1.安装nginx
1.1 启动容器、download nginx 以及编译前的修改
启动容器
1 liwangdeMacBook-Air:~ liwang$ docker run -i -t --name nginx_server_01 -v /Users/liwang/docker/nginx_data:/data -p 80:80 centos /bin/bash
将文件copy至容器中
1 liwangdeMacBook-Air:~ liwang$ docker cp Downloads/nginx-1.14.0.tar.gz nginx_server_01:/soft/nginx-1.14.0.tar.gz
解压
1 [[email protected] soft]# tar xf /soft/nginx-1.14.0.tar.gz -C /soft/
安装之前修改源码屏蔽名称以及版本号
1 [[email protected] core]# ls -l "/soft/nginx-1.14.0/src/core/nginx.h" 2 -rw-r--r-- 1 1001 1001 476 Apr 17 15:22 /soft/nginx-1.14.0/src/core/nginx.h 3 [[email protected] core]# 4 5 ------------------------------------------------------ 6 #define NGINX_VERSION "0.0.1" 7 #define NGINX_VER "HaiYan/" NGINX_VERSION 8 #define NGINX_VAR "HaiYan" 9 ------------------------------------------------------ 10 #define NGINX_VERSION "1.14.0" 11 #define NGINX_VER "nginx/" NGINX_VERSION 12 #define NGINX_VAR "NGINX" 13 ------------------------------------------------------
1.2 安装nginx
安装插件
1 [[email protected] ~]# yum install pcre pcre-devel gcc gcc-c++ make openssl openssl-devel -y
添加用户
1 [[email protected] nginx-1.14.0]# useradd nginx -s /sbin/nologin -M
安装
1 [[email protected] nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --user=nginx --group=nginx 2 [[email protected] nginx-1.14.0]# make 3 [[email protected] nginx-1.14.0]# make install
启动nginx,利用curl工具获取服务器信息
1 [[email protected] conf]# /usr/local/nginx/sbin/nginx 2 [[email protected] nginx]# curl -I localhost 3 HTTP/1.1 200 OK 4 Server: HaiYan/0.0.1 5 Date: Tue, 01 May 2018 14:39:56 GMT 6 Content-Type: text/html 7 Content-Length: 612 8 Last-Modified: Tue, 01 May 2018 14:33:26 GMT 9 Connection: keep-alive 10 ETag: "5ae87ab6-264" 11 Accept-Ranges: bytes 12 13 [[email protected] nginx]#
详细可安装信息可用./configure --help获取
2.配置nginx
1、nginx虚拟主机配置
基于域名的虚拟主机
1 [[email protected] conf]# cat nginx.conf | grep -v "#" | grep -v "^$" >> extra/www.conf 2 修改www.conf效果如下: 3 [[email protected] extra]# cat www.conf 4 server { 5 listen 80; 6 server_name www.wang-li.top; 7 location / { 8 root html/www; 9 index index.html index.htm; 10 } 11 error_page 500 502 503 504 /50x.html; 12 location = /50x.html { 13 root html; 14 } 15 } 16 [[email protected] extra]#
修改nginx.conf 在http区间增加,include extra/*; 这行
1 [[email protected] conf]# cat nginx.conf | grep -v "#" | grep -v "^$" 2 worker_processes 1; 3 events { 4 worker_connections 1024; 5 } 6 http { 7 include mime.types; 8 default_type application/octet-stream; 9 sendfile on; 10 keepalive_timeout 65; 11 server { 12 listen 80; 13 server_name localhost; 14 location / { 15 root html; 16 index index.html index.htm; 17 } 18 error_page 500 502 503 504 /50x.html; 19 location = /50x.html { 20 root html; 21 } 22 } 23 include extra/*; 24 } 25 [[email protected] conf]#
增加html/www/index.html文件
1 [[email protected] conf]# ls /usr/local/nginx/html/www/index.html -l 2 -rw-r--r-- 1 root root 613 May 1 14:50 /usr/local/nginx/html/www/index.html 3 [[email protected] conf]#
修改hosts文件，访问信息如下
