一、Nginx的源码编译

1.下载软件

复制代码 
[root@Nginx ~]# wget https://nginx.org/download/nginx-1.28.1.tar.gz

2.解压

复制代码 
[root@Nginx ~]# tar zxf nginx-1.28.1.tar.gz
[root@Nginx ~]# cd nginx-1.28.1/
[root@Nginx nginx-1.28.1]# ls
auto     CHANGES.ru          conf       contrib          html     man        SECURITY.md
CHANGES  CODE_OF_CONDUCT.md  configure  CONTRIBUTING.md  LICENSE  README.md  src

3.检测环境

复制代码 
#安装依赖性
[root@Nginx ~]# dnf install gcc openssl-devel.x86_64 pcre2-devel.x86_64 zlib-devel -y

[root@Nginx nginx-1.28.1]# ./configure --prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_v2_module \
--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 \

4.编译

复制代码 
[root@Nginx nginx-1.28.1]# make
[root@Nginx nginx-1.28.1]# make install

5.nginx启动

复制代码 
#设定环境变量
[root@Nginx nginx-1.28.1]# cd /usr/local/nginx/sbin
[root@Nginx sbin]# vim  ~/.bash_profile
export PATH=$PATH:/usr/local/nginx/sbin

[root@Nginx sbin]# source   ~/.bash_profile

[root@Nginx sbin]# cd /usr/local/nginx/logs
[root@Nginx logs]# useradd  -s /sbin/nologin -M nginx
[root@Nginx logs]# nginx
[root@Nginx logs]# ps aux | grep nginx
root       44012  0.0  0.1  14688  2356 ?        Ss   17:01   0:00 nginx: master process nginx
nginx      44013  0.0  0.2  14888  3892 ?        S    17:01   0:00 nginx: worker process
root       44015  0.0  0.1   6636  2176 pts/0    S+   17:01   0:00 grep --color=auto nginx


#测试
[root@Nginx logs]# echo timinglee > /usr/local/nginx/html/index.html

[root@Nginx logs]# curl  172.25.254.100
timinglee

6.编写启动文件

复制代码 
[root@Nginx ~]# vim /lib/systemd/system/nginx.service
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]

ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

[root@Nginx ~]# systemctl daemon-reload

#验证
[root@Nginx ~]# systemctl status nginx.service
○ nginx.service - The NGINX HTTP and reverse proxy server
     Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; preset: disabled)
     Active: inactive (dead)

[root@Nginx ~]# systemctl enable --now nginx
[root@Nginx ~]# ps aux | grep nginx
root        1839  0.0  0.1  14688  2356 ?        Ss   09:53   0:00 nginx: master process /usr/local/nginx/sbin/nginx
nginx       1840  0.0  0.2  14888  3828 ?        S    09:53   0:00 nginx: worker process

[root@Nginx ~]# reboot
[root@Nginx ~]# systemctl status nginx.service

二、Nginx的平滑升级及回滚

1.下载高版本的软件

root@Nginx \~# wget https://nginx.org/download/nginx-1.29.4.tar.gz

2.对于新版本的软件进行源码编译并进行平滑升级

#编译nginx隐藏版本

root@Nginx \~# tar zxf nginx-1.29.4.tar.gz

root@Nginx \~# cd nginx-1.29.4/src/core/

root@Nginx core# vim nginx.h

#define nginx_version 1029004

#define NGINX_VERSION ""

#define NGINX_VER "TIMINGLEE/" NGINX_VERSION

#文件编辑完成后进行源码编译即可

三、Nginx配置文件的管理及优化参数

root@Nginx ~]# vim /usr/local/nginx/conf/nginx.conf

user nginx;

root@Nginx \~# nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

root@Nginx \~# nginx -s reload

root@Nginx \~# ps aux | grep nginx

root 5506 0.0 0.2 14564 3912 ? Ss 14:40 0:00 nginx: master process /usr/local/nginx/sbin/nginx

nginx 5511 0.0 0.2 14996 4032 ? S 14:41 0:00 nginx: worker process

root@Nginx \~# vim /usr/local/nginx/conf/nginx.conf

worker_processes 2;

root@Nginx \~# nginx -s reload

root@Nginx \~# ps aux | grep nginx

root 5506 0.0 0.2 14796 4040 ? Ss 14:40 0:00 nginx: master process /usr/local/nginx/sbin/nginx

nginx 5516 0.0 0.2 15012 4048 ? S 14:42 0:00 nginx: worker process

nginx 5517 0.0 0.2 15012 4048 ? S 14:42 0:00 nginx: worker process

#在vmware中更改硬件cpu核心个数，然后重启

root@Nginx \~# vim /usr/local/nginx/conf/nginx.conf

worker_processes auto;

