1、下载安装包 ：wgethttp://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

安装 rpm -ivhnginx-release-centos-6-0.el6.ngx.noarch.rpm

or

yum install nginx

目录：/usr/sbin/nginx  /etc/nginx/conf.d

启动 /usr/sbin/nginx 

停止 pkill -9 nginx

加载配置: /usr/sbin/nginx -s reload

配置所在目录为“/etc/nginx/”，其中默认含有两个配置文件，一个是Nginx.conf，另一个是conf.d/default.conf。Nginx实际首先访问到Nginx.conf，而conf.d/default.conf是Nginx.conf配置文件中引用的配置文件。

配置多个域名:同一个工程下面一个主域名，一个二级域名

upstream website {
    server 192.168.10.158:28080 weight=1;
}


server {
    listen 80;
    server_name tool.com;

    location = / {
        rewrite /  http://tool.com/tools/jsp/index.jsp;   #不加这个访问二级域名的时候跳转到一级域名主页
}



    location ~  / {
        proxy_pass http://website;
        proxy_set_header Host $host:80;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_send_timeout 90;
        proxy_connect_timeout 90;
        proxy_read_timeout 90;
        proxy_ignore_client_abort on;    
} 
}

server {
    listen       80;
    server_name  testxmf.com;
    #charset koi8-r;
    access_log  /etc/nginx/conf.d/log/host.access.log  main;
    location ~ / {
	proxy_pass http://website;
	rewrite /tools/(.+)  http://tool.com/tools/$1;    #一级域名首页上二级域名标签点击之后跳转到二级域名首页
	proxy_set_header Host $host:80;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_send_timeout 90;
        proxy_connect_timeout 90;
        proxy_read_timeout 90;
        proxy_ignore_client_abort on;    
}


    #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   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

nginx 的使用