1 [[email protected] conf]# cat /etc/hosts | grep www.wang-li.top 2 127.0.0.1 www.wang-li.top 3 [[email protected] conf]# curl -I www.wang-li.top 4 HTTP/1.1 200 OK 5 Server: HaiYan/0.0.1 6 Date: Tue, 01 May 2018 14:54:41 GMT 7 Content-Type: text/html 8 Content-Length: 613 9 Last-Modified: Tue, 01 May 2018 14:50:21 GMT 10 Connection: keep-alive 11 ETag: "5ae87ead-265" 12 Accept-Ranges: bytes 13 14 [[email protected] conf]#
基于端口的虚拟主机
修改www.conf基于端口的访问，如下:
1 [[email protected] extra]# cat www.conf 2 server { 3 listen 8081; 4 server_name www.wang-li.top; 5 location / { 6 root html/www; 7 index index.html index.htm; 8 } 9 error_page 500 502 503 504 /50x.html; 10 location = /50x.html { 11 root html; 12 } 13 } 14 [[email protected] extra]#
reload nginx 访问如下
1 [[email protected] extra]# /usr/local/nginx/sbin/nginx -t 2 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok 3 nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful 4 [[email protected] extra]# /usr/local/nginx/sbin/nginx -s reload 5 [[email protected] extra]# curl -I www.wang-li.top:8081 6 HTTP/1.1 200 OK 7 Server: HaiYan/0.0.1 8 Date: Tue, 01 May 2018 14:56:48 GMT 9 Content-Type: text/html 10 Content-Length: 613 11 Last-Modified: Tue, 01 May 2018 14:50:21 GMT 12 Connection: keep-alive 13 ETag: "5ae87ead-265" 14 Accept-Ranges: bytes 15 16 [[email protected] extra]#
基于IP的虚拟主机
获取容器ip
1 liwangdeMacBook-Air:~ liwang$ docker inspect -f {{.NetworkSettings.IPAddress}} nginx_server_01 2 172.17.0.2 3 liwangdeMacBook-Air:~ liwang$
修改www.conf如下
1 [[email protected] extra]# cat www.conf 2 server { 3 listen 172.17.0.2:8082; 4 server_name www.wang-li.top; 5 location / { 6 root html/www; 7 index index.html index.htm; 8 } 9 error_page 500 502 503 504 /50x.html; 10 location = /50x.html { 11 root html; 12 } 13 } 14 [[email protected] extra]#
reload后访问如下:
1 [[email protected] extra]# curl -I 172.17.0.2:8082 2 HTTP/1.1 200 OK 3 Server: HaiYan/0.0.1 4 Date: Tue, 01 May 2018 15:00:44 GMT 5 Content-Type: text/html 6 Content-Length: 613 7 Last-Modified: Tue, 01 May 2018 14:50:21 GMT 8 Connection: keep-alive 9 ETag: "5ae87ead-265" 10 Accept-Ranges: bytes 11 12 [[email protected] extra]#
2、nginx stub_status配置
查看系统是否支持此模块
1 [[email protected] extra]# /usr/local/nginx/sbin/nginx -V 2 nginx version: HaiYan/0.0.1 3 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 4 built with OpenSSL 1.0.2k-fips 26 Jan 2017 5 TLS SNI support enabled 6 configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --user=nginx --group=nginx 7 [[email protected] extra]#
发现有--with-http_stub_status_module就是支持的
配置www.conf如下:
1 [[email protected] extra]# cat www.conf 2 server { 3 listen 80; 4 server_name www.wang-li.top; 5 location / { 6 # root html/www; 7 # index index.html index.htm; 8 stub_status on; 9 access_log off; 10 } 11 } 12 [[email protected] extra]#
reload后访问如下
1 [email protected] extra]# curl www.wang-li.top 2 Active connections: 3 3 server accepts handled requests 4 21 21 20 5 Reading: 0 Writing: 1 Waiting: 2 6 [[email protected] extra]#
三个值分别代表：
active connections:正在处理的连接活动数
21 21 20
第一个表示从启动到现在一共处理了21次请求
第二个表示建立了21次握手
第三个表示总共处理了20次请求
丢包数 = 握手数-连接数 可见，并未丢包
reading: nginx 读取到客户端的header信息数
writing: Nginx 返回给客户端的header信息数
waiting: Nginx 处理完等待下一次请求指令的驻留连接，在开启keep-alive的情况下，这个值等于active - (reading + writing)
3、nginx_location:
作用：根据不同的URI来执行不同的应用
语法:
location [ = | ~ | ~* | ^- ] url {
...
