Nginx的配置和使用-创新互联
概述
Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器,同时也提供了IMAP/POP3/SMTP服务。Nginx是由伊戈尔·赛索耶夫为俄罗斯访问量第二的Rambler.ru站点(俄文:Рамблер)开发的,第一个公开版本0.1.0发布于2004年10月4日。
目前创新互联已为1000+的企业提供了网站建设、域名、雅安服务器托管、网站托管维护、企业网站设计、和硕网站维护等服务,公司将坚持客户导向、应用为本的策略,正道将秉承"和谐、参与、激情"的文化,与客户和合作伙伴齐心协力一起成长,共同发展。其将源代码以类BSD许可证的形式发布,因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日,nginx 1.0.4发布。
Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器,在BSD-like 协议下发行。其特点是占有内存少,并发能力强,事实上nginx的并发能力在同类型的网页服务器中表现较好
Nginx优点
Nginx 可以在大多数 UnixLinux OS 上编译运行,并有 Windows 移植版。 Nginx 的1.4.0稳定版已经于2013年4月24日发布,一般情况下,对于新建站点,建议使用最新稳定版作为生产版本,已有站点的升级急迫性不高。
Nginx 的源代码使用 2-clause BSD-like license。
Nginx 是一个很强大的高性能Web和反向代理服务,它具有很多非常优越的特性:
在连接高并发的情况下,Nginx是Apache服务不错的替代品:Nginx在美国是做虚拟主机生意的老板们经常选择的软件平台之一。能够支持高达 50,000 个并发连接数的响应,感谢Nginx为我们选择了 epoll and kqueue作为开发模型。
nginx状态页
在编译的时候需要添加--with-http_stub_status_module参数
配置案例:
[root@CentOS7-01 ~]#cat /apps/nginx/conf/vhosts/pc.conf
server {
listen 80;
server_name www.hechunping.tech;
location /nginx_status {
stub_status;
allow 192.168.7.0/24;
allow 127.0.0.1;
deny all;
}
}
[root@CentOS7-01 ~]#systemctl reload nginx
访问测试
[root@CentOS7-01 ~]#curl www.hechunping.tech/nginx_status
Active connections: 1
server accepts handled requests
32 32 36 #这三个数字分别对应accepts,handled,requests三个值
Reading: 0 Writing: 1 Waiting: 0
相关解释:
Active connections: 当前处于活动状态的客户端连接数,包括连接等待空闲连接数。
accepts: 统计总值,Nginx⾃启动后已经接受的客户端请求的总数。
handled: 统计总值,Nginx⾃启动后已经处理完成的客户端请求的总数,通常等于accepts,除⾮有因worker_connections限制等被拒绝的连接。
requests:统计总值,Nginx⾃启动后客户端发来的总的请求数。
Reading: 当前状态,正在读取客户端请求报⽂⾸部的连接的连接数。
Writing: 当前状态,正在向客户端发送响应报⽂过程中的连接数。
Waiting: 当前状态,正在等待客户端发出请求的空闲连接数,开启 keep-alive的情况下,这个值等于 active – (reading+writing)。
nginx编译的时候添加第三方模块
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

nginx变量使用
nginx的变量可以在配置⽂件中引⽤,作为功能判断或者⽇志等场景使⽤,变量可以分为内置变量和⾃定义变量,
内置变量是由nginx模块⾃带,通过变量可以获取到众多的与客⼾端访问相关的值。
1 内置变量
可以通过上面的echo模块输出,下面的变量都是参照如下配置文件
[root@CentOS7-01 nginx-1.16.1]#cat /apps/nginx/conf/vhosts/pc.conf

location /pc {
set $name $server_name;
echo $name;
set $my_port $server_port;
echo $my_port;
}
}
[root@CentOS7-01 ~]#!s
systemctl restart nginx
访问测试
[root@CentOS7-01 ~]#curl http://www.hechunping.tech/pc
www.hechunping.tech

