  第三模块是对nginx 的功能扩展,第三方模块需要在编译安装Nginx 的时候使用参数--add-module=PATH指定路径添加,有的模块是由公司的开发人员针对业务需求定制开发的,有的模块是开源爱好者开发好之后上传到github进行开源的模块,nginx支持第三方模块需要从源码重新编译支持,比如开源的echo模块 https://github.com/openresty/echo-nginx-module.

一.配置echo模块相关功能

1>.查看编译安装nginx的相关参数

[root@node101.yinzhengjie.org.cn ~]# nginx -V
nginx version: nginx/1.14.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/yinzhengjie/softwares/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_modul
e --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module
[root@node101.yinzhengjie.org.cn ~]#

2>.主配置文件(生产环境中不建议更改主配置文件,因为在主配置文件中定义很多server会显得很臃肿,推荐在主配置文件中加载子配置文件将各个server分别放在不同的子配置文件中)

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf/nginx.conf
worker_processes  4;
worker_cpu_affinity 00000001 00000010 00000100 00001000; 

events {
    worker_connections  100000;
    use epoll;
    accept_mutex on;
    multi_accept on; 
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    gzip  on;
    charset utf-8;

    #最大缓存10000个文件,非活动数据超时时长60s
    open_file_cache max=10000 inactive=60s;
    #每间隔60s检查一下缓存数据有效性
    open_file_cache_valid 60s;
    #60秒内至少被命中访问5次才被标记为活动数据
    open_file_cache_min_uses 5;
    #缓存错误信息
    open_file_cache_errors on;

    #隐藏Nginx server版本。
    server_tokens off;

    #当文件大于等于给定大小时,同步(直接)写磁盘,而非写缓存。
    directio 4m;

    #上传文件相关参数
    client_max_body_size 10m;
    client_body_buffer_size 16k;
    client_body_temp_path /yinzhengjie/data/web/nginx/temp 1 2 2;
   

    #IE系列的浏览器禁用长连接,默认就是禁用了IE的长连接功能.
    keepalive_disable msie6;

    #开启长连接后,返回客户端的会话保持时间为60s,单次长连接累计请求达到指定次数请求或65秒就会被断开,后面的60为发送给客户端应答
报文头部中显示的超时时间设置为60s:如不设置客户端将不显示超时时间。    keepalive_timeout  65 60;

    #在一次长连接上所允许请求的资源的最大数量
    keepalive_requests 3;
    
    #导入其他路径的配置文件
    include /yinzhengjie/softwares/nginx/conf.d/*.conf;
}

[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 

3>.编辑echo的相关配置

[root@node101.yinzhengjie.org.cn ~]# cat -n /yinzhengjie/softwares/nginx/conf.d/share.conf 
     1    server {
     2        listen 80;
     3        server_name node101.yinzhengjie.org.cn;
     4    
     5        location / {
     6            root /yinzhengjie/data/web/nginx/static;
     7            index index.html;
     8        }
     9    
    10        location /nginx_status {
    11            stub_status;
    12            allow 172.30.1.108;
    13        deny all;
    14        }
    15    
    16        location /hello {
    17             echo "hello, world!";
    18        }
    19    }
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t      #如下所述,目前的nginx压根就不认识echo指令,因此我们需要停掉nginx服务并编译支持echo指令的相关模块。
nginx: [emerg] unknown directive "echo" in /yinzhengjie/softwares/nginx/conf.d/share.conf:17
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test failed
[root@node101.yinzhengjie.org.cn ~]# 

4>.将echo指令端注释并停止nginx服务,编译支持echo指令的相关模块

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/share.conf 
server {
    listen 80;
    server_name node101.yinzhengjie.org.cn;

    location / {
        root /yinzhengjie/data/web/nginx/static;
        index index.html;
    }

    location /nginx_status {
        stub_status;
        allow 172.30.1.108;
    deny all;
    }

    #location /hello {
    #     echo "hello, world!";
    #}
}
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# ss -ntl

[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# 

二.编译支持echo指令的相关模块

1>.查看支持echo指令的github地址(https://github.com/openresty/echo-nginx-module)

2>.使用git命令将github的项目克隆到本地

[root@node101.yinzhengjie.org.cn ~]# yum -y install git

[root@node101.yinzhengjie.org.cn /usr/local/src]# 
[root@node101.yinzhengjie.org.cn /usr/local/src]# ll echo-nginx-module/