}
语法规则： location [=|~|~*|^~] /uri/ { … }
= 开头表示精确匹配
^~ 开头表示uri以某个常规字符串开头，理解为匹配 url路径即可。nginx不对url做编码，因此请求为/static/20%/aa，可以被规则^~ /static/ /aa匹配到（注意是空格）。
~ 开头表示区分大小写的正则匹配
~* 开头表示不区分大小写的正则匹配
!~和!~*分别为区分大小写不匹配及不区分大小写不匹配 的正则
/ 通用匹配，任何请求都会匹配到。
~和~*的区别: ~区分大小写， ~* 不区分大小写
= :为精确配置
/ :为默认配置
案例:
利用location来实现根据URI来访问不同的内容，实现功能:访问www.wang-li.top/bbs/XXX时，能够抓取和www.wang-li.top不同的位置
配置如下
1 [[email protected] conf]# sed -n "47,59p" nginx.conf 2 3 location ^~ /bbs/ { 4 root html/bbs; 5 index index.html; 6 # 7 } 8 9 location / { 10 root html; 11 index index.html index.htm; 12 # 13 } 14 [[email protected] conf]# tree /usr/local/nginx/html/ 15 /usr/local/nginx/html/ 16 |-- 50x.html 17 |-- bbs 18 | `-- bbs 19 | `-- index.html 20 |-- index.html 21 `-- www 22 `-- index.html 23 24 3 directories, 4 files 25 [[email protected] conf]#
访问如下:
1 [[email protected] conf]# curl localhost 2 <!DOCTYPE html> 3 <html> 4 <head> 5 <title>Welcome to nginx!</title> 6 <style> 7 body { 8 width: 35em; 9 margin: 0 auto; 10 font-family: Tahoma, Verdana, Arial, sans-serif; 11 } 12 </style> 13 </head> 14 <body> 15 <h1>Welcome to nginx!</h1> 16 <p>If you see this page, the nginx web server is successfully installed and 17 working. Further configuration is required.</p> 18 19 <p>For online documentation and support please refer to 20 <a href="http://nginx.org/">nginx.org</a>.<br/> 21 Commercial support is available at 22 <a href="http://nginx.com/">nginx.com</a>.</p> 23 24 <p><em>Thank you for using nginx.</em></p> 25 </body> 26 </html> 27 [[email protected] conf]# curl localhost/bbs/ 28 Welcome www.wang-li.top PPS 29 [[email protected] conf]#
4、nginx alias 和 root的区别
基于上诉的nginx location,location 和 alias的差别就在于
root会带入上诉的url路径去判断，而alias则不会，举例:
location ^~ /bbs/ {
root html/bbs;
index index.html;
#
}
这段说明:当我的url中包含bbs时，会去执行location的内容，而内容包含root html/bbs,现在如果输入localhost\\bbs\\时，系统会去检查本地文件html/bbs/bbs/...这下面的内容
而alias则不会
修改如下:
1 [[email protected] bbs]# sed -n "48,58p" /usr/local/nginx/conf/nginx.conf 2 location ^~ /bbs/ { 3 alias html/bbs/; 4 index index.html; 5 # 6 } 7 8 location / { 9 root html; 10 index index.html index.htm; 11 # 12 } 13 [[email protected] bbs]# cat /usr/local/nginx/html/bbs/index.html 14 alias liwag bbs site 15 [[email protected] bbs]# 16 [[email protected] bbs]# curl localhost/bbs/ 17 alias liwag bbs site 18 [[email protected] bbs]#
5、nginx rewrite:
语法:
rewrite ^/(.*) url/$1 permanent;
意思是只要匹配如下^/(.*)，就跳转至url上，且$1是取前面regex部分括号的内容，结尾的primanent是永久301重定向标记。
regex语法:
\\：去掉特殊字符
^：起始位置
$：结束位置
*：匹配0次或多次
+：匹配前面的字符一次或多次
?:匹配前面的字符0次或1次
.:匹配\\n之外的任何字符
(pattern):匹配括号内字符，并可以在后面匹配，常用$0-$9属性获取值
rewrite flag标记
last:本条规则匹配完成后，继续向下匹配
break:本条规则匹配完成后，不再匹配后面的规则
redirect:返回302临时重定向，
permanent:返回301永久重定向
例子,为实现需求，访问 网址/blog 时跳转至www.cnblogs.com:
1 [[email protected] conf]# sed -n "33,39p" nginx.conf 2 #gzip on; 3 4 server { 5 listen 80; 6 server_name localhost; 7 8 rewrite ^/(.*)/blog http://www.cnblogs.com/$1 permanent; 9 [[email protected] conf]# curl -I localhost/wang-li/blog 10 HTTP/1.1 301 Moved Permanently 11 Server: HaiYan/0.0.1 12 Date: Fri, 11 May 2018 14:44:12 GMT 13 Content-Type: text/html 14 Content-Length: 185 15 Connection: keep-alive 16 Location: http://www.cnblogs.com/wang-li 17 18 [[email protected] conf]#