nginx自定义访问日志
访问⽇志是记录客户端即⽤户的具体请求内容信息,全局配置模块中的error_log是记录nginx服务器运⾏时的⽇志
保存路径和记录⽇志的level,因此有着本质的区别,⽽且Nginx的错误⽇志⼀般只有⼀个,但是访问⽇志可以在不
同server中定义多个,定义⼀个⽇志需要使⽤access_log指定⽇志的保存路径,使⽤log_format指定⽇志的格式,
格式中定义要保存的具体⽇志内容。
1 自定义默认格式日志
如果是要保留⽇志的原格式,只是添加相应的⽇志内容,则配置如下:
log_format www.hechunping.tech '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"'
'$server_name:$server_port';
access_log /data/nginx/logs/www.hechunping.tech/access.log www.hechunping.tech;
[root@CentOS7-01 ~]#nginx -t
nginx: the configuration file /apps/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /apps/nginx/conf/nginx.conf test is successful
[root@CentOS7-01 ~]#systemctl reload nginx
[root@CentOS7-01 ~]#tail -f /data/nginx/logs/www.hechunping.tech/access.log
192.168.7.1 - - [05/Jan/2020:14:58:47 +0800] "GET /pc/ HTTP/1.1" 200 7 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36" "-"www.hechunping.tech:80
2 自定义json格式日志
Nginx 的默认访问⽇志记录内容相对⽐较单⼀,默认的格式也不⽅便后期做⽇志统计分析,⽣产环境中通常将nginx⽇志转换为json⽇志,然后配合使⽤ELK做⽇志收集-统计-分析。
log_format access_json '{"@timestamp":"$time_iso8601",'
'"host":"$server_addr",'
'"clientip":"$remote_addr",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"upstreamtime":"$upstream_response_time",'
'"upstreamhost":"$upstream_addr",'
'"http_host":"$host",'
'"uri":"$uri",'
'"domain":"$host",'
'"xff":"$http_x_forwarded_for",'
'"referer":"$http_referer",'
'"tcp_xff":"$proxy_protocol_addr",'
'"http_user_agent":"$http_user_agent",'
'"status":"$status"}';
access_log /data/nginx/logs/www.hechunping.tech/access.log access_json;
[root@CentOS7-01 ~]#tail -f /data/nginx/logs/www.hechunping.tech/access.log
{"@timestamp":"2020-01-05T15:04:16+08:00","host":"192.168.7.71","clientip":"192.168.7.1","size":7,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"www.hechunping.tech","uri":"/pc/index.html","domain":"www.hechunping.tech","xff":"-","referer":"-","tcp_xff":"","http_user_agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36","status":"200"}
3 用Python统计json格式的访问日志
[root@CentOS7-01 ~]#cat nginx_json.py
#!/usr/bin/env python
#coding:utf-8
status_200 = []
status_404 = []
with open("access_json.log") as f:
for line in f.readlines():
line = eval(line)
if line.get("status") == "200":
status_200.append(line.get)
elif line.get("status") == "404":
status_404.append(line.get)
else:
print("状态码 ERROR")
f.close()
print "状态码为200的有-->:",len(status_200)
print "状态码为404的有-->:",len(status_404)
[root@CentOS7-01 ~]#python nginx_json.py
...
状态码 ERROR
状态码为200的有-->: 403428
状态码为404的有-->: 125712
nginx压缩功能
Nginx⽀持对指定类型的⽂件进⾏压缩然后再传输给客⼾端,⽽且压缩还可以设置压缩⽐例,压缩后的⽂件⼤⼩将⽐源⽂件显著变⼩,这样有助于降低出⼝带宽的利⽤率,降低企业的IT⽀出,不过会占⽤相应的CPU资源。
Nginx对⽂件的压缩功能是依赖于模块ngx_http_gzip_module,官⽅⽂档: https://nginx.org/en/docs/http/ngx_http_gzip_module.html, 配置指令如下:
gzip on | off; #启⽤或禁⽤gzip压缩,默认关闭
gzip_comp_level level; #压缩⽐由低到⾼从1到9,默认为1
gzip_disable "MSIE [1-6]\."; #禁⽤IE6 gzip功能
gzip_min_length 1k; #gzip压缩的最⼩⽂件,⼩于设置值的⽂件将不会压缩
gzip_http_version 1.0 | 1.1; #启⽤压缩功能时,协议的最⼩版本,默认HTTP/1.1
gzip_buffers number size; #指定Nginx服务需要向服务器申请的缓存空间的个数*⼤⼩,默认32 4k|16 8k;
gzip_types mime-type ...; #指明仅对哪些类型的资源执⾏压缩操作;默认为gzip_types text/html,不⽤显⽰指定,否则出错
gzip_vary on | off; #如果启⽤压缩,是否在响应报⽂⾸部插⼊"Vary: Accept-Encoding"
配置案例
gzip on;
gzip_comp_level 5;
gzip_min_length 1k; gzip_types text/plain application/javascript application/x-javascript text/cssapplication/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
gzip_vary on;
[root@CentOS7-01 ~]#cat /apps/nginx/conf/vhosts/pc.conf
server {
listen 80;
server_name www.hechunping.tech;
location /pc {
root html;
}
}
[root@CentOS7-01 ~]#ll /apps/nginx/html/pc/test.html -h
-rw-r--r-- 1 nginx nginx 1.7M Jan 5 16:01 /apps/nginx/html/pc/test.html #使用该文件进行压缩测试
访问测试,压缩后的大小
https功能
1 ssl配置参数
nginx的https功能基于模块ngx_http_ssl_module实现,因此如果是编译安装的nginx要使⽤参数--with-http_ssl_module开启ssl功能,但是作为nginx的核⼼功能,yum安装的nginx默认就是开启的。
官⽅⽂档: https://nginx.org/en/docs/http/ngx_http_ssl_module.html
配置参数如下:
ssl on | off; #为指定的虚拟主机配置是否启⽤ssl功能,此功能在1.15.0废弃,使⽤listen [ssl]替代。
ssl_certificate /path/to/file; #当前虚拟主机使⽤使⽤的公钥⽂件,⼀般是crt⽂件
ssl_certificate_key /path/to/file; #当前虚拟主机使⽤的私钥⽂件,⼀般是key⽂件
ssl_protocols [SSLv2] [SSLv3] [TLSv1] [TLSv1.1] [TLSv1.2]; #⽀持ssl协议版本,早期为ssl,现在是TSL,默认为后三个
ssl_session_cache off | none | [builtin[:size]] [shared:name:size]; #配置ssl缓存
off: 关闭缓存
none: 通知客⼾端⽀持ssl session cache,但实际不⽀持
builtin[:size]: 使⽤OpenSSL内建缓存,为每worker进程私有
[shared:name:size]: 在各worker之间使⽤⼀个共享的缓存,需要定义⼀个缓存名称和缓存空间⼤⼩,⼀兆可以存储4000个会话信息,多个虚拟主机可以使⽤相同的缓存名称。
ssl_session_timeout time; #客⼾端连接可以复⽤ssl session cache中缓存的有效时⻓,默认5m

