常用命令

# 不重启服务的情况下，加载新的内容
nginx -s reload

# 测试配置是否写对了
nginx -t

# 查看状态
systemctl status nginx

ubuntu安装:

1.安装必备组件:

sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring

2.导入官方的nginx签名密钥，apt验证包的真实性:

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
    | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

3.验证下载的文件是否包含正确的密钥:

gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

4.输出应该包含完整的指纹573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62，如果指纹不一致，请删除文件。如下所示:

pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
      573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
uid                      nginx signing key <signing-key@nginx.com>

5.（推荐）安装稳定版本的nginx包设置apt存储库，请运行以下命令:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

6. 如果想使用最新版本的nginx包，运行以下命令:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

7.设置存储库绑定，优先选择我们的包而不是发行版提供的包:

echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
    | sudo tee /etc/apt/preferences.d/99nginx

8.安装nginx的命令如下:

sudo apt update
sudo apt install nginx

debian安装:
