwarded_for  $clientRealIp {
        ~^(?P<firstAddr>[0-9.]+),?.*$    $firstAddr;
    }

    #反向代理服务器不需要存储日志
    access_log  off;

    sendfile        on;
    #tcp_nopush     on;
    underscores_in_headers on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    #反向代理服务器：静态服务器
    upstream nginx_servers{
                server s102:8089 max_fails=2 fail_timeout=2 weight=4;
                server s103:8089 max_fails=2 fail_timeout=2 weight=4;
                server s104:8089 max_fails=2 fail_timeout=2 weight=4;
        }

    #server域配置
    server {
                listen       8089;
                server_name  localhost;
                charset utf-8;
                access_log off;
                location ~* .(png|html|js|css)$ {
                        proxy_pass http://nginx_servers;
                }
                location / {
                        proxy_pass http://nginx_servers;
                }
                proxy_set_header Host $host;
                proxy_set_header remove_user_ip $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

}

2.　linux下

 .下载安装linux下的openresty   在s102-s104安装openresty

 

        你可以在你的 CentOS 系统中添加 openresty 仓库，这样就可以便于未来安装或更新我们的软件包（通过 yum update 命令）。运行下面的命令就可以添加我们的仓库：

        sudo yum install -y yum-utils

        sudo yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo

 

        然后就可以像下面这样安装软件包，比如 openresty：

        sudo yum install -y  openresty

 

nginx.conf配置文件

s102-s104

user  root;
worker_processes  4;

#pid        /tmp/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    #default_type  application/json;
    #default_type  application/octet-stream;
    default_type  text/plain;
    log_format main escape=json $msec#$clientRealIp#$http_client_time#$status#$request_body;
    #log_format  main  escape=json $clientRealIp#$http_client_time#$time_local#$status#$request_body;
    
    map $http_x_forwarded_for  $clientRealIp {                    
        ~^(?P<firstAddr>[0-9.]+),?.*$    $firstAddr;
    }  

    access_log  off;

    sendfile        on;
    #tcp_nopush     on;
    underscores_in_headers on;    

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       8089;
        server_name  s102;

        charset utf-8;

        access_log  /usr/local/openresty/nginx/logs/access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
            error_page      405 =200 $1;
            lua_need_request_body   on;
        content_by_lua  'local s = ngx.var.request_body';
        }

    }

}

  3、安装完之后，文件位置在/usr/local/openresty

  4、启动openresty
        windows启动：nginx

        Linux启动：openresty

 

 5.查看日志

 

 

6.清空日志中数据

[root@s101 /home/centos]# xcall.sh "echo -n > /usr/local/openresty/nginx/logs/access.log
