Nginx 高级配置-第三方模块编译
Nginx 高级配置-第三方模块编译

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
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 ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -s stop
[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 *:22 *:*
LISTEN 0 128 :::22 :::*
[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

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
