nginx别名配置，状态配置，include优化

得益于Nginx的模块化 使用Nginx 配置灵活Nginx有一个include这个 可以为nginx导入外部编写的配置 这样子很灵活下面来看看 具体使用

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/1.6.3
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-1.6.3/)
  -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

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
1、先创建一个目录 mkdir /application/nginx/conf//extra
2、之后备份 cp nginx.conf nginx.conf.pyrene

3、增加include

[root@oldboy conf]# cat nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    include extra/www.conf;
    include extra/bbs.conf;
}
4、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
5、重启

nginx细腻主机别名配置

1、 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：

1、[root@oldboy extra]# vim www.conf 

    server {
        listen       80;
        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;
        }
}
2、[root@oldboy extra]# vim bbs.conf 

    server {
        listen       80;
        server_name  bbs.cnblogs.co cnblog.co;  --》添加别名
        location / {
            root   html/bbs;
            index  index.html index.htm;
        }
    }



2、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
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.8 www.cnblogs.co bbs.cnblogs.co cnblog.co pyrene

3、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/1.1 200 OK
Server: nginx/1.8.1
Date: Sat, 04 Mar 2017 07:06:57 GMT
Content-Type: text/html
Content-Length: 24
Last-Modified: Fri, 03 Mar 2017 18:52:40 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

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：

1、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 80;
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

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

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #nginx vhosts config
    include extra/www.conf;
    include extra/bbs.conf;
    include extra/blog.conf;
    include extra/status.conf;   →这里的包含
}
3、在/etc/hosts里面解析
[root@A conf]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         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
4、在window中解析配置 并且重启