worker_cpu_affinity 0001 0010 0100 1000;

root@Nginx \~# ps aux | grep nginx

root 887 0.0 0.1 14564 2212 ? Ss 14:51 0:00 nginx: master process /usr/local/nginx/sbin/nginx

nginx 889 0.0 0.2 14964 3748 ? S 14:51 0:00 nginx: worker process

四、Nginx下构建PC站点

1.location中的root

复制代码 
[root@Nginx conf]# cd /usr/local/nginx/conf/
[root@Nginx conf]# mkdir  conf.d
[root@Nginx conf]# vim nginx.conf
82     include "/usr/local/nginx/conf/conf.d/*.conf";

[root@Nginx conf]# nginx -s reload
[root@Nginx conf]# cd conf.d/

[root@Nginx ~]# mkdir  -p /webdata/nginx/timinglee.org/lee/html
[root@Nginx ~]# echo lee.timinglee.org > /webdata/nginx/timinglee.org/lee/html/index.html

[root@Nginx conf.d]# vim vhosts.conf
server {
    listen 80;
    server_name lee.timinglee.org;
    location / {
        root /webdata/nginx/timinglee.org/lee/html;
    }
}

root@Nginx conf.d]# systemctl restart nginx.service

#测试
[root@Nginx conf.d]# vim /etc/hosts
172.25.254.100     Nginx www.timinglee.org lee.timinglee.org

[root@Nginx conf.d]# curl  www.timinglee.org
timinglee
[root@Nginx conf.d]# curl  lee.timinglee.org
lee.timinglee.org

#local示例需要访问lee.timinglee.org/lee/目录
[root@Nginx conf.d]# vim vhosts.conf
server {
    listen 80;
    server_name lee.timinglee.org;
    location / {
        root /webdata/nginx/timinglee.org/lee/html;
    }
    location /lee {            #lee标识location中的root值+location 后面指定的值代表目录的路径
        root /webdata/nginx/timinglee.org/lee/html;
    }
    
}

[root@Nginx conf.d]# systemctl restart nginx.service
[root@Nginx conf.d]# mkdir  -p /webdata/nginx/timinglee.org/lee/html/lee
[root@Nginx conf.d]# echo lee > /webdata/nginx/timinglee.org/lee/html/lee/index.html
[root@Nginx conf.d]# curl  lee.timinglee.org/lee/
lee

2.location中的alias

root@Nginx conf.d# vim vhosts.conf

server {

listen 80;

server_name lee.timinglee.org;

location /passwd { #标识文件

alias /etc/passwd;

}

location /passwd/ { #表示目录

alias /mnt/;

}

}

root@Nginx conf.d# nginx -s reload

root@Nginx conf.d# echo passwd > /mnt/index.html

#测试

root@Nginx conf.d# curl lee.timinglee.org/passwd/

passwd

root@Nginx conf.d# curl lee.timinglee.org/passwd

root:x:0:0:root:/root:/bin/bash

bin:x:1:1:bin:/bin:/sbin/nologin

daemon:x:2:2:daemon:/sbin:/sbin/nologin

五、KeepAlived长链接优化

1.设定长链接时间

复制代码 
[root@Nginx ~]# vim /usr/local/nginx/conf/nginx.conf
keepalive_timeout   5;
[root@Nginx ~]# nginx -s reload

#测试
[root@Nginx ~]# dnf install telnet -y
[root@Nginx ~]# telnet www.timinglee.org 80
Trying 172.25.254.100...
Connected to www.timinglee.org.
Escape character is '^]'.
GET / HTTP/1.1     <<<<
Host: www.timinglee.org    <<<<
							<<<
HTTP/1.1 200 OK
Server: nginx/1.28.1
Date: Sat, 31 Jan 2026 08:27:02 GMT
Content-Type: text/html
Content-Length: 10
Last-Modified: Thu, 29 Jan 2026 09:02:15 GMT

ETag: "697b2217-a"
Accept-Ranges: bytes

timinglee    显示的页面出现后根据设定的长链接时间会等待，超过时间后会自动退出
Connection closed by foreign host.

2.设定长链接次数

root@Nginx \~# vim /usr/local/nginx/conf/nginx.conf
keepalive_requests 3;

root@Nginx \~# nginx -s reload

#测试

root@Nginx \~# telnet www.timinglee.org 80

Trying 172.25.254.100...

Connected to www.timinglee.org.

Escape character is '^]'.
GET / HTTP/1.1 #需要自己输入然后回车
Host: www.timinglee.org
