ubuntu18.04安装nginx

如何在 ubuntu18.04安装nginx ？

参考官方文档：http://nginx.org/en/linux_packages.html#Ubuntu

稳定版安装示例：

• Install the prerequisites（安装必备组件）:

  sudo apt install curl gnupg2 ca-certificates lsb-release

  

• To set up the apt repository for stable nginx packages, run the following command（要为稳定的nginx包设置apt存储库，请运行以下命令）:

  echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
      | sudo tee /etc/apt/sources.list.d/nginx.list

  

• Next, import an official nginx signing key so apt could verify the packages authenticity（接下来，导入一个官方nginx签名密钥，以便apt能够验证包的真实性）:

  curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -

  

• Verify that you now have the proper key（确认您现在有正确的钥匙）:

  sudo apt-key fingerprint ABF5BD827BD9BF62

• The output should contain the full fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 as follows（输出应包含完整指纹573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62，如下所示）:

  pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
        573B FD6B 3D8F BC64 1079  A6AB ABF5 BD82 7BD9 BF62
  uid   [ unknown] nginx signing key <signing-key@nginx.com>

  

• To install nginx, run the following commands（要安装nginx，请运行以下命令）:

  sudo apt update
  sudo apt install nginx

  

  

  到这里就已经安装成功了。

• 启动nginx

  sudo /etc/init.d/nginx start

  

• 查看nginx状态

  sudo /etc/init.d/nginx status

  

• 更多用法
  每当修改了nginx配置文件后，先执行

  sudo /etc/init.d/nginx configtest

  再执行

  sudo /etc/init.d/nginx check-reload

• 测试
  

  curl -I localhost