4 实现多域名HTTPS
Nginx⽀持基于单个IP实现多域名的功能,并且还⽀持单IP多域名的基础之上实现HTTPS,其实是基于Nginx的SNI(Server Name Indication)功能实现,SNI是为了解决⼀个Nginx服务器内使⽤⼀个IP绑定多个域名和证书的功能,其具体功能是客⼾端在连接到服务器建⽴SSL链接之前先发送要访问站点的域名(Hostname),这样服务器再根据这个域名返回给客⼾端⼀个合适的证书。

关于favicon.ico
favicon.ico ⽂件是浏览器收藏⽹址时显⽰的图标,当客⼾端使⽤浏览器问⻚⾯时,浏览器会⾃⼰主动发起请求获取⻚⾯的favicon.ico⽂件,但是当浏览器请求的favicon.ico⽂件不存在时,服务器会记录404⽇志,⽽且浏览器也会显⽰404报错。
解决方法
将图标保存到指定的目录
[root@CentOS7-01 ~]#cat /apps/nginx/conf/vhosts/pc.conf
server {
listen 80;
server_name www.hechunping.tech;
location = /favicon.ico {
root html/image;
}
location /pc {
root html;
}
}
[root@CentOS7-01 ~]#systemctl reload nginx
安全选项
1 隐藏nginx版本号
更改nginx源码信息,将nginx服务版本号更改为HCPWS/1.1并重新编译nginx
[root@CentOS7-01 nginx-1.16.1]#sed -ir 's#Server: nginx#Server: HCPWS/1.1#' /root/nginx-1.16.1/src/http/ngx_http_header_filter_module.c
[root@CentOS7-01 nginx-1.16.1]#nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017

2 升级Openssl版本
⼼脏出⾎(英语:Heartbleed),也简称为⼼⾎漏洞,是⼀个出现在加密程序库OpenSSL的安全漏洞,该程序库⼴泛⽤于实现互联⽹的传输层安全(TLS)协议。它于2012年被引⼊了软件中,2014年4⽉⾸次向公众披露。只要使⽤的是存在缺陷的OpenSSL实例,⽆论是服务器还是客⼾端,都可能因此⽽受到***。此问题的原因是在实现TLS的⼼跳扩展时没有对输⼊进⾏适当验证(缺少边界检查),因此漏洞的名称来源于“⼼跳”(heartbeat)。该程序错误属于缓冲区过读,即可以读取的数据⽐应该允许读取的还多。
升级步骤
1)查看当前的Openssl版本
2)下载OpenSSL源码包并解压
[root@CentOS7-01 nginx-1.16.1]#wget -P /usr/local/src/ https://www.openssl.org/source/openssl-1.1.1d.tar.gz
[root@CentOS7-01 nginx-1.16.1]#tar xf /usr/local/src/openssl-1.1.1d.tar.gz
3)编译安装nginx并指定新版本OpenSSL路径
[root@CentOS7-01 nginx-1.16.1]#nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017

[root@CentOS7-01 nginx-1.16.1]#make -j lscpu |awk 'NR==4{print $2}' && make install
[root@CentOS7-01 nginx-1.16.1]#systemctl restart nginx
