nginx别名配置，状态配置，include优化

一、nginx帮助参数

下面是关于/application/nginx/sbin/nginx 的参数帮助
[root@A conf]# /application/nginx/sbin/nginx -h
nginx version: nginx/1.6.
Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /application/nginx-1.6./)
  -c filename   : set configuration file (default: conf/nginx.conf)
  -g directives : set global directives out of configuration file

重启要学脚本，检查api端口，如果没问题就重启，如果有问题恢复到原来的模式

二、利用include功能优化nginx的配置文件

由于nginx主配置文件工作的时候会有很多虚拟主机维护不方便，因此会做出下面的
、先创建一个目录  mkdir  /application/nginx/conf//extra
、之后备份 cp nginx.conf  nginx.conf.pyrene

、增加include
[root@oldboy conf]# cat nginx.conf
worker_processes  ;
events {
    worker_connections  ;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  ;
    include extra/www.conf;
    include extra/bbs.conf;
}
、配置server标签
[root@oldboy conf]# cp nginx.conf.pyrene extra/a
[root@oldboy conf]# cd extra/
[root@oldboy extra]# ls
a
[root@oldboy extra]# sed -n "10,17p" a>www.conf
[root@oldboy extra]# sed -n "18,25p" a>bbs.conf
、重启

三、nginx细腻主机别名配置

 、    虚拟主机别名介绍及配置
     所谓虚拟主机别名，就是为虚拟主机设置出了主域名意外的一个域名
 方法：直接在配置文件中域名哪里直接添加一个新的域名，然后域名和域名之间要用空格隔开
 如：
 、[root@oldboy extra]# vim www.conf 

     server {
         listen       ;
         server_name  www.cnblogs.co pyrene;   --》添加别名   别名之间空格就可以
         location / {
             root   html/www;
             index  index.html index.htm;
         }
 }
 、[root@oldboy extra]# vim bbs.conf 

     server {
         listen       ;
         server_name  bbs.cnblogs.co cnblog.co;  --》添加别名
         location / {
             root   html/bbs;
             index  index.html index.htm;
         }
     }

 、把域名写道/etc/hosts解析

 [root@A conf]# vim /etc/hosts

 [root@oldboy extra]# cat /etc/hosts
 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::         localhost localhost.localdomain localhost6 localhost6.localdomain6
 10.0.0.8 www.cnblogs.co bbs.cnblogs.co cnblog.co pyrene

 、然后检查语法，重启关闭防火墙，curl 查看就可以
 [root@oldboy extra]# curl -I pyrene
 HTTP/1.1  OK
 Server: nginx/1.8.
 Date: Sat,  Mar  :: GMT
 Content-Type: text/html
 Content-Length:
 Last-Modified: Fri,  Mar  :: GMT
 Connection: keep-alive
 ETag: "58b9bb78-18"
 Accept-Ranges: bytes
 别名除了可以方便搜索之外，监控服务器里面监控别名，可以很好的判断每一台机器是否正常

四、Nginx状态信息配置

 编译的时候制定了一个状态模块  —with-http_stub_status_module 显示nginx当先的状态
 配置如下：

 、选择虚拟主机的方式增加了一个server标签到/application/nginx/conf/extra/status.conf里面，起名status.etiantian.org
 cat >>/application/nginx/conf/extra/status.conf<<EOF
 ##status
 server{
 listen ;
 server_name status.cnblogs.co;
 location / {
   stub_status on;
   access_log  off;
 }
 }
 EOF

 server_name status. status.cnblog.co;    →这里添加的域名  标签

 、需要包含,include
 [root@A conf]# vim nginx.conf

 worker_processes  ;
 events {
     worker_connections  ;
 }
 http {
     include       mime.types;
     default_type  application/octet-stream;
     sendfile        on;
     keepalive_timeout  ;
     #nginx vhosts config
     include extra/www.conf;
     include extra/bbs.conf;
     include extra/blog.conf;
     include extra/status.conf;   →这里的包含
 }
 、在/etc/hosts里面解析
 [root@A conf]# vim /etc/hosts
 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::         localhost localhost.localdomain localhost6 localhost6.localdomain6
 10.0.0.8 www.cnblogs.co bbs.cnblogs.co cnblog.co pyrene. status.cnblog.co  →这里就是解析
 、在window中解析配置 并且重启nginx

5、查看

浏览器中出现

[root@A conf]# curl status.cnblog.co

Active connections: 1                         →查看连接数

server accepts handled requests

16 16 16

Reading: 0 Writing: 1 Waiting: 0

上面的详细讲解

Active connections:2872

#<==表示Nginx 正处理的活动连接数 2872个
