centos 6.5 Nginx安装

安装nginx

版本: nginx-1.12.1 稳定版
系统: centos 6.5

一、准备事项

（1） 因为nginx需要访问80端口所以请先关闭或者开放防火墙端口，和selinux。
参考命令
关闭防火墙：
[root@local ~]# iptables -I INPUT -p tcp --dport 80 -j ACCEPT
[root@local ~]# service iptables save
关闭selinux：
[root@local ~]# setenforce 0
[root@local ~]# vim /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled

二，安装

1、环境准备：先安装准备环境
yum install gcc gcc-c++ automake pcre pcre-devel zlip zlib-devel openssl openssl-devel 

2、下载nginx 安装包：  官网地址：http://nginx.org/

3、解压安装包:

4、编译nginx：make
[root@Server1 nginx-1.8.1]# ./configure  --prefix=/usr/local/nginx  --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/var/log/nginx/error.log  --http-log-path=/var/log/nginx/access.log  --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock  --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre

5、生成脚本及配置文件：make

6、安装：make install

7、启动：
将监听端口改为8090，避免80端口冲突：

三,注意

Ubuntu安装时

解决依赖包openssl安装，命令：
[cpp] view plain copy
  1. sudo apt-get install openssl libssl-dev  

解决依赖包pcre安装，命令：
[cpp] view plain copy
  1. sudo apt-get install libpcre3 libpcre3-dev  

解决依赖包zlib安装，命令：
[cpp] view plain copy
  1. sudo apt-get install zlib1g-dev  

nginx负载均衡简单配置

准备三台虚拟机来做这个实验：

192.168.232.132 web服务器
192.168.232.133 web服务器
192.168.232.134 负载均衡服务器

1.yum安装nginx

yum install nginx

2.启动nginx

chkconfig nginx on
service nginx start

3.配置负载均衡服务器

user  nginx;  
worker_processes  1;  
 
error_log  /var/log/nginx/error.log warn;  
pid        /var/run/nginx.pid;  
events {  
worker_connections  1024;  
}  
  
http {  
    include       /etc/nginx/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  /var/log/nginx/access.log  main;  
    sendfile        on;  
    #tcp_nopush     on;    
    keepalive_timeout  65;  

    #gzip  on;  
    upstream test.miaohr.com {  
        server 192.168.232.132:80;  
        server 192.168.232.133:80;  
    }  
      
    server {     
        listen       80;     
        server_name  test.miaohr.com;     
        charset utf-8;     
        location / {     
            root   html;     
            index  index.html index.htm;     
            proxy_pass        http://test.miaohr.com;     
            proxy_set_header  X-Real-IP  $remote_addr;     
            client_max_body_size  100m;  
        }     
    
    
        location ~ ^/(WEB-INF)/ {      
        deny all;      
        }      
    
        error_page   500 502 503 504  /50x.html;     
        location = /50x.html {     
            root   /var/www/html/;     
        }     
    }     
}  

Nginx文件压缩

图片压缩基本没效果