3>.编译安装nginx让其支持echo指令的(参考文档:https://github.com/openresty/echo-nginx-module#installation)

[root@node101.yinzhengjie.org.cn /usr/local/src]# nginx -V          #将配置参数的每一项都复制下来,一会要用来重新编译,这些参数最好都要一模一样。
nginx version: nginx/1.14.2

三.继续配置第三方模块echo指令

1>.修改子配置文件,将之前注释的echo指令代码取消,检查语法通过,说明echo指令的相关模块编译成功

[root@node101.yinzhengjie.org.cn ~]# vim /yinzhengjie/softwares/nginx/conf.d/share.conf 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/share.conf 
server {
    listen 80;
    server_name node101.yinzhengjie.org.cn;

    location / {
        root /yinzhengjie/data/web/nginx/static;
        index index.html;
    }

    location /nginx_status {
        stub_status;
        allow 172.30.1.108;
    deny all;
    }

    location /hello {
         echo "hello, world!";
    }
}
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 

2>.启动nginx

[root@node101.yinzhengjie.org.cn ~]# ss -ntl
State      Recv-Q Send-Q                                         Local Address:Port                                                        Peer Address:Port              
LISTEN     0      128                                                        *:22                                                                     *:*                  
LISTEN     0      128                                                       :::22                                                                    :::*                  
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# ss -ntl
State      Recv-Q Send-Q                                         Local Address:Port                                                        Peer Address:Port              
LISTEN     0      128                                                        *:80                                                                     *:*                  
LISTEN     0      128                                                        *:22                                                                     *:*                  
LISTEN     0      128                                                       :::22                                                                    :::*                  
[root@node101.yinzhengjie.org.cn ~]# 

3>.浏览器访问定义echo指令的相关URL,发现文件被下载下来了(因为我们没有指定相关的MIME类型),如下图所示

4>.继续修改nginx的子配置文件,并指定默认的MIME类型为文本类型

[root@node101.yinzhengjie.org.cn ~]# vim /yinzhengjie/softwares/nginx/conf.d/share.conf 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/share.conf 
server {
    listen 80;
    server_name node101.yinzhengjie.org.cn;

    location / {
        root /yinzhengjie/data/web/nginx/static;
        index index.html;
    }

    location /nginx_status {
        stub_status;
        allow 172.30.1.108;
    deny all;
    }

    location /hello {
         default_type text/html;
         echo "hello, world!";
    }
}
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -s reload
[root@node101.yinzhengjie.org.cn ~]# 

5>.指定默认的MIME类型后,再次访问"http://node101.yinzhengjie.org.cn/hello",如下图所示。

四.在一个location中调用其它location的案例

1>.编辑子配置文件

[root@node101.yinzhengjie.org.cn ~]# vim /yinzhengjie/softwares/nginx/conf.d/share.conf 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/share.conf 
server {
    listen 80;
    server_name node101.yinzhengjie.org.cn;

    location / {
        root /yinzhengjie/data/web/nginx/static;
        index index.html;
    }

    location /nginx_status {
        stub_status;
        allow 172.30.1.108;
    deny all;
    }

    location /main {
    index index.html;
    default_type text/html;
    echo "hello world,main-->";
    echo_reset_timer;
    echo_location /sub1;
    echo_location /sub2;
    echo "took $echo_timer_elapsed sec for total.";
    }

    location /sub1 {
    echo_sleep 1;
    echo sub1;
    }

    location /sub2 {
    echo_sleep 1;
    echo sub2;
     }

}
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 

2>.重新加载配置文件

[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      9297     1  0 18:30 ?        00:00:00 nginx: master process nginx
nginx     9372  9297  0 18:36 ?        00:00:00 nginx: worker process
nginx     9373  9297  0 18:36 ?        00:00:00 nginx: worker process
nginx     9374  9297  0 18:36 ?        00:00:00 nginx: worker process
nginx     9375  9297  0 18:36 ?        00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -s reload
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      9297     1  0 18:30 ?        00:00:00 nginx: master process nginx
nginx     9405  9297  5 18:46 ?        00:00:00 nginx: worker process
nginx     9406  9297  5 18:46 ?        00:00:00 nginx: worker process
nginx     9407  9297  6 18:46 ?        00:00:00 nginx: worker process
nginx     9408  9297  9 18:46 ?        00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]# 

3>.浏览器访问"http://node101.yinzhengjie.org.cn/main",最终结果如下图所示