3.nginx调优
1.修改默认用户，有两种方式其一是修改nginx.conf中的内容，但是事先用户必须在系统中存在，其二为编译时就指定用户和用户组
其一：
1 [[email protected] conf]# grep "nginx" /etc/passwd 2 nginx:x:1000:1000::/home/nginx:/sbin/nologin 3 [[email protected] conf]# sed -n "3,6p" nginx.conf 4 user nginx nginx; 5 worker_processes 1; 6 7 #error_log logs/error.log; 8 [[email protected] conf]#
其二:
1 [[email protected] conf]# /usr/local/nginx/sbin/nginx -V 2 nginx version: HaiYan/0.0.1 3 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 4 built with OpenSSL 1.0.2k-fips 26 Jan 2017 5 TLS SNI support enabled 6 configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --user=nginx --group=nginx 7 [[email protected] conf]#
在编译时指定user和group
2.设置nginx worker cpu核数和cpu affinity
设置nginx worker cpu核数一般设置为系统CPU核数或者是其倍数
查看系统cpu核数
1 [[email protected] conf]# cat /proc/cpuinfo | grep processor | wc -l 2 2 3 [[email protected] conf]#
修改后nginx worker为:
1 [[email protected] conf]# sed -n "3,6p" nginx.conf 2 worker_processes 4; 3 4 #error_log logs/error.log; 5 #error_log logs/error.log notice; 6 [[email protected] conf]#
cpu affinity([??f?n?ti])的目的是为了设置cpu分布,让其均匀分布在各个cpu上
配置如下:
1 [[email protected] conf]# sed -n "3,5p" nginx.conf 2 worker_processes 4; 3 worker_cpu_affinity 00000001 00000010 00000011 00000100; 4 5 [[email protected] conf]#
配置之后top命令如下:
1 [[email protected] conf]# top -n 1 2 3 top - 16:35:56 up 3:12, 0 users, load average: 0.00, 0.00, 0.00 4 Tasks: 7 total, 1 running, 6 sleeping, 0 stopped, 0 zombie 5 %Cpu(s): 3.2 us, 0.0 sy, 0.0 ni, 96.8 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st 6 KiB Mem : 2046976 total, 398764 free, 224528 used, 1423684 buff/cache 7 KiB Swap: 1048572 total, 1048572 free, 0 used. 1646940 avail Mem 8 9 PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10 1 root 20 0 11784 2936 2492 S 0.0 0.1 0:00.56 bash 11 185 root 20 0 45932 3612 2588 S 0.0 0.2 0:00.01 nginx 12 279 nginx 20 0 73068 30652 2492 S 0.0 1.5 0:00.00 nginx 13 280 nginx 20 0 73068 30652 2492 S 0.0 1.5 0:00.00 nginx 14 281 nginx 20 0 73068 30652 2492 S 0.0 1.5 0:00.00 nginx 15 282 nginx 20 0 73068 30616 2456 S 0.0 1.5 0:00.00 nginx 16 283 root 20 0 51908 3676 3152 R 0.0 0.2 0:00.00 top
3.调整nginx 工作模式为epoll，来处理高并发事件
1 [[email protected] conf]# sed -n "12,17p" nginx.conf 2 3 events { 4 use epoll; 5 worker_connections 1024; 6 } 7 8 [[email protected] conf]#
4.设置nginx worker进程最大打开文件描述符数目,最好还是与系统ulimit保持一致
1 [[email protected] conf]# ulimit -n 2 1048576 3 [[email protected] conf]#
配置conf如下:
1 [[email protected] conf]# sed -n "3,6p" nginx.conf 2 worker_processes 4; 3 worker_cpu_affinity 00000001 00000010 00000011 00000100; 4 worker_rlimit_nofile 1048576; 5 6 [[email protected] conf]#
5.配置nginx最多的连接数
配置如下:
1 [[email protected] conf]# sed -n "10,20p" nginx.conf 2 3 #pid logs/nginx.pid; 4 5 6 events { 7 use epoll; 8 worker_connections 65535; 9 } 10 11 12 http { 13 [[email protected] conf]#
6.优化超时连接时间
当超过设定时间还未连接成功的话，则会断开
