安装过程

配置基于域名的nginx.conf内容

[root@www ~]# mkdir /application/nginx/conf/extra
[root@www ~]# cd /application/nginx/conf/extra

编辑配置文件

编辑 www.etiantian.org etiantian.org; 网站

[root@www extra]# vim /application/nginx/conf/extra/www.conf
server{
        listen  80;
        server_name     www.etiantian.org etiantian.org;  #配置别名
        location / {
                root    html/www;
                index   index.html index.htm;
        }
        ## gzip buffer=32k flush=5s; 是高并发场景下
        # access_log logs/access_www.log main;
        access_log logs/access_www.log main gzip buffer=32k flush=5s;
}

编辑 bbs 网站

[root@www extra]# vim /application/nginx/conf/extra/bbs.conf

server{
        listen  80;
        server_name     bbs.etiantian.org;
        location / {
                root    html/bbs;
                index   index.html index.htm;
        }
        # access_log logs/access_bbs.log main;
        access_log logs/access_bbs.log main gzip buffer=32k flush=5s;
}

编辑 blog 网站

[root@www extra]# vim /application/nginx/conf/extra/blog.conf
server{
        listen  80;
        server_name     blog.etiantian.org;
        location / {
                root    html/blog;
                index   index.html index.htm;
        }
        # access_log logs/access_blog.log main;
        access_log logs/access_blog.log main gzip buffer=32k flush=5s;
}

编辑 Nginx 状态信息功能

[root@www ~]# vim /application/nginx/conf/extra/status.conf
server{
        listen  80;
        server_name     status.etiantian.org;
        location / {
                stub_status on;
                access_log off;
                allow 192.0.0.0/24; # 容许ip段 只能选一个
                deny all;           # 禁止ip段 只能选一个
        }
}
[root@www extra]# cd ..

编辑主配置文件

[root@www conf]# vim /application/nginx/conf/nginx.conf

worker_processes  1;
error_log       logs/error.log;                                 
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"';
    sendfile        on;
    keepalive_timeout  65;
include extra/www.conf;
include extra/bbs.conf;
include extra/blog.conf;
include extra/status.conf;
}

建立域名对应的站点目录及文件

[root@www conf]# mkdir /application/nginx/html/www /application/nginx/html/bbs /application/nginx/html/blog -p 
[root@www conf]# echo "http://www.etiantian.org" >/application/nginx/html/www/index.html
[root@www conf]# echo "http://bbs.etiantian.org" >/application/nginx/html/bbs/index.html
[root@www conf]# echo "http://blog.etiantian.org" >/application/nginx/html/blog/index.html

检查文件和目录

[root@www conf]# LANG=en
[root@www conf]# tree /application/nginx/html/

检查并从新加载

[root@www conf]# /application/nginx/sbin/nginx -t
[root@www conf]# /application/nginx/sbin/nginx -s reload

在Linux客户端测试

[root@www conf]# echo "192.168.1.70 www.etiantian.org bbs.etiantian.org blog.etiantian.org etiantian.org status.etiantian.org" >> /etc/hosts
[root@www conf]# curl www.etiantian.org
[root@www conf]# curl bbs.etiantian.org
[root@www conf]# curl blog.etiantian.org

在windows 7系统下测试

编辑 C:\Windows\System32\drivers\etc\hosts
追加内容：192.168.1.70 www.etiantian.org bbs.etiantian.org blog.etiantian.org
在dos提示符下检测
ping www.etiantian.org
ping bbs.etiantian.org
ping blog.etiantian.org
在浏览器下直接输入
www.etiantian.org
bbs.etiantian.org
blog.etiantian.orglinux

追加内容：192.168.1.70 www.etiantian.org bbs.etiantian.org blog.etiantian.org etiantian.org status.etiantian.org
此时经过浏览器访问，便可查看状态参数。nginx

nginx 状态信息参数

8.1 server 表示Nginx从启动到如今共处理了xx个链接
8.2 accelits 表示Nginx从启动到如今共建立了xx次握手
8.3 handled requests 表示Nginx从启动到如今共处理了xx次请求
8.4 Reading 为Nginx读取到客户端的Headr信息数
8.5 Writing 为Nginx返回到客户端的Headr信息数
8.6 Waiting 为Nginx已经处理完正在等候下一次请求指令的驻留链接，在开启keep-alive的状况下，这个值等于active-(reading+writing)web

Nginx 访问日志轮询切割

[root@www ~]# vim /server/scripts/cut_nginx_log.sh
#!bin/sh
Dateformat=`date +%Y%m%d`
Basedir="/application/nginx"
Nginxlogdir="$Basedir/logs"
Logname="access_www"
[ -d $Nginxlogdir ]&& cd $Nginxlogdir||exit 1
[ -f ${Logname}.log ]||exit 1
/bin/mv ${Logname}.log ${Dateformat}_${Logname}.log
$Basedir/sbin/nginx -s reload

[root@www ~]# crontab -e

## 添加下面的内容
#cut nginx access log by oldboy
00 00 * * * /bin/sh /server/script/cut_nginx_log.sh >/dev/null 2>&1
