Nginx 编译安装

准备环境与依赖库#

在编译之前先要明白自己的需求, 比如我现在需要 https / http2 和挂多个 HTTPS 域名, 那在编译 Nginx 之前首先就要安装构建工具和 Nginx 依赖的库。

sudo apt update

sudo apt install -y build-essential \
libssl-dev libpcre3-dev \
zlib1g-dev \
wget

注意：安装 libssl-dev 是确保 TLS SNI support enabled 的关键，因为它提供了编译所需的 OpenSSL 开发头文件。

下载 Nginx 源码#

我选定的版本是 1.26.3, 前往自己喜欢的目录去拉取对应版本的源码包。

wget https://nginx.org/download/nginx-1.26.3.tar.gz
tar -zxvf nginx-1.26.3.tar.gz
cd nginx-1.26.3

配置编译参数#

接下来将安装路径指向自定义目录, 比如我这里指定的是 /usr/local/nginx 目录。

./configure --prefix=/usr/local/nginx \
--pid-path=/usr/local/nginx/logs/nginx.pid \
--with-http_ssl_module \
--with-http_v2_module \
--with-cc-opt="-I/usr/include" \
--with-ld-opt="-L/usr/lib"

关于 TLS SNI Support: 只要你的系统 openssl 版本不低于 0.9.8f（Ubuntu 20.04+ 通常是 1.1.1 或 3.0+），在 configure 阶段会自动检测并显示 TLS SNI support enabled。

编译/安装/验证#

编译和安装。

make -j$(nproc)

sudo make install

检查 Nginx 是否安装成功。

/usr/local/nginx/sbin/nginx -V

nginx version: nginx/1.26.3
built by gcc 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04.3)
built with OpenSSL 3.0.2 15 Mar 2022
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_v2_module --with-cc-opt=-I/usr/include --with-ld-opt=-L/usr/lib

允许免密登录#

修改 ssh 配置文件, 允许公钥登录。

vim /etc/ssh/sshd_config

PubkeyAuthentication no → PubkeyAuthentication yes

重启 ssh 服务

systemctl restart ssh

开机自启 nginx 服务#

创建 Nginx 的 systemd 服务配置文件。

sudo vim /etc/systemd/system/nginx.service

输入以下内容：

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=network.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid

ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit

PrivateTmp=true

[Install]
WantedBy=multi-user.target

重新加载 systemd 配置并启动 Nginx 服务。

sudo systemctl daemon-reload

sudo systemctl start nginx

查看 Nginx 服务当前的运行状态。

sudo systemctl status nginx

设置开机自启

sudo systemctl enable nginx

成功提示：
