1、下载并解压Nginx

# 创建安装目录（也可不创建，直接解压到/etc下）
mkdir -p /etc/nginx

# 下载 Nginx 源码包（请替换为最新版本）
wget http://nginx.org/download/nginx-1.22.1.tar.gz

# 解压源码包到 /etc/nginx
tar -zxvf nginx-1.22.1.tar.gz -C /etc/
mv /etc/nginx-1.22.1 /etc/nginx

2、编译并安装Nginx

cd /etc/nginx/nginx



# 配置编译选项
./configure \
--prefix=/etc/nginx \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx.pid \
--with-http_ssl_module

# 编译并安装
make
make install

3、创建Nginx配置文件

编辑 /etc/nginx/nginx.conf 文件，以下是基本配置示例：

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
}

4、创建systemd服务文件

创建 /etc/systemd/system/nginx.service 文件，内容如下：

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
ExecReload=/usr/sbin/nginx -s reload
ExecStop=/bin/sh -c "/usr/sbin/nginx -s quit"

[Install]
WantedBy=multi-user.target

5、启动Nginx

# 重新加载 systemd 配置
systemctl daemon-reload

<!-- more -->

# 启动 Nginx
systemctl start nginx

# 设置开机自启
systemctl enable nginx

# 查看 Nginx 状态
systemctl status nginx
# 重启 Nginx
systemctl restart nginx