1 [[email protected] conf]# sed -n "30,35p" nginx.conf 2 sendfile on; 3 #tcp_nopush on; 4 5 #keepalive_timeout 0; 6 keepalive_timeout 60; 7 8 [[email protected] conf]#
7.优化客户端请求头超时时间以及请求body超时时间
此设置主要是为了防止客户端利用http进行攻击,如果在设置时间内没有发送完整的header或则body,则会返回request time out错误
1 [[email protected] conf]# sed -n "34,39p" nginx.conf 2 keepalive_timeout 60; 3 4 client_header_timeout 30; 5 client_body_timeout 60; 6 7 #gzip on; 8 [[email protected] conf]#
8.优化客户端超时时间
如果超过设置时间，客户端还未有任何动作，nginx则会断掉此连接
1 [[email protected] conf]# sed -n "34,39p" nginx.conf 2 keepalive_timeout 60; 3 4 client_header_timeout 30; 5 client_body_timeout 60; 6 send_timeout 30; 7 8 [[email protected] conf]#
附上nginx.conf如下(仅供参考)
1 [[email protected] conf]# cat nginx.conf | grep -v "^$" | grep -v "#" 2 worker_processes 4; 3 worker_cpu_affinity 00000001 00000010 00000011 00000100; 4 worker_rlimit_nofile 1048576; 5 events { 6 use epoll; 7 worker_connections 65535; 8 } 9 http { 10 include mime.types; 11 default_type application/octet-stream; 12 sendfile on; 13 keepalive_timeout 60; 14 client_header_timeout 30; 15 client_body_timeout 60; 16 send_timeout 30; 17 server { 18 listen 80; 19 server_name localhost; 20 rewrite ^/(.*)/blog http://www.cnblogs.com/$1 permanent; 21 22 23 location ^~ /bbs/ { 24 alias html/bbs/; 25 index index.html; 26 } 27 location / { 28 root html; 29 index index.html index.htm; 30 } 31 }} 32 [[email protected] conf]#
4.性能测试
利用ab压力测试工具进行测试结果如下:
1 [[email protected] conf]# ab -c 10 -n 10000 localhost/ 2 参数说明，-c 为并发数 -n 为总请求数 总请求数需要大于并发数 3 This is ApacheBench, Version 2.3 <$Revision: 1430300 $> 4 Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ 5 Licensed to The Apache Software Foundation, http://www.apache.org/ 6 上述介绍ab工具版本等等信息 7 8 Benchmarking localhost (be patient) 9 Completed 1000 requests 10 Completed 2000 requests 11 Completed 3000 requests 12 Completed 4000 requests 13 Completed 5000 requests 14 Completed 6000 requests 15 Completed 7000 requests 16 Completed 8000 requests 17 Completed 9000 requests 18 Completed 10000 requests 19 Finished 10000 requests 20 21 22 Server Software: HaiYan/0.0.1 23 Server Hostname: localhost 24 Server Port: 80 25 show 出服务器信息以及访问信息端口等 26 27 Document Path: / 28 Document Length: 52273 bytes 29 请求路劲以及文件大小 30 31 Concurrency Level: 10 32 Time taken for tests: 1.024 seconds 33 整个测试持续的时间 34 Complete requests: 10000 35 完成的请求数量 36 Failed requests: 0 37 失败数 38 Write errors: 0 39 Total transferred: 525090000 bytes 40 HTML transferred: 522730000 bytes 41 Requests per second: 9769.13 [#/sec] (mean) 42 平均返回数据时间 43 Time per request: 1.024 [ms] (mean) 44 平均响应时间 45 Time per request: 0.102 [ms] (mean, across all concurrent requests) 46 平均并发响应时间 47 Transfer rate: 500944.38 [Kbytes/sec] received 48 49 Connection Times (ms) 50 min mean[+/-sd] median max 51 Connect: 0 0 0.1 0 2 52 Processing: 0 1 0.2 1 3 53 Waiting: 0 0 0.2 0 2 54 Total: 0 1 0.2 1 3 55 56 响应时间的值 57 58 Percentage of the requests served within a certain time (ms) 59 50% 1 60 66% 1 61 75% 1 62 80% 1 63 90% 1 64 95% 1 65 98% 2 66 99% 2 67 100% 3 (longest request) 68 请求的平均速度 69 [[email protected] conf]#
